More like an engine loosely based on the v8-60 flathead

Sidevalve (SV) NO; is OHV (OverHead Valve).
This is the difference:
SV:
OHV:

9000 RPM is very hard to do if even possible. But i dit make a OHV engine capable of 360 HP at 8900 RPM, so pretty close to 9000 RPM.

Posted: Mon Jul 21, 2014 9:20 amSorry my friend, but that engine only gets max power at 8200 RPM. My engine at 8900 RPM. And you compare your turbo engine whit an NA engine.
But if its max RPM we are after, beating you is not a problem. My engines displacement is more or less the same as your engine this time. I will let the image speak for them self.
First N/A engine
Turbo LF (LF = long life) engine:
Turbo max power but low life engine:
