anyone ever use race fuel?

o.k.

the thing no one has touched on is the fact...
drum roll please

if you put 1 tank of say 94 (i use)once in a while(like i do)

it will make a differance!(ill argue untill blue or dead).

if like me you use it once in a while.if like when i was experimenting.
one after another..after another... and yet another..

youre bike car what have you will slow down.

unless you car bike ect is supossed to run on high grade fuel..

this is the end of thread.

p.s. i wanted to see how smart you all are!

i am so smart. smrt i mean S.M.A.R.T.(luv homer)

all i'm saying is, for the heck of it, i put the 93 octane in the bike instead of the regular 87 octane fuel. that night i ran twice under 12.3 seconds. the week before i was usually getting around 12.75 sec. could have been any number of things that caused it but it happened. i'm thinking of putting a half gallon or so of actual racing fuel in the tank tomorrow night just to see. then maybe the next week i'll go back to 87 and see what goes on. if there's anything significant i'll post it here.

Just looked up this tiny bit of info.

The guy explains it better than my longwinded version would have.

Hi all, I did run some VP U-4E in my 1150 at one point and I had it on a dyno to see what the difference was between the VP gas and regular gas. It was a little over 6 Hp over regular gas. It did have to be rejetted because the fuel is oxygenated and the fuel is only about 92 octane. It absolutely ran perfectly after the right jetting. And the ignition timing was set at 36 degrees.
The Vp fuel was quite expensive and very smelly as well.

Had you said that these old sleds did not have an ECM to compensate for the lower grade fuels, I would have bought into it. 2 or 4 stroke does not matter. Lean is lean.

Thats the flaw with *@%^$*@%^$*@%^$an's test. Only one vehicle was tested (not a significant sample) and its new enough to have an ECM. Certainly not the case with these old GS's.

Im with ya. Thats just someones info Im sharing. Im not a big fan of running corn gas in my boat either (IO). The cylinders get washed and the rubber exhaust boot dont like alcohol.

So what about Corn gas

When I was a teen in the 70's I remember reading a few articles about damage to snowmobiles from the additives. I even burned holes in a few of my own sled's pistons.

Those old sleds were 2 strokes.



There have been tests done on non-Flex Fuel vehicles to see if they can withstand the corrosive nature of E85 ethanol. Ron *@%^$*@%^$*@%^$en, President of *@%^$*@%^$*@%^$en Inc., an Ethanol plant design build firm in Grante Fall Minnesota, ran a non-Flex Fuel 2000 Chevy Tahoe 105,496 miles almost exclusively on E85. He donated the Tahoe to the Lake Area Technical Institute where it was dismantled and studied. They found that there were no adverse effects of E85 ethanol on the engine or the fuel system. In fact, they reported that the engine and fuel system were in better shape than some vehicles that ran gasoline with fewer miles.

Look, I'm not going to say it's for sure one way or the other.......

but a month ago I was getting smoked by Vespa's on my 450, and yesterday I tried some 93 octane and I blew the fairings off a turbo 'busa.

Not drawing any conclusions or anything, but yeah.....:-D

i put some higher octane in my bike last week to drag race. it took about .5 seconds off my time.

Using one of the billion on-line ET HP calculators that were based on car data to figure out some idea of what your claim is. Lets say your 1000cc L can run the 1/4 mile in 12.5 seconds flat. Say the bike with you and your gear weighs in at 650 lbs. Thats 65 HP. Say you put in that magic gas of yours and you ran a 12 second. Thats 75 HP or a gain of 10 HP or way more than 10%. That's huge!

The stuff most of the companies used was MTBE. Thanks EPA for looking out for us there.... Whole idea was to reduce emissions but I am guessing that the effects of MTBE will be with our kids kids kids.

Maybe I missed something, but adding Ethanol to gasoline is not increasing BTUs. Pure Methanol for example has far less BTUs/lb than pump gas. You can get more power out of it because it needs to burn at about 2X fuel air ratio of gasoline. The big reason to use it is not for this little gain in power but because the stuff is very stable. Ethanol is the same. Adding it to gasoline is going to lean things out. Newer engines can adjust for this, but older carb engines can't and they will run leaner.

When I was a teen in the 70's I remember reading a few articles about damage to snowmobiles from the additives. I even burned holes in a few of my own sled's pistons.

Leaner is quicker until she melts.... Maybe in your case you just need to jet it down a little and forget the fancy fuel....

If you want more power, I suggest getting a bigger bike.
Oh, if you could only convince people of this.

Yea, you have heard of a Horticulturists? There is an old saying...

"You can lead a Horticulturists but you can't make her think!"

In a stock motor designed for regular gas you mostly spend more money and dirty up your oil faster. That has been my experience thru 4 bikes...

it was oxygenated then... otherwise i'll have to call BS

Higher octane fuel will actually slow down the burn and cause slower times..

[brveagle]

the only race fuel that might make a differance would be some of that oxygenated stuff, that you have to buy in 5 gallon metel barrels.

other wise don't waste your money for street riding.

Very correct. Higher Octane fuel will only make your bike run slower. Period.

End of thread please

ill agree!

with ms.s. there ill put 94 oct.in my bike it will run better(and go through the gas faster) than regular petrol. faster? you bet you can feel it.thats just 94 vs.what 84(is that the norm or what ever is the norm.)
bye vrrrroooossssssshhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh hhhhh
