hi guys,

wondering what gears might work , be good for Barnsville
running a gk800 w/,mc91 oil clutch with 9 tooth
also a margay cheetah mc91 oil clutch 9 tooth

thanx dave

Good starting point is a 9-62. Depending on tire circumference and your weight it could vary up or down a couple of teeth and how hard you want to turn your Macs. I ran a 62 or 63 and it would turn my 91A or 92 around 10500 give or take a few RPM.

That is all well and good for you little guys, ... For those above 200lb, try a 6.8:1 to 7:1

So, how about for a Newly rebuilt Clinton A490? 6.5 to 1? Need to baby it a bit.

How bout gearing for a V5 580 West Bend(bone stock) at Barrnesville.. 210 pounds, new rebuild...on a Rupp A Bone....
9 tooth dry clutch...(vintage Mercury)

Maybe this will help. Kerry Wilson did this for us several years ago. It is still valid.

Front straight length = 348 feet

Back straight length = 491 feet

Total track length = 1385 feet or 0.26 miles.


I also measured the track length using the middle of the track all the way around and it measured 1448 feet or 0.27 miles.
