AV - Gas?

[olboatman]

im told av gas now adays is not what you concider race gas????

This is what I understand also. I buy 91 alky free at a local airfield and mix with Sunoco 110 LL bought at gas station. My chainsaw and weed wacker both love it 50% ea. and Klotz R50!!!! lol

Re-formulation for Winter.

From what I understand....they have to add a lot more 'stuff' to ethanol blended. For me less is more.
I use 91e free in everything....from the 200xs to 53 Flathead.

The pure gas site works pretty well while traveling, don't usually have to run a full tank of E10 before locating a 'pure' station. Up North there are more stations 'cuz of the snowmobilers.

Do a search about this. There was a discussion a few years ago. Correct me if my dim memory is off, but I think Jay Smith, who at that time in real life worked for one of the gasoline companies, said that many additives we wanted for our type of use were missing from AvGas.

You have to be either really careful or really crazy to run leaded fuel.

This study provides the first evidence that progressive and ongoing decline in cognitive function, particularly functions such as learning and memory, is associated with adult lead exposure long after exposure ceases.

Lead-brain link

People who have worked in jobs with high levels of lead exposure are up to 3.4 times more likely to develop Alzheimer's disease, an incurable and fatal degeneration of the brain that causes dementia, the researchers told a meeting of the American Academy of Neurology in San Diego. Lead causes brain damage, and strict controls have been placed on lead in paint and in gasoline because of it. But most concerns have centered on its effects in children.

Lead-Alzheimer's Link

The relationship between performance on cognitive tasks and circulating levels of lead in blood and accumulated levels of lead in bone was examined in 141 middle-aged and elderly men Men with higher levels of blood and bone (tibia) lead copied spatial figures less accurately; men with higher levels of bone (tibia) lead had slower responses for pattern memory. These findings suggest that low levels of lead contribute to impairments in cognitive function among elderly men.

Lead-dementia Link

They discovered that men with the highest levels of lead had a nearly threefold risk of developing cataracts. "Lead may contribute to 42% of cataract cases," Hu says. "That's huge."

Bad ****... sad to see so many people handling leaded gas without any protection. Although, the dumber they get... the easier they should be to beat!

Gary its been said you mix 110 race fuel with 91 pump gas 50/50 and you get 91 pump gas? When I was racing the mod v-4 same as your motor the mixed fuel I was getting my ass handed to me could not figure it out? The next race weekend I was running behind and could not get to the station to get race fuel to mix it 50/50 so I just got 91 non oxy and ran that the weekend and kicked everyones ass ? People thought I was cheating some how but the motor loved just the 91 pump gas straight up and started winning a lot of races just by switching fuel ? but some motors with very high comp need race fuel or they will not live long.

A lot of people run race fuel av gas mix when it is not needed, all they do is kill performance. If you do not have the compression needed for the higher octane no need to run it.

And to add to this anyone using Q16 fuel that is cancer in a can be very very careful around it

[racervboat]

10-4 on that brothers,apba would not let us run oxy fuel it was faster though?

[RobF]

I think it was dirk that told me Republic Airport is not allowing gas can fills any longer

[Capt.Insane-o]

Q-16 is evil.

Dave

Precisely.

[71V153]

Unless you've radically raised compression that 'extra' octane don't do squat.

Give a couple more degrees ign timing

Ken I use the mixture I explained in my 25 Yammy and a old modded 35 OMC. Not for octane reasons ( don't run hi-compression) but for BTUs and I see a couple hundred RPM on the top end over 93 w/alky. Got this from a old OPC racer years ago.....and the yard tools love it!!!lol BTW Try it in your sled....you will "feel" what I'm sayin!

[olboatman]

Not to hi-jack......but has anyone tried the "Race Gas" additive?
Thanks
