I am considering making two changes over the winter.

#1

I am seriously considering converting from race gas ( VP-C15) to methanol not just because of the ridiculous increase in cost but primarily to improve the consistency.

I am interested in hearing from guys who made the change, what are the advantages and disadvantages.

#2

The second change I'm interested in researching is converting from a conventional Biondo CO2 throttle stop to a under carb electric stop, like a #1 Stop.

If you are going to run methanol I would run this methanol ^

Bob,

If you haven't done it already, study & ask questions of consistent winning racers in your class or classes you run. Then figure out the most used throttle stop/fuel being used to win.

I'm a huge studier of racers I consider the best in my class/classes I race. I also like to try & race the best; IMO that's the best way to learn. That's I why I like the Spring Fling Million races. Overall running the Spring Fling races has upped my racing skills immensely!

I went to alcohol in 1998 and thought I would never go back to gas. I was forced to on my last motor simply because it ran better on gas. So I sold that motor and going to a blower motor on alcohol.

I believe alcohol has been one of best things I have done in racing, it runs cooler, consistent and cheaper.

I have tried several different big name carbs and right now I think the best out there is the Get'M twin blade but if you are going to use a restrictor plate or throttle stop do not think they work well with the twin blade deal. They do have standard 4 barrel carbs and they may work good, just do not know. Injection works well with alcohol.

I will not comment on throttle stop as I do not use them.

Answer to question #2

After a little research I came to the conclusion that the #1 stop was not going to work on my car, it adds 2.75 inches of height, won't clear the hood scoop. Not changing the scoop and lowering the engine adds more challenges and expenses than I can count.

Question #1

Not wild about the additional maintenance required with alky, nor the corrosion it creates in the fuel system. If there is a simple, relatively quick method of stopping this (tank, fuel lines, regulator and through the carburetor) I'd like to hear how that's done effectively.

Note: I live and race in avery arrid (low humidity) but high heat part of the Country so I'm aware that running alcohol/methanol has advantages. Reconstituted alky is the challenge here, it's not always pure (or lower than .01% water content).

Thanks for the suggestions Bryan.

Bob, my experience with alcohol is that the problems are over blown on the net. That said, there is always the possibility of problems with it. I don't do anything special other than running Klotz top lube. I race, fog my engine with Foggit, and put the car away. I may go 2-3 weeks between racing and the car sitting in the trailer and no problem. Been doing it for years. One thing you are going to notice is the extra torque so stop settings will change.

Now on throttle stopping a methanol engine I have zero experience. I wonder about the amount of fuel used causing puddling on the stop though. Pauley on here is making this change right now. Might be some valuable info in the thread for you.

Gday Curtis,
If you dont mind me asking what ratio of klotz are you using to a 44 gallon drum, full bottle or half?
Cheers
Paul
