195lbs Compression- What Mix?

[IcutMetl]

Using one of the thin portions from the disassembled head gasket, I'm getting 190-195+/- lbs of compression; 3 different tries. I can get Cam2 110 locally; what mix of that and premium do I need? 75/25 or 50/50 to be safe??

Coming from a .020" bore, no porting, and 155-160lbs to .060, ported, and 195lbs, it ought to wake up pretty good I would think. It's a lot different to kick; I can tell ya that.

Thanks, guys!

race gas or at least 50/50 mix race gas pump gas @ 32:1

go straight 110. a little security is worth the money.

I am running 215 lbs and run 110 and going to switch to c-12 . I think you should run straight 110 in my opinion.

well i run 93 i have 200lbs. comp an it has not changed in 3 years. an i i let it rev like hell

if you are bumping out 200 on a snap on gauge and running 93. you are really missing out on the potential of the motor. when I first got in to high compression 2 strokes, a banshee I did the same for 2 years and the day I sold it I ran some 110 and man what a difference I was blown away. I would be surprised if you are running 200 lbs. and running decent on 93, just don't work that way.

me personally i dont see the point with race gas... to me i dont gain enough hp to use it.. i'm goin to pump gas...

but to the first question i would run 100% 110...

The race gas doesent gain hp on low compression engines. When you start to build high compression engines 200+ 93 octane will pre-detinate and burn a piston. Race gas has higher octane that that keeps from detinating. Compression=hp

50/50 mix, or 100LL aircraft fuel would be perfect for that.

as long as it isn't oxygenated fuel. also, some aircraft fuels have lubricating detergents will not burn well with 2-stroke oil mix.

ive heard of plenty of people who have gotten away with it and it didnt hurt a thing.
