Guys,being fairly new to racing GN's I have a question that might be "stupid". Is there a formula to figure out exactly what octane is necessary for a specific motor.In my limited experience I would expect some math that would use ,compression ratio ,boost,timing ,intake air temp,etc to establish an octane requirement.
When I ask experienced people much smarter than me ,I get different answers,all based on something like,"Ive seen cars blow head gaskets using that". "I wouldn't use less than 104, no alky or 93 plus alky is fine",etc,etc.
My car is probably a good example. i have been told ,"use 104 ,wouldn't use less than 110 , better use 116"
Seems to be a lot of seat of the pants or experiential answers. Not that this is necessarily bad and maybe it's me and I'm the dope but WTF . With all the "science " in racing and motors and the addition of computers ,at the risk of being hammered on this board ,I have to ask ,"is there a specific formula for estimating octane requirements for our GN's.Jim Maguire
