Update on MDS turbo weights.

[WyoBoy1000]

For those that would like to know. I am running a twisted rg 09 HCR with a KMOD suspension, 162 PC and MDS weights. Ride in Cooke City mainly around 9000-10000ft. I am 220lbs and with tools, gear and gas prob around 270lbs.

I put the MDS weights in on the hill and compared to the twisted setup. I gained 9mph track speed on 6lbs of boost. Since I have played with a few thing and am running a polaris Black/Green spring (like the black but a little stiffer on the bottom same on the top) I have one long screw and washer in the tip. The secondary is a stock setup 36* helix, orange spring with one plastic washer and shift assist under the spring. I have it set so I can creep around if I want but it will still upshift very quick. When pulling a sidehill or long climb the backshift is instant and rpms hold within 50rpm on wot pulls crossing tracks or what ever. The clutch temps are cooler than I have dealt with on any sled (sometimes they will get a hotter if your creeping around and engage and disengage clutching a lot) all and all I am very happy with it.
After playing with these weight I can see from one turbo kit to the next you may need adjusting to a personal preference and riding style. On 10lbs it really kicks a$$. But 7lbs is a good overall setting for thick trees, sidehilling and climbing.

Steve at MDS has the weights in stock so give him a call.

Do you perfer the 36 Helix? Or did you change that for use with the MDS weights?

It works the best with the MDS weights, I tried it with the 36/44 and at first(before I got the right spring and weight setup) it was a little quicker shift but higher belt temps and lost about 5mph track speed. tried a 42* and the shift was slow, 38* was pretty close but was down 2-3mph. So I found the right spring and right amount of weight and it works the best, I might get an adjustable spring style helix so I can tighten or loosen the spring for different conditions but its really not needed just something I would like to play with.


The MDS weights provide the shift with a stock secondary unlike what we are used to with other weights. Having good clutching to start with and gaining 9mph track speed is crazy, and its not just trackspeed, I went from sidehilling over the top to pointing it straight up and over the top.

This is my high elevation setup and at lower elevation and higher boost different helix's may help. But this works great from 6-10lbs at 10000ft.
