1241, Acceptable Air Intake Temps??
Posted by RxR_Eclipse, Dec-31-69 06:00 PM
Ok guys did some tuning the other night at the track and got the a/f down to about 11.8 so I'm happy there, but I did notice that my intake temps were up around 112 deg. Is that ok? I just put on a new intercooler and would have thought they to be a bit lower.
FYI
15 psi
dsm 450's
s16G etc etc
IC is 18*3.5*6 bar and plate.

I think your air temp is okay, but I think that I would run it a little more richer like around 11.1 to 11.2 at 15 psi.

really, I started at about 10.5(which blew tons of black smoke) and moved my way up to where im at now. This feels really powerfull and egts only get just a hair above 1550. Although they climb quickly.

Does your EGTs stop at 1550 or will it keep climbing if you keep into it? But, I would say as long as your EGTs are good and you have no detonation then I would say your A/F ratio is fine. I guess my engine just likes to run a little richer. Mine seems to like 11.1 at 16psi.

Mid 10s is too rich. You can safely do low 11s on a dyno and high 11s on the street.

the gauge goes up to 1575 max and levels off, I have seen it run up to 16, but that was at part throttle and the old sfmu setup. I should be at the dyno in the next 3 weeks or so, so any advise on final tune is awsome.
