- In this video, Craig Bimmer explains a modification that isn't often talked about in the BMW community and demonstrates installation. This mod is compatible with the following BMW Valvetronic engines: N51 N52 N55 S55 N20. MILVS add 1mm of intake valve lift when the Valvetronic system is in its max position. In this video, I demonstrate how to install MILVS on my 2006 BMW 325i.

This video is sick. There's not a ton of information online about building N52's since most prefer the N54. Glad I found this channel. It seems like only recently we are starting to really see the tuning potential for these engines and chassis.
Thanks man! That is true !
@@UltimateBimmerExperience Yup only a couple out there.. trying to get to Jayson level.. most of his engine was stock 😅 czcams.com/video/AO-eF5OA224/video.html
FYI: Kassel can up the redline for you as well.
Source - Jim tuned my ECU to accept an N52 in place of the N51. Coded for 3 stage manifold, 2ndary air pump out (only on N51) and threw in the higher redline at no added cost. Really happy with the results and service from Kassel.
Nice, that's good to know. I'm still wishing I went with them 😅
this is the upgrade that no one really talks about, it's interesting. It's quite a boost to this car.
Man, sick job! The red line looks scary but the sound is scarier!!!
Your and N52 is getting close to F1 sound.
Awesome video!!!
Great work explaining a lot I never understood on forums and when I asked I never got the clear and “right” way to do it. And documenting it clearly. I thought this was some unattainable mod. Much appreciated
Right? I had to really dig to find info on it, and it was intimidating. But I knew I just had to do it and find out. Thank you for watching, I'm glad I could help.
Great video! Good balance of humor while still showing and explaining exactly what needs to be done. I'm surprised you don't have more subscribers
Thank you so much !
Exactly this guy is soo funny
Hell yeah. So glad I found this channel. I’m trying to pickup an 06 330i 6mt next weekend so I’m already researching all the NA performance mods. Informative and funny 😂 milvs are the best
Thank you! You won't regret 🤘
THANK YOU for this video! Great overall explanation of the milvs, needed this
You're welcome! Glad I could help you, thank you for watching :)
Thanks for sharing! I am now very interested in getting my own MILV mod. I will be working with a tuner soon to develop a tune for the N52. I'll have to ask him about this to ensure we include it. Keep up the good work!
Any update?
This is gold material! Deserve more subs.
Thank you!
i NEEDED this video 😩
Love your vid.. I was learning and laughing at the same time!
Glad to hear, thanks for watching! 😎
Awesome video/tutorial! Ive been drifting e36s and e39s since 1999. After a 1jz swap on my old e39 and obd1 swapping my 99 M3 (bc back in the day it was easier to tune/turbo obd1 e-proms w/o EWS headaches) , I swore that I wont modify my e82 daily driver...until I stumbled on your videos. Since i gotta get in there to change out the DISA valve, i now have a 3stage manifold, this upgrade, and a tune happening after the holidays. Please keep the videos coming and Merry Christmas!
Thank you very much, glad I could help you. Thanks for watching, happy holidays!
Bro I can feel the nervousness and shakiness (not a stab) If I was doing the same and would be doing the same if I ever did a mod similar to this lol. Thanks for the video!
Hahaha, yeah I was a little nervous. This was my first time doing this installation and I wasn't sure what the consequences could be if I messed it up lol. Thanks for watching!
@@UltimateBimmerExperience Nah completely understandable! It's basically the meat and potatoes of the engine. How is that mod running now, are you still running it? Did you ever end up getting a different tune on it?
Yup, still running them although I am on a different tune now. 22RPD which is a far superior product to StageFP for a lot of reasons
You're the boss man.
Great video and very informative
Thank you!
cant wait for you to dyno this thing. so far ive done charcoal delete,silicone boot, k&n, muffler, resonator and (maybe secondary cats) delete. im also interested in getting 3 inch pipes
Thanks for the knowledge
You are correct about the engine hating gaskets! Lol
Loved the little jokes here and there, great video
Thank you! Glad you enjoyed
wow you hit 70 in 2nd? props man.
Love your channel!
Thank you! You're one of the OG's
@@UltimateBimmerExperience Thanks! The BMW E82 125i M Sport account is mine. Also on Instagram under the same name. Keep up the great videos and style of narration. Love this energy
Thank you so much man, it means a lot. I'll check it out in just a little bit :)
Nice video!
Thank you!
Crazy enough, I've been driving around my n55 with a shot valvetronic Servo motor for 3 years. Ironically it's insanely reliable even in a consistently "unreliable" state
Well in which case, I've heard that the throttle body will carry the slack when the valvetronic isn't working.
I have this on my N52B30. I only need to chip the ECU to get the most out of it. Great that you cover this overlooked upgrade!
Awesome, what tune are you thinking?
@@UltimateBimmerExperience I’m going to visit Mosselman Turbo (company name) here in the Netherlands. They have decades of experience tuning all types of BMW engines and will make a tailor made tune based on the setup of my car. I have both the intake and exhaust side fully upgraded and the MILVS. So something tailor made will need to be programmed to get the most out of all upgrades combined. Will post a video on my channel and dyno sheets once done. Aiming for 300hp.
@@BMWEiMSport what's it running at the moment?
@@sajakhtar852 No idea. I have never dyno-ed the car since I own it two years ago. I will be doing a pre-ECU tune run to see what the HP is now but planning that during various Covid lockdowns where I live proved difficult. Keep an eye on my channel for updates on this and for more videos of course.
I love MILVS
Nice, I knew what they were but didn't want to mess with undoing those springs. I know what I'm doing next time my valve cover comes off. It'll go nicely with the headers and n54 manifold that are already installed. My older stage fp tune redlined at 7700 rpm when I was trying the trumpet intake.
Super easy, nothing to worry about. And interesting, that makes me less nervous about my redline. Though I still don't know where the peak is 😅
Was the n54 intake mod difficult? Do you have a n52?
What are u getting 0-60?
Rad dude 💯👍
just got a 328i as my first car, all this looks intimidating but i might give it a go
You got it! Nothing too scary
Dammit boy! I wish my 128i was a stick, but I'm also a mechanic, and I have built many engines, as well as turbocharging them, so this shouldn't be so tough.
I ❤milvs t-shirts coming soon
Active autowerke tunes for milvs as well. I own both stage fp and active autowerke tunes my preference is active autowerke better customer service quicker responses great datalogging software as well I tuned with nic Nunez over there for running e30 mix of e85.
Sick, I wasn't aware they supported MILVS
Ok kids this is why having friends is important.
I like stagefp better, yes I think it's over priced BUT Bob at StageFP will update/change your tune when ever you'd like, no extra charge. Where as the other company charges
Nice 😎👍🏻
Thank you!
@@UltimateBimmerExperience great content buddy... A +++
You are a good mechanic 👍🏻
Did the car feel any faster to you after the MILVs install? I know they say it's 10hp extra but tbh I feel like if you were to do a blind test, most people wouldn't be able to tell a plus or minus 10 hp difference but I could be wrong. I just feel like paying for the MILVs and tunes for like 700-800 for 10 hp doesn't really seem worth it but I'd genuinely love to hear your thoughts. Love the vid :)
I'd say slightly, but it's more on the mid to top range. You're right it's a pretty expensive purchase, I wouldn't do it before an intake manifold or a good tune in general as those are both a better bang for buck. Thanks for your feedback!
Did you have to turn the engine for each milvs? After completing all milvs did you have to turn the engine again back to tdc? Did you just start the car after installing everything back?
Yes you have to rotate the engine to align the cam lobe for each cylinder. After I completed each cylinder I rotated the engine a bit more to make sure everything spun properly. Reassembled and started
do u know the exact thickness of the install washer? im reinstalling the milvs on my current engine to a used 80k one.
I'm in the same predicament lol. I threw mine out, I don't believe it matters too much. Just enough to get the old support out and put the new one in
Check out my two videos on the 125i and N52B30. Would be awesome to hear what you think of my car, engine and sound. Thanks man!!!
In the program Ista for BMW you hace the option for relearn the valvetronic sistem, is good option for tune? Already have a tune but is not special for Milvs
It will automatically relearn but to get full benefits you'll need a tune for the car to understand how to use the increased lift. At least on n52.
@@UltimateBimmerExperience thanks!👍
Niceeee
Thanks for watching !
I also can't find ANY headers for my N51, so I'm kinda screwed.
cool
"your car is leaking oil as we speak"😭😂
Try running e30 blend thats what i did with my 330i well mine was tuned to run e30!
No e85 gas stations within reasonable distance :(
Look at this dynograph!
Haha I think you're the first to acknowledge that joke 🤣
I’ve done the MILVs to my 328i and had it flashed. Now I wonder if I’m getting the full advantage of the mod? Also I heard somewhere that we need a catch can if we do this mod, any insight on that?
What tune? And no, I've never heard of that. It's a different system, so I wouldn't imagine it being necessary
Infinite rev.. like a bike, so gud.. with some catless headders woud be a beast..
Just wana ask about the shims, aparently they too increase revs on N52, what are those and where do those install? cant find anithing about it just ppl talking..
I have both on my car. Check out the channel. Just over a week old. Only thing not done is the tune to max out all my upgrades. Thanks for taking a look. More to come soon and will share a dyno print out before and after ECU tune.
Going full catless pretty soon. But the intake valve springs pivot on them, and they are underneath your valvecover.
The bolt with the line why does it need to be torqued if you only loosened it 5 times and then tightened it the same?
That's a good question, I suppose it might lose some of its tension after backing out a bit? But either way the car specs for the bolt to be torqued like that. If I remember correctly, they maybe only moved 1/8th of a turn to get them up to spec. I'm sure someone could have a better answer than me.
Thanks, another question can they tune for MILVs in addition to tuning for intake and muffler delete all in the same tune?
Muffler delete won't affect performance but yes, both companies provide options to support intake, exhaust and fueling
Do the tunes work with the n51 as well?
As far as I know, yes
i’m close to kassel i might need to use em for an issue i can’t figure out🤣
wish I saw this before fix my car
great video ,,, was it worth the cost ?
Thank you! Yes and no, if you've done all the easier ones, like 3 stage manifold etc and still want more than yes. Otherwise it's not as beneficial as others. Thanks for watching !
Did you notice the difference???? Is it worth it??
Where do I buy these? There’s a site called bmw milvs that is small and only uses PayPal. Seemed sketchy just wanted to make sure
Yup, that's the one. He's an independent company.
Well add this to the ever growing list of expensive things I want to do to my car.
How’d it feel according to the butt dyno?
Butt dyno was tough to decide because I was mainly daily driving my 335 during this time. It was noticable enough, but not crazy life-changing, but watching videos in hindsight really impressed me. The 0-60 clip is really impressive in my opinion, and I've still got mods to do. If you're considering it, do it as cost effective as possible, because while it is worth it if you're trying to push the limits on n52, it's not worth breaking the bank too hard. It's definitely a good one, but not as noticable as say switching to a 3 stage manifold from a single stage. Hope this helps!
@@UltimateBimmerExperience Super helpful! The 3 stage is definitely first on my list 👍
Yes, definitely do that before doing this and see if you still want more out of it
What size washers?
I'm not sure, but the kit includes the washer you need to install
wish I saw this before fixed my car
I feel 🙁
I can just do my own tune at a shop correct?
Yeah, you're not restricted to the 2 options I mentioned. If you can find someone who can tune for the additional lift, by all means
@@UltimateBimmerExperience nice. I wasn't sure if this mod was limited to a certain tune. Might be a great idea to tune at the same time I get headers.
Thanks
hey man I got a question for n51/n52s that's unrelated to MILVs but I see that you drive ur n52 pretty damn hard and even pushing it to the limits at 7.5k rpm and revving out the car a lot but have u ever seen any types of head gasket issues or engine blow outs on completely stock engines? and I'm only talking about wear and tear and engine abuse not dumbasses who just don't maintain the car at all. I've only ever heard or seen a few very rare engine problems where someone's n51 block had a tiny crack in it that would just piss oil everywhere and even that's like a 1 and a million with these cars and I've only ever heard of a hand full of head gaskets blowing out but that was mainly from the car over heating from a coolant hose blowout and the car couldn't turn itself off fast enough for how fast the guy was going. I'm mainly wondering because I have a 06 n52 with 190k miles now, I've done a shit ton of maintenance and replacing parts on it to the point that I'm well over 6k in the car and the car definitely has a lot of life in her and I'm gonna end up doing a lci conversion to the headlights, headers, and a 3 stage manifold but I used to drive the car hard as fuck hitting red line a lot and sitting at 6k rpms for a solid minute. but what would your take be on a chance my HG fails?
Just like you said, I wouldn't say it's impossible but personally I don't think I've ever heard about anyone blowing theirs from natural causes. I've read a lot from forums over the years, and I don't I've seen anyone talking about that really. I have seen accounts from people with 250k+ mile n52 and still haven't mentioned replacements of headgasket. It might be one of the only gaskets we don't have to worry about really at all lol
@@UltimateBimmerExperience thank you for a quick response and ur outlook on these engines. I just wanted to see if you've ever seen or heard any of these problems on the car, I've known that the head gaskets are extremely rare and these engines last a long ass time, but I never really asked anyone that knows more then me about them. I was really paranoid for a while about my head gasket because I was losing coolant every few weeks with no sign of a leak and I remembered a while ago I hit like 5k rpm and saw a cloud come out the exhaust, then when I opened up the coolant cap and started the car I actually smelt exhaust but there was no bubbling or coolant spilling out and at first, this all pointed me toward a small head gasket leak and I was a little upset about it and was even looking at Hondas lol because I was so annoyed at how much money I spent on the car in a year and a half I owned it. But then about a week ago it got real cold and a leak actually showed in the lower radiator hose. Now that I replaced the hose the exhaust smell was gone and all my coolant is good now. My take is that exhaust was coming up from the lil leak in the hose and the cloud that came out was probably just water. I'm not sure but after I changed the hose and changed the coolant I let the car sit for 10 mins without the coolant cap and everything seems good to me now. I even lost love for the car for a bit bc of it being a n52 engine but u actually brought my love back for them and now I'm gonna start redoing the car and finishing the things I wanted to do with it and shit man after looking at the market that seems like the cheaper option now
so how much hp does this add?
About 10hp to the upper range on n52
No dyno before and after ????
Not me personally, but the bimmerMilvs has dyno graphs
Might just take mine into a shop and get them grinder down probably be much cheaper....might be crazy and go 1.5-2mm hahaha
Its not as simple as it sounds. MILVs are already machined to reach max lift possible on the eccentric shaft
@@UltimateBimmerExperience Id put money that they was concervative to not destroy people engines....Regardless I can just get them grinder down 1 mm like you said looks about a that
@@johncooper306 not even that, the valvetronic motor runs out of gear teeth to grab. At least to my knowledge
yeah sounds like a machine shop could do this for 10 dollars per milf
random fact, the n51 and n52 can safely redline at 7500 rpm and the highest the n52 can go is 8200 technically though not very safe
do you use extra virgin oil for oil changes ? It looks so clean. Looks like she hasnt been touched. Whats her interval ?
I use only oem KY oil. Lol I used Castrol gold bottle 5w30 and try to change every 5k miles. But the engine shown here I had only owned for 15k miles, so I suppose I got kind of lucky with how the previous owner did oil maintenance. But I've since had to replace this engine due to my own negligent mistake. But I got by what the Manual recommended but change every 4-5k on my regular 3 series
brave man. leave the 3 series to the ladies and get u a 550/650i a BMW v8 is a whole different animal! I've had no major issues other then BMW soft rubber turned hard plastic gasket leaks.
my battery is in the trunk 😢
Good video but "vtec garbage" is hilarious for an n52 driver to say.
How old are u????
Really feeling my n52 and enjoying learning about these German engines but... Did this guy just call "VTEC" trash?!?!?!?! 🤷🏾♂️🤦🏾♂️
U remind me of rocketpowermowhawk except American lol
I'm 24 lol, I'm not familiar with rocketpoweredmowhawk
Love a hot Milv
We each have our preferences
Your tach is prolly off a few hundred rpm
I've since found my redline, it's 7500 lol
14:40 “More *toque* for the street”
They couldn’t even spell torque.
Lolol I didn't even notice that
They stay sold out…..
Yeah, they usually are lol
6 Milvs 😂
Mhd wouldn’t work?
I was speaking just on my options for n52. I'm not sure what tunes accommodate MILVs across other platforms or if they're as necessary. I hope to try this on my n55 sometime in the future.
