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

Click here if you want to calculate your 1/4 mile times from the bhp.

Please use the feedback form at the bottom to tell us what you actually got on a rolling road, which car it was & which mods you did - this helps us to make this more accurate for everyone!!!

    I have a mk5 vw golf 1.6 fsi. The power calculator on site said that with a turbo added (car has not turbo currently)the bhp will go from 115 to almost 150 !! So I am ver keen to fit said turbo.

    Is there anyone out there who can tell me what cheap turbos are suitable for my car ???
