race fuel vs av gas

M1K · 12-20-2007, 03:56 PM

Whats the diff? Can you run av gas in a turbo'd sled?

hintonatv · 12-20-2007, 07:28 PM

Av Gas is ok in a two stroke. It is hard on valves in a four stroke. A blend of racing fuel and pump gas is a popular solution. For more information visit www.vpracingfuels.com. VP fuel is available in Hinton at Hinton ATV Repair.

If im right,AV fuel is the same but for AV to be called AV fuel it has to be at a minmuim octane.where as race fuel goes from 92 octane all the way up to 110 octane i think...

Thanks guys for your response. I'm just contempleting turboing my M. What's race fuel going for per L. Have read that AV gas is only about 30-40 cents higher than prem?
I did a little research after starting this thread & found that av gas is designed to be used in engines that run between 1800-2800 rpm @ 10000 ft +.
Hey TwinTurbo what r u running for go juice, & whats it worth?

A close guess would be in the $3.00/l range for VP fuels.

Teh other thing about AV gas is that it is not nearly refined as race fuel. Race fuel meets certain specs where AV gas can run for one octane to another. Its like when you go to buy it. AV A gas is 100-111 OCT. So its close to being around 105-106 OCT. Some thing like that. Thats just what i have been told.(Buddy is a fuel man at the airport)

I run av gas in my turbo RX-1.Lots of people run it in the Turbo 4 strokes cause it's only $1.39L.As for saying it's not as refined as race fuel.I don't know about that.I don't think that anyone flying a plane would want an inconsistant fuel in there plane while flying at 10 000 feet.I've talked to the people at esso and they said that it is 100 octane not 105 or 110 but 100 octane

I hear alot of guys adding race fuel into thier tanks I have always been curious to see actual dyno runs on pump gas to race fuel, I agree that it is a positive to run race fuel in sleds that the compression ratio has been increased however in a stock sled putting race fuel in would actually be removing horsepower. Octane is a fuels resistance to burn so race fuel combusts at a higher temp. so if an engine is designed to run at 91 octane and you put 110 octane in it will be an incomplete burn. It's just my theory but I am a mechanic so I do have a pretty good understanding of an engine. a turbo or high compression heads do change what octane should be used but I see alot of guys on the mountain mixing race fuel into thier mainly stock sleds. If anyone has checked this on a dyno I would be very interested to see the results!

Where can you buy AV gas, and how much is it per L??

The higher the octane the cooler the motor runs,it's unburnt fuel that creates heat,just like a diesel, the bigger the injector's you put in the hotter you egt will be but if you hook up propane the cooler it will run cause it helps burn more of the fuel..in a stock sled i would only put 1-2 gal's per fuel up,anymore would be a waste.Remember that ,,lets say vp-111 fuel,doent have 111 octane, but instead it's about 104 octane so it's good to run a bit in every sled,except

the wifes..lol

Everyone is missing one point. Lead.
Avgas has a high lead content (equivalent to the old leaded pump gasoline, but higher), and is consistently 100 octane. The lead runs cooler, but is prone to fouling plugs or deposits on valves, if run at too low temps. (I'm a aircraft mechanic, and know first hand)
The old avgas used to be higher lead, but now all avgas is called 100LL (low lead)

Pick up a 45 gal barrel last Thur,from AFD.it was $508.00 tax in.
VP fuel from Specialty Sleds is about $500.00-$550.00 plus GST
