Is anyone running methonal on the fuel side of a wet n2o system? If you are, are you running race gas with that or pump and does it make a signifficant difference in power? i know you have to run twice as much meth than gas so is it really worth it? thanks

 

im interested in this as well,someone has to know something about it....

 

IM not really a fan of running the meth instead of race gas.The merthonal is bad about washing the plug and making it harder to read for tunning.Its doable but Its easer to do it using race gas.

I plan on trying some once I get my new Trickflow heads on the ole 355" LT1. I plan on adding a methanol injection kit along with my NX kit and as I jet up the methanol I will start pulling fuel jet on the n2o side to keep it safe. Once I fiqure out the jetting I plan on running the n2o stand alone fuel cell just for methanol if it works properly. Later Clint

 

Like Nitro Dave said, if used to much methonal tends to wash the cylinders and plugs. Methonal injection is used so you don't have to run race gas. Don't use methonal to replace gas in a nitrous application.

 

Let me get this right. You are running a dedicated fuel system with 100 octane just to the nozzle. How does this help?

 

To start with, the result of using race gas for the fuel side of a wet system is no different than mixing an equivalent amount of race gas in the tank. The only advantage is that it allows you to achieve this same result using less race gas. The downside is that you need an entire separate second fuel system. So, I am not a fan of the concept in the first place, though certainly people use a system like that effectively. I'd rather put race gas in the tank and get the full octane of race gas, rather than the somewhat unpredictable result of a mixture.

As far as a separate system to use methanol, there is no reason it wouldn't work. Just as with using methanol in the main fuel system, the system would need to be engineered to supply ~2.5X as much methanol as gasoline. The fuel solenoid, fuel jets, and the lines, etc. would all have to be large enough to accomodate the 250% extra volume of methanol as well. But even more than using a combination of race and pump gas, I think the characteristics of the mixture might be hard to predict. However, I'll hazard a guess and say it would work well. But I can't see a big advantage to it. Cost of fuel would be about the same as race gas (remember, you need ~2.5X as much) and the big advantage of methanol over gas of cooling the intake charge is already occurring to a much larger degree with the nitrous. So, overall I think of this as an experiment not worth trying. But if anyone does it, please post the results.

There are a few cars running straight methanol with nitrous, and the combo works fine. It just requires a suitable fuel and nitrous ssytem to handle the volume.

Why would you need 2.5x more meth then gas? What about running pure Toulene or Xzylene in the tank?

 

Because methanol contains only ~40% of carbon/volume as gasoline. So, you need 1/.4 = 2.5X as much by volume to burn with a given amount of oxygen.

What about toluene or xylene? You mean as fuel substitute? Here's a good place to start reading. http://www.faqs.org/faqs/autos/gasoline-faq/part1/

lOOKS LIKE gREEK TO ME.

 

About 6-7 years ago, I helped a friend convert his nitrous
system to alcohol and we didn't see any gain.

Friday night I bought some methanol at the track and it
was $2.50 per gal. Using the 2.5 factor x $2.50 that comes out
to $6.25 per gal so that prices it cheaper than 116 race gas($9.00).
