12 to 12.5 is considered safe.

 

There are a lot of variables that also need to be considered. What type of gas, how much boost etc...

Things like this help to determine. But yes 12-12.5 would be ideal as long as you can keep temps down. On pump 91 I would say this won't happen. More fuel will be required to cool the burn, or a lower ignition advance.

I've been told for my car on pumpgas 1.2 bar with K16/24 around 11.7-12.3

 

I always shoot for mid to high 11's

 

Thanks Guys
