My curiosity is can I get away with 101 gas with either of these pistons? It would be nice to have a 14:1 especially when you are up at St.A's because the elevation is right around 5000 ft. I am thinking the next mods are going to be bigger piston, Full pipe (probably RWR) and TVI Race head. Either those or I wil jsut splurge and get a 760 or 830 Pami![img]i/expressions/face-icon-small-happy.gif[/img] I am also working on another trick up my sleave, Bullwinkle!!??[img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-tongue.gif[/img][img]i/expressions/face-icon-small-smile.gif[/img]

 

Thanks for the info but I think I will just run a thinner copper gasket and get it up to 13:1 I should be ok at all elevations with the 101.

 

how much does the power change with the higher compression? say from11.5 to 12.5
