These calculators are not too trustworthy, as these cars with the sports tranny have way less power loss to the wheels than other cars. I can assure you it is flywheel power. Also, the way a car delivers kw and torque over the rev range will determine 0-100 times etc. My car hangs on to the power way longer than a stock car, so the calculator is just a guided figure at most.

I see you are in CPT. Come to the Cape STowners Dyno Day on Saturday. Starts at 08:15 and I will show you my power on the Dyno and take you for a spin so you can feel how the car delivers the power.
