highest compression on 91 octane

[tecateboy]

i was wondering if anyone knows what the highest compression i can run on a stock A1 tecate with 91 octane pump gas?

i just cut myself a new head gasket out of thinner gasket material than what the one thats on there is made of and i dont know how high it will raise it, and i just want to be safe.

In wisconsin I'm assuming your at 0-3000 ft. I believe you can get away with 120-130 psi.

how do you make a head gasket?

having a thinner head gasket wont raise the compression enough to make it unsafe thats for sure if thats what your askin also make sure that its well made with the right stuff !

yeah, gasket material is not the answer, maybe for a base gasket...

ohh, i was thinking it would hold cuz i have gotten a head gasket from a gasket set that was made from the gasket material...so i was thinking id do it for myself and try it.
