E85 conversion results
I just converted my Firebird over to E85 with a kit from raceone85.com.It is a 8896 Dominator and the kit converts it to a two circut carb.The car fired right up and idled well after warm up and had good throttle response.I went to the track last night and the car went 9.93@136 off the trailer with a sloppy 1.46 60' in 2000'DA with 100GPP water grains.It was pretty lean with 99 square jets,went to 102 square and ran a 9.87 in worse air.The plugs still looked lean but I didn't have any bigger jets.Third run went 9.90,over reving the 1-2 shift(6800 ouch).I'm pleased and think there is more in it with jetting and timing,also the water grains were up to 115 on the last run.The intake is cool to the touch when the water is at 160*. I paid $2.10 a gal for e85 vs $8.00 gal gr 110 race gas and the car is about .10 and 1 + mph faster in equivalent weather.

On the turnpike here in Orlando.I think there are some stations nearer you, go to raceone85.com and he has a link to stations across the country.There are guys running up to 15-1 on it and I'm over 13.5-1 now.I'm going to fill up my empty race gas drum so I don't have to go chase it all the time.

Just need to locate a local source for the E-98. The math part sucks figuring out percentages and such,by that's just because I've always hated math as SOP. But for the money savings,I can see it being worth a little trouble. Bret P. |

There are testers available. Just tune for 70% and add enough gas to get the "E85"pump fuel down to 70%. Just curious, what if you tuned for 85% and the pump gave you 70%. What would the air/fuel ratio change be at this extreme example? Is there a way to figure this out with just the percentages known? |

Yeah,I ordered mine from raceone85.com ,Heath is a good guy and will help you get it dialed in.It's a few bucks cheaper through Summit,but I wanted to give him the business.

That $2.10 "race gas" is pretty sweet, eh?
I converted about two years ago. There are a few things to be aware of. If you let the carb bowls go dry you will eventually develop some white crud in the bowls. I think this is actually from the water that is in E85 and not the E85 itself. So if you park the car for long periods of time drain the fuel bowls and spray them with wd40. I also run some marvel mystery oil in the E85 to try to slow down the corrosion, and to lube the fuel pump. I know that you know this but for others considering the conversion you MUST replace or coat any steel parts in the fuel system, because they will rust. And you need a healthy fuel pump because you'll use about 30% more E85 on a pass. I have a hard time getting the engine warm, it takes forever now. My performance was exactly the same as on race gas when I got everything tuned out. Buddy of mine running a camaro also switched to E85 soon after I did. They race every weekend and used to buy race gas by the barrel. They have saved a lot of money running E85 and have been happy with it. E85 is rated at about 105 octane, but it has properties that allow people to run crazy compression ratios, or lots of boost. |

yep..i am sure my pontiac will thrive on e-85..i have converted my 12.5-1 sbc vega, and a 12.5-1 383 sbc el camino..works (cant say breasties on here?..lmao)..saves tons of dollars on fuel..throttle response seems better than gas, runs cooler..the savings alone pay for the kit in 2-3 tankfuls..i got my kits from heath daniels also..really nice fella, and seems to know the stuff..i have not been able to do any dragstrip testing yet, but most folks get better performance..even if it equals gas, the cost of fuel alone makes it a winner..nitrous kits are easily tuned for it, and it can be run "fatter" than gas..it runs the same timing as gas..
and it will blend with nitromethane easily.. |

Ok, lets get into a 535 cu.in. 12-1 engine (1150 dominator) with a 82 "nitrous jet" with a Big Shot NOS plate and E-85?
Tune away and see what ya got? |

Just a starting point for this year. 535 cu.in. Actually 11-1 now Worry about this combo later. New combo for next year will be 13.5-1 with a plate. Most local races will be 82 limited nitrous jet..................... but other organizations will be unlimited plate jets. |

That's what the methanol racers who use spray mostly do. Tune the carb on engine only runs w/E-85 and run with that. Simplifies the process greatly. |
