E85 Better with Dual Plane Intake

IDK anything about racing nor about E85. Hmmmmmmm

But from what I do understand, book-knowledge only,the only reason to run an alcohol based fuel is because of it's ability to resist detonation, which comes partly maybe mostly, from it's ability to suck up vast amounts of heat.
By itself, that fuel has less BTUs in it than does gasoline. So it requires a lot more of it, to make the same power.
The thing is, getting any fuel into an engine is usually pretty easy.
Getting the air in is always the hard part.
I'm sure you know all that, but here comes the point;
What if,
that intake was running so cold (he said icy cold), that ice was forming inside it, making the airflow crazy? or lazy? Hmmmm
I don't race, but if I did, I'd want to run a TR.

But here's what I do know;
My street car is a 4-speed 68 Barracuda with an alloy-headed 367 at 10.95Scr and she runs on 87E10. It has a small cam at 230/237/110.
I took it to the track one hot July day, and run it up the track 4 times. 3 runs were a bust but the 4th was as good as I thought it could be. She ripped off, lol, a 93mph Eighth. At 3467 pounds me in it , this translates to 433hp @930 ft elevation.
I thought that was too good.
I didn't believe it so I took my case to the starter booth, and they said no, the timers were working right (they had been having issues which negated one of my earlier runs, the other two being missed shifts on my part). I still didn't believe it, so I went over to the guy that TnTed in the other lane, and he said his time was correct for his car.
So what could I do? Thinking back, I suppose I should have made a back-up run, but that was 2004, and I really didn't gibachit how fast the car was. I was just there to shutup the car show fans who kept telling me I shouldda built a 340.
She runs an Airgap, and the timing was somewhere between 32 and 34 . I never even thought about the "up to 10% alcohol factor" in my fuel, but now that I am thinking about it; hmmmmmm
Another thing I can tell you; is in summer, it takes 3 to 4 miles for the engine to warm up, while cruising at 60mph. I can tell, by when, the car picks up about 4 mph, and I then dial back the cruise timing. ( dash-mounted, dial-back, timing-retard box) Now she's ready to rock!

Anyway, Like I said; IDK the answers to your questions; just pondering while the smarter than me men are away, thinking.
