See this on Facebook and there is a bunch of back and forth on this product.. Anyone used or tried this? https://dwracingairsolutions.com/ "Just Shut Up and Race" Brian Martin Martin Racing 5.66 @121.55 | ||

Back in the 90's, there were several Super Stock, and Comp racers that had air brakes. They figured out if you used enough line length, it would function like a delay box. Those were made illegal, in those clases. I dont know why it would be illegal in Box/SP racing ? You have to put in the effort, to get anything out of it. | |||

I'm no transmission expert, but I believe the heat from being on the transbrake doesn't come from the 12V solenoid... | |||
|
| DRR Sportsman |
The problem I have heard is that the solenoid can act like a capacitor the longer you are on the button the more stored energy in the solenoid making it more timely to release. It’s minimal of course but we are also talking about a sport where thousands of a second matter. I don’t know the previous to be for certain, just that I’ve heard it | |||

Yes, and I agree, but their advertisement says "You can stay on the transbrake as long as you like" uhh yeah I don't think that's true. | |||

FTI YouTube video shows trans temp on the convertor. Start watching at 6:10 and you'll see you cannot be on the transbrake as long as you want. https://www.youtube.com/watch?v=GpHcDWFegNU | |||

Why try to fix what isn't broken? Plus I dont think most dragsters would have room for it. I know mine wouldn't. I have the large enclosed solenoid and it barely fits in my car | |||

I do not THINK it would be illegal in bracket racing but I am not sure if it is any better or even as good and you have to consider it adds some weight.

A diode fixes that. Raceless in California! | |||

in the IHRA rule book under "General regulations, all classes" in the section marked Trans Brake / two step/switches: Trans brake or switch release must be of traditional mechanical / electrical means. The use of pneumatic or hydraulic switches is prohibited in all classes. Not sure why there is a discussion. Joe Without data, you’re just another guy with an opinion. | |||

That's why I like my linkage style throttle stop and a delay box. I push the bump button and the pedal falls to the floor and the engine is at an idle. As soon as I stage, I push the transbrake button and just wait at an idle. I can sit there as long as I want if my opponent can't figure out how to stage quick enough. Top bulb finally lights up, transbrake button is released and throttle snaps to WOT. Delay box starts counting down to release the transbrake. No burn down of the transmission or converter. | |||

This is something to consider. I have learned I am the most consistent by depressing the button only after all four stage lights are on. This means I am at the most heightened alertness for a short time. And with a starting line throttle controller the solenoid one time [heating time] and the converter heat are both minimized.

That settles it then. I do not think air operated would work as well, would add weight and complicate things and now we know it is not legal. While I like thinking outside the box I do not think this one is a good idea. https://postimg.cc/gallery/np3zpruo/ "Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability.

Yep I read that rule also, but they guy kept saying its legal. I assume he works or owns the company. "Just Shut Up and Race" Brian Martin Martin Racing 5.66 @121.55 | |||

It's legal, it is stating that the release must be mechanical, i.e. a standard type switch rather than something pneumatic or switches that use infrared. Years ago Rossi transmissions came out with an air operated trans brake that simply used air instead of fluid to hold the transmission in reverse. I still have my old Lamb Transmission Brake. AFAIK, it's still legal and it's air operated. Clowns to the left of me, Jokers to the right. Here I am....... | |||

I thought Abruzzi had an air operated brake for many years? Sponge Bob had one I think? Never heard anything about it being questionable? The "switch" rule posted is for the switch, not the actual t-brake actuator. As I understand it anyway.....  "Despite the high cost of living, it remains popular." Dave Cook N375 | |||

So you are saying that having a pneumatic solenoid release the transbrake is legal? Without data, you’re just another guy with an opinion. | |||
|
| DRR Top Comp |
Legal or not I think the whole system is heavier and just do not think it would be as consistent.

Curly back in, I believe, 2004 there were a few air cylinders that completely replaced the transbrake solenoid, well it took about 10 seconds for racers to figure out that if you lengthen the air line and/or a carb jet in the line, you could adjust the timing of the brake release. Which is when they changed the wording of the rule to "Trans brake or switch release must be of traditional mechanical / electrical means. The use of pneumatic or hydraulic switches is prohibited in all classes. " Joe Without data, you’re just another guy with an opinion. | |||

As the VOLUME of air changes the release time but air PRESSURE should also change release time. Such as when regulator spring gets weak or sticky or air pressure changes in the system. Possibly large Barometric pressure changes may change release time with an air operated system? I can see where those who can not use a Delay box could benefit but I think it brings too many other variables and weight to be viable for most of us legal or not. https://postimg.cc/gallery/np3zpruo/ "Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability.
