Drink every time Paul says "Pulley."
Instructions unclear, I died.
Pretty much wasted @ 01:31 😂😄
2 years later, I am just now recovered
Thank you so very much for doing all of these videos. You definitely don't get enough views for the work you're putting in here. I bought my B8.5 S4 last year and am finally starting to look into beginning a journey into modifying things now that its over 100k old.
How did the car hold up
MRC in the UK have been doing crank single pulley for a few years with great results, many of their customers vehicles are dyno'd at 490-500ps
Awesome video! Well done gentleman! That thing is quick!
Another fantastic video Paul!!! 👍
Crazy stage 3 already not even a year later. Im about 3 months in on my B8 S4 and at stage 1. Before i purchased the car knowing DAP content was out there made me feel more comfortable knowing i could do all or most of the work myself. I have weekly videos on the S4, hoping to teach a bit and learn alot. Thanks again for all the great content.
The King Of Lions I’m thinking of going straight to two or three any advice, but I’v had trans. Issues but it’s not the cts transmission so I think I’m good ? What do you think from your experience?
Good to know always loved audi in terms of cost big bang for your buck in upgrades also like the fact that the 3.0t comes in many of there vehicles I'm going straight to 3
when reinstalling the acc belt, you can actually unscrew the "silver" idler pulley a little bit in order to get the belt through the slot... :)
Now it’s time for APR ultra charger kit!! Stage 3+
Another great install video, Paul. Thank you for sharing!
your stage 2 DSG tune is a game changer.
@@jacobhauenstein Thank you for your feedback!
Lads, do you have a dealer in Ukraine?
@@aishchenko Unfortunately, we do not. Feel free to check out our dealer locator www.getunitronic.com/locate-a-dealer and look for nearby countries that could help you get your hands on Unitronic products! You can also send us an email to info@getunitronic.com and one of our Sales Representatives will help you.
Thanks for the detail.
Just want to be sure that these numbers were achieved by only doing the double pulley system, flashing of the electronics on the engine management and auto box? No exhaust changes and or intake changes to pull more air into the supercharger?
I wish they had a dual pulley for my 2014 Q7.
Only at stage 2 single pulley APR. let me know, I’ll stop by your shop.
HELL YEAH BOIIIIIIEEEEE, GET THAT
Hey bro great video. Do you need a trans tune as well??
I have 2012 A7 Audi and was thinking of the tune. Just upper. Because if I do lower I’m into all kinds of headaches???
Any thoughts people!!!
Just a side note if you've got a 6mt you will need an uprated clutch
Thanks.
Good morning DAP what can I do about a cut frame? Previous owner made the car a stanced car with air bags. A4B7
Are you going to do anything for the heat soaking issue? Also are you going to upgrade the throttle body for more hp?
Nice
How did you know what size of belt you need ? For example i go with Forge 57.2mm, how you calculate the new bigger one crankshaft pulley and the belt to fit in the smaller SC pulley ?
I don't see it written or mentioned in the video, but the Unitronic crank pulley is 187mm, the supercharger pulley is 57.5 mm, gives you a ratio of 3.2517.
Quidproquo07093 just saw this comment after I wrote a reply above. I’m with you on this one... “Stage 3”?fishy ain’t it?
Can you install this stage 3 unitronic and APR Ultracharger Throttle-body upgrade? Or would there be ECU Software issues?
Any plans for upgraded cooling? You’ll be heatsoaked before you get out of 3rd on stock setup
I have been asking the same thing. I hope he address that issue so we can learn how to upgrade our cooling system.
There are kits out there but they cost an absolute fortune. You're looking at £2k plus.
034 has the heat exchanger kit for 1k USD
@@TheCrazySquirell Check out merc racing heat exchanger! $400 for the kit
@@robertogarcia9413 CCheck out merc racing heat exchanger its $400, its for b8.5 and m3 im pretty sure
Lower pulley looked to be the same size as the stock. Is it suppose to be that way?
Are you running the off the shelf standard stage 3 tune or their race tune
crazy question. Is it possible to change the supercharger for a turbo in this model? How much it will cost, aprox? It will affect de reliablity of the engine and what gains in performance we will see?
Question ... if the belt snaps down the road or you simply want to replace it one day for preventive maintenance, you have to unbolt the crank pulley again to replace it?
I would love to see the Alpha Performance Heat Exchanger upgrade video on this car. Includes Bigger heat exchanger, additional reservoir and Pump. A completely upgraded system.
BK Shaw is their kit necessary though? Just a mercracing cooler and a pump modification seems to keep the IAT’s very low.
@@jacobhauenstein I'm looking at the merc racing heat exchanger, how efficient is it compared to the APR, REVO, Alpha or forge motorsport ones, also I definitely want the uprated pump, but can you use any uprated pump for this? Do you have a link for a good pump to work with the merc racing heat exchanger?
@@TheCinderellaman10 I haven't seen any scientific tests, but I know that the Merc is easily as good as the APR CPS. The only one that might be better is the Alpha one, but not because the heat exchanger itself is better, just because it comes with many extras and a reservoir. The whole purpose is to keep IAT's down, and the merc does. Also, I cannot think of the pump upgrade off the top of my head but there is an audizine forum explaining it. It's not a major upgrade, and right now most tunes will make your stock pump run at 100% to flow as much as possible. In my tune it goes to full duty cycle any time you are over 2000rpm. You can use any pump that will communicate with the car, you dont need a specific pump for merc that doesnt work on others, all the HX's work the same. Spending more than 700$ on one doesnt make sense to me though: you could get the merc, and do a water methanol injection setup and have results better than a 2000$ standalone kit. Or, if you are being convinced to buy the Alpha kit which is really $$$, you could buy a Killer Chiller and have below ambient temps.
@@jacobhauenstein I personally wouldn't spend £2k plus on the Alpha, it's a great piece of kit but like you said others can do a good job and save money to put into other supporting mods, the merc racing heat exchanger is only around £500 in uk from a place in Scotland and I'm sure they can acquire the pump and reservoir also. I would be saving around £1k compared to Alpha and APR. Btw did you cut the wire from the pump for it to run in emergency mode at 100% or was it programmed into your tune?
@@TheCinderellaman10 That part was programed into the tune. I know Unitronic does it, and I believe APR does it as well.
What kind of wheels are on that TT in the background?
This is a great tutorial, as all of your videos. Unfortunately I am not for the non harmonic style pulley setups. The rubber is there for a reason.
So you have to take the crank pulley off every time the serpentine belt needs replaced? IE dual pulley kit isn’t like that.
Hi, Can manual gearbox and sport diff take it? Running for years at Stage 1 and 417hp.
What do you recommend for the V3
Is this on the stock dl501 transmission? What can the trans safely take?
Do you have a vid for brake upgrade?
Can I do this for my 2015 Q7 S line??
What’s the total cost on all the upgrades to get it to stage 3
Integrated engineering says that you only need this pulley installation… not both pulleys. on their website it says there are two different crank pulleys? can u help me
Does the 2017 s4 have launch control
What would be the downsides of a setup like this? What is the compromise in terms of reliability other than the increased supercharger pressure? Also, have you noticed any change in fuel consumption after the upgrade and the tune?
catalytic converters tend to go at this power level, other than that not much else can go wrong
@@wangshuokevin I wouldn't say that, it is going to add more stress overall. The odds are leaning out of your favor the more power you extract. That being said; I've been at stage 3 for a year and a drive hard, not abusing it, just hard. Runs perfect and my oil analysis is spot on every time.
Only a few have had their cats go, best to keep an eye on the extra back pressure and go for high flow cats or even a catless downpipes but then will fail emissions test at MOT so for me hfc
My friend has an S5 with this motor. I have a 335i n54 BMW I'm trying to get rid of. Along with the V10 s6 that's down right now but I'm looking to get an S4 with this motor is there a way that somehow we could be in contact because I have some questions
Can you go from an un-tuned car straight to stage 3? Seems like you'll save time if you install both pulleys at once and flash it once.
Yup. We just wanted to show each options which is why we did in stages
Yes, you can go from stock to dual pulley with the ECU flash. Also recommended is the transmission flash - check out their website.
What's a "triple square " ???
Is it Murican for "hex", by any chance ?
Does this pulley go over the standard pulley ? Your video is not clear about this.
Well this set up work on a regular a7??
Hi. I have a CTS Turbo crank pulley id like to install but seriously doubt I can pull off the install. Curious if I were to bring you my car; do you offer Dyno tune also?
Our shop can take care of the install for you. Check them out here www.daprepair.com/. Sorry but we dont have a dyno
Where i can get that 0-60 counter 🙏
Would it be worth it going stage 3 on a SQ7 TFSI?
👍
Is that downhill?
Can anyone answer my question: been told not to modify my Audi A7 3.0T supercharged engine 2014 since the “timing is difficult to tune”. My initial thoughts are that the mechanic is not confident to carry out the work: any thoughts 🤔🤔🤔 I would really appreciate your comments!!!
I'm stage 2 unitronic on my 2014 A6 3.0 i cant see whay your wouldnt be able to do the same... works mint
I have some questions concerning cost & software stability. The tuning flashes & upgrades are also applicable to my 12 S5. I will be considering these upgrades after my bumper to bumper expires. I will be studying your progress on preparation & I would do both the pullies at the same time, but that's just me.
I got stage 1 tune can I jump str888 to stage 3
I’m stage 2+ in my 2011 B8 S4 Heard it’s not worth the stage 3 due to gas consumption and very hard on the engine? Thoughts/advice? Is the TCU stage 2 DSG install next?
I have a DP setup on my 2013 S4 (tuned by EPL). I upgraded two years ago, and have not had any fuel consumption increase under normal driving conditions. Nor does the engine feel stressed under hard acceleration. Only downside is heatsoak in the supercharger in the summer due to extreme heat caused by overreving the SC.
I have the DP on B8.5 (2013) S4 - haven't noticed any different in fuel economy other than more spirited driving = more fuel. I also did the larger heat EX, no reliability problems, nor have I read about any on the forums.
Wait, so the ancillary drive belt is captive now? So to change the serpentine belt you have to pull the pulley off entirely? That's annoying :(
Some other comment here said you can loosen the tensioner instead. Came to comments for same reason. Should probably replace belt at the same time
Heard from other sites vibration and balance problems when switching from OEM pulley?
Can someone give some feedback?
That came to mind when they mentioned no dampening on the crankshaft pulley. those can be destructive vibrations & Audi had put considerable research in prevention.
I would like to put a 3 liter supercharger on a 2001 A4.I'm wondering if I would be time ahead to get an after-market pulley like the one you show here in the video. I'm also wondering if you make kits that adapt the 3.0 supercharger pully system to my 2.8. I'm just beginning my research to see if I can make this happen. Any info anybody has would be greatly appreciated.
Haha this is some high end trolling but no one fell for it
You should get the 6 liter sc kit on the a4 because the pulley will get more power out of the 2001 a4 and it will get even lower consumption because the sc will be working less harder for the same result so in the end it does not matter if you take an tune or not
Is a tune mandatory or can I just run with a single smaller pulley and push more power??
Pulley without tune won’t do anything as the vehicle will open the bypass to adjust for the added boost
137k miles or K on the odo?
This kit fits the b8.5 SQ5 too, right? I assume so
Jordan Wilbanks SQ5, A7, any of the 3.0 TFSI of that generation I believe
3.34s - 0-100km??
Dyno time? :D
So the dual pully runs a separate belt for the supercharger?
It uses the same belt. :)
Someone already mentioned cooling... What about stock cats? Will there be a DIY on changing those to an aftermarket brand? (Is unitronic tuned to not overheat the cats?)
Stanley Suber thats exactly what I was going to ask. I’ve read a lot of forums talking about whether the DP setup melts the stock cats. That is whats keeping me from upgrading from Stage 2 single pulley to DP.
@@josuevelez3500 there are two videos on CZcams with partial explanations, one a guy cut his because he couldn't get the cat out and one where a guy straps the trans to the left and says there is room. No videos of someone actually doing the swap.
Josue Velez I’ve been running stage 2 single pulley with the stock DP. It’s totally fine. The problem is when you start to run Dual pulley is when it gets a bit to hot. I avoided going dual pulley because I have a FluidDamper and it’s a bit to fat to add the extra pulley. Anyway I hope this helps. Just remember to change the lower pulley at around 50k mi anyway because you don’t want it to fail!!! And I absolutely love the stage 2 single pulley there are not many cars that can keep up off the line!
@@scalways thanks, I'll be going single pulley in a few months and get that trans mount also. Not many cars are in the 3s for 0-60.
@@jayboom10 nice! Jusy be sure to address cooling!
Is that to wheels or crank
Sean Clark crank
how is this stage 3? i thought stage 2 was crank pulley, supercharger pulley and tune.
Stage 2+ (we don't have a Stage 2 per se) only uses the Supercharger Pulley Upgrade where our Stage 3 uses both the SC Pulley and Crank Pulley.
Cheers,
Don't these cars turn into unreliable messes with anything more than a stage 1? o.0
Paul! - i have a HUGE PROBLEM !!! I own the 2017 GTI Clubsport MK7 bought from factory with the Halogen lights. I want to get either Helix LEDs for MK 7.5 to fit into my MK 7.0 GTI Clubsport. VW say they cant do it, would cost a fortune. Iv asked two of the biggest car part dealers in germany online, they checked my VINS (Chassis Number) Even they said the Hella OEMs dont fit my car because diffrent OEM numbers... Is it possible to get this to work for my MK 7.5 Clubsport 7.0? IF it works? What exactly do i need more than the Headlights itself, for a proper installation? 🤔
I ve heard this stage 3 dual pulley destroys the Catalytic Converter....true? thoughts? fixes?
Yep. Heard you have to go catless. Looking to confirm.
@@CZcamsHandlesAreStupid Darn. Let me know what you are able to confirm. Thanks 🙏
I mean I can’t confirm from first hand experience yet (hopefully later this month) but from everything I’ve heard and seen (I’m absolutely obsessed with the b8.5 and have been watching videos since 2014) you absolutely need to remove the cats/go straight piped. The cats cannot handle more than stage 1, maybe 2, and even that is welcoming disaster. Better to just get downpipes/full exhaust done and then full send with stage iii and upgraded blower/throttle body
@@HuheJass Appreciate the response. What if its a c7 A6?
@@marksimpson4377 I’m gonna go with yes, unfortunately. I’m assuming you live in a state that requires emission testing, if that is the case it’s going to be Very hard to go stage iii and still be legal. You could go stage ii and replace the cat if it fails before inspection but that could get expensive fast
Feeling pretty torn between a b9 or modded 8.5.
B9 S4's are gonna be so much better for modding... ONCE they crack the ECU on those.
We are under the impression the B9 doesnt have a lot of room left for tuning, but that remains to be seen
Seems like the major players are having a hell of a time working with that ECU.
B9 doesn't get the dual clutch
I don't even own an S4 why I'm i here? 😂
Lmaooo same but I’m upgrading soon
Any crank pulley set for 2.0 tfsi Paul? 🤔😬
No as it would yield you nothing. 2.0 tfsi is a turbo car not supercharged. Exhaust vs belt driven from the crank.
LOL!
😂😂😂classic
dp with no cooling! are you mad
Heat exchanger especially with dual pulley is a must, would also alleviate back pressure with hfc's or catless downpipes, I would recommend getting the heat exchanger with pump and reservoir even with single pulley, they produce heat soak and personally dont want to be waiting for temps to lower all the time just to do another run
I don't want to worry you but there are stage 1 S4's with flex fuel e85 pushing more power tnah this, a friend of mine is pushing 504 with just a stage 1 on full e85, another one is pushing 523 with just a 189mm pulley on e85
Everyone has a friend.
Great video but you talk entirely too much! Less talk more work! Other than that, very informational.
You know damn well the crank pulley isn't stage 3.
It depends on the tune. Every tuner calls it something different. iE is dual pulley, APR is stage 2+. Unitronic is stage 3.
I thought the same thing! 😂
Jeff Cain I agree with you, if the SC Pulley is also Unitronic’s (and the new Crank pulley 187mm) they’re only spinning at a 3.2ish ratio, barely pushing the SC’s stock “efficiency” range at top RPMs... With upgraded cooling it is known you could go well past that Pulley(s) ratio.
Shame Unitronic for trying to claim “stage 3” when in reality this is just as other’s “Stage 2+”.
