Re: superchargers for 4ltr 6cyl
Easy answer is to put a turbo on it mate. Much better torque and .....wait for it....usually more power. No belts either. Those powerdynes are not noted for thier reliability.
Powerdynes and Vortecs are great but they need a few revs to start making a descent difference.
Twin screws are better but development of them for the 6 isn't really there.
The upgrade kit is for holden factory s/c engines i think.
Turbo can be done under $6000. Correct tuning method is the main hurdle. Don't cut corners here! Mild setup on around 7psi could have you up around 180-200rwkw. Theres plenty of great sucess stories out there for you.
I'm happy enough with the Turbo that i'm doing some development of my own on a V8 windsor... And i've had a Vortec.
347 238rwkw untuned and with a couple more lil things to change :)
