Aerocharger and Team Ind. clutch notes

[Aerocharger_Brad]

We got a call from Jason at Team Industries with a request to meet with us somewhere and see if he can improve our clutching. I am not sure he finished his sentence before I accepted and asked when and where? We met in Island Park, ID for four days of testing. In attendance was Jason (Research and development for Team) Andrew Dey (Lead Application Engineer, Aerocharger), myself and a guy named Ray that has the coolest cabin to work out of in Island Park.
As you can imagine, in four days we tried a lot of things including many custom ground parts. We were testing with a Turbo PRO-RMK and a Turbo E-TEC. At the end of the day here is what we came up with:

2011 Polaris PRO-RMK 155” 10psi non-intercooled 6500’ 0-10degrees F, 170lbs rider
1.95 Gearing
165-310 Primary Spring
11-70 Weights
Tied Secondary
Helix 60-66F
140-240 Red Black Secondary Spring

2011 SKI-DOO Summit X 154” 5.5psi non-intercooled 0-10degrees F, 170lbs rider
Stock 21/49 Gears
160-320 Primary Spring
441 Ramp Clicker #3
20gr Pin Weight
Tied Secondary
Helix 62-66 .36
140/260 Red/Pink Secondary Spring
This was a great boondocking set up!

2011 SKI-DOO Summit X - all the same except 10psi
Stock 21/49 Gearing
160-260 Primary Spring
441 Ramp Clicker #3
20gr Pin Weight
67 Straight Helix
140/260 Red/Pink Secondary Spring
This set-up was for the more aggressive rider or RMSHA racer
We wanted to try a 62-68F Helix but it was in the PRO-RMK most of the time.


Please keep in mind this is what we found to work well for these sleds. If you have a different turbo kit, track length or rider weight the set-up may need to change. I hope this is helpful and gives you some insight as to how the Tied from Team may be able to help your application.

Thank You!! Jason for your time and it is great now to “know a guy” for clutching.

Brad...Thank you for sharing this information with our readers. It is rare these days to see companies that will get as involved in sharing the information with readers that may/may not be customers.

Jason is a great person to work with... super helpful and interested in making a better product.

Did you do any testing on your sleds with the stock TEAM TSS-04 secondary that comes in the PRO-RMK?

I am curious to find out what your criteria was for evaluation and what kind of terrain.

Long deep/steep pulls, constant variable throttle on technical tree sections at high % of engine load, Drag racing up a hill, etc???

I have found over the years that riding style and terrain prefs can make a stellar calibration less than ideal depending on the rider prefs. ... even at the same rider weight, altitudes and areas.
What was your "goal"?

What belt did you use? Side clearance? Deflection?

What were the clutch/belt temps?

What combos worked...What didn't and why?
This will give people a better baseline to work with to see what "trends" were moving in the right direction and which ones were not.

I have a lot of experience with the 11 series weights... I have not seen a primary that had series 10's correctly installed previously that would allow the use of series 11's without re-shim of the spider. Did you do this or check the side clearance of the belt? (definite longevity concern)

The 11's load the engine quickly and more aggressively as it shifts out... I can see the need for a higher starting force on the (165 lbs) on the primary spring. What was engagement RPM with that combo?

Did you try a lower starting force primary spring and 10 series weights as well?

20/39 gearing?? Did you try other Gearing combos??

How was the sled for trenching off the line and feathering the throttle in technical situations?

Thanks in advance... keep up the good work!!

We did not work with the stock secondary

With the 11 series , not reshimming I had about .020"

Belt temps depended a lot on loading but I would say on average around 140 to 150 degrees.

The engagement was around 4100 with this setup, not harsh coming in but agressive compared to the 10 series.

My goal was to find a set up in the new clutch that responded well enough to ride the timber and backcountry style that a lot of our customer base rides. I also looked for consistent RPM's and respectable belt temps.Most of the time we were in 16 to 18 inches of untracked powder with an awesome base and we topped out our ride about 9,000 ft. Everywhere I went when I grabbed a handful of throttle it was right there and was a workout to hang on!

We did gear up the RMK the last day to 1.95 ratio and it pulled very hard but didn' t get to go up above again due to other projects.

At the end of our ride I don't think you could wipe the grin off my face. I was very impressed with the performance of both of the sleds.

Thanks again Brad and Andrew, I had a blast working on the sleds.

Jason,

Thanks for that!

What other combos did you work with before settling in on this one? Any trends that you could see as far as helix angle or spring forces?

 

[TEAM Industries]

I tried spring combos as light as 140/200 up to 140/260
anything under a 240 lb finsh would slowly lose RPM under load.

the red/black spring has always been a good performer for our higher elevation set ups.

As far as where I started for helixs, I had a box full and tried anything from 62 straights up th straight 67. For the low speed throttle resppnse the Polaris seemed to like a slight inverse cut so it could rev quickly. The inverse always allowed it to hold RPM's on long uphill pulls.
With the boost levels we ran the 64 or 66 ending worked good and trenching did not seem to be an issue with a little finesse taking off.

Belt temps tended to run cooler as well with inverse angle. Inverse cut I will say depends a lot on boost level as well as preference by rider of how agressive they like the power to come on.
