Throw out your intercooler!

[DblTrbl]

I was at the NHRA Sport compact race at Englishtown this weekend. The Pro Neon with the most humongous turbo does not use any intercooling, only alcohol. They said that they tried it with and without the intercooler and it made no difference, so no more intercooler. Wow!

[GLHNSLHT2]

what are they running for fuel? I guess if you throw in enough alcohol for cooling it wouldn't make a difference. Some of us don't have the time to refill the bottle though

I'd use alcohol in my Omni but I'd be too temped to tap into the reserve.

thats why i dont use no2, it would go into the passenger compartment instead of the engine

Alcohol does not detonate, and if it was an alcohol only car, there's really no overwhelming need for an intercooler.

[DblTrbl]

I think it was alcohol only.

trivia time: do you know why this would not work????????

answer: any nitrous oxide sold to the public, that is not for medical use has a little something extra added. Sulfur Dioxide, commonly refered to automotive grade nitrous oxide, or Ny-trous Plus. Its harmless for our use, but if you try to huff it, it will make you VERY sick, VERY quickly. I mean throwing your guys up sick! I caught a quick wiff of some nitrous when changing bottles one day, and that was enough to make me sick to my stomatch for a few minutes.

Alcohol rocks!!! I'm guessing in the next few years, there won't be a modified turbo vehicle around that won't be injecting in. (once the word gets out about it)

[beefalobilly]

maybe even on the street with gas prices going like they are

been there, done that. Car ran great got 80 miles to a TANK of alcohol. I now have methanol injection.same benefits without running on methanol all the time. As my screen name implys I am a methanol junkie.

Ill stay cheap and stick with my intercooler for now thank you very much.

I think some of you guys are misunderstanding Carl. The car he is talking about does not use gasoline as fuel. It uses alcohol. This is not a gasoline powered engine using supplementary alcohol injection. It's primary fuel IS methanol alcohol.

[turbometh]

For a race only car methanol is the only way to go. Carl is right methanol is by far a better fuel. People get scared of it because it is different. Once I was subjected to it on my sprint car I have loved it ever sence. High octane, cooler intake temps, cooler running engine and more oxygen. However safe a/f ratios are around 4.5 to 1 so you use alot more of it. I use almost 20 gallons in my sprint car in a 25 lap feature on a 1/3 mile track.
When I ran my TD on methanol I installed 75 lb injectors and played around with fuel pressure. The car ran great, had awesome throttle response. Started hard when cold.
Methanol is also very corrosive. You have to clean the fuel system regularly and run the correct fittings, etc.
My methanol injection takes the place of extra fuel under boost. I unhooked the vacuum line to the fuel pressure regulator which made it run very lean. Then used the progressive methanol injection to add the extra fuel.

[DblTrbl]

I run 52lb injectors for gasoline and four 3.6 GPH alcohol misting nozzles, one into each runner. The alcohol comes on at 12PSI of boost. The alcohol is on full blast only, so I tune by reducing the amount of gasoline.

Carl-- Do you know what a/f you are running. I just got my injection kit and have not had time to tune it with my wide band. I know what my sprint car runs at but the TD aint no TD.
