Re: An intresting thaught re Compression
yes all very true,
but in boost aplications you dont want to run the standard piston in any application past 15 psi.
as far as i know, acl dont make a race series piston yet for the au (could be wrong now, as i checked 8 months ago).
you actually dont really need to drop compression on a ea motor to run 20-25 psi. 8.8 is already low enuf. the later model cars (ed newer) to drop compression grab a set of acl race series ea pistons, 20 thou over size and have ur bottom end honed out 3 thou to accept the pistons, the acl race ea piston has a 11.8cc dish, the acl race ed and newer has a 5.8cc dish.
the au rod is 6.05 inches long the pre au is 5.88 inches long, check the pin heights and dech heights if ur thinking of running au rods in an older car.
