    2.38", intake, no cats, timing 14 CTSV

    I was wondering how high of timing are you guying see on 93 Oct. with a 2.38", intake, no cats and stock cooling system. In the upper rpms (above 4400 rpm) I'm only able to get about 15* of timing. IATs are good (just above 100 degrees after the WOT pull). Current boost is about 15.5 psi. AFR is about 11.3 in these areas. thanks

    timing with your setup may be about right, but with these I am using the dyno, and verifying if what I'm commanding is actually giving me gains. Yes i would say it can take more, however, way to little info to go off of. IF you can strap it to a dyno, see what it wants, if you dont have that option, i would stay 14/15

    thanks.. I've also read that the knock sensors are overly sensitive. Now i haven't desensitized them in fear of blowing something but have you seen that in the past? I still need to go back out and do a few WOT pulls again to see if any other knock flares up
