uses alot of fuel compared to gasoline. harder on carbs, remember it is also corrosive. cheaper to buy than racing fuel.

Thanks x13jc. I didn't know it was so corrosive. I also need to know what fuel pressure, what jets and all of the internals. I have run the car and only got it up to 130temp. I have been told that the richer you run it the less it will heat. I have had to change my oil the last three races because I have had too much meth in my oil. Thanks again. sideways34

Well, try this out for size. Take a yard stick, stick it in some methanol, just for a second, and see what happens.
We run a 160degree thermostat, with 2 holes drilled to stop vapor lock. As long as the temp outside is not 90 or better, should keep car around 180-190 degrees.
I run ours fuel pressure at about 9lbs, 6lbs warning light.
After running a race at night, you should flush the car with gas.
We use a synthetic blend oil, or pure synthetic. Change it along with the oil filter every 4th race.
Jets you can play with size wise. That can bring the heat up also. If you lean it out too much, you are asking for alot of trouble.

We found one of the problems, if not the biggest problem. We tore into my carb, and found one of the floats had a crack in it. The float filled with meth and sank to the bottom. It allowed the float bowl to fill up to the brim every time the car was started. The fuel was pushing past the needle and seat, up through the vent and down the intake. That was where all the fuel was comming from in the oil. Now we have a starting point, and we can get started on getting it fixed. thank you for all the info and I will put it to use. Sideways34

make sure u are running size 10 fuel lines
if u lean out under power ull burn the motor down with methanol just take plug readings till u get it dialed in right and dont be suprised when u let off going in and it goes poof and blows flame alcohol does that a lot more than gas

Thanks guys. I ran the car last weekend. I got ahold of a speedway book and went nuts. I ordered about $300 worth of fuel system stuff. The guy I bought the car from had pipe fittings and fuel hoses for a "fuel log". I bought a new fuel log and pressure relief valves. I went through and put brand new fuel lines all the way from the cell to the carb and back. I went through the carb and found the float, power valves, needles and seats, and gaskets, were all bad. I also found two of the four jets laying in the carb. I fixed all of that and the car ran like a champ. The #3 national pionts driver came up for this race and I couldn't run with him, but He didn't run away from me for about two laps. I was happy with the performance of the car, until the second night. I ran into the back of a car that was out of control and jumped on the binders. I tried to go around him, but clipped the rear of his car and broke my steering box and bent the center link back under the cross member. Not to mention that I lost oil pressure and couldn't start the car anymore. gotta go. sideways

We run 90 jets in the primaries and 96 in the secondaries. We ran it and the car only got up to 180 but the outside temp was55-60 so we will run it and see what it does. The season is over up here and I don't have enough experience to travel, so we are hanging it up till april. thanks for the help. I will still check this page so if you can help through the off season I will be here. thanks sideways
