If you are comparing to a N/A or turbo car to a supercharged car, this statement is false.

With the supercharger you always have parasitic loss, and in tern have worse gas milage than a turbo car (every time). This is the energy/power that it takes to spin the supercharger. It is always creating pressure (positive displacement), since it is driven by the engine, and to create pressure you need energy/power.

This is also why a supercharger will always net less HP/PSI compared to any turbo (on the same platform). It can take up to 60hp to create 10psi of boost, depending on the supercharger head unit. This power never makes it to the wheels, as it is spent apinning the supercharger.

This works much like driving your car with the a/c on all the time.

Makes since to me! I don't want to through his thread off track with Turbo vs SC. Plus I know nothing about them. I do know Stillen makes a fairly decent kit if your not trying to go to the moon with max HP and it fits a limited budget.

I like what elperuano said, figure out what you need, find the kit that is best suited for you. Stillen fine for me, I don't need to have the biggest numbers on the forum.

elperuano Reliability will all depend on the tune.. Good luck with whatever kit u choose, just make sure to do lots of research before u pull the trigger. Would hate for u to get the Stillen kit and then be disappointed with the outcome. If u want power and room to grow in the future, look into turbo kits. Sasha's BP kit is good, GTM TT kits r good and S&R seems to have come out with a good kit as well. Do it right the first time and you can save yourself lot of grief and $$$$$$

I am not trying to compare the two at all. Each has it's place....just wanted to correct the fuel consumption theory.
