Please keep in mind that fast drag-race cars will still require a proper catch-box no matter how long the shut down area (unless it's unlimited). You're only trying to slow it down to avoid a full speed blast into the catch-box.

Good luck!!!

Correct, Plan A didnt work, the dead short....... I have 18 feet, the dead short was placed at 14 feet, the momentum of the car as you stated did nothing, actually, hit the pillow jumped off the track and broke off the front.....

Plan B , now is to move up the dead short to 13 feet.

Plan C will be to add in different resistors to see if that create a better outcome.....Geez, might have to resort to HO scale  for this space to work.
