Just wanna see if were all on the same page here? Seems the tech guys are a little confused so I figure we should see if we can straighten it for them!

Just choose by number 1 2 and 3. Don't be shy now!

Holy crap! That #1 is crazy! I run the 3rd button and still can’t cut a light or go straight if you saw my runs in St. Louis. Right Clark?

Do you have to flip the switch to make #1 work?
 
WOW!!!.. #1 looks to me like an air actuated throttle stop solenoid, being from the throttle stop World.. the interesting piece is the inlet, or outlet, valve which are now sold as adjustable.. just purchased one to regulate the "on" speed of my throttle stop.. with 2 adjustable valves, you can adjust both the "on" and "off" of the stop.. a trans brake set up could achieve the same results.. but isn't there something in the rules that says "no pneumatic"??.. INTERESTING!!
 
It should also be noted that the replacement air blocks for the #1 Stop Throttle Stop now comes with adjustment screws inside the inlet and outlet ports.. the opening and closing speeds can be adjusted in the air block, but are not as sensitive as the adjustment valves that screw right into the air solenoid itself.. the air blocks may be more concealable, but air lines are still required..
 
I looked at this button on The Carter's car at Pomona. I watched as NHRA Tech looked at the button and ask questions. I was going to excuse myself from the conversation and was asked by the Carters to stay and witness what was going on.
First, the button was not on the trans-brake at the time. It was on a switch used to activate their burnout rev-limiter. The car has a trans-brake button under the wheel, ( Just in time) I was asked and I expressed my opinion. The Rules are a little ambiguous. I could read and argue both ways, and I do not have a dog in this hunt. We racers the Carters in the First Round and I was comfortable with their button.
The device on a trans-break would be up to NHRA to interpretive the rules.
ok, my 2 cents. It's phumatic and in its current form with the thumb needle valve adjustable is not by any stretch legal. That said if you were to put a drillable carb air bleed NHRA said it would be legal. That was my understanding, I may be mistaken.
The Carters and great people and I call them friends as I do with any Comp racer. I feel that leaning as far over the edge without going over the line is what makes comp the great class it is.
This will in my opinion be a competitor to the Just in Time button. What is everyone's thoughts
 
Greg, The rulebook is only ambiguous if you wanna tell yourself that! Read it and its all straight in my logical world. Oh and If you look they even put OTHER at the end to cover all areas.

Section 13 page 2 at the bottom. Even says accepted buttons listed on NHRA racer.

I was looking at the general rules, That is a little more clear. in my opinion, the "Just in time" should have never been allowed.
