You are right, the higher net octane rating of the ethanol blend should reduce pinging, however, you need twice as much ethanol as dino-gas per part of air to make the same power. As you richen the A/F ratio, it gets into an area where the dino-gas fouls the spark plugs, runs rich, wastes gas, while the ethanol still burns WAY too easy resulting in pinging. Its kind of a lose lose situation
I am running a carb, but fuel injection can lessen the problem's noticeablity somewhat though itll show much lower power on a dyno.
For a little while I was running straight methanol, and the major problem was procurement. When I could get it, I got it CHEAP, though it seems, unconventionally and was forced to stop getting it from the subsidized depot (apparently if we form am "organization" my friends and I could keep getting it legally, but it seems like paperwork nightmares).
It was eventually pointed out to me that I really was doing the environment no good from the supply end, as dino gas had to be used to make it and move it around. However from the useage side, a couple of trips through emissions (the way I normally tune my car anyhow, 15 bucks a sniff) and the output of the car was near zero on any of the tests they normally do. Not that it doesnt make some nasty pollution they dont check for I dont know
The only mod I had to do was run hardline from the fuel cell to the carb, and change my fuel pump and fuel filter gaskets from rubber to phenolic. I had to kiss goodbye to my beautiful bradied hose fuel line but whatever.
From a driving standpoint, I get 12 degrees initial timing with dino-gas, 20 degrees with methanol. Driveability and throttele response on the low end go through the roof. No pinging even in the hottest Phoenix days. On the dyno we were able to get WAY more of the dyno horsepower numbers to the street, 385hp dino gas to 425 hp methanol, which is still a bit shy of the 450-ish hp we could get on the dyno but not in real driving, but a lot closer
Now summer's coming up, Im on the 15% whacky juice at the pump and bumming, please someone come up with a way of making methanol cheap, available and green
