Hey i just want to know if Using some VP Methanol or a similar Methanol would be beneficial to my setup. I have heard mixed reviews and some Ppl have told me up to 10-15% more power was realized with their setups when they switched over and retuned to use a Methanol fuel. This car is basically just a track toy for me and i dont care about being inconvenieced. I know i would have to switch up my fuel pump and injectors, i also know it is a very corrosive fuel.

My setup:

10.5:1 comp, 81mm X 87 bottom end gsr
Built head
310cc injectors, Gsr oem fuel pump
Puts down around 200ish whp dynojet on 93octane

 

I would look more into maybe a 50/50 spray system. You dont have enough motor or compression to take advantage of that. You're not 14:1 trying to run like 35degrees of timing..

meth injection , might gain you a few more whp by cooling the intake charge. The system's aren't that pricey and can be had for 350-500. The gains vs the price might be close but i'd look into that, worry about full vp meth when you build the motor.

look into 50/50 aka boostjuice.

Go run with the new numbers, although its shitty hot outside lets just see how it does.. meth with this heat might be a good investment.

 

???

 

oh i'm sorry... did you have something to contribute?

 

everyone always says how a 50/50 water/meth never works on a N/A only on turbos, explain that one?

 

Most, turbo guys that use 50/50 usually do it to cool the intake charge, and/or prevent knock.Its a quick bandaid for turbo cars that ping a good bit.. ALOT of Supercharge guys use it, because of obvious reasons. I've personally never seen any real gains from a 50/50 setup on a mild NA setup, but it was a suggestion to try.

Cooler intake temps, denser charge plus a bump in octane rating all are beneficial.

 

The reason why you would run less water on an NA setup is because water really serves no purpose other then extra cooling in the cylinder. It is not combustible, has an infinite octane rating because it does not burn, and displaces air inside the intake system. The closer you are to pure methanol, you burn more "fuel", methanol also has cooling properties as well.

While methanol has like a 129 octane rating in its purest form, as a fuel methanol has a lower energy output then gasoline does. So it would serve you best to run it in small concentrations and see how you go. Remember you will need to retune for it as well, as methanol will throw your AFR's out of control because it is stoich at 6:1 not 14.7:1 like gasoline.

 

Also please remember that anything above a 50/50 concentration makes methanol highly flammable, and when run in 100% form you need to have a properly vented fuel cell to contain it, as the fumes are highly combustible.

 

Was waiting for you to reply...lol

 

 

I think he is asking about switching to methanol period, not meth injection.

You MIGHT make more power but really with a mild engine like that it isn't worth it. You do not want to deal with draining methanol every time you run your car and filling it with gas, then draining the gas and filling with methanol when you want to run. Complete pain in the ***. Try E85 first. There are gasolines that make big power also, but you aren't going to find tons of power on a simple motor like that.

 

You have nowhere near enough engine to warrant a pure methanol setup! Your best bet would be to try some 100 octane Sunoco or E85 as suggested and crank up the timing. Converting to 100% meth would be a total waste in your case.

Oh and Spawne- methanol vapors are actually LESS volatile than gasoline... so no worries there. You can literally hold a match over an open jug of meth, don't try that one with gasoline!

"A certain concentration of vapor in the air is necessary to sustain combustion, and that concentration is different for each flammable liquid. The flash point of a flammable liquid is the lowest temperature at which there will be enough flammable vapour to ignite when an ignition source is applied"

Gasoline -43 °C (-45 °F)
Methanol 11-12°C (~52 °F)

By my understanding, gasoline has a much lower flash point making it much more volatile than methanol, hence much of the reason racing sanctioning bodies have switched to pure methanol.

 

Yes 4Piston was right, i was thinking about converting over to full meth and not just an injection system. But as stated above i was also thinking of retuning on 110 octane and turning up the timing or letting the tuner ultimately decide.. But was not sure race gas could make more power on my setup as well. There a few shops very close to me that sell 110 so it would be less of a hassle..

 

Times will be coming soon! I need every little bit to help get me into the 12s lol.

 

and as you can see, the flash point of methanol is 52 degrees f, which means if you light a match or have a spark and you have methanol vapor venting somewhere in on around your car, you will have a fire. Which is the reason why there is flammible vapor signs on pure methanol containers and the reason you have to have it vented properly when installing it in the car in a contained tank.

 

BUT- gasoline is more volatile with a lower flash point. Therefore as long as you handle methanol the same as you do gasoline (factory venting, EVAP, etc) you'll be just fine.

 

i never said gasoline is more volatile, or less volatile, or anything of the like, i said you need to have pure methanol properly vented because it is highly flammible, your the one who came up with this retarded argument about holding an open flame over a container of pure methanol. honestly, natural selection works far too slowly with the people on this forum.

 

No reason to be a di*k dude I was just having a legit technical conversation with you.

And when you stated this-

"Also please remember that anything above a 50/50 concentration makes methanol highly flammable, and when run in 100% form you need to have a properly vented fuel cell to contain it, as the fumes are highly combustible."

It appeared to me that you were saying Meth is more dangerous and volatile than gasoline, which it is NOT.

 

im saying that methanol is JUST as dangerous as gasoline, i dont understand what your trying to prove here, that fire from a different source is some how less dangerous then others? how do you like your fire?

 

Why not E85? Hell of a lot cheaper with high resistance to detonation.

 

I read that and couldn't help but think about this:

2003 ASCS National Champion Travis Rilat and a crew member were both critically injured in an explosion at a race shop in Washington on Sunday night. According to media reports, both Rilat and crew member Tyson Perez were burned when a barrel containing methanol fuel exploded, severely burning both men.

Initial reports have indicated that Rilat and Perez might have been injured in a stunt gone wrong. A report in the Skagit Valley Herald suggests that the two lit a 55-gallon barrel on fire after filling it with four gallons of methanol and sitting on top of it in an attempt to get a “barrel ride.” The explosion at the Funk Racing in Sedro-Woolley caused one of the ends of the barrel to shoot more than 120 feet from the building.

The ASCS website reports that both Rilat and Perez were transported to Harborview Medical Center in Seattle, where they are expected to spend at least two to three months in the burn recovery unit. Rilat and his crew were in Washington for the ASCS National Fred Brownfield Memorial at Grays Harbor Raceway in Elma, Washington over the weekend. Saturday’s feature saw a serious accident involving former ASCS National Champion Wayne Johnson, who suffered significant injuries to his legs. Ironically, he is also recovering at Harborview Medical Center, where he is expected to make a full recovery.

Rilat is the second major sprint car driver to be seriously injured or killed in a shop accident this season. Rising sprint car star Jesse Hockett was killed in his shop in Missouri at the end of May when he was electrocuted while attempting to fix a short in his trailer. A native of Forney, Texas, Rilat finished fourth in the ASCS National standings in 2009 and scored his first win of the season on July 12 at Southern Oregon Speedway.

 

because not everyone has it readily available, there are no stations in Connecticut that the public can get e85, and the closest to me is about 1.5 hours away so yeah for me I'm not driving 1.5 hours every time I need to fill up other wise I would. I don't know where the OP lives and his access to e85 so I can only speak for myself.

 

I can't imagine it is any less available than Methanol. LOL..

And yes, I was asking the OP not the entire forum.
