what did it run with what mods

[tenpin784]

Mods: L32 block w/ Gen 3 Eaton M90 Blower, Intercooled, 3.2" pulley, Wizair CAI, Custom-Tuned PCM, TOG headers/RT DP, 1:9 Rockers, 42.5# injectors, Poly Motor Mounts, AutoLite 104's, and 180 TStat

IT was 269WHP and 357WTQ

really? thats all you could get out of it? how many degrees of timing are you commanding?

[tenpin784]

Stock + 2 (which I think equates to 18.5 or so).

My car always has knock even though it is intercooled, and now its cam'd too.

and 269WHP isnt to bad, thats ~330 to the crank, which is 90HP above stock.

[lurch1489]

stock timing iirc is 12* so you would only have 14* total, you need to go back to like a 3.3 or 3.4 pulley and add timing, 18-20 is ideal.
