right now i am running a timing map for 92 octane gas at 22 psi. total timing at full boost is 18 degree. in anyone estimate, what would be the gain in using a timing map for c116 race fuel at this boost level with a air fuel ratio at 12.0-12.5. these maps are straight froom xs engineering for the power fc.

 

on c16, I've used as much as 35 degrees total timing at around that boost level...

 

are you sure that is not a typo error- 35 deg .

 

at 30 psi in at 32 degrees of timing on C16.

 

yeap, I'm sure. That's total timing. 7.8:1 cr motor

 

7.8:1 cr. that seem real enough. my timing map was for 9.0:1 CR with total timing at 26 deg.

 

That is on pump gas right?
