It's definitely no slouch as with the 3.0 liter blower at 11 psi on 91 octane pump gas the Weistec Stage III setup is capable of 630 wheel horsepower, impressive. The HPF Stage 3 on 91 octane puts down 642 rear wheel horsepower. So, on 91 pump this would be a pretty interesting race.
The E46 M3 is not on pump though (meth is used but whether it is meth and pump or meth and race gas is unknown) and with its weight advantage it shows. Impressive pull against a stout car. Thank you to BenzBoost member @bilal for the video.
