i am running conservative timing for pump gas, and race gas allows more timing. i turn up the boost a little to make up for the low timing, however it is still technically 'untuned' because the car has never had c16 in it on the dyno. my tuner is the one who told me when i asked, that if i wanted to run race gas, keep it under 30 psi and data log every run and see what happens. i have gotten it up to 28-29 psi on a cool night before getting any knock, so this night i only went to 27.
the motor has since then shown signs of being hurt, but i believe it is from a head lifting and breaking the seal of a head gasket slightly, because now under hard boost it spits coolant out of the overflow tank. thus the built engine going in to handle the turbo.
nevernufftorq- who did you have build your sti if you don't mind me asking? i'm considering having phil at element tuning build my longblock or ron at raw1performance.
upsidedown- man you know you can have antilag and launch control! standalone. i have hydra 2.6 MUCH better than an accessport.
turbodave did it all at r and d auto
mahle oistons, carillo rods, valve train, cams and all the port work on the head which is let's just say substantial
