Compression Ratio Vs Cylinder Fill

[Stan Weiss]

I would be interested if anyone else did these calculations what they come up with.
Bore = 4.155"
Stroke = 3.5"
Rod = 6"
IVC = 76 ABDC (36/76 - 292 seat-to-seat - 110 ICL)
VE = 100%

cylinder pressure around 47.1" hg @ IVC
Stan

What is the projected compression pressure ?

About 407 psi / 828.5" hg

Mark, you don’t have a video of that engine in the hoist, do you?

Luckily, that was before the cell phone was invented.

Well dad gum Mark don't leave us wondering-------WHAT happened with the cranked engine on the engine hoist.... Mark H.

I'd guess the torque reaction when the throttle was blipped, or even just when it fired if the throttle was partially open, flipped over the hoist.
