TSO Rules?

[EightSecV6]

What are the rules for the class? Are they identical to BG? We surely would like to be lighter and not get any grief about the turbo!:WOW:

It is our understanding that we were all to keep the rules the same between events. I am not personally aware of anthing different, or any TSO issues at this time. Nobody has said a peep to me.

Hey Big Jim....would it be a safe bet to ASSume that while under protest and criticism of our peers, we were allowed to run in BG under THEIR rules so we WOULD be permitted to run TSO in Salem with the car set up exactly as it was in KY? I really dont want to go through what I went through in the staging lanes in BG again.
Thanks,
Bill

Hi Billy, okay... you've lost me... PM me with specific's, I don't have a clue what transpired there.

Billy: I am also at a loss here. Perhaps Chris Lyons could shed some light on this. If this is a sensitive issue, lets keep it civil so we can try to straighten it out. After all, we want everyone to come to Salem and have fun with no surprises.

Scott, do you have any insight on this?

I'll just throw it out there, I dont have to PM it!

Basically, we followed the rules and interpreted them differently than others. There were about 11 entries in the class to be peer teched, we were about number 9 or so in line, EVERYBODY's car prior to ours were teched in about 10 minutes for all of them combined, that is correct, about a minute or so each, blow the horn, turn on the lights etc etc, the peers took approximately 45 MINUTES on just our car when they got to it trying to find infraction after infraction.

The class allows a MID FRAME 88 turbo, nobody could clarify what that actually meant for WEEKS prior to BG, no large frame or thumper style turbos.I bought a MID FRAME (as classified by PTE) GT47-88 turbo and installed it on the car, several of our peers at tech whispered and talked and one in particular was outspoken and I felt he was being used to present the feelings of several others who didnt want us to race but didnt want to say anything either. The OLD 88 turbo has a smaller physical sized compressor and exh housing but it is nowhere near the size of my LARGE frame PT98 on our fast car.

The rule on the exh says it must exit at or behind the rear axle, we took it back to the rear TIRE and turned it to the outside.
After the turbo was considered legal by the GSNats race director, the exhaust was the next issue, and Nick M stated that he was not sending us home for 4" of pipe (that we didnt extend back far enough)

The rules make no mention of a core support but after the other stuff was deemed legal, they started on us about not having a core support (I fabricated a tubular style bracing and mount system)

Prior to the GSNats, I posted a video of a 8.69 pass and someone brought up the fact that the car had an aluminum rear wing and for some unknown reason, the rules were rewritten to no longer allow an aluminum wing! After petitioning the GSCA about this rule change, it was retracted.

Drama drama drama

We are going to bring the car anyway but we sure would like to race it in TSO and if that cant hapeen, we'll try another class

Thanks Guys

The correct call was made on the turbo... generic housing size has NOTHING to do with a given compressor wheel diameter... as far as the exhaust, Nick made the correct call too, I believe for safety reasons, the exhaust must exit AWAY from the car, if it extends PAST the initial collector, and away from the passenger compartment. Exiting UNDER the car at the axle, is theoretically the same as exiting outwards directly in front of the tire, since you cant blow hot air directly INTO the tire by exiting at the axle center anyways. The rear tire is part of the rear axle *configuration*. In both instances at BG, the correct decisions were reached. We will honor those same decisions. If it's good enough for Nick, it's definately good enough for me.

Thanks Jim, you just took a load off me, I am not prepared to argue again!

[BUICK528]

Billy, I don't have the TSO rules in front of me, but if it says NO thumper turbo's, and the end housings ARE thumper outer housings with an 88 wheel, and a mid-size frame bearing housing, we may not have an interpretation problem, that would not be a true 100% thumper turbo. If you have an 88 comp wheel in thumper end housings with a full size frame bearing housing,(or everything outwardly appearance wise is a thumper except the hidden comp wheel) then I would say the turbo is illegal, people would view it externally as a thumper. I believe the bearing housing is the clencher, in the visual argument of authenticity.
We want no arguments at Salem, everybody please enter the gates ready to play on an even keel.

thanx, Jim

Jim,
That is what a gt47-88 is (we have that one on the TSO car).
Our FAST car has what I consider a large frame thumper turbo, it is considerably larger in hsg and bearing size that the GT47-88 we have on the TSO car.
The GT47-88 has a compressor and turb hsg larger than the std 88 that alot of the guys in the class run(but the frame or brg hsg is the same size).
It should not have been an issue in BG especially since Harry stood right there and told everyone that it was "our mid frame 88" but it was......
