TorqueCars power gain calculator (NASP engines)

"Absolute Power corrupts Absolutely"

Please note that this calculator is only an indication of relative gains because the specific parts used, and condition of car will vary dramatically and affect any expected gains. 

It was intended to show the investment of time and money with regard to your expected power gains.

This calculator does not take into account the condition or age of a car. It 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 and are based on average bhp increase percentages from our data.

Generally speaking if you tick more boxes the calculator will be less accurate (2 -4 boxes should be fairly accurate).

    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 ???
