I would think holding them down to 20 volts would help a lot in keeping the speed down. I have stopped 60+ mph cars on my track which has only about 7' total of shutdown and have not broken any bodies but I have knocked a couple of bodies off. I do use a combination of 3' dynamic braking 3' steel strips and a catch box. If I was to send a car to one of these races
I would send a body that I was not worried about. The fastest pancake speed I have hit was about 43 mph at 20 volts.

I don't understand the concept of keeping the speed down on a build that's supposed to be faster? A lot of those parts need that voltage to work properly. I won't be running anything anyway so it doesn't really matter to me. Common sense should prevail in the choice of venue, voltage, shut down, etc. If anyone is not comfortable with something then they have the choice not to be involved. Personally I would be comfortable sending a car to any of our core tracks running at 24v +. I trust they will do what is necessary to provide adequate padding, etc to protect the cars. Sometimes none of that matters and the cars fly off the track before even getting to the end. We all know the risk.

I have to agree with Jeff regarding power.
these kinds of build won't even run well at lesser voltage/amperage.
of course, if one hasn't run at 24 volts, then lesser power will seem adequate.
Dave's shut down seems adequate for 24 volts.
so I also have to agree that the venue is a determining factor.

I will put one to the test at 24 volts and see how it does, don't think there will be any problems.
