The pulley is CNC machined from high-grade stainless steel and designed with a smaller radius than the factory pulley fitted to the Eaton TVS Supercharger. When combined with Revo's Stage1+ calibration this allows us to further optimise your vehicle making use of the increase in supercharger rpm and improving on the performance you’re used to with our Stage1 performance software. There is a huge improvement in both power and torque throughout the rev-range, showing more than 100hp and up to 90lbft at the wheels over stock performance. On the road, this translates to a more flexible engine with more midrange and a lot more ‘punch’ lower down than both a stock or Stage1 vehicle. Performance testing of our own S5 Coupe shows consistent improvements over OEM and stage 1, with repeatable 3.7 second 0-60mph and 8.8 second 0 – 100mph times. Regardless of times, facts or figures a Stage1+ 3.0TFSI makes for a very fast and enjoyable car to drive.
