Pro Extreme Ratios

gear

10,850 to 11,200 through the lights

 

How often do you cycle out your rods?

 

You have to remember that we run 1/4 only. I wouldnt want to go 10,500+ through the finishline personally. We shift it at 9800-10,000 and go through the lights at about the same. Works for us. And runs well.

As far as 1/8 mile RPM, its right in line with what Sean said.

 

gear

20 runs that includes all aborted runs. even if they look good still change them.......

I believe that Hugh Ridley has 2 of those 1.18 compound gear sets, 2 cases and the pair of shafts for that setup available. I think that one is new and the other has a couple of runs on it. There might be an adapter ring or something else there, it's been a long time since I looked at those pieces.
