Legal fuel?

[sam]

Same meter locally and at Nationals, it is a standard and is checked against a standard reference chemical that is the same everywhere. Gas that is not stored properly can change, so there is a possibility of having fuel that tests OK at one race go off the scale at another. It would not be the fault of the gas or the meter, but the handling & storage.

it might be slightly heavier

It doesn't measure weight, it measures conductivity. Gas does have a weight spec, but it isn't usually used because you can make oxygenated fuel weigh more or less than spec.

I have a meter for sale if anyone is interested??? It is the DT 47FT jdmpack@hotmail.com
$275.00 plus 5.00 for shipping.

Which model?

Works For Me

I heard or read where someone was mixing AV or racing fuel 50/50 with pump gas and was passing the digitron. Anyone with experience here?

I mix pump race gas, I think it is Torco, with 87 regular. It comes out to around 100 octane if my calcs are right. Passes each time so far, but beware, it does not like to be out in the sun, or left over for the next race. Like I said, in my area it works, not sure anywhere else, it depends on the ethonol rating and how much other garbage is in the tanks.

Fuel

Was this topic discussed any further at this years national meeting and if so were any changes pending for 2010?

I guess not.

[G Stillwill]

I was there but dont think this was ever brought up at the National Meeting.

[sam]

My prediction is that nothing will be done as long as there is legal fuel at a gas station within 50 miles of the Nationals.

Where is the Nationals in 2010?

AV gas is a problem around here. I called the local commuter airport and sure the will sell you AV gas as long as you have a plane. They told me there is some sort of tax law which prevents them from selling it to the general public.

Part true and part BS. It can be sold to the general public ... as long as it is not for road use. Fuel used on roads must have the federal and state road tax paid, there is a pretty big fine for using untaxed fuel on public roads, but no penalty for the seller. A lot of airports use that excuse to refuse to sell to drive ups and they are private businesses who may do as they please.

So, it would definitely be a no no to drive up and put some in your car, truck or SUV. But carrying some away to use in your boat, jet ski, off road bike or 4 wheeler ... all within the law

You could try telling them you know the law and are not going to use it on the road or if your nearest airport won't sell it, drive to the next one. My local airport sells it to me every time I drive up and tell me they sell quite a bit to the souped up jet ski guys around here too

our Regional Airport is happy to sell it, as long as its going into a container.

? on AV Gas

The airplane engines run at a much lower RPM than our engines. Is the AV Gas designed for a slower burn for these lower RPM motors, and will it give the desired burn for the higher RPM motor that we use?

[Skoontz]

As it was splained to me, not only is it a slower burn, it is a hotter burn. Years ago, AV gas was lead free because the lead would bridge spark plugs and foul them out.

But, consider that was way before the newer more advanced ignitions that can throw a spark 1/2" or more across a gap, when point ignitions had a hard time making 1/4".

It is also probably going to be heavier fuel, heavier fuels, burn hotter and slower.

Nitro, for example is very heavy by weight, burns slow, so slow that as the fuelers run down he track you can see flames belching from the pipes. That's because the nitro is still on fire when the exhaust valves open.

Anyhow, would be interested in hearing other tidbits on this topic, tis good stuff!

[G Stillwill]

Bill this usually starts a war on AVGas let me get the pop corn....lol.. It does have a slow flame front and if all the fuel isnt burnt in the first 28 degrees after top dead center is goes out the ports. Good part it does pass the meter everytime. I have tested it time and time again and dont have anymore good parts to tell at least for a low compression motor

[Skoontz]

There are enough wars going on right now, right here in region 12.... Please keep it civil, educational, entertaining, or drop it....
