This might have been asked before, I searched, found nothing.

Anyway... I know thier not legal to use in most classes. But I was wondering if someone could explain the process of making it and what exactly it is. I know its normal race fuel, with a higher oxygen rating? So whats this cause? Its to burn better ??

Also what do they add to the fuel to oxygenate it? I know you can add some chemical to normal race fuel to bring up the oxygen in it.

Thanks... just curious to how it all works.

 

The only oxygenated fuel i know of is methanol and it just comes that way, never had to mix or add anything to it. I never heard of any gasoline that was oxygenated.

ELF GAS.......

 

i use it in my 03 r1 for the track, 80bucks for a 5gal can they say you gain 10hp just off the fuel in a 1000cc bike

but its only 107 octane

 

MTBE is an oxgenate additive thats in many different fuels including pump gas.

VP MS103 unleaded has it
VP U2
VP U4
VP CMP
VP DRT
VP MS109
VP CSP
Propylene Oxide (add this to Alky/gas/nitro) adds so much oxygenates its like Nitrous! Fuel mixtures normally have to be enriched by 5%

you need to get a VP fuel catalog...they have a bunch of different fuels that are oxygenated...

im goin to try the cmp fuel on the dyno next week versus regular 100 octane fuel

So adding this to race fuel would increase the power ??? what kinda ratio do you add it at? Again, im just trying to learn about this stuff, I heard someone talking about it, and didnt quite understand it...

 

im using CMP wich is like fuel you dont have to mix it or anything...
ill let you guys know how much horsepower i gained or lost

 

OK a bit of searching and Ive found what im looking for....

I found this info on http://www.worldwideracingfuels.com
it says you mix 1 quart of Propylene Oxide for every 3 gallons of fuel... and no timming changes and it increases your HP by 8%....

Now id be very intrested in knowing if it really does work

And yes I do relize its illegal to do in most sanctioned events.

when the all motor scene first started everybody and thier mom probably tried it...but i never heard of anybody making gobs of power from it...plus i heard its very corrosive

 

see I have heard this aswell... I was just curious to what was being done... no need to cheat, or break the rules, I belive in fair racing... where it comes down to legal mods, and driver ability.

 

from an engineer michael woked with when it was legal to supply your own race fuel in F1.

propylene oxide's primary contribution to the combustion process centers on it's high heat of vaporization. this high heat of vaporization means that, as it passes from a liquid to a gaseous state after the injectors, it absorbs a significant amount of heat and, thus, cools the incoming fuel charge significantly, making it denser.

it's combustion products are CO2, CO and water vapor. it should be noted that propylene oxide brings along some of the oxygen it needs for it's own combustion,but it also takes additional oxygen from the area beyond the injector in the intake tract. it's specific energy is slightly less than that of race gasoline, so don't expect any help there.

propylene oxide's threshold for detectability in race gasoline is 2% and you will see no measureable performance difference between a baseline racing fuel and a sample containing 2% propylene oxide by volume
. however at 10% by volume, well above what a tech man should be able to spot, you will begin to see the effect of improving the charge denisity on the low end of the rpm range, but this effect diminishes as rpm increases, becauses the higher air velocity through the intake tract dramatically improves the atomization of the gasoline and the resulting chilling of the incoming charge."

michael would like to add that there are additives that will increase hp dramatically when used with gasoline, we will not disclose those additives so please don't email me for them, but he would like to stress that do it yourself fuel chemistry is dangerous. so unless your a PhD chemist, or have access to sophisticated testing facilities, the chances are that messing with your fuel will only make you slower, increase the likelihood of damaging your engine, and get you bounced in tech.
the people who really know about fuel are the people who do it for a living; the oil companies in their racing divisions, and the professional additive manufacturers.
trying to out think them is a fools mission. there is almost no likelihood of you producing any kind of fuel coction that will perform better than high quality racing gasoline.

Fuel additives are a waste of time.....

run gas from 76 or sunnoco or VP that is oxygenated

me I like like good ol 76 100 octane unleaded seems to make really good power

 

who's michael and why cant he write up his own post's?

Thanks... very good info... and im not trying to fool anyone. I was curious to what exactly propylene oxide did. You answered it perfect. Again, im not lookin to " fool" the tech people, I Was curious. I had heard about it a few times, but really never knew what it did. So what better place to ask?

 

ed,
the michael i write for is michael brennan. he is the ndra's national race director.
i monitor a number of forums for him in order to stay current with what you guys are interested in. other posts i have written address this matter more in depth, please see those if you need more info.

ive ran nitropropane from vp . Really need to ramp up fuel pressure to make it work. I used a 5% mixture and an extra 10lbs of fuel pressure.

 

damn seems like there is alot out there, i never even considered swapping fuels. Since we seem to have quite a few guys with some fuel knowledge heres a questoin i have been curious about. I have always run C16 as long as i can remember and this year ill be switching to methanol in my turbocharged integra. The question is this, is there any differences in the manufactures of methanol. I see that it is 99. somethin percent pure but can anything effect performance between say VP anbd Sunoco brands or is methanol the same no matter who you get it from?
