This guy keeps owning himself. People seem to think that manifold pressure is going to make bearings and valve guides die. ******* morons. My favorite is the part about manifold pressure increasing with rpm. lol

he's saying cylinder pressure, not manifold pressure.....

we add fuel and retard timing to reduce cylinder pressures away from TDC.....


your engine is 20% safer if you shift at 6K vs. 7K in relation to cylinder pressure IIRC.

I think people there have unrealistic expectations about what their engines are capable of.

that's more piston acceleration than pressure. knock resistance goes up with rpm. blows your mind, not your motor.

"So no Hydras yet... this is promising. "

yes, if you just set hydra in the passenger seat, the car is safe.

It is not that. Prolly it was the PC-Pro joke. I guess he is afraid from Tom coming back and starting some long thread drift out of it ...

they get locked because you guys aren't nearly subtle enough. if you want to have fun, you have to make it less obvious.
