Duke Posted July 30, 2006 Report Posted July 30, 2006 Hey guys, I live real close to a small local airport so I can get AV gas pretty easy. My question is if I've been runnin 93 can I just switch to the AV (104-110 I think) without doing anything at all? Will I see a performance increase? Thanks guys, you have to help educate the new guy! Quote
dawarriorman Posted July 30, 2006 Report Posted July 30, 2006 If you don't need high octane gas then there is no point in switching. It won't give you any performance increase. But it will cost you more. Quote
Duke Posted July 30, 2006 Author Report Posted July 30, 2006 Roger, thanks for clearing that up. Quote
speedfreak350 Posted July 31, 2006 Report Posted July 31, 2006 we have it here to but i didnt like it. It was avbout 100 octane but its low lead. I think it might have aided in my bike phucking up one time. Only race gas for me now! Quote
FasterThanU90 Posted July 31, 2006 Report Posted July 31, 2006 yah u can run higher octane gas no prob it just allows u to run more of an advance on ur timing and for motors with higher compression Quote

I think it might have aided in my bike phucking up one time. Only race gas for me now! Doubtful it was the AV gas that caused it, its lead contents are comparable with race gas. And lead isn't going to mess up a 2 stroke at all. Quote
[email protected] Posted July 31, 2006 Report Posted July 31, 2006 you will burn cleaner and run colder ( if im not mistaken ) if you really want to run ahv gas ..... get a timing plate , and shave the head or put some cool heads on ..... Then you can run the ahv gas with noticiable gains. Quote
bansheefreak Posted July 31, 2006 Report Posted July 31, 2006 it will make it run hotter.. av gas is for high elevation this is why its called avgas.. i would run race gas.. its better for your motor .. but i would make sure you need it otherwise you are wasting money running it to say i run race gas 110...

dawarriorman Posted July 31, 2006 Report Posted July 31, 2006 (edited) it will make it run hotter.. av gas is for high elevation this is why its called avgas.. i would run race gas.. its better for your motor .. but i would make sure you need it otherwise you are wasting money running it to say i run race gas 110... Ok, the whole "av gas is for high elevations" is a load of crap. Its a myth, nothing more (think crop dusting, they stay a few hundred feet the whole time). Do the research if you want, I already have. Its gas, plain and simple. It runs great in a 2 stroke engine, with no consequences. It doesn't run any hotter than other gas, it won't make you run leaner, it won't cause you to lose throttle response or anything else that people try and tell you about it. Find anything that PROVES its not as good as other gas with FACTs. You won't, the only thing you will find is people trying to lead you around in circles with bad logic to make you think its not any better. Edited July 31, 2006 by dawarriorman Quote

My sister's family runs av-gas in all of their motorcycles for years wth no problems they work at an airport so its easy for them to get it. You do have to watch and read labels though because some Avgas contains kerosine. Not good for a two-stroke. Quote
bansheefreak Posted July 31, 2006 Report Posted July 31, 2006 (edited) well i did some research .. might check out this nice read here... http://www.exriders.com/vbb/showthread.php?threadid=93870 also i stated before is what i have known . and heard so maybe i'll learn something from this thread.. might have to go get me some avgas....

speedfreak350 Posted July 31, 2006 Report Posted July 31, 2006 well i know for a fact that when I had my Raptor it ran hotter with the AV gas then with 93 pump! Quote
[email protected] Posted July 31, 2006 Report Posted July 31, 2006 i have my Private pilots licence . and well KEROSEINE** ( jet-a ) av gas is used for turbine motors\ certain turbo prop[s , however im not sure they mix it in with the standard av gas you buy from the pumps at the airport. Av gas and altitude will effect the way the aircraft runs . The higher you go , the lower the compression will get . Therefore that is why airplanes run higher octane gas, it provides the engine with more BOOOOOOOOOOOM for your BUCK , to keep you in the air ... The higher you go , the lower the atmospheric pressure is , for every 3000 feet its considerd 1 atmospheric pressure less *** , As the altitude is increased, the air pressure becomes less, and the density, or pounds of air per cubic foot, becomes less. If the engine is to maintain its rated horsepower at increased altitudes, it must take a much larger volume of air from the atmosphere surrounding it, in order to keep the weight flow from decreasing. I dont know exactly how this corrosponds to a banshee because you are not climbing and decending 3000+ feet at a time , however this is just some knowledge i wanted to share with you all ...... Try flying a cessna 172 at 12 thousand feet with some 93 pump gas... Youll be lucky if u can get the engine to even stay on . Quote
Animalman294 Posted July 31, 2006 Report Posted July 31, 2006 Well I'll throw in my .02. I have been runnin' AV100LL for a while now and I have not had any problems. I talked to Jeff and he told me that if I run AV 100LL then I can run higher compression, but don't need to go with race fuel. I mainly run it because race fuel is $5.50 for per gallon and AV gas is $3.75. The AV gas that you get from the pumps at the airport is usually 100 octane, and the LL is for Low Lead, but it still has lead in it........................ :beer: Quote
