Now that I can log my air temps I'm kinda worried. With around 20-22 psi with a T76 and what I'd call a medium sized air intercooler on a 347 ci sbf, I get between 190-210 at the 1/8 mile. That is high right? I need more power, I want to try 25-28 psi and/or more timing. I run about 23 degrees now on 114 octane. I'm gonna try to get some 117 octane. I'm afriad to try more timing with the boost just where it's at.
How much does the Speed Pro compensate for the high temps? Any guesses as to how much the temps will increase with 3-5 more psi? The a/f ratio doesn't seem to rise much with the air temp increase, but I'm still worried about adding timing or boost.
The a/f ratio goes up and down, and it seems like the boost follows it. The O2 says it is taking away fuel all the time, so I need to take out some fuel from the VE table. When I do that, will my a/f ratio be more of a flat line? BTW, my target a/f is 11.2, way too rich or just a little safe?
One more thing, has anyone ever hear of or tried spraying CO2 or nitrous on an intercooler? I can rig up a set up to spray nitrous on the ic during or just before the run. I can also go to a bigger air/air or I think have mine moddified for water. Any thoughts?
Thanks!
