No, the s54 in any form is incapable of producing 1000+ crank HP which it would need to in order to produce 850whp... High compression helps top end HP but adding boost to high compression engines doesn't fair well which is why you see so many supercharged s54 & s65 engines with less than 6lbs of boost because anymore and the high compression motor will grenade without being seriously rebuilt and stroked out. |
Apparently you've been closed off from the S54 world. HPF got a lot more power than this out of these engines 10+ years ago. That being said, the 315hp Z3 M was fast for what it was. The lights and trim indicate it was originally an S52 car that's been swapped. The gearing has also been changed. An 02 M coupe will do around 80mph in second gear. The gearing way off with the 5 speed and a redline near 8k, listen to the shift points. The rate of acceleration is way off. This car is around 450bhp, not the mid to upper 5 range claimed. At that range the car would never hook up, especially on those tires. 450-500+hp with trailing arm suspension would be a handful and the car would be more likely to be totaled than filmed before the owner learned to handle the car. The biggest downfall of the suspension layout is snap oversteer.
I'm a huge fan of these cars as well as modifying cars, but this one isn't one of my favorites. Oh and the cars outer tail light bulbs are out. Perhaps due to driving with headlights on during broad daylight for too long.
