Running methanol mix for drags?

[Gttwinturbomk3]

Hi there everyone,

I am wondering if many people on here have chucked some methnol into there tank with fuel say 10-15% mix and noticed a significant increase in performance? I am thinking in theory if i put 4 litres of methane with 20 litres of 98 then it should increase to about 110 octane straight away and run cooler with out any worrys, good fuel for at drags maybe and help prevent pinking at higher boost levels? Good for higher compression NA engines too. Just as a one off, one time thing not continuously running.

Or even running E85 for drag purposes?

how will you tune for the extra X% of fuel needed? how will you change timing?

It would involve a wee bit of dyno time obviously, checking the mixtures, put bigger injectors into it, adjustable fuel pressure regulator to set fuel right, and concentrate on the o2 readings from the apexi unit. In the case of my 1ggte with 14psi.

prob not right thred but op might be interested anyway

anyone know how e85 compares to say a u98/toluene mix?

Quoted for truth!

If it were me I would take advantage of the properties of methanol by using it as a charge cooling/octane booster by spraying into the intake pre turbo or pre throttle body if NA. Put in a ratio of somewhere between 10% and 30% by volume of the fuel your engine uses at WOT and advance the timing and or boost it up!

E85 requires something like 33% extra by volume compared to regular gasoline, and most aftermarket management systems could be given a 2nd map to select when running it etc. A lot of new European cars have intelligent ecu's which use sensors in the fuel tank to determine what sort of brew the owner just dumped in and run a tune to suit! Doubt it works for diesel though!

Cheers,
Jason

IMHO i wouldnt mix methanol with petrol because even though methanol is high octane is doesnt automatically bump up the octane of whatever you mix it with(thats toluene and another story) Methanol can be very effectictive a chemical charge cooler(done it myself with a big turbo diesel) but when used as the primary fuel needs to be injected in huge quantities comapared to petrol. that doesnt compute with using a small quantity of it as a booster in normal fuel.

Did this, don't recommend it.

what is stoimetric for methanol?

i read somewhere that top fuelers run a 2:1 mix of air and meth

[Casey-G]

something like 6.4:1 andrew

Actually that 'meth' you speak of is mandated by ANDRA to be minimum 80% Nitro Methane in a top fueler hence the 2:1 fuel ratio!

ah cool. thanks for the clarification guys.

i love seeing top fuelers in the flesh. there is nothing to compare to the mechanical awesomeness of those machines. cant wait til they finally come to melbourne for motorvation in a couple of weeks

For the sake of clarity, it's the Top Alcohol cars which run on methanol. Top Fuel is nitromethane.

clarity galour.

Hi Guys, As someone who is an x speedway racer mixing these two fuels as raw fuels WON'T work, as the 98 octane is a oil base fuel and the methnol is a water base fuel, If you put the two into a bottle and put the lid on and shake and let settle come back 5 min later the 98 will be sitting on top of the methnol. So it's ether, all or nothing,
Methnol motors use about twice the amout of methnol as a petrol motors
Hope this helps Tony

what if you add acetone(?)

for example "heet", 99% methanol and 1% "proprietary additive" (to remove water in tank but.. makes methanol and fuel "mix"

or is it benzene?
http://www.patentstorm.us/patents/43...scription.html

benzene, toluene or xylenes and an alcohol having at least 3carbon atoms chosen from cyclohexanol, propanol, butanol, amyl alcohol or hexyl alcohol

The stabilized mixturesobtained in the Japanese Patent Application contain 10 to 30 parts by volume of methanol, 0.2 to 3 parts by volume of alcohol having at least 3 carbon atoms, 5 to 30 parts by volume of added aromatic hydrocarbon, and at most 0.35 part by volume of water,the mixture being supplemented to 100 parts by gasoline.

edit: not straightforward...
