Almost any charger will fit on any car, at the end of the day, the only constaits are space.

If you put in some time and effort - and a little creative thinking, anything is possible

And on a seperate note: What do you reacon the chances are of connecting the electro-magnetic clutch off an air-con unit to the supercharger - allonging me to turn the supercharger on/off at will (for those moments when you dont want to let the idiot in the lane next to you know that your boosted) - a possibility? And is there any technical reason why a dump valve woulnt work on a s/c car.

Thanks!

Stock is 3.0" pulley = 3-4 psi
My 2.6" pulley = 7-8 psi
2.3" pulley (sitting in my back seat) 10-11 psi


Why? Under no load/low load there really isn't any boost. The dump valve really isn't necessary due to the fact most superchargers have a bypass valve bolted on them already....in between the supercharger and intake manfold.




In terms of boost, how much is 3-4 psi?? In terms of gains...

In reality I don't know. Never dynoed. At 7 psi I gained 40 hp at the wheels.

In a perfect word, you would have 27% more power. Your crank HP would go from 130 to 165. If you have a crappy intercooler, or don't have it tuned properly, that value drops.

((Boost+14.7)/14.7)-1=%HP Gain

4psi=27% Gain
7psi=48% Gain
10psi=68% Gain
14psi=95% Gain

Just think about it. Atmospheric pressure is 14.7psi. If you double the pressure, you double the power.
