That's a topic as twisted as abortion and when is conception. In a strict sence, a transbrake should be illegal then. It activates the transmission electrically and hydraulically with an iherent delay through lauch RPM and a number of other variables. I think the NHRA realized that crafty people were already adjusting the transbrake to control the delay of the launch. So if you allow transbrakes, then you may as well allow everyone to adjust the activation with a long switch or whatever else. So everyone using a transbrake is cheating.

Then what about shims for the brake itself in the valve body? Those are not illegal?

They might be Nhra approved But Illegal You don't feel that NHRA specifically saying they are legal trumps your interpretation of the rule book?

No The rule is there to keep from creating a delay from the activation of the trans brake There's always a delay in cars reaction to apied Hp and chassie as well This has all to do with electrically altering a desired reaction this to cause a delay in the operation of a trans brake Illegal No bs. No trying to say this is ok It's Not ok never been ok

Honestly, I could care less. I don't even use a transbrake normally. But if you think getting rid of long switches solves anything, it won't. The adjustment will just be made another way. Plus the length of the switch is not electrically altering the the reaction of the transbrake. It's physically altering the reaction, just like adjusting the bump stop or letting air out of the tires. A Delay box is electrically altering the the reaction of the transbrake.

It states electrically , hydraulic pneumatic any way that the trans brake is applied!! We not talking tires or chassis

8:7 SWITCHES & BUTTONS Transbrake and/or line-loc switches must be NHRA-accepted for use in all classes that prohibit delay devices. All switches and/or buttons must be standard, mechanical connection type. Infrared, laser, retinal scan, fingerprint, light source, or any other non-mechanical-type switch and/or button prohibited in all NHRA classes.
Dennis if your going to pull rules out of the rule book you need to pull out the correct one. Rule 8.2 is for cars using delay timers. Read the above which is from the rule book for cars running classes where delay boxes are prohibited. NHRA accepted! This is no different than safety equipment having to be NHRA accepted! Yes there are buttons out there that are illegal, but there are lots of adjustable buttons that are legal my friend. If this is all you got on people cheating at Gateway then you are really making yourself look silly! It doesn't matter if you don't like it, what matters are the rules pal!

For 2008, transbrake buttons “must be NHRA accepted. Devices must be mechanical spring actuated, and not exceed three (3) inches in length from base of (button) switch to top of plunger. Adjustability is permitted, and may be made by a threaded stop or stop rings. Modifying the delay in the switch by the addition of hydraulics, pneumatics, electric, or other means is prohibited. Contact the NHRA Technical Department for a list of accepted transbrake buttons.”
Here was another explanation from NHRA on the adjustable buttons which they approved back in 2008!

In the pro classes you are not allowed a delay device Thus you can not have a adjustable button or switch in that class What you are allowed in super comp gas even som stock classes is totally up to those classes and tracks The rules say you can not have anything other than a standard switch !! 8.7 bears. That as well as 8.2 sections
