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
