HELP! 10V Turbo I-5 piston sources needed!!!

[Michael Gough]

Ya I heard similar things about my JT turbo motor blowing up, knocking like
crazy, melting pistons etc with (gasp) 8.5:1 compression. Funny...it ran
happily at 12psi on 91 octane after I got the bugs worked out. Never pushed
it farther than that, so I don't know what the upper limit would have been.
8.5:1 is easy stuff, especially with the MACxx ignition mapped for boost.
For your KH, the difference between 8.3 and 8.5 is so slight, that it's
really not something to even think twice about.
