Engine's been proven to withstand over 500bhp with stock internals on a few R, S3 and a couple of Cupra's already so it should be the same on a CS

I'd love a video of the dash going flat out from 2nd gear though, my bet is we'd be seeing TCS flashing until end of 4th gear or even worse if we can spin 3rd with a mere stage 1. All that torque through the fronts is definitely funny for 80mph+ accelerations but probably useless in the daily range unfortunately.
