I said in the posts that my gear ratio was 2.58:1 , that is correct for 8tooth drivers, because I use 7 tooth drivers the real number is 2.87:1. I also said that the top speed was 75MPH at 1:1 , this is not correct . Top speed is 65MPH at 1:1 , with a theoretical top speed of 78MPH at 0.80 overdriven. Sorry, I strive to be accurate.

In the Turbo clutching post the gearing numbers being thrown around were 20/39 with 9 tooth drivers. This is a 1.95:1 ratio.

Turbo on low boost at 10,300RPM- 120 foot pounds of torque
My stocker at 10,300RPM- 83 foot pounds of torque

Clutch ratio in low gear- 3.8:1

Torque at drive shaft Engine torquexclutch ratiox Gear ratio

Turbo- 120 x 3.8 x 1.95= 889.2 foot pounds of torque

My stocker 83 x 3.8 x 2.87=905.2 foot pounds of torque

Hey this is wierding me out, the stocker is making more power of the line, oh well, maybe it just needs a little more boost!!
 

The Mc Xpress at 8#'s makes 139#'s of torque, which would be low boost.
 
Buckeye you have thrown my calculations out the window. Why did they have to make that kit so powerful? Just kidding. Actually I think that the new rearmounted Turbo from MC-EXPRESS is the best kit to date. Because the gearing in my machine is very low, the primary clutch upshifts much quicker than the Turbo example I made earlier. AS speed increases the Turbo will lay much more power to the track and leave my stocker in the dust. Down the road I will buy a turbo kit , and I will try to take full advantage of all the power that will be available. I will start with 8 tooth drivers , 43tooth lowwer gear and a 20 or 21 tooth gear on top. Turbo guys, has anyone put a black ink marker line on the primary clutch and then done a full power uphill climb to see were the belt is moving to on the primary sheave?
