I'm a very short time from powering up a Drag Track at Upstate. It was part of a long term plan but recent events have forced me to change plans and move earlier. I've asked the previous track owner, the power supply manufacturer and a racer that travels around and sees all sorts of tracks just what is the standard and recommended power supply configuration for a 1/8 mile competition track. And all three have given me completely different answers. I am concluding that you can do this in more than one way. Since I am buying from scratch, I would love to hear from those with no regrets as to what exactly gives you the best results.
