Agree, Aaron BUT. How about you post up some piston specs (for the typical Pontiac buyer) from any catalog that shows a CYLINDER PRESSURE SPEC for the piston vs the Advertised Compression Ratio spec (typically advertised in the paperwork). Also post up the other specs: Camshaft specs, camshaft lobe positions, variable or fixed camshaft phasing, .................................................. ........................... Pressure sensors you used to take the readings Kistler or others.
Also post up the new slang words used around the local Drive-In:
"My Pressure per Crank Angle Degree is bigger than your Pressure per Crank Angle Degree."
Much more useful for the average first time Boosted Engine Guy to say:
Charlie66 has a 8.75 to 1 Compression Ratio engine with XXX Turbo Camshaft and YYY volume cylinder heads, with ZZZ head gasket and BBB dish volume in his pistons and can make 750 hp with a 194 cid Pontiac engine at 35 psi of boost pressure.
How about we have a vote (poll) on which way is more useful for the typical Boost Guy.
