TorqueCars power gain calculator (NASP engines)
"Absolute Power corrupts Absolutely"
Please note that this calculator cannot be more than 80% accurate for every make and model as parts and condition of car will vary dramatically any expected gains.
It does not take into account the age of a car and is representative of a typical hot hatch and is intended for fun use only no claims or quotes can be verified as accurate for your car.
Generally the more boxes you tick the less accurate the calculator will be (2 -4 boxes should be fairly accurate).
This is for NASP engines if you have a TURBO charged engine click here
