The only thing that I have an issue with is on a carburetor combo, the Racer is allowed 2 OEM type base gaskets. If you can find a base gasket with a smaller hole than the carb then go for it! I think the EFI restricter "plates" should go. They should have to adhere to the same 2 OEM gasket deal as the carb combos.
As far as "throttle stops", as long as they are mechanical and unable to be manipulated as the car is going down the track, I'm OK with them.

As I stated earlier, racers are creative and there are many ways to skin a cat. (Sorry Cat Lovers... )

Considering the short travel length of the electric solenoid used for these anti run on throttle closing devices, if you are running quick enough to run index on less than 1/4 throttle opening of the primary side of a Quadrajet, I would have to think that is a very underfactored combination!

So it’s ok for a carb racer to run a smaller gasket than carb but if an EFI guy finds one it’s not ok. Just think they should be treated the same. Mike McMahan 2543 H/SA

THAT isn't what I said!

I’m just trying to understand. Isn’t the effect of what you said the same?

You're allowed 2 OEM type gaskets, IF you can find a gasket with a smaller hole in it then go for it! But it's gotta be a GASKET.
The EFI guys are making steel and aluminum plates and putting them between the throttle body and the manifold.

Why would you need 2 gaskets other than to put one on each side of the restrictor plate?

Some carbureted combos like a larger "plenum" under the carb. Some don't.

Those can easily be policed in the lanes or at fuel check or any damn place.

My post was made in jest, poking fun at all the fear and paranoia around the Grid. You can read more in the “Un-ring the Bell” thread.

Yes, there are illegal accessories available for it, but you can hook up illegal boxes to just about any ignition system if that’s what you want to do.

I understand that there could be a legitimate argument that any aftermarket ignition system does not belong on a Stock Eliminator car, but that’s a different argument.

Is this the selenoid that opened the throttle a little when the AC was turned on,to maintain idle speed?
I knew a racer years ago that had one of these on a stocker,but I think he was using it for a staging device. Flip a switch and it holds the throttle open for you.
