thats a pritty big charger. what kinda power outputs are you looking at running?
what kinda engine mods? head work cam????
it would prob be easyer doing a turbo setup.
as then you don't have to worry about mounting brakets, blower belts, custom crank pully etc.

That style of centrifical blower isnt much good for low down torque, they deliver boost very linear, for example 2 psi at 2000 rpm 3 at 3000 4 at 4000 ect so if you want 10 psi thats no sweat but you'll only have it at maximum rpm. Belts are an issue in water and mud. A turbo or a Positive displacement blower are better for 4wd. A PD blower produces pretty much the same boost throughout the rev range as they displace the same volume of air every revolution, unlike the centrifical type on ebay.
Turbos the way to go.

Right well that explains that little issue away, might have to wait till teh EFI motor craps itself and see what finds its way in there after that. Thanks lads.
