Project Audi S5 3.0 TFSI - Now Stage 2+ with upgraded supercharger pulley!
Audi A6 / S4 / S5 3.0 TFSI Supercharger Pulleys Now In Stock!
What's the car like to drive when it's standard?
The Audi S4 / S5 carries the 3.0 TFSI engine which is a supercharged V6 producing 330bhp and 420nm from standard. The car is very refined to drive, has a bit more excitement than the older 4.2 litre V8 and has a great rasp from the exhaust when you blip the throttle. Unfortunately the supercharger whine cannot really be heard which is a bit disappointing to car enthusiasts and the supercharger bleeds off it's boost at the top end which is not very satisfying and you get the feeling that Audi have only done this to meet their pre-determined engineering target of 330bhp. You get the feeling the 3.0 TFSI has a lot more to give, and as our development and testing shows - it has.
Stage 1 - ECU Remap
Stage 1 is an ECU remap designed for a completely standard vehicle and dramatically increases the power available to the 3.0 TFSI engine. The characteristics of the supercharger bypass valve are changed so that more boost and torque is held in the higher rev band. Combining this with timing, fuelling and torque limiter adjustments, this upgrade gives the typical 3.0 TFSI engine 410bhp and 500nm.
Stage 2 + - ECU Remap / Reduced Supercharger Pulley
As the supercharger is driven off the crankshaft, the only way to gain any more boost from the standard supercharger is to fit a slightly smaller pulley. The reduced circumference makes the supercharger spin faster and therefore create more boost. The upgraded supercharger pulley, combined with a More-BHP Stage 2+ remap gives the 3.0 TFSI an additional 0.2 bar of boost pressure which is enough to propel the Audi S5 to 450bhp and 550nm.
Coming next - S-Tronic DSG DL501 Gearbox remap!
Remaps can be tailored to suit fuel grade used, for example regular or super unleaded petrol. For the best power results we recommend that petrol cars be run on super unleaded.
Where the vehicle allows we can also add features such as speed limit removal, increased rev limit, launch limiter, hardcut limiter, exhaust flaps open, sports display dials adjustment, cold start off, Decat MIL off, DPF off, EGR disable, DTC (Diagnostic Trouble Code) removal and remap on the sport button.
As well as MoreBHP HQ in Crewe, tried and tested MoreBHP Remaps are also available at a few carefully selected and exclusively authorised MoreBHP Dealers; BVR Automotive in Stoke, VRT in Slough, Shaikly Motor Company in Essex, Nordic Motortuning in Norway, Diagnose service in Norway, BPS Autos in Australia and ATA Tuning in China.
