2013 STU Discussion!
To submit a letter on-line, go to www.sebscca.com
Murph, send ur letter asap, like this weekend!
One thing that we need to point out to the STAC is that the new cars that have been classed in STU were classed based on the CURRENT performance of the STU cars. Now they are going to try and lower our current performance level - that's not fair at all! The C5 and Z could now be very much over dogs!

I agree.
But these take backs that keep happening in ST* really boil my blood
I sent a letter as well.
The Subaru guys around here would be most affected by this change, so I'll see if I can get them to write some letters as well. We have 100 Octane on-site at one of our biggest locations. They love to mix in substantial amounts of 100 Octane for additional safety margin, especially on the hot days.

My car is tuned with 93, but I like to mix some 100 if available during the really hot days especially with 2 drivers.
So the SCCA reasoning behind this rule is because they do not want you to “tune” the car with 100 octane? Or you cannot have anything higher than 95 inside the gas tank?
Are we trying to get 100 octane as legal gas because the cars are tuned with 93 or because the STU cars are tuned with 100?
-- If you are tuned with 100 only, you may not drive the car at all on the streets.
--If you have 2 maps, how do you make sure that the mixture is good unless you use about 2 tanks of 100 before switching the maps?
If this is the case I see the logic behind it… because either way you need 2 tunes, spend a lot of money in gas or never drive the car on the street or pay for 100 octane gas to drive around.
Now to actually test the gas at events, I don’t know…

Rule as Proposed:
3.6.A. Stock and Street Touring® category vehicles will use fuel is which is Federally approved for use on public highways. Fuels comprised of more than 15% Ethanol may only be used when specified by the manufacturer (e.g. in the owner’s manual for Flex-Fuel vehicles). Pump gasoline above 95 octane is prohibited.
So I did some thinking/reading... has there been any discussion on how they intend to enforce the octane rule? measure fuel from out of our gas tanks? With what, under what conditions? Will this measurement be comparable to the manufacturer’s published octane rating?
If I go to the station and buy some Sunoco 260GT, I should be legal, but if I buy some Street Blaze, I wouldn’t be… assuming that what they measure and what the manufacturer lists (Machine Octane Number) are one-in-the same… yeah right. Additionally, for example, Trick 101 has been listed as anywhere from 92 to 96 octane (MON) and I’m guessing that has to do with where you buy it… and furthermore, fuel is regulated at the state level, there is no such thing as “Federally” approved for use on public highways. The fuel you buy during the summer in Cali is a whole lot different than the fuel you can buy in say… Alaska…
my-two-cents, I will vote in favor of the rule, if they replace the word “Federally” and up it 1 octane to 96 (as defined by the EPA’s requirements for specifying MON, - ASTM D2700 ).

The EPA regulates fuels and is a federal agency. I see nothing wrong with the "federally approved" wording.

Ah, thanks for clarifying, sorry I didn’t know that
For those following along at home there are three ways of measuring octane, RON, MON and the average of the two. This average, R+M/2, is what the US (and Canada) show at the pumps. Also referred to as Anti-Knock index (AKI) or Pump Octane Number (PON) – Wikipedia.
Race fuel manufacturers list all these numbers in the spec sheets and yeah, 95 ain’t gonna cut it.
