On 93 octane pump gas the supercharged car puts down 562 wheel horsepower in STD correction. In SAE the result is 550 wheel horsepower. Conditions were warm in the 90 degree range. Definitely impressive but it would be great to know at what boost levels this rear wheel horsepower was reached.
Regardless, this supercharger will add in the 140 rear wheel horsepower range to an M5/M6 S85 V10 on pump gas. Graphs and photos below, nicely done Velos!
