If you ran the JRSC on a stock internal block at 12.5 psi your effective compression would be 17.76 to 1.
(9.6 x:1 times 12.5psi=17.76 x:1)

boost is actually less stressful (at a conservative boost setting) than increasing engine rpm. inertia loads (compressive and tensile) increase proportional the the rpm SQUARED. so if you double the rpm you increase the inertia loads FOUR TIMES. boost is good because it increases cylinder pressure over the entire power stroke.
Power= effective pressure x length of the stroke x area of the bore x ( #of cylinders x rpm/2) if you double the effective pressure the peak pressure will only be increased by approx. 20% because it is over the entire power stroke and peak pressure is reach after about 18-20% of the mixture has burned so if you double the mixture 18-20% will also have burned when you reach peak pressure. as the crank reaches 90 degrees pressure will be much greater under boost but LESS than peak pressure. :D

Joe what ever you get let me know. and i will take the pics for u:D
