how much timing on a built z6
most of you know my setup, my buddy who helped me with the initial tune on my unbuilt motor was used to his y8, and runs alot less timing. I talked to him the other day and he said he was looking over some peoples crome maps and they were running way more timing than i was. I didnt put the 2.5 bar map in yet, but the 11.03 column is set to 19.65 or something. i also just saw someone elses map that was running almost 30 degrees to 8psi. i think mine is at like 22? anyone have a screenshot of a built d timing map?

Re: how much timing on a built z6
30 degrees is recockulous, who ever made that map is retarded, whats your c/r? how much boost? like 9:1 c/r and under 13-14 psi i wouldnt be afaid to run like 24 degrees of timing on a built motor, as long as it has the fuel map tuned to BELOW 12:1 afr's, like 11.8:1 or so, you could get a few extra ponies with 1.5-2 more deg. of timing, but dont push it, its a shame to blow a built motor, i have done it!

Re: how much timing on a built z6
wow! my timing i belive is around 14.. My buddy tuned for free and doesnt waana be responsible for blowing my motor until i get a more knowledgeable tuner on the dyno. My setup is z6 block y 8 head. Im yielding roughly 8:1 C/R!! I just go tmy 2.5 bar and hittin the dyno soon. Is there an appx. hp per degree of timing?

Are you sure that 30* wasn't BEFORE boost retard was set? I got a map from an unmentioned "tuner" on here and it had the timing set at 29* at the top of the map.
