Ok little nervous about making the switch. I have been running nitrous a few years now. Use roughly 240 lbs each season so have a little experience.
Question about start up tune.
Is timing the same as 110 race gas? Do you pull more timing? What do you target for afr on you start up tune?
Also I run dry with Holley EFI. What's a decent fuel lb adder per 100 shot?
I hear plugs are hard to read. Are the heat ranges similar to race gas. For example I am running an 8 range on 200 at 22 degrees and get some heat on the fist thread.

Thanks

 

Hi, what is your area, the city, the state ?

The "E" content of the fuel you ask about is LEGAL to be from 53% to 85% Ethanol.
The octane is rated 100-105 as common.

The 110 timing question, use 100 Unleaded Timing.
Best bet, make your OWN E-85 to E-95 for track use.
