Sly, I make a point of "practicing" my rollovers each time I go out, just so I'm prepared for when it happens for real! LOL I'll check out NAPA for a new hose, just gotta get that clutch dialed in, maybe I'll use some of Bruce's parts! Sherm

Tried the XTX out yesterday and not enough snow or long enough lake here in Martensville to do it any Justice. I did hit the limiter a few times but i think that will change with different conditions. Running stock clutching with MCX's weights empty and 8 tooth extro's. Prolly have to throw a little weight at em but overall impression so far "need more testing cuz i got a snowboner that's beggin for a mcx blowjob!" Pretty sure I saw 8psi on the gauge too and I'm at 6 turns out on the wg. So Sherm if your around 7 that would be concurrent with what I'm seeing. Have to turn it once more. I think Sakatoon is around 1650 feet or there abouts anyways. Well hopefully the 3 Turbo Tards will be headin to Weyakwin this weekend for a little testing and some good ole ice drinking, oh and maybe a little fishin too....
A dayco 70921 is a one piece hose with a 90 in it and then you can cut it to the height you want...works good.
Here's the most recent of our testing after two days of great riding!
My sled, stock primary spring, 8Bu's loaded right up (might have to washer it yet), stock secondary, 162' track, 19 top gear, rpms staying pretty much in the 8700-8800 with the odd 9000 showing up. Rod turned out 7.5 turns and boost is pretty much where it should be as per the charts.
Bruces sled, blu/whi/blu primary with 8BU's loaded right up, stock secondary, stock 153" track, 20 top gear, rpms staying 8600-8800 and boost seems right on. Can't tell where his rod is because the threads have been "ground" down from the factory for some reason so can't turn the rod all the way in?
Couple things to watch for: (1) that hose that vents to the atmosphere drips gooy oozzy white crap that makes a mess of everything! Just moisture with an oily residue but, messy. I attached a bottle to the hose, put a couple holes in the bottle and budda bing, no more mess. I also question having this hose where it is because it will no doubt suck up clutch dust from the interior.
(2) the waste gate valve body rubs on the heat shield (at least mine does) to the point where its almost worn a hole right through. That means tension on that valve so I buzzed a slot for it to sit in so theres no weight on it. (3) those steel braided lines are torture on aluminum stuff! Even though I dressed mine up with rubber hosing in spots where it touched stuff, I missed a small area and it rubbed clean a spot on the valve cover! (4) best for last, almost had a cataclismic disaster! One of the bolts holding the exhaust manifold came out (yes, I torqued them to spec!) and that allowed exhaust to exit out under the heat cover that sits over the pipes. However, enough heat still got out to cook the valve cover gasket (no damage to cover) which caused it to leak, which I spotted while doing my usual inspection after each ride. It also partially cooked the 2 wire lead that goes to the turbo compensator valve! This wiring harness, from the factory, is not long enough to route anywhere other than directly to the valve,so, I will rewire it with more length and run it outside the turbo heat shield and along side the tunnel.
Thats about it, both sleds ran great, Bruce will have to have that smile on his face surgecally removed now! The biggest problem we have with both sleds is keeping those 2 stroke guys off them! Thanks for the help Sly........Sherm

He He HE!
Next week!
Next week!my txtx
well finally got to go for a good ride today
wicked is one word that come to mind still have the stock track on it and it will pull her self on to the grab handle quite easily.!
pretty impressed
my boost was right on but im not pulling enough rpm only at 8200
but it still pulls wicked and should get even better with a little tweaking
what else can i say but im frigging happy. hopefully it will just run and be problem free now and i will be as happy as a baby in a topless bar

wire to controlller
would have been nice to leave connection off of the controller wire so i guy could have got some good non split loom around it

Anyone get the prairie weight nailed down yet, I went out tonight and with 58 grams in my Hauck weights (I could weight them down? they are light in the tip and heavy to start) and was rev limiter non-stop.....everything else is stock MTX (20/40 gearing and 153" challenger). I have another set at 69 grams I am going to try tomorrow, I could put my 8BU's in but they are around 57 - 58 grams loaded....I know they will work out west but seem too light here?
FYI on the wiring that goes from the control mod to the turbo. I spoke to Eric at MCX and he said its OK to lengthen it if you want. I re-did mine and it now runs outside the rear heatshield and then through a hole near the rear of the shield, no more heat worries. Also, that vent tube from the airbox, chopped that right off to 2" long and put one of my finest chunks of Tshirt over the end as a filter, no more clutch dust! Sherm

Hey Sherm, which vent tube are referring to? Is this the oil tank vent or is there another? Just so I am prepared...
THX.
THX.
Its on the MCX airbox, same side as the tube that comes from your oil tank, only its right up front. The instructions say to take the hose out of the OE air box and put it on the front fitting, "This hose shall ventilate out in the atmosphere." After looking at it I figured rather than having that bottle I had attached to it and the possiblility of the goo flowing back into the airbox if the sled is rolled over, why not just have a short chunk of hose on it and cover the end with some sort of filter material! No condentsation can form in the shorter tube and also keeps the clutch dust out of the air box. Thats my take on it anyways.......Sherm
That hose is from the catch tank for the crank vent. If (when) your filter gets any moisture on it, it will freeze off and you will probably blow out the valve cover gasket, or worse . I think your first idea with the bottle was safer. I just have mine vented with a 2' long hose to the bottom, behind the oil tank so it doesn't freeze. Been thinking about a bottle for my inverted adventure days, lol

Thanks Sly! The only problem I have with the bottle is the crap thats in it will flow back into the airbox "when" I am inverted! I thought the moisture may have been from buildup in the hose itself rather than from the airbox. Should air not be sucked into that vent when the engine is running? I assumed the vent just went straight into the box and didn't hook into anything else, no? Got that turbo pipe rigged up, went with the one with the 90 in it, fits great and really dosen't need any cutting of the plastic around it. Now I can always have full power! Do you have your TORS disconnected Sly? Sherm

Just built our first MCX 180 yesterday. Took it out behind the shop for some "field testing" and it was impressive. Taking it to one of our local zones tomorrow to see how the clutching works.
Not too bad of an install, but instructions were a little vague...
Nice kit though and the fit was clean.

Put the 69 gr base Haucks in and much better, going to add a little weight and they should be bang on for around here. Boost was consistent, around 7/8 lbs on the gauge and backed the rod out one more turn to see if I can get it to read around 6 - 7. One question though, I had a "overboost" on my way home, it was over 10+ lbs I let off worried about doing damage took it easy the rest of the way. It would show boost on the gauge as soon as you gave it throttle.... I assumed TCV valve froze up? As it seemed to be back to normal after sitting in heated garage for an hour. Anyone cover the valve up to protect from snow/ice? ? Any thoughts?

There is a sensor (I think that is what it is) that comes off the wastegate, off that there is a box with a vent spout.
That seems to get burried with snow easily I'm wondering what that is and if I should run a short hose off of it to a spot that might not get as snowy.
I have it bolted beside the air intake currently.
Anyone have a photos of where they put theirs and what it does?
