engine is about 300 hp currently
im just curious how much hp i could get per psi assuming engine stays stock
just thinking on 100 hp of boost instead of 100 hp of nos and no lag as cr remains the same.
i was thinking i could run 5 psi without needing an intercooler and engine should take it, but what power woold be achieved roughly ?
Isnt as simple as that. And I would say that those turbos are a bit small unless you're operating over a very small rpm range.
5psi should be ok with no intercooler, obviously will good control over ign timing and fuelling though
If you worked on the theory that 1bar ie atmospheric allows 300bhp, then in theory 2 bar could allow 600bhp ( in that ideal world ), but obviously it wont. I cant see 5psi giving you another 100bhp though. And doing such a conversion for anything less would be a total waste of time.
You could probably get the extra 100bhp through n/a tuning
