I've raced at RA many times.  From the pit on any start or restart the cars are at full song as they pass the start finish line.  

 

Unless it's a Miata???????????????????????

If it's not stock geometry, ima say yes.

Well, the protester better be supplying pics of what they think is the stock piston. And be able to prove it.

If its a Miata it's prolly being passed by six cars just as it crosses the line.  Unless it's an ecotec maybe.

What if you "screwed up" intentionally and the car holds more at an angle than it does when it's level? 

You can't tell me you've never seen someone jack up one side of their car to get more fuel in it before.


Jerry is a lot smarter than me. See his response you’ll have your answer.

Regarding compression, start by eliminating all race fuel or fuel in excess of 93 octane. That will keep compression down. 

A few of us on the Board have been beating this drum.  The trick is to get an affordable, reliable tester to use at the track.  Walk pit road and randomly sample fuel.  If anyone knows of one please tell us.

The nose knows.

Yes of course, but you can't DQ someone because of your nose.  The nose leads you to the race gas, but you need a real test to verify it.

Not really,  offer to buy their gas for 2.80 a gallon.  Or hand them some jugs of 93 and see if they will use it.  😀  Sound is being enforced with a tinker toy, fuel might as well be done with noses.

yes but we need something that gives us results during impound.  Or during the race.

This one lists three model numbers. Having the rule and walking down pit lane with some sample cups would cause a lot of people to straighten up, will it catch everyone every pit stop, no.

Thats good now we will us a Russian meter?

We could test it by sending examples to a lab and compare.

Careful, the guy who orchestrated the Russian doping scandal that got passed WADA is in the US now...maybe he's into testing other types of sample now...

 

Got to get this past 10 pages!

How is this of any value? That's instruction on how to collect a fuel sample and send it to a testing lab (and it's from 2011). So how is that of any benefit at a race or in impound? The series is going to retroactively disqualify a team for race fuel two weeks later?

I think that process can get expensive.

No.  Take five samples of different fuels.  Test it using the gauge.  Send samples off and see how they come out.  Once you have a trustworthy device, utilize it.  The rule would be not to exceed 93 or 94.
