Thanks, now I get it. So if I wanted more low down torque, what's the most effective way please? I am very keen not to change the look of the car, simply to give it more go. If I did go the supercharger route, how driveable is the car? Are you simply lining the pockets of the tyre manufacturers or can you put the power onto the road effectively? Having a go first is certainly sounding like the right advice.
