How to get 500HP + from a B8 S4 3.0TFSi | Parts from APR, Milltek, BILSTEIN & Carbon Fibre

Do you want 500HP+ from your Supercharged 3.0TFSI B8/B8.5 S4/S5?
As you already know, the Supercharged 3.0TFSi is a hugely tunable engine with the stock figures being around 335HP and for this S4 it has been increased to over 500HP!
This S4 arrived with APR Stage 1 ECU software, unknown TCU upgrade and Carbonio Stage 2 intake upgrade and the baseline figures were 449HP & 385lbfts. To improve output above this a whole host of upgrades were installed which includes APR Ultra Charger, consisting of larger throttle body and intake pipe, APR Crank Pulley, APR Supercharger Pulley, APR Heat Exchanger and Milltek Exhaust.
These combined upgrades allow the supercharger to complete more revolutions per any given engine RPM, which generates more boost which in-turn increase horsepower and torque potential. The APR Heat Exchanger cools the coolant that goes into the supercharger heat exchanger, which reduces charge temps, especially over time and can allow the ECU to operate the engine in its higher power maps more often for consistently high power and torque output. The APR Ultra Charger de-restricts the inlet into the supercharger, maximising airflow into the key performance component.
Milltek's Resonated Exhaust with Cerekote Tips were installed to de-restrict the exhaust from the manifolds back, improving tone, increasing volume and improving the rear end aesthetic.
The BILSTEIN B12 Pro-Kit improves road holding and lowers the ride height subtly, perfect for this high-output road S4!
Baseline output = 449HP & 385lbfts
Max Gains = +72HP & 66lbfts
Peak Gains = +59HP & 66lbfts
Max output = 508HP & 451lbfts

Quality video guys, well done. That S4 is a serious and beautiful beast!

[@RegalAutosport]

Thank you so much

[@davewilliams7565]

Nice and well explained video! Getting 500+bhp out of these 3.0TFSIs is expensive! I have a stage 2 S5, with just intake pipe, airbox mod and 187mm crank pulley, so only cost about £400 over stage 1 and got 482bhp and 425lb/ft. I would have to really want to chase the figures to spend the extra £1000s for 26bhp and 25lb/ft. Good work, without guys like you there wouldn't be any advances and smiles per gallon.

[@TetrixTMM]

How did you get 482bhp from stage 2?

[@Kinofinity]

@@TetrixTMM I would imagine these figures are at the crank, My vehicle made 485 BHP & 423 ft-lbs at the crank at Awesome GTI Dyno ( DynoJet) - Stage 2 APR with 57mm supercharger pulley. Now running a 179mm lower pulley and Heat exchanger as well, but not had it on the dyno since.

I have a Stage 1 B8 S4 and can confirm just the tune transforms the car. Kinda sucks that APR discontinued the Stage 2 flash.

Thanks for sharing your enjoyment! BTW, APR do still offer stage 2 for this car and the ultra charger. Anything relating to removing cats, like on more conventional ‘stage 2’ upgrades they do not offer.

[@ahmhaa20111]

Well done gays 👍🏻 Is it WHP or crank HP ?

[@RegalAutosport]

Thank you and thanks for watching, this is crank!

[@Geogak]

those puffs of smoke from the exhaust can be an indication of knock.

[@RegalAutosport]

'puffs of smoke' - it's a new exhaust, there is always debris from manufacturing which come out when ran under high load for the first few hundred miles as it gets dislodged. We also log all of the cars we tune, so we can see from the data if there is knock, or not.

[@mcwendel8066]

This might be a stupid question but i was considering an a6 allroad and i know that it also has the 3.0 motor and similar power output as an s4. Is the allroad turbo and the s4 supercharged? Was wondering if i can still tune and get adequate power from the allroad? Thanks I’m a newbie to the Audi world

[@RegalAutosport]

No question is stupid! The A6 Allroad did come with a 3.0TFSi which is similar to the one in the S4. You can get the same/similar gains as this S4 with the same mods. To find out more, you can speak to a performance specialist by using the contact info in the description

[@TwentytenS4B8]

The A6 also has the same engine and depending on year is either supercharged or with turbo. You will gain more top end power with a turbo because it doesn't run out of breath like a SC does and is more efficient. Plus with a turbo, all you need to do is tune the ECU to get more boost. You don't need to install pulleys. You still want to upgrade the intercooler\heat exchanger when you make power upgrades to maintain lower charge air temperatures. If you don't, what will happen is the ECU will detect more knocking due to the higher temps and pull timing which will decrease power output.

[@mcwendel8066]

@@TwentytenS4B8 awesome thanks for the info!! It’s confusing because as you know Audi says 3.0 T but it’s actually supercharged guess I just wanted to confuse people LOL.

[@TwentytenS4B8]

@@mcwendel8066 Audi like all other German manufacturers likes to be unique in their verbiage. They hit a home run with the 3.0T and they decided to put a variant of that engine in other models. The SQ5 also runs this engine. And I'm pretty sure the standard Q5 also has it as an option since most have the 2.0T. Later years, they went to a turbo which really put this engine at the top of the pecking order. It is capable of generating 500 plus HP, but then it would crap all over everything else they offer. That's why the 2.5L five cylinder in the RS3, and TTRS isn't putting out the power it is capable of. Because it would then torch an RS7. Even an R8 would have its hands full running against a 2.5L or even a well tuned and upgraded 3.0T. Really late offerings of the 3.0T came with a turbo instead of the supercharger. These in my opinion are the better option because to get more boost, all you need is a tune since the ECU controls boost and no more messing with pulleys.

[@mcwendel8066]

@@TwentytenS4B8 thanks for the response! Just trying to do my homework before i pull the trigger on a car. Don’t want to buy a car to find out i have the model with no tuning capability 🤦🏼‍♂️.

[@Jeremy-km4dj]

is there room to put in a turbo? been thinking about putting a sage 2 supercharger kit and a turbo in.

[@RegalAutosport]

Not as far as we're away, compound charging will also introduce more heat into the charge system and these cars are already knock limited, so adding a turbo(s), it doesn't solve the limitation of the hardware which is causing knock limitations.

[@Dudeman9339]

If you want a turbo V6 go for an Infiniti Q50 or Q60 redsport.

[@88budz]

Is this a wise idea with the auto box? Asking as I'm genuinely curious as I've currently got a 335i and looking to sell and get one of these and I'm worried about the auto box, does a stage 2 hurt the autobox at all?

[@RegalAutosport]

Completely different gearboxes, the BMW gearbox also responds well to tuning. Of course, if the gearbox has not been maintained well and been ran in conditions which degrade it, then its life will come to an end sooner with a higher output.

[@adampennington16]

Brave not to remove the cats on a duel pulley set up!

[@RegalAutosport]

Thanks for the comment! These already have the secondary cats removed and none of our customers have had any issues with the primary, probably due to the APR software perhaps not running as aggressive ignition, overrun crackles and flames through the exhaust. All of those things degrade the cats and then when you add bad quality fuel into the mix.. it's a recipe for cat failure.

[@adampennington16]

@@RegalAutosport pretty impressive that they’ve managed to get that much power and still keep the cats at a safe temp, most other tuners recommended decats which is an engine out job. Mines still standard for now but plan to go single pulley next year 👍

[@davewilliams7565]

It's all in the mapping. Dual pulley only increases the SC speed, the mapping will control boost and exhaust temps. Max SC ratio is 3.2 on these engines. The SC cannot give any more boost, the efficiency is lost and it turns into heat gun rather than air compressor. Safe ratio is around 3 to 3.1. Also most go big on Crank rather than SC pulley as you can get a 206mm crank pulley now. Another option is move the cats to where the downpipe silencers sit away from the hot manifold.

[@davewilliams7565]

@@RegalAutosport Most melted cats are a result from improper tuning or trying to squeeze more out of the engine. Some say the earlier cars are more prone to this. Ps, these Engines don't have secondary cats.
