can 93 octane measure up to that much timing? because thats what mine is set at right now just to lean it out.

just to lean it out?

i think 17 is just right actually, lower it just a notch if you don't think its right.


i thought you were selling it?

heres my guess....people say 14* for premium (which prolly is 91), so 93 would prolly be good for 16

i wish sunoco still sold 94

I run about 14-15 on 89 gas on my stocker

i am still selling it just no real offers. i did have one though someone asked if i would trade it to them for a 89 dodge daytona and 92 cavalier.

and yes 2kwik to lean it out. i have the fpr turned all the way down and it was still loading up @ 15 degrees of timing. i honestly still think it needs at least another degree of timing for it to stop running so rich.

but according to a desk top dyno she should be putting down about 325 to the wheels with stock e7 heads

i'm running 18* on the street and 20* at the track....if your engine burns it right...cam timing/spark/right air.

there won't be any issues.

Can you go overboard with timing? Would bumpin it to like 30 be too much, assuming you have the proper fuel to compensate (eg.110 race fuel)

thanks grabbem.

im running 21 degrees now, used 110 octane for a while then started using 93 to see, and it still runs fine, no noises even under heavy load.
