Forced induction timing and air fuel?
Hey guys, the general consesus is that around 14* of timing and 11.5:1 air fuel ratio is safe for stock motors. Just curious to what your settings are or what you shoot for when tuning? How would you set up a stock ls6, paxton novi, headers and meth.
Thanks

You can set a baseline for initial street tuning at 14 degrees, but the dyno will let you know what the car really likes......which in my case was 20.

I had my STS cranked up to 11 PSI on a stock bottom end plus higher compression Patriot heads. I started at 10* then just logged and looked for knock retard and backed it off till there was none, motor has held together for a year, and I am not exactly....well.. gentle

Wow 20* of timing. Well at least I know I can go up. Mine is like 10* and 10.0 to 1 AFR. Plan on runing more timing and leaner mixture say 11.5 to 1, and 15*(now that I have an intercooler). I am also on stock long block with 106,000 on the clock, heads never pulled! Plan on running 8-10psi real soon.
We will see how it goes, should be done next month for sure.

If you are running meth i would lean it out a little more and throw more timing at it. What mix are you running? What nozzle size?
For a comparo,
Im running a stock motor'd lsj (s/c cobalt)
28 psi, a 11.8afr at toe in leaning up to a 12.3 at redline and 21* timing on a 50/50 mix and 5gph nozzle.
