Thread: Using AFR 195's with dome pistons......

Tweet

I've run as high as 12.5 on E85 on the street in a heavy (3700 pounds) car with automatic and air on, still no problems with detonation. The one thing we do that we started years ago on drag cars is to install a small tank (4 gal) and just the cheapy Holley pump as an auxiliary system, with a couple gallons of race gas in it. When you're done racing for the day, turn on the valve from the gasoline tank, shut off the valve from the E-85 tank, and run the car long enough to get gas through the carb(s), then shut it off, through a shot of Sta-Bil in the E-85 tank, and put the car away for the week....

BTW, there is a fuel stabilizer on the market now made specifically for the 10% and 15% fuels, I put a 4 oz shot of it in ye 'ol shop truck (E-85) every time I fill it and don't have any problems with it either.....

Ethanol presents all the same headaches of dealing with it as methanol, just at a much lower cost....Still IMO E-85 is the best way to get away with a lot of compression in a street car!!!!!!

Dave, are you talking about Gold Eagle's new Sta-Bil product specifically for ethanol blends, shown here - http://www.goldeagle.com/brands/stab...ducts.aspx#SET Looks like all three of their non-diesel additives (red/standard, blue/marine, orange?/ethanol) work with ethanol blends, but are earmarked to specific markets. Is there something you like better than the Sta-Bil? I'm thinking that having a bottle in the '33 would be a good idea for those times I can't get to my pure gasoline station.

Yuppers, that's the stuff I use on the street. For the drag cars and Hot Rod stuff I use that and an equal shot of Lucas Fuel additive. On the street cars, even the Bonneville, I use 4 oz. of Sta Bil every fill up just as a preventative. Don't blame it all on the ethanol, either. Remember when all the gas pumps had a filter to catch the last bit of trash from the station's tank before it went in your car??? Not many of them around anymore, either!

Yeah, I remember the filters, and agree they've been gone a long while. I also remember when the ethanol adder was a winter fuel event, and everyone wondered why their mileage dropped when it got cold. Easy answer, less BTU/LB in ethanol compared to gasoline, thus less efficiency. I just wish that we could let ethanol carry it's own weight without any government edicts about adding it to gasoline, and especially without any subsidies on the price of ethanol. Let it float on the free market and it would become a race fuel.

Sorry for the thread hijack, Mohead1 . I'll defer any more comments other than on-topic, even though I learned some things today, and that's a good thing!!
