The BMW E90 M3 might’ve gone out of production but for a big number of fans out there, it will forever be living in their hearts. The 4-liter V8 it used to come with is still widely regarded as one of the best sounding engines BMW ever made. Too bad, then, that it was only good for 420 HP and some 400 Nm (295 lb-ft) of torque. For that issue, the guys over at G-Power might have the best solution.

Their arsenal includes a wide variety of supercharging kits that can take your M3 from the stock 420 HP reading to as high as 740 HP. Needless to say that the latter figure will transform basically any car into something close to supercar status. It’s not exactly the case of the car we’re watching here but it’s close nonetheless. The uploader didn’t specify any exact figure but judging by the cars this BMW is racing, we’re guessing the power output of the V8 under the hood was taken up to around 650 HP.


That’s because the M3 is racing a Chevrolet Corvette Z06 on that very damp track, a car that has a 6.2-liter supercharged V8 on board, making 650 HP in standard guise. You can tell that’s a Z06 by the red brake calipers as there are few visual indicators of differences between the standard Corvette and the upgraded one. Since the BMW was capable of keeping up with the American, we’re guessing forced induction was involved here.

In turn, that would mean that the S65 unit received a G-Power SKII CS kit that takes the power output up from 420 HP to 630 HP, just enough to keep up with the Vette. Chip in the faster 7-speed DCT gearbox and the BMW might stand a chance, even though the Chevy is a bit lighter on its feet. However, anything can happen on a wet track such as that one, especially with rear-wheel drive and we have to applaud the drivers for how well they managed to control their cars in the given conditions.
