Dude......

You won't stop, till you go pop! Huh?

Got all your reliability mods?

Got water injection? Helps you run much higher boost and will keep you from going lean and !POP!

Got a great, no AWESOME tuner w/dyno?

Got a Viper/Bosche/Cosmo fuel pump? <--my guess

Give a complete list of your mods so the gurus on this forum can help you out.

for 24 psi you will most definately need race gas, I wouldnt really run over 18 PSI on pump gas if i were you, you are risking detonation.

You may want to run a upgraded radiator if you havnt already done so.

ok no water injection ....but please tell me more about this please .......uuhhh also no upgraded radiator (car has never over heated anyway)got cosmo 3 rotor pump
running about 12-10 degrees timing @18-20psi with a split of about 5-4 degrees have a rising rate fuel pressure regulator ....no dyno down here so cant give any solid figures (sorry)only thing i have noticed after a strong run is that the car idles a bit sluggish for a while but aflter about half a minute it runs normal engine has just been rebuilt everithing is new and properly broken in i also have the hurley engineering seals...engine is street ported and have already installed nitrous on the car but havent tested it yet ....please do inform me more about this water injection thing ...ive heard of it before but never gone into it ........

Serch around for a "Y-Band" Air/Fuel engine analyzer... and make dame sure your A/F ratios remain about 10 : 1 under boost.... Unless you're partial to driving a grenade with the accellerator being the safety pin. The analyzer has a hand-held " commander display" like the size and shape of the PFC's, plugs into you cigarette lighter for power, with an O2 sensor thats placed in your exhaust tip. You can also hookup the O2 sensor into the D/pipe if desired... Then, you'll be capable of monitoring your Air/Fuel ratios dynamically (as you drive). Cost? About the same as a PowerFC but still half the price of reman engine. My 2 cents

uhhh i forgot to mention i do have haltech ...so far the tunning hasnt gone that bad my exhaust temp reads 1000deg celsius (this is apexi egt gauge )its located in the manifold in front of the turbo dont know if thats too high or not i ve been told that it holds and so far it has can i use my haltech read out on the o2 sensor also to tune ????
how bout some info on that water injection????
