Clutch Kit
Clutch kits are ready to begin shipping any day. 3-4 sled lengths gained in 0-90 mph testing. Super smooth slow speed engagement. Kit includes a new primary spring and weights (weights are fully adjustable and will work from stock to 260 hp with added washers). We will have a setup sheet that gives you washer placement from stock all the way up to exhaust, reflash, 260 hp, etc. All testing has been done in real world, I haven't had it on our track dyno, only field testing so far. Kit is $239.95!

ECU Tuning

We have in house the ability to reflash ECU's. Quick turn around and great reflashes generated by Evolution Powersports.
  • Stage 0 is setup for adding fuel for an aftermarket muffler $299
  • Stage 1 is going to be setup for stock exhaust, tuning still being worked on!
  • Stage 2 is 12.5 lbs of boost on 91 octane $499
  • Stage 3 is 14 lbs of boost on 91 octane $499
  • Stage 4 is 16 lbs of boost on 95 octane $549
  • ****Stage 2, 3, and 4 a aftermarket muffler is required***
Mufflers
  • Evolution Powersports Magnum muffler $599
  • Sandale 2.5" muffler $599
  • Sandale 3" muffler $599
Charge Tubes
We have the Alpha Powersports charge tubes in stock in various colors. The stock charge tubes really swell under boost, especially when reflashed. This is a great product and they help make your sled yours by accenting the sled also! $168.99

You can check out all the Ulmer Racing Sidewinder products here http://www.ulmerracing.com/productlist.htm?browse=-73647&shopBy=-26776&catalogId=-11683

I will try to upload the ECU tuning & muffler information to the website today or tomorrow as well.

Also, if someone would have a stock muffler kicking around, I'd love to do some modifying to it. So any guys who bought or built cans want to send me their stock mufflers?
 
I send you mine if you want to play with in exchange for your finished product of mod?
 
There you are! I was wondering when Allen was gonna' chime in. I thought you may have turned Yellow on us..
 
I have your full power setup on my nytro xtx and love it I now have a BTX LE have you mountain tested the clutch kit I ride 50/50 Wyoming and UP Michigan? And please post track dyno number increases.
 
Would your clutch kit also work on the Sidewinder xtx Le 137 with the 1.75" track with no tune and stock muffler? Sled would be in stock form for this year and then muffler next year.

Yes it will, we started out testing on a completely stock machine.
 
I'm curious as to why your clutch kit does not include a helix? Does the stock 35 work that well?

At this point the stock helix is showing to work very well. At stock horsepower levels, I don't think there will be much to gain, as we turn the boost up (250+) we may need to change helixes.
 
All items now added onto our website.
 
allen,can the evo magnum muffler be run w/out a tune,and does it need a set of adjustable weights to be run and stay off the rev limiter.
 
Clutch kit ordered, I'm trying my best to keep her stock so I'll take 3-4 sleds over a stock clutched SW.... Thanks
