Anyone running 9.5CR pistons with reflash and pump gas?
What charger, rpms and boost are you running? 93 octane?

No octane boosters, 50/50 mixes, av gas?

We have been lucky at our local airport....AV gas has been $5.10-$5.50 a gallon.
I run a old ET 68/140 at 9,000 rpms on CP 9.5's depending on the air it will make 16-18lbs

Risky IMO not knowing what timing your running in the actual map and what kind of fuel your getting at the Fl pump. Some ICs run much better AITs which makes a huge difference as well.

Wouldnt a higher ethanol content be better for a high compression/racing setup?
E85 is supposed ti be ~85% ethanol
I always check my afrs everytime i go out and can adjust fuel pressure if the readings are off for some reason

The higher the ethanol content the leaner it will be, if you usually run tuned on straight 93 octane(non-ethanol). It only take a split second to damage piston.

I shot for very low 11s and high 10s on e85. Energy potential in it is great but good gawd do you burn through a tank FAST. You'll need a high output and reliable pump too.
