Phil,
Do you know anyone using the Folk Lift (H20) Pistons?
I expect they would hold up fine, but the folk lifts do not rev
over 1,500 rpm in their original application. With the roadster
valve springs, I know folks who run the H20 engines to 7,000
rpm. Not sure if the piston can handle a turbo load.
Compression vs. PSI reading... one of my favorite trivia questions!
While you might think that 188/14.7 = C.R. doesn't work that
way. As you compress the air, it will heat up and expand. So you
get a much higher reading than the cylinder compression would
explain.
Still 188 PSI is a good reading, but it is also common for the carbon
to build up in the piston chambers. I explained to a friend how to remove
the carbon by "steam cleaning" the engine by reving the engine to 3,000
rpm while pouring water into the carbs. Uh... you know a bent rod makes
a really funny noise?
Cheers,
Tom Walter '68 roadster -- lowest ground clearance
Austin, TX '99 Maxima -- 3" higher
'84 Land Cruiser -- just crawls over roadsters.
