im trying to figure out roughly how much hp per psi i will get going na to twin turbo.

5500 cc engine will remain stock at 10.5 cr
fit 2 t3 ar .48 turbos rated at about 300 hp each
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 ?
