i am going to get some new heads this week. my motor is 9.2:1 i think. im going to get the paperwork out and look in a few. but its got stock 317s on it. what compression ratio are they. and i have having a tuff as time trying to spool off the line, should i just spray a dry shot on it or knock the compression up and if so how much? im running a 2bar map and i am maxing it so i can see what the hell is going on at 20+psi. is there a diff map i can run with the stock pcm?

i was loging it at the track and all i could see is 30.5psi so -14psi and it says i was running 16psi. but i was a lot more than that.

HELP...

 

Stock chamber size for the 317's are 72cc.. Keep the comp the way it is, spray a wet shot not a dry shot.. Are you using meth on it..???

 

I would bump the comp up just a bit. A small shot will help too

 

You can you use a 3bar map like quik did

 

yes meth...and a lot of it..i was running c116 and meth at the track. what gaskets do i run the ls9 one more time or go to cometic.

maybe Stock48 would chim in, reason being that he built a hell of a motor if im thinking right.

 

Old school 3 bar, from the grand nationals, and turbo t/a mounted on the fire wall. I think Hp tuners can work it. Wow! C16 and meth..... Jeeez! What size ar housing are you using,been a few years since my turbo day's.

 

1.10ar 0.95 cold side...ill have some vid up soon

 

is there any body on here that runs a 3bar. i would like a pic of it if i could..

 

Like Danny said Quik ran one when his truck was turbod. Idk if there's any pics on here

 

i need to get up with Quik
