#4586, "RE: How much timing to pull?" In response to Reply # 2
yeah, why the heck would he 'pull' valve timing, if he could? You can do cam gears but that doesn't matter by psi, just boosted or n/a.
bagged - there's no correct answer, it all depends on the setup. Your exhaust/intake manifold design, pistons, AFR, octane, blah blah blah all influence it. I've read people running as low as 8* but as high as 20*. Best way is doing some dyno tuning with a scope or det cans if you don't have a fancy aftermarket knock sensor.

Thanks, I figured I would get that answer. I'm going to be running 93octane, so I figured it would be up around 12-15*. But all I have to pull timing is the Arc-2 which only allows you to retard the timing by a fixed 10*. You ground a wire and it retards the 10*. So, thats kinda wierd. But Maybe I'll only have to pull 10* or less, otherwise a snow stage II water/meth kit will have to be purchased
