Torque more important than BHP?

The full miltek system is louder than mine under power but sounds quieter than mine when cruising. But then Graham's car is geared higher as mine is a facelift his isn't.

to fool the Mrs... slightly crack both windows... it's amazing how much quieter it is

Please can I add the following that may clarify the power/torque debate:


Power [kW] = (2 * pi * (engine speed [rpm]/60) * Torque [Nm])/1000

As you can see, engine power increases in proportion with engine speed and torque. So, it is very desirable to tune the fattest torque curve you can across the whole engine speed range in order to satisfy mid-range driveability and peak power requirements. It can be said that Power is, in effect, the rate of change of work done [i.e. torque] from the above equation.

A tuners aim is to maximise the engine torque at peak engine speed by maximising the airflow through the engine and achieving the largest (safe) cylinder pressure the combustion system can withstand.

So, in answer to your question "is torque more important than bhp?", torque is power therefore is equally important and relevant.

You geek but a very valid point
