Anyone know anyone out there who is conversant with Fuel Testing? Not so much a commercial tester but someone with knowledge that might be willing to consult with me on the NASA nationals?

Thank you

Jason

Jason,

I'm no guru, but the path you take depends on whether your are specing a fuel or not. Example:

1) If you say that the fuel may not contain (just making one up here) cyclohexanone, then you have to have a validated means, usually Gas Chromatography/Mass Spectroscopy, for detecting cyclohexanone. This gets complicated in a complex mixture like gasoline because you have to account for every little wiggle on the graph that comes out of the GC/MS. If you say that it can contain no more than 5% cyclohexanone, things just got really complex. This will be slow and difficult which equals $$. There are dye/reagent tests that can do some of this, but we all know that the good fuel blenders are able to outsmart the reagents.

2) If you say that only fuel from sources X, Y and Z will be permitted, then you can use a much simpler form of GC/MS, or even specific gravity/specific density, to match the fuels. You don't care what each little wiggled in the output from the graph means, just that they match pretty closely. A different fuel from the spec will stand out like a supermodel in a lineup of pygmies. This could take little more than 30 seconds per test.

Do I turn my 99 Hard S into a killerfast SM or seek a donor?

Kent,

It will be option 2


I'd like to tracer and then easy tests for additives. Sounds like you may have more info...

pm me please

thanks!

Jason,

I'm really not an expert, just know enough about analytical chemistry to be really dangerous.

Have you called these guys:
http://www.ridgenet.net/~hideseng/prod02.htm

Other than a true GC/MS, I can't imagine a better kit than these guys have.

The only catch is that all of the fuel makers know the tests as well, so they have figured out how to game the system, which puts us back to Gas Chromatography.

Jason,
If you decide to spec a fuel like last year (which I am all in favor for), See if you can cut a deal on the price. I hate it when you have to use a certain fuel to suddenly find that fuel is a $1 more a gallon.
Thanks for your hard work and efforts to try and get this "spec" field back to "Spec".

31st in the nation. If I could keep the car on the track and put on the oil cap I could be in the top 20.

Sean, I do plan on a spec fuel. And yes, I'm trying to get a deal. We'll see.

Thanks

Jason

Jason,

I don't see anything yet in the Championship Supp's on fuel. I also hear that the track sells Texaco 91 octane and Sunoco 98 octane. I would assume you'll be spec'ing one of those as the spec fuel, correct? Tracer too?

Thanks,
Andy

Jason
call Dave Gomberg form the CRB, he did all the research on fuel testing for SCCa and knows this stuff inside and out, I am sure he can give you the information you need.. On second thought.. I will text you his number [Smile]
