you will burn more fuel but at 2.XX a gallon it is still cheaper than racing gas. With a properly set up carb you will not have to change the oil that often. 90% of what you hear about alcohol is old wives tales.
Let's just say I don't plan on going back to gas ever.

I'm running e85 and not having any problems.I use about the same amount as gas and its only 2.39 a gallon. The car is a tenth
quicker and 1 mph faster than gas. Also runs more consistant
and cooler. Just another choice

Alcohol turned out to be a big pain in the rear, if you are running good with your racing gas you will see little to no benefit on alky. You have to put additives in the alcohol (upper cylinder lube). If you have an all aluminum block it is hard to keep heat in the motor. Just ask my dad Mike Richter what he thinks about Alky (He has 2 alcohol carbs he may part with) We saw little to no benefit in performance, but there was a lot of B.S. to use it. Now the E85 sounds interesting you might try that if you are looking to save money.
(This was our experience yours may differ.)

I've run alcohol for the last 5yrs and had no problems. Yes I use upper cyl. lube but building heat has not been an issue. That's probably because I run a Rons Terminator and to build heat I just pull the fuel shut off back and lean out the motor. I also use a gas injector to start the motor on cold days. I love it in the hot weather because the motor stays cool. The down side is I only have a 4gal. tank so if you spend to much time in the staging lanes it can be close on fuel. One thing is that when I ran a carb I did not like it.

Definitely go with alcohol. There are several different options here. If you have a carb and rear mounted cell, the slickest thing I found was a Bolaw's belt drive pump. It is internally bypassed so no need for a return line and it will pull perfectly from a rear mounted cell. You can also change back to gas by changing one spring in the pump, mount a gas carb, and put gas in the cell you're ready to go. if you already have a front mounted cell, Ron's injection (toilet, terminator, etc.) would be the way to go. look to pick up anywhere from 1.5 to 2.5 tenths, most all of it in 60'. I maintain my stuff a lot anyway, so I don't notice any "extra" maintenance except that carbureted alcohol will tend to stiffen up accelerator pump diaphrams. Change 'em once, mid season, that's it. Talk to people who have made the conversion. I'd be glad to give you as much info as I can.

Been running alcohol since 1989. One of the smartest things I ever did. Like they say the car is much more deadly and temp doesn't effect your ET's as much gas. The only thing that I have noticed in my cars is that humidity plays more of a factor than temp. A 10% change in Relative humidity will change my cars about .01 either fast or slow, the higher the RH the slower the car will run. But as has been said already it's worth it. I run pretty healthy SBC and both cars have 4 gallon cells, use about a gallon and a half on a 8 teen run. It's cheaper to buy and you really don't have that much issue with oil. I change mine either every weekend or around 12 passes, when I pull maintenance I run the valves change the oil and filter and nut and bolt the car, kind of like therapy for me and it gets me out of the house for a few hours every week. Yes they can be a little tempermental to start when it's cold outside but you learn to adjust to that. We were at the car show this weekend and my Roadster spun over maybe 3 times before it fired and it was stone cold.

I run a Jim Evans alcohol dominator on my dragster. It normally runs in the 4.6 to 4.7 range. This car has won over $50,000 in the last two years with my brother and myself driving it. It routinly goes 100 runs on an oil change and I do nothing to the carb during the year. Sometimes it sits all winter full of fuel and all we do in the spring is start the car and drive it into the trailer. The only issues we have ever had are sometimea needle will get gummed up and stick and we have had heavy floats after a year or so. We do not run top lube.

If you are starting from scratch, a mechanical fuel injection unit is the same total cost as a complete alcohol carb, fuel pump and return style regulator set-up. Fuel injection, either the 8-stack, or the Enderly hat on a tunnel ram is eye candy, and the Ron's units, while not as eye catching also work very good. My first fuel injection was a pair of Ron's 4-Shooters on a tunnel ram with a Hilborn scoop, looked and worked great on my FED.

i have a demon 1050 carb,i was going to take it to c&s in st.charles and have them switch it over,they have a flow bench there,they said i can use my fuel system i have,my fuel cell, and pump,just need to run a return line back to the tank,they said i would have to run a cooler plug,i was reading jeremy and what he says he dont run a top lube,not sure if thats good or bad but must work for him,im no stranger to alky as we use to run jr draster,but im dealing with a big car now

I run a Quick Fuel on both of my cars and have used a Holley, a C&S, a Tom Bannister and a Jim Evans. I also have a Ken Jones Dominator. Out of all those that I have mentioned the Jim Evans and the Holley HP by far worked the best. The Jim Evans piece starts like it's on gas and idles great, haven't touched it since he did for me 6 years ago. The Bannister worked good too but I screwed up and sold it and unfortunately Tom is no longer with us. I had a friend that used to represent C&S and we would go over to test & tune and try different carbs and sizes and never really seemed to get one that worked, would put them on set the floats adjust the idle and the car would slow down 2-3 tenths of a second. Just to make sure it wasn't the track we would bolt mine back on and it would be right back to where it was. One thing C&S does make that's cool as hell is the by-pass fuel log. I would definitely put one of those on your car. |

I would definitely use the top lube. And they are right you go down about 2 steps in plug temp. DO YOUR RESEARCH before you switch over to make sure you get the best you can.
