Cooling effects of E85 vs non-E 100-116 octane
This is what I use for adjusting stoich based upon ethanol content I'm using...
(9 x alcohol% as decimal) + (14.68 x gas % as decimal) = stoich
For example with 50% ethanol and 50% 93 octane I use 11.84 as my stoich. If I test and know my alcohol content and use this formula to change stoich my fueling is always very close.

This to me seems like a ton of extra time and money to use a fuel that seems only slightly better than a fuel like C16 that will also get you where you want to go.
The E-type fuels may cost less but factor in the added required components, time for travel to get the drums, the hassle of moving the drums, mixing/testing the fuel and for how little you may be running that car at that level seems C16 would be a break even and require only an additional tune.

you do consume a lot more fuel with ethanol but the delivery fee on a drum or two a year aint bad. I'll go though 1-1 & 1/2 drums per season racing 1 night a week.
for me one of the biggest benefits is actually pretty silly. ethanol exhaust is barely noticeable. gasoline cars with out cats absolutely smell like **** to me now. My daily runs on pump and working on it or tuning it is a total bummer to the point I neglect the hell out of it.

Meanwhile I'm over here
We raced the same blower car at 30PSI with F1X on Q16 and E100 and currently run it at 35PSI on E100. The Q16 was great but got super expensive ($1,000 plus a drum) and got harder for us to get. Q16 also makes the plugs look different than most people are used to. We ran the same A2W intercooler with both fuels and run cooler on E100. The E100 is not as picky on AFR as the Q16.
We have another blower car we run on C16 and it likes to be a lot leaner than our E100 and Q16 cars.
Anything we race heavily if it runs E we only race it from E from a drum. Its just always consistent and we know what we have. If its just a street car then we do flex fuel setup and use pump E.

When I told him Ignite Red's last year price was $450 for a 55 gallon drum and that included $35 for shipping he became very interested. That is about $8 a gallon. Ignite Red is E90, 114 octane. He said he thinks a 55 gallon drum of C15 is like $1200.
