Just after some info on AVGAS.

Hypothetically......what would happen if i injected AVGAS into an EA?
The engine is mildly worked with an ACL race kit in the guts. The engine is due for a head gasket very soon and i'm game to see what would happen but thought i might get some advice first.

i thought avgas was illegal to use on the street. Where are you getting your supply from because i thought they made it illegal to sell to car users?

It is illegal to use on the street, and it is illegal to fill a car from the pump, but there is nothing to stop you from buying a drum of it, or getting a drum filled with it, and putting it in your car later on.

The thing i would be making sure of first is that it is 100% unleaded avgas that you are putting in, there is different types, im pretty sure that most of them are mostly unleaded now, but if there is lead in it, then it will destroy your catalytic converter very quickly.

Yes it is illegal to run on the street. And yes it is unleaded AVGAS.

I get it from the only servo left in perth that sells it (as far as i know).

What type of gains would you expect? Would it be like a shot of NOS or just a cheapo version of it? 10-20HP maybe?

not ford

Also your oxygen sensor will die almost instantly due to the obscene amounts of lead in the fuel.

Avgas is a higher quality, higher octane fuel, but is not like nitrous. It's like stepping up from standard unleaded to optimax, except it's a step up from optimax. It's of most benefit if the car is tuned to run on it all the time, which is probably not going to happen......

"AVGAS" is not illegal on the street if used for tuning purposes.

If you tipped a heap of AVGAS into your tank and left it under the same tune it would probably go really shit and cause you problems.

AVGAS doesn't automatically make your engine go better. But if your engine can benefit from the better tune you can give it running on AVGAS, then it CAN be better.

Don't listen to your mates that say "Ohh, I put AVGAS in my car and now it goes like, full sick moite"

I run it in my ea and have had no probs. Every time I go flying, some for the plane some for the car :D. It is a cleaner and higher temp burn. Good if you are running duel fuel as the burn temps are similar (Less tuning problems).
A lot of people running straight gas, will run in there engines on AV Gas due to the better lub of AV Gas before going to straight gas.

Run it you'll be right.

Judging from these posts ......i think i'll fill her up. I'll see if i can get some for the next drag meet just to see the difference in times.

turboute

Im in perth too, where do you get it from? I have to run some petrol through my engine every now and then. and if its true that it would be better for my engine I might try to get my hands on some.
