"It was cheaper than Trick was in Seattle at the pumps"

Trick and pumps has all sorts of connetations not related to rallying.

Seriously what is "Trick" ?

The highest octane we can get up here is Chevron 94, at the pumps.

Now if we (in North America) were to increase octane, produce smaller engines, bump compression, use less fuel... Nah that would be too European (let's keep lower compression, lower octane, big displacement, and somehow lose the dependance on foreign oil)

Trick at the pump is racing fuel sold at a couple service stations in this state. THE trick at the pumps, well now that may be something entirely different.


So I'm guessing you can't go to the airport with a couple 15 gallon drums in the back of a truck anymore?

Gene I've never tried to buy AVGAS or FS11, so I' don't know.

Gene,

The TSA is making getting on the ramp very hard now. The next time I am in Pt. Townsend I will ask the FBO guys if they would let me fill up a gas can. There may also be taxation issues to be dealt with.

I really like avgas. We used to put it in the lawn mower enging that powered the airplane tug. That little thing would run so good!

When I rallied in Africa, avgas was all we had. I remember that we used an addative called Redex. I dont' remeber having o2 sensor problems from the lead.

Robert.

We used to drive to Tumwater Airport and pump av-gas right to our rally AND service cars! It was so cheap in '80s.

Toluene: That shit really works! I read what The Greatest Cheater - Smokey Yunick - wrote and copied the coctail and put it into Al Rocca's road race Starlet at Riverside.
After Al won they checked the gas and wanted to disqualify him for "112" or something like that octane rating. Luckily, I had bought legal race gas at GULF station day before, and had the receipt, so they let him keep the win smiling smiley

Gene, I suspect you know about the very high lead content of 100 octane 'low'lead' Avgas; my understanding is the 'low lead' has higher lead content than leaded auto gas had. How does the effect current rally car engines?

Don't be suspectin' me of anything...I didn't know that until right now. A little research shows 100LL has slightly less lead than a wheel weight and that's about it. Amazing, you can't believe anything anymore, I hope the ShamWow isn't a scam also...
'
I haven't bought "fuel" in about 20 years and until now haven't even really discussed it. Back then it was always carbed rally cars so lead or no didn't matter engine wise. I can't recall the subject even coming up in our rally forums before.

DON"T run 100LL in a rally car, it ain't the answer...!!!

Aha! A good discussion , once again I learned something. Thanks Mark !

I ran 100LL in a fuel injected engine with a functioning o2 sensor for several thousand rally kilometers. I had no problems although I did not have a catalytic converter.

Interesting, Robert. I assumed that the high lead content of 100LL avgas wold effect the O2 sensor. It certainly should not be good for a catalytic.

And I can only wonder about Avgas lead content before it was converted to the 'low lead' variety!

Well, Gene, I guess it would be OK in the 'new' '72 Opel with the carbs......no O2 sensor....no cat....if I ever get time to work on it again......

BTW, once we used the Sunoco 104GT in our Starion. Made no difference over 93 octane whatsoever; a waste of $$. Even with a bit higher boost and higher CR now, the 93 pump Sunoco is fine and the car moves out very nicely, wiht more torque than traction in the lowest 2 gears.

I later realized that it was not of any real use without the ECU being changed for more aggressive timing advance. So anyone considering higher octane, be sure you have the engine timing (or CR) changed such that you can actually make some use of it. Otherwise you are wasting your time and $$.

In my search for enlightenment (after Bowers so ruined my 100LL fantasy) there was mention in a couple forums that Denso o2 sensors were pretty resistant to 100LL fouling.

We were running an OEM VW/Bosch sensor. It lasted an entire season.
