Question about supercharging and how it affects your engine?

vetteeatr · 02-13-2002, 08:34 AM

I want a street driven car that isnt exactly the best ride but can be driven on the street with appoximately 500-550 RWHP.

You can see my mod son my sig but i think once i do a little cam swapping and porting and polishing along wiht a conversion to mass air and upgrade a few compnents i plan to be near 400 RWHP N/A so if i get a 30% boost I will be in my range of what i desire so teh compression doestn really need to be that high.

I would prefer the engine to never see above 6500 RPM

I hope this is what oyu mean

Basically I want a really quick barely legal street car
(Also. i realized abotu teh fuel system upgrade i more ment how do i need to design my combo for optimum forced induction such as teh diffrent sizes of ports and intake choices, shoudl i upgrade to 75 mm thorttle body and not have to sell a 70mm when i upgrade evreything?

I dotn really got the money to buil agood motor then ditch nearly all of it and rebuild another one i woudl prefer to build a motor that woudl be quick but not the best it can be N/A and jsut wait till ic an afford the supercharger.

Thanks Guys
