RSX Piston Meltdown
From fuel injection Section - Rick's Tank's at the Race Track
302cu, 9.5cr, 10-12 psi Twin Turbo intercooled, 750hp @ 7500rpm. (2.5hp/cu)
My EGT's would hit 1400-1500 as I kept my foot into it.
The only way to lower my EGT's was by increasing timing. I would guess I'm transferring the heat into the cyl.(double edge sword, melt the turbo or melt the pistons)
I will bring CR down to around 8.5. I started at 7.5 (dished piston) and that was way too low. (lazy) 9.5 drove and performed great, but I think is too high for sustained road racing. We'll shoot for the middle.
