Thanks so much for your content. I learn so much about my B8.5 S4 watching. Also, a nod to your editor and/or sound person…couldn’t hear the traffic at all at 19:33 ;)

6:39 best part of the video😂🤙🏽

My 2015 S5 is stage 1 from IE. My stock 0-60 was 4.69 vs stage 1 0-60 4.1. That’s with minimum tread on my tires and no drivetrain inserts from 032 yet. Just with a set of fresh Michelin Pilot Sport 4s I’m sure I’ll break into the 3 sec range.

Love the video bro

I’m new to the euro muscle..I have a 2012 S4 Stasis with all the updates and my harmonic balancer decided to come apart..I plan on putting my car in service mode to remove and install the new balancer...this is a great video by the way thank you for it..my question is do you need to disconnect the battery when doing the service mode..thanks again for your videos..there great 👍

Great video👍🙌..Planning to do rear brakes replacement video?

Hello Paul... Can you make a video on how to bleed the coolant im the s4 b8.5? Im planning on upgrading the heat exchanger in my car. Thank you very much...

Good video, very helpful. I've got a revo stage 1 map on my s4 at the moment which I think has really livened up the engine. After seeing this I have booked it in to have the supercharger pulley changed. i can't wait to see what results I get.

After seeing your videos and a few others, will definitely be going unitronic stage 2 - single pulley. Would it be safe to have AWE touring exhaust equipped as well or would that melt the catalytic? Appreciate your help!

Great video👍..You still doing a Diff Service Video?

Would it be possible to show a non sport diff b8.5 replace/upgrade to sport diff torque vectoring ?? I’d like to see one please Also how would you tell if you have sport suspension

Upgraded cooling next to keep the cats from melting down a bit longer?

Hi. Why my pulley belt making metallic clanking noise if I cold start the car after leaving it in the rain or cold for 2-3 days? It go away after couple minute, and you wont hear it again when you start up. Any suggestion would help. Thank you love your video

Dammit Paul, now I want to buy another B8....

That's a lot of work for a pulley but it probably well worth the upgrade 👍

Need a heat exchanger video and test pipe install.

Coming from a bmw platform I have to say the Audi is much more intimidating to work on. This looks like big hassle but I bet it’s rewarding. I have a b8.5 s4 and can’t wait to start modding it. Great videos; subscribed!

How many minutes you must heat it and on what temperature? And i want to know if you pushed all the way in ? Thank you

How about factory cooling for over compressed air?

Love the wrap,looks like DTM cars

do you press the pulley all the way up against the super charger? or do you leave like a 1mm space so that the pulley isnt rubbing?

Damn that toaster adds mad boost

Is p3 gauge able to read the oil temperature, oil pressure?

Why the need to change the pulley? How does it provide benefit?

Awesome Video!!! Don't you have to upgrade your sparks plugs as well?

i see no heat exchanger upgrade .. Is it okay to go to stage 2 single pulley with stock heat exchanger ?

Isn't that brake rotor on the wrong side? That looks a a passenger side caliper just by the way the slots are facing??

Can someone please tell me what's the number of the smaller belt for the smaller pulley Deutsche sell the kit but don't know the number for it?

Great video! Really helpful but one question: what size are the bolts for sliding the front into service position? (9:46 min) ?

Cool

Did you know you can have the supper charger out of the car faster and easier than putting the car in service mode ? 6or 8 bolts? One or two coolant hose And two connectors? If i am not mistaken, just saying

Can I upgrade my q7 need more power

Probably not worth trying this without putting it in service position?

I think it's easier to pull the supercharger and swap the pully on the bench. I worked at Audi and you can do it without pulling the nose and putting it into the service position.

I just did Unitronic Stage 3 dual pulley. Some people might not think it is justified to call it stage 3, but I can at least attest to that the "butt dyno" can't tell the difference between UNI stage 3 and APR's equivalent offering. Maybe my results are slightly off because I am using a pulley even smaller than the supplier UNI (just a slight bit more boost, peak boost is the same but the extra ratio allows the compressor to make more boost lower in the curve) but I really do think Unitronic is on to something. With their TCU stage 2 software, I was able to rev to 7300rpm, might not be alot for other engines, but with a hefty amount of boost from a high pulley ratio 7300rpm is vastly different from the 6800rpm stock limit. To most people's surprise, I do not run a heat exchanger, I just never drive the car to the point of heat soak, by monitoring IAT's through the OBD port. I really look forward to unitronic and other makers creating a (maybe lower priced?) or at least higher performance version of the fron Air-to-Water intercooler. The stock one is pathetic, designed tiny for the tiny amount of boost audi uses at stock - to maintain efficiency. The oversized, 140% larger APR offering seems to be great, but I am really hoping a company will improve on their makings. Not only is the FMIC mandatory for track days, but it really can help the car in normal driving situations, simply by providing a consistantly lower intake air temperature. Again, the lower the intake is the more stable the charge will be and the more timing you could feasibly throw at it, with water methanol for the ones that want to go ham. Anyway, that aside, great video and great car.

How long would you say this process takes?

mint

do you have to get a tune for just a single pulley? i have a6 3.0t

Great video guys, very informative, I use 99oct on my S5, as I have a convertible what sort of 0-60 times do you feel I would get? Perhaps increased by half a second 4ish?

So is this all road legal in your home town? No issues with the police or vehicle control?

Kewl

Do you need tcu tune with stage 2 or dsg clutches will handle the power perfectly fine?

Damn 134,000 miles. Im over here about to buy an s4 and wont even consider one with 30,000 miles lol. I want mine to be a baby because Im planning on keeping it for a long time. Willing to spend 35k if I have to, fuck it.

Would there be any issue running the pulley/tune with a 6spd manual? Thinking about clutch slipping with the extra power and torque from the stage 2. My B8 has about 45,000 miles and the clutch seems to be slipping occasionally during hard driving.

So why unitronic? I’m debating on different tuning companies and I’m having trouble deciding which to choose. I love the numbers unitronic offers and the discounts for pairing tunes but so many people vouch for APR, IE, GIAC, 034 .. etc. I’m just uncertain why one would Be better or preferred. Anyone have some input?

I got a 2013 s4 and I did the pulley upgrade and put the new belt and a couple days later the belt got ripped in half. put another belt and the same thing happened, any information on how to fix this problem? Please let me know

This sounds great.. approx how much would the cost be to do this?

Could you see any other issues arising from this upgrade other than fuel budget and burnt rubber? 😜. But for real, like any transmission issues from producing more power than it might be designed for?

Question all the mods you did on the b8.5 s4 are they the same on the b8 s4?

Downhill??

3.5 0-60 that’s insane

Would you mind sharing with me a reference for your service position bolts? I’m unable to locate it in the description

How many miles are on the s4 now? I'm debating on ~90k miles or spend the extra and get one with ~50k

Do you have to install the stage 1 and stage 2 chip tune or can you skip the stage 1 chip and go straight to stage 2 chip tune?

? Downhill?

Where can i pick up those hanger studs? Or what are the dimensions?

In my opinion it would be easier to remove the SC to make the pulley installation and removal easier. Not that much work, just need some new gaskets for the intake manifolds and top off the coolant.

Link to the digital gauge you have installed?

And how will the S-Tronic cope with the "huge" amound of HP and TQ :)

Where’s the link for the cable?

obviously

I’m new to the German car world. My 2013 S5 I will just pay people to do this for me. Lol

Pulley woth tomato sauce 400g for 2 h yummy 😋

What's the difference in gas consumption between stock and stage 2?

What are the diameter and weight of these pulleys? Final ratio?

Please help me find a electric steering rack for 2013 Audi S4 B8.5 with dynamic. I’ve looked all over the country for a used one because I’m a broke college student lol

Pro tip, an air fryer set to 400 for 20 mins works

Why not just cut the pulley off with a cutoff wheel ? like on a v cut into the pullet....And install new pulley? I think I am going to fabricate a tool to get into the vee that I cut into the pulley to break the last remnants of thickness on the pulley...hopefully 15 minute job....bake the other new pullet and slide it on with the new belt

So this is not a turbo? What is a 3.0t?

does this car really has 134k miles or there are kilimeters?

supercharging a toaster oven to heat quicker.

S5 gets no love?

Lookin’ awfully low on coolant!

Why the hell did she pull the bumper cover your video showed nothing around there except for pulling the pulley off

I think it was going downhill for this 0-60

Tool removal very pricey!! Barely gonna use it

3 and half seconds 0-60 on just a pulley and tune? Wtf that is supercar speed. I only got 280hp on my 2.0t tuned 😭😭😭

why didnt you just remove the supercharger? takes 10 min

why tf is the puller 220 dollars

Yeahhhhhh I'd rather pay someone to do it. Fuck that

Iam cutting a slit in the plastic of mine not taking crap off 😂😂😂 no one will ever see it and if they do who cares my cars not for sale

WTF???? WHY???.... you disamble the whole front???...instead just remove the Supercharger itself?! unnessesary work! disambling whohle front: 1-2h! disambling supercharger only: 20-30min!
