electric throttle stop
 
i have a 4 hole dedenbear electric stop i've used for quite a while.my car isn't super powerful only running 136 mph in sst.my problem is occasionally the car spins coming off the stop and i also wonder if the stop slamming open causes fuel mixture issues.i wonder if an adjustable rate pneumatic stop would help cure these issues by slowing the opening and closing rate.it seems like it wouldnt be hard to make adjustable dampening device like a dashop for the electric stop

Go to the air stop, you won't regret it.

Are you coming off the stop in low gear?

Other than switching to air (I don't care for either, but they do work) You might try raising the stop RPM so you aren't coing off with such a big throttle hit....although that will lengthen the time on the stop and may hurt mph a little. Some suspension tweaking might help as well to try to keep the rear tires loaded and stuck to the track.....

I've been daydreaming about doing this for a while. When I was doing engine development for a forklift manufacturer we used dashpots as an "idle up actuator" to mechanically kick up the idle in response to a loss of vacuum. Somewhere I still have some of those prototype dashpots, I've thought about using them with a needle valve regulating the flow out of it.
