Reply to "351c EFI intake manifold"

Doug,
If your friend is running 40 PSI boost on a SBC and only getting 1000 hp then he is doing something seriously wrong. A 40 psi boost level on a 350 should make over 2500 hp. You can get 1000 hp with only 15 psi. I get 600 hp with only 8 psi and no intercoolers.

And intake tuning also helps a supercharged car. The long and short runner still helps. Its just not easy to get long runners when you mount an 8-71 GMC blower so they are usually short. All a supercharging device does is to make the atmospheric pressure appear to be higher than normal. Since there is so much of a power increase, people may not know they are not getting all that could be had. Even a poor intake system will make more power than a good design N/A engine.
