Torquecars power gain calculator

"Absolute Power corrupts Absolutely"

Please note that this calculator cannot be more than 80% accurate for every make and model and 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).

Model:
Standard Bhp from makers figures for an unmodified car: bhp

Full Sports Exhaust This is intended to show that to get the maximum benefit from 1 item you must add other items. IE the turbo is useless unless you add a sports exhaust.

(It is not practical in the real world to add all of the items but we allow it in this simulation and you will see that it is easier to buy a faster car than upgrade yours!)
Fast Road Cams
Fuel Pressure boost valve
Turbo Charger (or bigger turbo)
High flow sports Cat (not decat)
Air induction kit
Sports Computer
Sport flowed head
Bottom end engine work
NOS (nitrous oxide)
Go faster stripes and fluffy dice!!!

Approximate power after modifications have been added. bhp

The only way to tell for sure is to get your car tested on a rolling road.

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!!!
