The real reason the maths is difficult is because you lot are still working with that antiquated pounds per square inch nonsense. Add to that all rod loads in foot/ pounds and to cap it off temperature in degrees fahrenheit.

Then you add all your motor calc's are to be done in horse power!!

Give me strength, I bet gas blending for you guy's is a breeze.

I guess only square pistons would help.

But a nice principle post. Iain Middlebrook[/QUOTE]
