Just looking to share info and see what everyone is seeing for max timing on 92 octane before having to add meth or something else.


mine is between 17 and 15 degree right on under wot max airflow.

 

Sounds like the area i was in on 93 i believe.
how much psi

 

16-17 psi peak

 

I was doing more boost at the same timing. This is lnf?

 

His signature says 07 SS/SC

 

Yep lsj

 

sounds about right... I was doing around 18-19 degrees of timing on 93 pump and 2.8" pulley. About the most we could run or car would start breaking up. My car loved high timing.

I ran 25 degrees on e85, 80s, and 2.7 pulley w/ ported m62

 

Mine tapers to 15 at peak. Without a dyno it would be hard to tell but I think I may start to add a little bit of timing into the mix and while keeping an eye on knock and see if it picks up a bit.

 

Thanks for sharing info!
