methanol

[krazyhorse]

i am planning on converting my 1050 dominator over to methanol. my question is what if any thing will i have to do to my tune up. in regards to timing, plug heat range, and fuel pressure. and would i have to change my nitrous set up. nitous runs on 116 race gas. also can someone tell me why johnny barb runs his nitrous bottle upside down. i know i have a lot of questions but the only thing that i know about alky is you need twice as much fuel, and the enigine runs cooler.thanks.

please can someone answer these questions or atleast give it a stab? I traded my carb & fuel pump last night for an alcohol carb and aeromotive A2000 pump and would like a starting point to begin tuning.

I would like to know where to start on the base tune as far as fuel pressure, timing ect....

I was running 6# and 36* with 92octane fuel.

also how do people run nitrous? can i still run an aux fuel cell with some 116 in it for the nitrous system. or do i have to switch over to meth on my fuel side and get a new solenoid?

I figured out the nitrous question by calling NX. he said running an AUX cell with race gas in it just like before works great for spraying nitrous with an alcohol carb and they do it that way a lot & that the alky helps out any detonation issues of the N2O significantly.

I've ran methanol on my dirt track cars alot.In a back to back test one motor made 604hp on alcohol and 575hp on gas.It is a real dry fuel I used the stuff with a lube added to it. If the car sat very long I would fill the carb full of gas.A lot of people will say you have to run real high compression I ran a motor at 10.0 no problems ever.You can get real rich before it hurts power but becareful it will start milking the oil and washing down the clyinders.Timing and fuel pressure is the same as gas.

[John_Heard]

Most of the people that I've seen run it successfully use gas in the nitrous side, that seems to simplify the flow issues vs using alky on both engine and nitrous fuel systems. You would have to jet up a lot on the nitrous side and perhaps change/add fuel solenoids to get the flow rates needed on the nitrous.

the motor is 10.0 so it good to hear it worked for you. desk top dyno picked up like 22hp and 45tq so we will see.

what did you do with you plugs as far as heat range?
What do you guys do to build heat? i let it idle for like 10 minuets and it never got above like 110*. I know its running rich and needs tuning but dang

drill a hole in the intake, install a valve like a drain petcock open it to make a lean high idle to build heat screw closed works good..

X2 and get the engine to atleast 220* so you don't have the milk shake oil. I run mine up to 220 and hold that temp for about 2 or 3 min, shut down and heat soak the engine, do the same again and shut it down. Once I have done that, the car is ready to run for the evening. Then after I'm done for the evening I'll heat it up one more time to 220 - 230 and shut it down.

thanks for the replys, i'll try to rig something up on there & see how it works.

The only thing I know about running E-85 is the jets have to flow twice the fuel, so mathamatics say a third larger jets, you must also increase the air holes to match, as more fuel requires more air.

[racecar100]

You also need cooler spark plugs to run on Methanol

[lightnin]

you dont have to take out near the timing on the nos side either

[Racer704]

Dadnova E-85 isnt methanol its a blend of 15% gas and 85% ethanol. Also E-85 will make close to the same power of methanol without all the headaches of 2 fuel systems and having to purgwe all the meth. out so it doesnt attack parts and you dont have to change the oil so offten.

Gas a enrichment on N2O side with methanol is great and its done so you get more of a complete burn of all the fuel. Its like a blasting cap for fuel.With E-85 out there in the service stations I see no reasons to have to mess with methanol.

E-85 runs about 30 to 32% richer and Methanol you need close to2.7 to 3 times the amount as gas.

E-85 out of the pump is about 105 octane. Look at VP's new methanol on there site there bragging how it makes 50 more hp then before. Any guesses as to why? There is a hydrocarbon in it now to help ignite and burn it more completly.

I am not knocking Methanol as I used it in the late 70 and early 80 on the street with my little 340 Dart. I always had a friend carrying 2 to 3 5 gal jugs around for me...lol Made my own carb and sprayed the hell out of it.

I use E-85 now and it picked up 50 plus on the dyno over 118 NOS supreme. Its easier on parts and timing and loves nitrous.

Go to www.O2technologys.com and read up on it. Thats Ricky Dyers site with his son and look at there little motor on the dyno with E-85..

i run aprox 34 deg timing (locked out)
i have a mec fuel pump 3 lbs idle aprox 10 lbs at top end
i talked to the people at aeromotive when i was going to change pumps they said you should run a bypass regulator
when your done racing for the day get it hot and shut it off pull the breathers for a while to let vapors out then put them back in later
found valv oil works well with alcohol but just my opinion

[Stickshifter 55]

Speaking of methanol, has anyone used the VP M3 or M5 methanol? I wouldn't mind making more power. I need to buy some for this season and I haven't don't too much research as of yet.
