So it broke a ringland, but never did anything bad? What broke the ringland?

Ive ran it for a good while on car in sig made 800 on our mustang dyno, price wise cant beat it cost me $15 to go racing instead of $75 for C16, hard to get myself to jump in the car at C16 prices but dont mind going out and beating on bikes/cars with $15 worth of fuel in the tank.

I think Im using so much of it though, that its eating the oil up quicker than what you would see in a flex fuel daily driver putting around. I had 100#s at 100% dutycycle at 80 psi base pressure, now have 220s hosing down the intake

WHat kind of timing/cyl heads are the guyss making 800-1300 flywheel running?

 

Sounds like it was the tune, not the E85.

We just pulled apart LS2Formula's car that has been run exclusively on E85 and made over 100 passes at 7.9 to 8.3 in the 1/4 mile. With the exception of the damage from the cam bolts breaking off, the motor looked brand new inside. All bearings were perfect and the cylinder walls had perfect crosshatching.

 

106 octane for under $2.50 can't be beat. Low Availability is probably the biggest drawback.

Methanol injection with 91/93 octane can grenade your engine if the meth pump fails.... This is one less thing to go wrong.

Just need the larger injectors and more fuel pump as noted. Flow 30% more.

Luckily I have it in the same town that I work in. Better than $10/gallon+ for 110+ octane.
