Hay, Ed, I always thought 15 Psi
boost was about only 30" Hg of boost-atmospheric pressure (about 15 Psi)
equals only (about ) 30" Hg. Where did I go wrong?

Should be a fire belching
dragon of an engine at over 15psi, Greg.
15 Psi boost would
be roughly 60” Hg of boost which at an A/F ratio of 12 (assume you would
run it a bit rich at those boost levels) would give at 6000 rpm approx 550 HP
burning 51 gph (more power at high rpm and boost naturally) and
producing a total of 25000 BTU/Min of heat to be dumped through the
radiator and oil cooler. Boy, you will produce more heat energy that gets
dumped through your oil cooler (8484 BTU/Min) than my total (coolant and oil
heat) entire engine puts out. Hope you have big radiators and oil cooler
{:>).
