Race gas vs. Pump gas
tma...@aol.com
O.K... I have heard the recommendations, I have made recommendations (to run race gas), I have heard people out here that
say it doesn't matter. To those who say it doesn't matter, I say B U L L S ___!
I have (for the past year) run either CAM2 (Sunoco race fuel) 112 octane or FASS GASS 116 octane... This past week, I didn't have time to get race fuel and hit a Sunoco 94 pump. Let me tell you...
It SUCKED! (I run 36:1)
The 50 lost power, ran lean (I had to rejet) and DID NOT WIND OUT like with race fuel. The 60 and 80 spit and sputtered and smoked like frieght trains.
I have already drained the gas and I will definately be running to the dealer for race fuel, but I thought I would let you all know... If your a Race Fuel Adict and your bikes are jetted for it...
You will not like to go back to pump gas!
Also... I have tried Torco which is alchohol based race fuel. I didn't see a big difference between the Torco and the Cam2 that we usually run, but the Torco is cheaper and they are really into
trackside support and sponsoring locals. FYI.

I will quickly tell you my story.
I have always used Sunoco 94 pump gas and Bel Ray. I tryed Turbo
Blue(leaded 110 race fuel)and Bel Ray this year. I must say, I am
surprised. The bike runs much better with race gas!! I am a believer..
Is it worth the money? To me it is, now that I tryed it!

Here is my experience: I have always run 50/50 with Superbee 105
octane. I went to 100% superbee when my motor was ported by noleen.
Everything nice and dandy until last week. I switched (due to my
distributor switching) to 110 octane VP race fuel. My bike would cut
out BIG TIME when I was WFO in 5th (95 wr-250 by the way). I took out
the plug and it was way too lean! Hmm, just changing fuel leaned it
out that much? (it was higher octane). So I tried larger main (from
360 to 370). My bike still sputtered big time. Have not pulled the
plug again, but I will. I did try Phillip-66 108 octane and it did
the same thing. Any ideas?

There are many different types of race fuels... Some are still oil based,
some are oil based with butane and some are alchohol based fuels.
I don't know about VP, but Sunoco (CAM2) is oil based and Fass Gass
and Torco are alcohol based. (This is what I am told)... Alcohol based
will require a richer jet, but will run cleaner and cooler.
They are all different chemical contents, all different mixtures.
There are those out here that will say "I have done it for xxx years and
never had a problem"... My response is OK, don't change a thing. I am
not out here to sell fuel or say I have the key... I am simply stating my
experiences.
I have also spoken with 1-800-RACE-GAS and their technicians are
very helpful. They help you understand why not to use race gas mixed
with pump gas and why not to use A/V gas. Yes, they are Sunoco
technicians, but if you listen to what they are saying it makes sense.
(Oh, if you call them, leave a message that you need a race fuel dealer
near you, then when they call back you can ask some technical advise)
I am not trying to convert anyone... I don't care who runs what.
Hey, wanna talk performance.... <grin> You ought to see our LEM 50
run with 116 octane race fuel and a little nitro booster... I am afraid to
run it too long, I don't know what will happen. But, can you say R E V
TO THE M OOOOOO N? WWWeeeeeeeee! :-) Sounded like a CBR! Had to jet from a 170 to a 210 before the plug was tan! Scared me!
I don't like to experiment to that extent.

If you have your carburetor jetted right, which I have done to
my YZ, race gas makes absolutely NO difference. I tried them both...

My experience with some types of race gas is that it looks much
different on the plug than pump gas. Unfortunatly, the race gass that I
have used looks very lean when it isn't. To the horor of most that may
read this I go by feel not plug reading. Your bike sounds rich and when
you went to a larger jet the problem got worse. What does that tell you?

I can probably help you out with your jetting. And, I'd like
to talk to you tomorrow morning about beginning to purchase
Race Fuel from you. I plan to run race fuel in my *new*
bike (no, not the 125 I just purchased, I'm talking about the
new 250 I just ordered this morning). I'll fill you in on the
details tomorrow as I need to have you do a brake job on my
Ranger.
See ya tomorrow! ;)

Funny, I called a tech at VP and he told me that it would be better
to run VP C-12 straight, but if cost was an issue, it would be better
to run with a mix of av-gas and C-12 over pump gas and C-12.
I am currently running straight av-gas and it works just fine.
I may switch to half VP C-12 and half av-gas mix for the race
season for two reasons.
1. Cost. 100LL is around $2.00 a gallon
2. The lighter race fuels also have higher lead content, Les
at LTR who services my motor doesn't like cleaning the
stuff off the exhaust ports. On a two stroke where
you tear the motor down more often this probably
wouldn't be an issue.

The specific gravity of VP C-12 may be different from what you
were running before. Call both companies and ask for the
specific gravity. Also, ask for the specific gravity of pump
gas as a reference. This will give you an idea which way
(lean or rich) and by how much you will have to rejet.
