I was wondering what the maximum potential of 92 octane fuel was before having to add race fuel. Keep in mind a stock turbo setup, or would this make a difference with an upgraded turbo system?

thanks

Really depends on ambient temperature.. if it's 100F outside I'd say around 400rwhp on stock twins even if you have a FMIC etc.... if it's 40F outside then 450+rwhp on stock twins is doable on pump gas....

As for a single turbo... Angel did 560rwhp on pump gas at 18psi if I recall correctly, on a T78 turbo.

Darren Strunk, with cams and HKS twins and high revs, made I think 620rwhp on pump gas at 17psi..

are these numbers safe numbers for regular day road use and the occasional unexpected race?

thanks
