How do you know it's a diode converter?

It could have like a borg warner sprag i suppose, I don't know if Hughes will even build one but I know if you tell em you're 1/4 mile racing it'll be an active stator converter sprag or diode.


When we figured out the slip 1/4 mile, I knew it had an active stator. Like I said it most likely has a stator that multiply's torque on the high end of the scale below stall for Pro Tree racing, but isn't as efficient down track.


I have one like that I bought from a buddy, he had in his attic ten years, when I called PTC to see what its story was, they forecasted its performance by the part # I gave them.

Put a M/T radial on it. They're making bigger sizes now, I know there are a few NHRA Super Stock guys fast on them.

Shocks, tires, gear. I go 1.27 in the Nova w/sb 3250 pds. You just gotta work smart. I run a 1.69 low with either a 4.88 or 500 gear.

I has also been 1.30 60 ft with a 1.80 low 4.10 gear but the conditions were -0

Call this guy OP. See if he still has this transmission. This would get you going 1/4 mile.

sounds like my rear gear, tire size is optimized. So do I need a lower 1st gear?

Nah, you could run 1/4 mile with a 5.00 gear with the 33's. The shorter 31 will pick it up a little, try it.

Proflite would be the way if you did go 3spd. I could def go faster with a Proflite 1/4 mile.
