LS2 WOT timing question I have an 06 MN6 corvette.
Current mods are Vararam, Full 3 inch Z06 exhaust and soon to have an Ls7 cam as well (dont chime in on the cam please)
Ill be doing some tuning in the next few weeks. Ive noticed my stock timing right now is 18-20 at wot. Never seen it about 22 if I remember right.
What WOT timing are you guys running just as a ball park. I know that you can sometimes add timing to the point that youre not gaining any more power but not seeing knock..
My c5 was at 26 degrees at WOT.
What would you guys say I should shoot for?

There isnt a general rule of thumb or an average that people usually see? I was thinking of starting around 24 degrees and see.. Unfortunately I wont be able to dyno it for a while. This will just be street tuning
My bolt-on LS2 liked somewhere between 26-28* of timing at WOT with something like 12.4-12.6 AFR.
Yours might be a bit less with the slightly bigger cam, but low-mids 20s should be good and still be safe.

Without a dyno it's pointless, but you can try:
Ramping up to 26 by 3000 rpm, then ramp down around peak torque (~4200). Hold that timing for about 1000 rpms (5200) then ramp back up to 26 in the high end.
That should be pretty safe on a stock internal LS2.
