guys, the car makes 500hp on the wheels.the motor is an S50 motor.500hp is readily available at 1.2 bar boost and 730Nm torque @ 4500rpm.

the car is very fast and relaible too.
i am currently starting another project were i will be running a T66 turbo and have major weight reduction done, to achieve in the low tens if posible and trying to make 1000hp.
