    Are electronics legal in alcohol? Doesn't the transbrake button when released send an electronic
    signal to the tranmission or not?

    if you can let go of a button in an acholhol car with a auto matic to leave the line isnt that going to make you,re reaction times way better than someone using a foot clutch? what kind of mods could you do with a cluch car to make it equal like releasing a button that lets the clutch pedal go with an air switch and silanoid on the pedal or something like that?

    That'd be an awful BIG Solenoid to hold one of these clutches at 5 or 6 grand on the starting line...

    Actually you do not need a solenoid to hold the clutch in..I know that the clutch discs at 5 or 6 grand is a lot of strain but there are kits avaialble..I have seen air release units (I would think for lighter clutch programs) but what I know works is an electric trailer brake assembly.. I know it sounds far fetched but I have seen it work on a couple of cars.. it is pretty simple ..Battery, button and trailer brake magnet set up ..One of the cars that ran this set up was a blown/clutch deal in a FC for Top Comp..They used a delay box with it..but only because it was allowed...The whole assembly is done at the clutch pedal not by the can

    I beleve that I read in the Nat. Dragster that the release of the trans brake has to be done with a foot switch

    We run in the the outlaw promod. You need to use the trans brake to change from forward to reverse and to put it gear

    In the IHRA rule book It says hat the transbrake must be operated with the drivers left foot. I don't know about NHRA. We run a lencodrive with a foot operated switch in a funnycar and it works great. I also run a lock out switch so that when you punch second gear it disables the transbrake.

    I think what Stacy was saying is that in NHRA the use of electronics in TAD would prob. be elegal.

    obviously nhra considered this when they let the lencodrives in. you cant run a delay box.

    before everyone jumps on the bandwagon of saying how much easier the transbrake launch is, think about a few things...

    one, there's nothing stopping a clutch car from coming up with a 2 stage throttle pedal to go instantly to a preset stage rpm.

    two, the lencodrive with the converter only leaves at 3500-4000 rpm max. from my experience, the higher the launch rpm, the quicker the rt.

    three, i doubt any such solenoid set up would be competitive in the alcohol ranks. it would be hard to get the timing right to release the clutch. if you let off a button quicker than you floor it, you'd be lugging it every time. any rt gain would more than be offset by performance lost.

    I think Will is right about the transition from releasing the button to going to WOT..but if NRHA/IHRA were kind enough to allow you to run an air cylinder on the throttle cable then the clutch to WOT issue would be elimanated ..and the with an air cylinder you could preset your staging RPM and it would stay a bunch more consistant round to round
