[QUOTE="blownstang4.6, post: 16313968, member: 129006"] You're going to see 14-15psi. Too much to not be cooled especially on an old V1 S that isn't as efficient as new blowers. My stock motor Mach makes 12.4psi at 6600rpm with the V1 S, powerpipe, 3.12, and Procharger 3 core intercooler. It's been at this psi for 3 years. Just ran 11.00 @ 126 last Friday weighing 3660lbs. It sees 140-150F Iat so nonintercooled yours is going to be well over 200F. You won't be able to put any timing in it. It'll make 500rwhp, but only for a few seconds before it heat soaks. [/QUOTE]
