This was a terrific job! Thoroughly enjoyed watching the entire video. I know it was a great feeling when the car started up and everything was good to go. Very resourceful and impressed with your persistence. Thanks for sharing the experience. Just started watching your new video on the Smart Top Controller. Looks like a great upgrade for my 2015 911S cab.
Cabby thank you!! I’d say the feeling was “ thoroughly relieved” lol. That was the most involved project I’ve done. The center radiator project and breaks were also big jobs for me, but the plenum takes the cake. Thanks for the comment and kind words!
Excellent job Bro. Very thorough, and methodical. Few mechanics will spend this kind of time and attention to detail for a car they don’t own.
There is no substitute for doing it yourself, learning about your car, and knowing it was done carefully. I always like to lay a towel over “drop zones” when I am removing screws or working with small tools, etc. Sometimes searching for a screw takes more time than the job itself, as they always find the smallest, hardest to find places, to land, lol.
rick scriver thank you! Great tip on the towel. Also covering easy to scratch zones! That I didn’t do.
Did the plenum on my 996 C4S a few yrs back. Messed up the gasket seal at the back and on restart had a huge vacuum leak . My indi shop saved me and had a bit of a laugh at my panic. Just ordered the plenum, intake and centre muffler delete for my recent 997.2 C4S. You’ve given me the courage to go back in there. Thnx for sharing your experience. Ton of work doing those videos.
Terry Ledden thank you! This car has been such a great project. Doesn’t feel like work at all! Lol. Thanks for the comment.
Porsche wrenching for Everyman! Finally, a presenter who lays it all out there as not all a “piece of cake”. Great job! Now I want to replace the throttle body and intake plenum on mine!
Frank Mummolo thank you! It was a great project. Everything is still working, about 10,000 miles later. Haven’t had a single problem.
You did a great Job it took a minute but you never gave up and you showed everyone out there how to change theirs if they want to Thank you for posting this video Sounds Great ** Porsche There is no Substitute #1
Thanks! Agreed
I just had AOS failure on my 987S and had to tackle all the clean up and repair myself..BUT at least I had access to top of the motor. Kudos to your patience and resolve. Good job
kam1996 thanks!!
I am impressed! Way to stick with it & get it done.
I was just in Florida for a couple of weeks- love it down there.
Thanks
Coming from a porsche dealer technician. Impressed, good job!
Thank you!
I know how difficult this is , I fitted the IPD on my 997.2 , which has a bit better access. The engine drop is still the way to go, I hadn't tried that and messed around for two days. I succeeded by using a teflon lubricant spray to make the rubber boots slippery , and that also helped a lot as they slide on easily. Great that you have recorded and shared this video. I think overall it is a good mod, smoother delivery through the power range. It must be those golf ball dimples ! .... Well Done, this is really good inspiration for Car enthusiasts ... Worth the extra grey hairs .......If at first you don't succeed TRY TRY again..
tpmbe thank you! I totally agree the power delivery seems to be much more instantaneous. Please check out my other videos I did the exhaust and a Cobb tune and then Fabspeed tune once all of the mechanical mods were completed. Anyway I appreciate your comment this was by far one of the most ambitious projects I’ve done.
Wow. You are very brave. I have rebuilt both 2-stroke and 4-stroke motorcycle engines and tinker on the car a little but that was next level.
Thank you! Or stupid lol
I have owned a 991S Cab for four years and the sound with the top down is as you say 'intoxicating' and mine is standard!
Nice!
Really informative vid congrats! I hate plastic intakes and this is definitely a great mod consideration for my 997.2 S
Thank you!
amazing you took this on and won! suscribed!
Lewis Junior two months in and all is running perfectly. Thanks for the comment!
very impressive - you hung in there and gotter done - sounds great
Ken Korach thank you! Third center radiator install and Giro Disk rotors next!
Very detailed video. Thank you. Amazing footage
Glad you enjoyed it! Thank you!
Wow, makes me appreciate my 997 a little more.
I was thinking the same thing lol.
Thanks
I really liked this video. Rubber seals and clamps were often referred to as a, "thing" or things. It didn't matter. Each item and problem that you went through to replace the plenum. The lowering of the motor may be the main thing. Motor mount nut torque is a great idea. That aluminum does increase sound over plastic. Fab Speed custom tune. Seems like the Fab Speed tool provides a good general increase and going through data logging etc. might only get another couple of horses over the tunes that they've already figured out and are available with the tune. I have standard air filters; Fab speed exhaust bought and installed when I bought the car in 2012. That leaves the plenum install and the tune. The tune can go back to stock for DMV. But I wonder if I can pass smog with the new plenum, not so much because it won't be clean enough, but because the california smog station will detect and new plenum without a CARB number. They want a California Air Resources Number for anything in the intake or exhaust system at cats and back to the engine. Overall, this was one of the best, "how-to," videos I've ever seen. Despite my advanced age of 74, It makes me believe I could possibly do this. Another thing to do in advance is go to the dealer and see if the service bulletin applies to my 2012 991 on that oil/air separator. I wonder if it was all down, if i could then pay them a small fee for putting in the plenum, considering how much has to be removed to get to the oil/air separator? At any rate, you didn't always give the size of the torx sockets, nor the clearance amount you had to remove to create the proper tool for getting into that tight space. Then it looks like you got a piece of 1 X 4, the width of the jack pad and the length of the underneath of the oil pan? I should get one of those in advance. I didn't see the use of any jack stands, but I may have missed that as you did the job. None the less, let me give you a thumbs up. By watching this again, I can complete the notes I took on your installation of the plenum. I also liked the way you maintained as many vacuum hoses as possible, in place, so as not to mix them up. I'm guessing that different color tapes, blue, green, red, black and perhaps some digital photos of your steps might have helped there. Still, you are the owner of your car and you were able to show how it is done. I for one, really appreciate all the effort you went to, to video this. AF
Alex Ford thanks so much!! This was the most intimidating projects I have done on this car. Taking the stereo apart to install the reverse camera electronic boards was number two. Unfortunately I don’t have the vocabulary for these videos. I just don’t know what the stuff is called and in most cases when I do know what it’s called I don’t remember in the heat of the moment on video. I also do not possess the ability to look at a nut or bolt and know the size. I have to go back-and-forth with the tool and by the time I have found the one that fits I don’t even think about the size. Anyway these are fun projects for me and I enjoy documenting them through CZcams. I really appreciate you watching and your comments are motivating. The combination of Plenum filters tune and headers/cats with the factory PSE has produced power and responsiveness that I am thrilled with. I have no desire to do anything else to this motor. As far as California emissions, maybe call Fabspeed. It would seem they have sold to California owners and would have some information on the likeliness of passing. I’m sure it’s very frustrating dealing with all the rules!! Thank you again and good luck with your car!
So I just told my "friend " that I would help him do this exact same install on his car. He told me I could drink all the beer I wanted. I think he's going to have to spring for a steak dinner though. So Snap On has some tools made to help in removal of hoses that would work on those plenum seals. Looks like a u shaped big pick looking thing. Anyhow great video. Going to tell him about the oil separator. Best to have it on hand just in case.
Timothy Thompson this was a great project and really not all that complicated. Just a lot of steps! The tool sounds like it a good investment. The re installation of those baffles was a pain. You’re a good friend!! Enjoy the beer and steak!
The sum parts together with the tune is what makes all the difference.
A Google User you’re totally right! Thanks for the comment.
I m impressed...you're the man....
Hazard David thank you! Nerve racking project!!
YOLOfotos honestly, I was kinda holding my breath couple of times...😅...subscribed
Hazard David hahaha. Me too. The dropping the motor part was freaking me out. Getting the bellows back on the most difficult part. Great news is everything is working perfectly. Snappy performance. Zero problems. Still thrilled! Which is always great with a project when you’re happy years later!!
YOLOfotos well done...i m happy for you...but i m not gonna do that to my C2S...just don’t have the guts...👌
love this im doing it to my dads car and doing fabspeed headers aswell
Thanks!! The combination of the plenum, tune, free flow cats and headers was the best decision ever.
Damn you sir r brave. Was thinking about doing the same for my .2, but don’t think I’ll be doing that after watching this LOL. Subscribed tho!
Yeah, I too will pay a mechanic for this.
Thanks!
Great video. Subscribed.
Thank you!
Got to hand it to you YOLO ambitious project and not one curse word. At least on camera.
ksheeh Lol. Yes, not on camera at least. Several panic moments. Thank you.
That reservoir with the green-black cap that sits atop a pump that you referred to the power steering pump is actually the PDCC, the Porsche Dynamic Chassis Control. The power steering in this car is electrical.
A Christian thanks! Had no idea!!
i hope this was worth of trouble. i am taking to shop...great work and patient...
Woojae Chong thanks. The outcome of all the work, plenum tune exhaust was all totally worth it!!
Great job.. Thanks for the video and making our life easier. I have a question, are there any special tools you used to install the IPD, am thinking of installing it in my 991 Coupe and want to make sure I have all the right tools.
No nothing specialized that I can think of. The hardest part is getting the rings on the plenum and intake manifolds. But still no special tools were needed. Thanks for the comment!
Impressive
iluvcakes19 thank you! By far the most involved project so far.
Really good video! After an AOS replacement (it was super oily) I ended up following your tips on reinstalling the plenum, it went it fairly easily after that and having fumbled it a few times prior. Thanks! Also, I too like to clean-up as I go along and you mentioned giving it a light wash once it mostly assembled, any troubles in doing this? Any specific components to avoid getting water on directly aside from the obvious ones like intake and alternator?
I have a video in this playlist, washing your 911 motor. And thank you! Glad it helped!
Well done. Def not a job I would have undertaken. Besides the Fabspeed headers is the rest of the exhaust stock? I was considering the Fabspeed catless race headers, IDP, air filters and COBB tune.
Allan Kozich thank you. There were a few oh crap moments for sure. I did fabspeed headers with free flow cats, the car has stock sport exhaust with valves. K&N filters, however I’d do BMC when I replace them. Less oil- better filtration I’ve read. Also did the Cobb 93 octane tune but then bought the fabspeed tune after I did the headers cats and plenum. Fabspeed will have you send them data logs after the mods and write a tune just for you. It made a huge difference. I was really surprised. Also the sound is incredible with the stock sport exhaust and the free flow cats and five. Also also the sound is incredible with the mods. There’s nothing else to do to this motor. Very satisfying. I did a video on the headers and the tune. please check it out.
I watched all your install videos and what you have done is exactly what I will do. I'm going with the Girodisc rotor upgrade first, suspension 2nd and finally exhaust/intake. I had catless headers on a 2005 M3 and it made a huge difference so I'm considering the catless race headers. I track my GTS so the suspension needs to be addressed as the front spring rates are too soft.
Allan Kozich nice! I want this rotors next. I was just looking at them this morning. I’ll wait for fabspeeds Black Friday deal. They are usually pretty generous at 15% off. If you video the install I’d love to see it. What pads are you going with?
Contact Apex Performance and speak with Clark. The front rotors will be the model where I can use the GT3 size brake pad and the rear will use the stock size brake pads. I'm going to try the Ferodo DS2500 as they are between the stock Porsche pads and a race compound.
Hi Yolo! Awesome video. Really gave me some valuable intel! One question, could you have accessed that air flow sensor that was on top of that plenum without removing that plenum?
If that sensor goes bad that’s a major task getting to that sensor. Thanks for letting us know about getting yo that sensor. Great job!
991 911S once you got to it, you would only need a small ratchet to remove the screws from the sensor and if my memory serves me I do believe you can pull it up and out without lowering the motor. Worst case scenario you would have to lower the motor which really isn’t difficult. Thanks for the comment!
YOLOfotos thanks Yolo...appreciate your input. I have to say, I would have quit your project when I found out I would have to lower motor. Nice job & Congrats on your persistence.
YOLOfotos Hi Yolo, thanks for your help. Yes, small ratchet & torx30 was answer. Porsche gave us a break! Lol
@@user-qy5mq7lb8p BOB, i just got the plenum, my son works BMW shops, so I hope he will help me do the job of install. My question to you is if you did it again...how long would it take you? or should i just take it to a shop to do.
It would take 3 hours likely. Most of the time is dismantling and reassembly. If there’s oil in it consider replacing that oil collector in the back right side. Good luck!
Great video! I have a 997.1 + Fabspeed exhaust & headers, BMC cold air. I'm thinking of the IPD plenum & GT3 T Body. Think the install on my car will be a bit easier. My problem is I am stuck with the stock Cats - CA car, not legal to switch them out. Do you think this will seriously limit the benefit of better plenum/T body?
John Kingery how would they know? I believe even with the fabspeed cats the emissions is still low enough. Anyway, more air in more power, more out more power, so either way you’ll gain. Also, consider the tune. You could have the performance tube for every day and put the low emissions sucky power tune in for test day...
@@bobbygfl That's a possibility I have considered. Probably the next project will be the plenum + throttle body. Your video on header install was also v helpful. It was very similar to my 997, much more so than the plenum I think.
Nice video I am in WPB have a 911.1 t4s. Does the power kit make a difference over not having it?
The power kit ads 30 hp I think. The big difference is the tune that I did from Cobb is significantly better with a power kit car. Mid RPM torque is incredible.
Wow! That's a lot of work man! Did it add some Horsepower on your upgrade? It does sound good than the stock
TonyJames Bautista it did add power. I’d say responsiveness over just HP, but I’m not a mechanic. It was a to of work lol. Thanks for the comment.
I have so many questions. Is the aftermarket plenum more for sound, or low-end torque, or just more power in general? All of the above? Haha!! You mentioned low end-torque at the beginning of the video. Do you mean between 1000-2000 rpm? 2000-3000? Thanks!
Snap Happy Photography Every RPM range has been impacted. From a standstill it is noticeably more powerful. At about 30 miles an hour if you punch it it really takes off. At about 70 miles an hour if you downshift and floor it it’s ridiculous. Remember though my results are the combination of headers Plenum and tune.
Hi! Great video! I was looking for a DIY on Workshop Manual WM-100109 which is where instructions are. You method kind of differs. Would you be nice and tell me from this experience if you just supported the engine with the jack and completely removed the 2 mounting bolts? I mean, you didnt have to lower the jack again for extra clearance right?
On the advice of a Porsche mechanic that I mentioned during the video I did completely remove the bolts while the jack was supporting the engine. I then used the Jack to slowly lowered the motor until part of the transmission rests on a cross bracket not allowing the engine to drop any further. It’s very obvious and there are no hoses or electrical wires that you could damage in the way. I then lifted the engine maybe a quarter inch to take the pressure off the cross bracket (I really think this just made me feel better pretty sure a mechanic would just let it rest there) and then tightened up the jack in that position. Hope that helps.
Incidentally you may be interested in returning the motor to its original position. Because the car is sitting on the race ramps it is actually sitting on its suspension. I jacked the motor back up until it took about 2 inches of pressure off of the suspension. Again this is very obvious you can see the motor mounts seated against the frame. I then tightened the bolts to the appropriate spec. I can’t remember this torque but I think I mentioned it during the video. Anyway after I drove the car for about 30 miles I rechecked the torque. I’ve had zero issues since
@@bobbygfl hi man, thank you very much for taking the time to respond. You videos are very very detailed! Definitely will help me a lot! I am watching your previous and subsequent videos on the upgrades you made to your 991.1, pure gold! All the best.
@@redzone5655 thank you! Planning a 50 things to do to your 911 video pretty soon. I just got a new black lights and I’d like to get them installed before I do the video.
I probably fast forwarded when you explained. The OEM plenum has no internal flap? Is that right? If yes, what's moving the flap on the aftermarket plenum?
Snap Happy Photography they both have a flap. It’s controlled by a servo in the back of the Plenum. Watch the Plenum install video you’ll see the mechanical connection. I believe the flap serves for low RPM vacuum. At higher rpm. it’s wide open either way. I’m not a mechanic so I may not be entirely accurate with that. Another advantage is the aluminum Plenum disperses heat faster and helps keep the air cooler going into the motor. On a cooler day it’s very noticeable. The car is definitely more responsive now on cooler days but either way it made a big difference overall.
Great job...did you see any benefit with this IDP ?
Chauncey Leagones hi. Yes. Fortunately I did each mod one at a time over several months, so I had time between to drive and determine gain. Ultimately the tune/plenum/sport cat headers package adds up to the most change. The plenum alone added low end torque and increased throttle response mainly. The rpms are snappy. The car wants to jump when taping the pedal. If it makes sense, the car has more throttle attitude. Also I believe you can hear the intake air through the aluminum better than through the plastic. It adds to the mechanical sound of the engine. Hope that helps! Thanks for the view.
I think you had a great deal of stamina and perseverance to see it through. As a 991 S owner, I think about these mods, but then I think about the warranty if something goes wrong. My car is good until Sept '19. I think this is an insane amount of work to install a device that gives minimal improvement in performance (albeit the sound), but if you put all the mods together with a ECU tune, then what's the overall gain from stock hp and torque?
Ian D 400 stock. Dyno was 498 high 490 low. But this car has most of the x51 upgrade. The cams are the only mod I was unable to video. And the tuned intake manifold is the only x51 mod I did not complete. It’s a significant feeling change between 3k and 6k rpm in lower gears. The torque in the higher range after about 100mph in 4-5-6 gears from 6k to 7500/8k is crazy. I think it’s more powerful than a gt3 at least in the way it pulls. Just me. I wanted the project mainly, but couldn’t find a gt3 touring in my budget. Plus even the touring doesn’t have back seats which I wanted. I’m also not crazy about the gt3 front. Too much info, I know. Lol. Anyway thanks for the comment. I was able to this much power on a reasonable spend. Way under gt3 prices. Also I don’t like alcantara. Lol. Also I waited for my warranty to expire before I began the mods. The two years of warranty I had, I used that time to plan what I would do.
YOLOfotos I would like to chat. I’ve got a decision to make and would like to hear your thoughts.
Ian D sure. Email me your contact info. bobby@yolofotos.com
Great job!!! Will you do a cold air intake swap? If so which brand?
Tom Curry thanks! I will not do a cold air intake. I’ve done enough research to convince me that they are useless. The car’s design does not force enough cool air through the engine compartment and the reverse actually occurs where are you were sucking in hotter air then with the stock intake.
YOLOfotos that's what I found out also lady night doing research. Claims don't match up to dyno tests. Considering this swap and maybe headers. Agree?? I have a Soul Performance Exhaust and I love it. Thanks for the quick response 👍
Tom Curry thanks for the view and the dialogue! For me the combination of plenum, headers, specifically the free flow cats, and the tune written specifically for the car (fabspeed wrote it twice to tweak out some extra torque) was an awesome change in performance. Not only sound, which is amazing. The car is punchy and very responsive. Low gear taps throw your head back. Entrance ramp acceleration is thrilling and passing at about 60 is unreal. The car just launches. I’d do the same mods all over. There’s nothing more to do the engine as far as I’m concerned and that’s really quite satisfying.
YOLOfotos ok I'm sold!!! Thanks and keep up the great videos. I love the variety of videos you offer also 👍
Wow. Congrats on getting the job done. Would you do it again? What would you do differently? Thanks for sharing.
Ah. I commented after watching 1 hr 14 minutes. Had I only waited a few more minutes...
John ha, thanks. It is a long video. Tried to be thorough!!
Was that a big crack at the firewall at around the 40 min mark? (After you've removed the old plenum.) That looks like a crack that goes all the way from left to right, above the un-utilized cable routing spot.
What you’re looking at is the foam sound and heat insulation which is falling slightly along the front edge. It’s about a half inch thick. Not enough to do anything about it, but it does create an uneven line, which is what you’re seeing.
@@bobbygfl Thanks! I was trying to see if it was something like that, but the video just makes it look like a horrible crack. "I know his video is about the plenum, but why's he not addressing this crack?!"
lol! Oh if notice that for sure.
Well done! Braver man than I and how was your back afterwards? ;)
Darren Yates ha! Thank you. And sore! Actually replacing the air oil separator was more of a backbreaker because it’s deeper into the motor. Thanks for the comment!!
Your welcome dude!
How is IPD Plenum with Fabspeed tune? I have 2016 911 Carrera and so far I have installed BMC filters, Fabspeed X-Pipe to remove center muffler and I removed side mufflers as well. Car is loud AF even in regular mode. I have IPD Plenum and Fabspeed tune to go next, but wondering if I should install Plenum or not. Thoughts?
It’s hard to say what difference just the plenum makes. Sounds like you did what I did, increase the airflow in and decrease the resistance out. I can say the combo of the plenum, tune, headers and cats made a significant difference. Also, you know how you get more power when it’s cold out. I feel like the aluminum plenum causes this because the aluminum disburses heat better than plastic. Anyway, you can’t go wrong doing it. Hope that helps.
@@bobbygfl Thank you for your reply. I installed Plenum yesterday and drove about 100miles for ECU to relearn. Downloaded ECU read file and sent it to Fabspeed for a tune. Wondering if I should get Fabspeed headers or not as with center and side mufflers deleted car is already loud. Did you remove side mufflers as well?
@@acidburntx9257 I did not remove them. I have the original side mufflers and the original center muffler and original X pipe with original valves. The only thing I did to the exhaust was a five speed header and free flow Fabspeed catalytic converter‘s. I did not want a loud sound. I wanted it to be throaty but when I had the exhaust valves closed I wanted it to sound stock quiet. I’m not sure what the headers would do for you but the free flow cats made a big difference.
Hey, at 14:35, those solenoids that you pointed to that could go bad, what are they exactly and how would we, 991.1 owners, know if they’ve gone bad? Just want to put this into my toolbox for the future. My 2015 991.1 has only 19,000km so I’m assuming they should be good for a while yet. Thanks!
Capital Exotics I did a bunch of research on those. Porsche had a recall on them early in 2014 I think and said if on failed replace all. I think there are 5. Some owners have never had a failure. You’ll know because you’ll get a failure warning on something they control. First check should be the solenoid. By 2015 they got them right I believe.
YOLOfotos thanks for the info!!!
I'm sorry but I don't understand much English! What piece do you change the plastic bag with the Porsche seal and why do you change it?
i'm sorry i do not understand what you asking.
It was the air oil separator. He changed it because he had a lot of oil in the plenum, a sign of a failing air oil separator.
Great sound and I imagine it’s way better in reality since your mic is acting out a bit under throttle.
Panzer966 thanks! Love the sound of this motor!
I have a 2015 GTS cab. And I’m looking into different headers, in your opinion does this header stay true to the Original Porsche sound, just louder ?
Panzer966 yes. It’s slightly deeper. There is no mistaking it is a 911. I’d say when you first start up your car in sport mode and it idles slightly high and sound so good for that first couple minutes- it sounds like that all the time. A nice rumble. I really need to set up a better mic and record it. And the crackling when your exhaust is in sport mode is crazy cool. When your exhaust is open and you are hard on the pedal it sounds like one of the 911 race cars. But that’s only under full throttle. My favorite thing about this one is when the exhaust is closed it sounds quite. Like stock w no pse. Best of both worlds in my book.
Is this for a 991.1 carrera ? My car doesn’t have actuator on the back side of the car to go to plenum
It’s for the carrera s. Perhaps the non s engine does not have that.
Did you disconnect or loseen anything else, besides the mounts? Wondering if there are any hard lines that might snap with the shift of the engine.
Andres Tavera no. Everything is attached to the transmission and the whole thing just swivels downward. I’m told that the transmission can rest on the cross brace however I did not do that I just lowered it to the cross brace. The threads on the engine mount bolts are very fine so it is a lot of turns to get it to drive about 2 inches. Have it braced with a jack because once you’re out of threads it will drop.
@@bobbygfl Great, thanks for the info! Did you measure prior to lowering the engine so you could put it precisely in the position it was in?
Andres Tavera no. There’s no need to. The nuts bottom out on the body underside of the mounts. The torque was huge. I can’t remember, 90 pound maybe. Anyway it only goes back up one way. I checked them after a few weeks but the didn’t budge.
Nice, you put my fears to rest. I will be replacing my air oil separator soon and while I'm in there I will be switching to an aftermarket plenum.
Andres Tavera awesome! This was a great project. Learned a lot about where everything is under there. That oil separator Will be much easier to replace once the motor is lowered. Check out my channel I did a video on just the oil separator replacement
My 991s with sport exhaust has great sound and very responsive in sport mode. Lots of burbles and popping sounds. I don't think I could use any more power. It spins the wheels on hard acceleration from around 30 to 40mph if you step on it hard. My S4 is tuned for about 475hp but that was easy to do with about 2 days labour. Hardly any engine work involved, just software.
It is with pdk so it downshift quickly.
paul l sound like you’re happy with it! That’s great.
Where could I buy that piece.? Thank you
You can get it from www.fabspeed.com/
How much easier would this be in a coupe?
No idea. Likely easier.
Hello which air filter do you recommend? Thank you
I use K&N but if I ever replaced them I’d go with BMC. There’s a couple reasons. All just my opinion, I have no proof which is better. 1. The rubber used around the filter element appears to be softer and of a better quality seemingly would get a better seal. 2. The filter element material appears to be more fibrous. It seems like it would hold back dirt better. 3. BMC seems to be a smaller company and I just believe quality control would be more important to them. Anyway hope that helps
@@bobbygfl Hello you could give me an opinion of this czcams.com/video/w7G-co5SJ0o/video.html
@@3manresa generally my opinion of these is they don’t actually do anything. This one does seem like a clever design however you’re still pulling the air in from exactly the same spot. Clearly the filtration surface area is increased. I really don’t know if that means more air or just more filtering longevity. I would almost guarantee that it would sound better. Seems you would be able to hear the intake suction and mechanical sounds from the intake side of the engine. As far as performance I’m sure it’s just like anything else, maybe you’ll get a horsepower or two but combined with doing several modifications you net out a noticeable game. Thanks for sending the link I’ve never seen this product. As far as getting cooler air into the engine I don’t see how that would even be possible considering the air is coming from exactly the same place.
@@bobbygfl thanks a lot
Now that I have watched it all, what a job for a debatable gain. Really, if you are talking "mods" and "tunes", the only way to know for sure if you made any HP gains is by using a dyno before and after each mod or tune. Otherwise, you are just guessing.
BTW don't tell me someone on Rennlist talked you into this. The 991 crowd there really isn't that informed. Most of them are just drivers and like to talk a lot.
A Christian thanks for watching! Car dyno’s at 498! I’m thrilled with the power from the stock listed 430. That said, I wasn’t after HP. I was after attitude. Stay with me here. I love the snappy air cooled cars. Each one feels a bit different. Even the same car in different weather seems like a completely different car. I loved that. Got in a 991 and it felt underwhelming. No attitude. Nothing unpredictable. Got in a gt3. Loved the punchyness, hated the rattling. So, I did a bunch of research and decided a 991 3.8 and the mods I did. Exhaust, cams, plenum, tune. What I’ve ended up with is a punchy car full of personality. I’m really thrilled. Doing most of it myself was a lot of fun to! Thanks again for the comment.
@@bobbygfl I'd think the cams and computer tuning probably did the most. The plenum and exhaust probably the least. A 68 HP gain? Are we talking at the crank or at the back wheels? I think the 430 HP of the GTS is at the crank.
A Christian probably at the crank, I really don’t remember. Its been a year since I had it done. I’d never dyno it again. 1, I don’t care and 2, i think it’s a violent process. Seems like a lot of opportunity for something to go wrong. Moved on to adding more leather to the interior!
Opps spoke to soon
Lol
so ipd is smarter than porsche engineers? could you notice an improvement? be honest :)
I think I might post a video on this because this is the number one question I get. The performance increase is the combination of the headers the Plenum and the tune. I noticed the biggest difference from the tune. The feel of the car has completely changed. It is much more powerful in the mid range and feels very similar to a GT3. The power increase is between I’d say 2500 and 4000 RPMs. As far as and unexpected improvement the aluminum Plenum helps improve the sound of the engine in my opinion. You can hear the top end intake sounds more clearly it makes the car sound more mechanical.
Porsche are the most difficult cars in the world to work on!
recon forsales ha, sure felt like it. Thanks for the comment
IPD lol
Demar Gio thanks
Do not rev the damn motor when it’s cold !!
Arnold Mosk great tip! Thanks so much.
when exactly did he rev the motor when it was cold?
You should have sprayed the MAF SENSOR TO CLEAN IT
Thanks! I don’t actually know what that is
Barefoot? Really?
