100 av gas

[adirondac blue]

Can I run this gas straight and what boost level is it safe for, 8, 10, or 15.Stock motor with cpr turbo.

octane

your stock motor is 11.8 : 1 compression

so running 12 lbs boost will require 100 octane fuel @ sea level.
and bring you boost compression to 11.8:1

13.5 lbs @ 3000 Ft
15 lbs @ 6000 Ft

Remember that these numbers are @ wide open throttle.

Prolly 10lbs for normal use.
U can always mix with pump premium to get lower levels

I run 100 percent 100 LL avgas in both of my turbo sleds ......better safe than sorry .........9psi w/ the Simons cpr turbo and 11 psi with the bender turbo .......both have the 0.54 headgasket.

I ran Sunoco 100 race gas and 12#'s with .054 head gasket last year on my McXpress front mount with zero problems.
