Your less than 2 hours from me. Looks like it is ripping. Did you get 19-20psi without having to add a boost controller? You should be close with weight, 162 or 174?

Where you at in Idaho?

Remove the tcv valve and put the mbc in place of it. I like the hallman boost controllers the best. For 20psi, I run 50/50 av/pump gas at 6,000ft and higher. Pump fuel at 18psi Just installed a hurricane header and I need to add fuel to my mid range and wot, so that means more power. Feels like...

We have 4 of the mcx 340 kits in our group. I could not get any of them over 13psi of boost with the mapping/tuner studio software. I went back and forth with mcx on this. Erik sent me different tunes to try and all of them stayed at 13psi max. I gave up and installed a manual boost...

I put the Nytro secondary on 47 degree helix epi purple wrapped 2-3. Belt is running cooler and works great. Can’t tell a difference from the roller other than no slippage. Back shift is great. The button secondary solved my problems. Back to back pulling chutes yesterday in wet heavy powder.

I pulled the stock sidewinder clutch off and put on an apex clutch with dtya-2's. I have the secondary wound to 3-3 with the epi purple spring and still a bit of slippage. With the big track and big power it needs a tightly wound secondary. I'm going to try 6-1 next. I do think this roller...

Running the 8dn belt now. I'm actually running the quay70's with the large screw in them, not the dtya2's. I tried the stock secondary spring at 3-3 and clutches were even hotter. I'm back to the epi purple spring wound to 0-1. My next thing to try is the nytro button secondary. The...

I've always had the best luck with stock yamaha clutches. I will be trying out the nytro button secondary soon and will post the outcome.

Finally got a couple of decent days on the sidewinder. 2' of powder. I have the yamaha 35 degree helix with an epi purple spring at 0-1. Primary is fully loaded dtya-2 daltons. It pulls 8600-8700rpms. Backshift is quick and feels really good. I'm still running the 8jp belt and did blow...

What primary spring are you running Randy? I put a blue/white/blue from my apex clutch in to try. The stock sidewinder spring is sooo long...

It does have the lockout shock. I was guessing it would be a joke and not work very well. Sounds like it may work better than I was thinking. Thanks for the info!

I will be running 20psi to start with. It's just the stock skid with iceage rails and a cr coupler block. I have run the cr m10, baker skids, and kmod. Kmod is my favorite, keeps the sled light and playful and the nose down in the chutes.

Hey guys, I have a 340 MCX sidewinder with a 174x3 track. I have many different helix's and springs to try to get this thing dialed in. From what I have read most people are having best luck with the stock helix and a stiffer spring. I have an epi purple spring. For the primary I have the...

I've tried pm'ing him a couple times and can't get anything back.

How are intake temps with those boost levels? I would think that a water to air I/C would be really beneficial over 15 psi on that turbo... Also how are belts holding up? I am looking at getting a stage 3 MCX kit too and happy to see a couple others that have done it.

Nice build! I really want an eps turbo apex, but am also waiting to see if someone makes a 350hp+ kit for the sidewinder...

the gateway...aka china buffet

Riding was great on the 27th. We had a trailer so we parked at the first bridge. Had to ride some gravel, but not too bad. The snow up top was nice and soft. There was still plenty for us to climb the Airport chutes, the 90, and the one to the left of the 90. They are bumpy and rough once...

I'm interested in the whole sled, whats your phone number
