I have been looking around and seeing a lot of different answers. How much hp can these motors handle without being a ticking time bomb, and what kinda power are people making on 93 octane? Thanks, Joey
Roughly 450 is about the safe limit. Must have a safe tune. Any hint of detonation and its all over.
thats what I hear. Out of curiosity.. does the s197 3v motor handle boost better than our 4v's? It's common to see those boosted motors with a stock bottom end running 480'ish.
The 3v has the same internals as the 4v, and the same block as the mach1 I'm led to believe.
I've seen a few run for years on ~470whp, but 450 is the "omg i want it to last" number,
Agreed, tune and driving style are to variables that affect reliability at 450rwhp. To Kevin's point a buddy of mine just blew his recently forged motor, not sure what let go yet but my guess is it went lean with just a focus pump and BAP.
