Only guessing based off of the regular xp turbo: the TRE might have a lower low gear. If tou’re doing rock crawling, the lower low gear is better.

The Pro XP doesn't have the lower gear like the TRE to the best of anything i can find, ( I would be ecstatic if it did) and the TRE also comes standard with 30's. But the Pro XP (PXP? XPP? what are we gonna shorten that to? lol ) has stronger everything else, yes.

The rear gearcase seems to have remained the same as the Turbo and S models, so the gear reduction options may remain the same if you wanted to go that route (I have not confirmed that as the Pro XP schematics aren't available yet). But if the strength of the drivetrain is your main concern, then the Pro XP will be the better machine it seems. We'll (this forum) find a way to do gear reduction if we need too :grin

And you probably don't NEED the extra power.... but you won't regret having it either.

 

The Pro XP is on my wishlist because of it's 6" longer wheel base. (and the boss lady really likes red) 3500 miles on our 17 R&T. I'll wait until this time next year before I buy unless Abernathy can offer a great deal sooner. Plus I want to read some reviews before I spend that much.

Oh yeah, forgot about it being a turbo. 91 octane makes it a pita. I'd prefer not to have to fill the 40 gallon fuel tank on the toyhauler with 91, particularly when the generator also uses this fuel.

 

IMO, I would never buy a new model year machine from Polaris or any other manufacturer. They are always working out the bugs for at least two years on a new model; especially because this model has a lot of engineering upgrades!

 

Reduced Belt temps 100 degrees! ProXP

I like the Pro, but I would miss the lower gearing on the TRE. I know this is a long post, but some of you might find the info helpful.

Something I picked up on is they claim to have reduced the belt temps by 100 degrees!! Increased belt life 8X! All that from a new clutch design on a turbo seems impossible to me.

Here is my opinion on how they did that. Looking at the new clutch I don't see anything that would increase airflow that much. Marketing guru talk that eludes to something else. The 20 to 50+MPH sweet spot they claim this rig has is a clue to whats going on. Its a low geared high power corner to corner speed demon. They are spinning higher RPMS to move more air through the clutch and that is an good indication that gear ratio is likely lower than a none turbo unit.

I'm sure it will have plenty of top speed. A lower gear to build boost makes sense. Lower gear, higher clutch speed = cooler belt, easier to turn that lower gearing and less stress on the belt.

I have been towing an expedition trailer with up to 600lbs of cargo in the Colorado mountains this summer. Using an articulating hitch to tow equipment up impossible grades. Also moved some 1200lb equipment up and down steep mountains at low speeds to remote areas. After a few hundred miles of this my TRE needs some maintenance. Other than front diff seal leaking a little it has held up to the abuse. Rear tires are half tread.

How did I make the belt survive? A blower to cool it and a HD belt. HW wide belt from 2018. Updated design is out now. Not a plug for the belt, but a blower motor should be standard issue on all belt driven machines IMO. Night and day difference in temps.

Not sure I could do the same thing with the Pro. See how it performs for a year. Then I might want one. It is a nice machine with a lot of new updates that make sense.

I agree with your line of thinking. I myself installed a MTNTK Blow Hole from the start and used a Hunterworks Thick belt with great success. In videos I have proven that the MTNTK Blow Hole is more efficient up to 5000rpm then the mechanical clutch. Plus the benefit of a cool down period when you are off the throttle is a huge reliability win.

 

Before you start talking down the new Pro, you need to do your home work and be informed.

I don't see anyone bashing the new rig. It is natural to question the next design of any product.

Great video. I like how he admits some of the design problems in the past and how they have improved the design on this version. No significant change in airflow, just a better box design for heat exchange. That box with a belt blower fan would work super efficient! Very well engineered, just missing the fan that blows air to critical spot he talks about behind the primary even at engine idle. That would be my first upgrade on this rig.

 

I got more from the video on how they are forcing air behind the clutches. The fins on the back are really great. Will get rid of lots of heat. Did you note he said the exhaust air is not warm but hot. They have totally redesigned the clutches. I really like want I see. Really a next generation of clutches. And listen to his talk on all the hours of work they put in on this. Do not think any additional fans will be needed. Might only restrict the flow.

 

I agree, its a better clutch design. They should have done this about 5 years ago. Competition from other brands such as Honda may be the reason for all the extra efforts to fix some of the problems now. The public demands a level of reliability that is in line with the price paid. Not sure we have had that from Polaris in recent past.

Hard to find anyone who hasn't had a belt explode after a few hundred miles. I'm shooting for belt changes every 1,000 miles instead of constant replacement on the trail. It's possible belt reliability might finally be a reality with this new design. Time will tell, but hate to hear him talk of easy belt changes as an improvement. Need more talk of longevity of said belt and a warranty like tires for your car. Won't happen, but it should be that reliable. A 500 mile warranty for the belt should become standard for all brands IMO.

Look forward to seeing how these new rigs perform. So many upgrades/changes. Lets see what happens.

 

I really don't think you're going to see a belt warranty on a high-performance machine. Most belt failures are caused by misuse and abuse, and it's really easy to destroy one if you do dumb things. Just look at the number of people who say they don't break-in a new machine properly, but just hammer it. That means the belt was never broken in either. My machine has ~750 miles on it and my OEM belt looks brand new. I broke-in the machine and belt as Polaris dictates in the manual. I ride aggressively, but don't do stupid things to the belt. Also clean out the clutches often. No reason you can't get several thousand miles out of these belts.

 

Here's my thoughts coming from the XP1K HLE which is identical to the TRE mechanically. The price of the TRE right now I believe is too steep for the chassis it is being offered in. Chain driven reverse, weak snorkel gear, out of phase/balance prop shafts, and turbo xp front differential don't particularly turn my crank for a model that is selling so high in MRSP. I've broke all those parts in the last two seasons. If it was equipped with the RS1/TurboS Front Diff, Turbo Transmission this would be a much better platform then it is now.

IMO you are better off to pick the Pro XP and set it up with the Mountain package(Well relevant items from that package for you). Price wise you are in a better chassis with better parts.

Just my opinion.

 

I saw your video of the blower before I did my setup. I went with a modified bilge blower I cut down to fit inside the top of the intake tube, so basically the same thing. Been great for few hundred miles. I also clean my clutch after a couple hundred miles of dusty trail. Always find a little dirt/dust in the cover so I hose out the entire clutch and even wash it while idling to reduce any wear from the dust. Yes, I get wet from the clutch slinging water, but it is clean and looks great after a quick run down the road with cover off to dry it. Could add additional filter to the clutch intake, but the frogskin does keep out the big stuff.

There is one thing I noticed with the blower fan that was a great indicator of how good it works. It takes so much longer for the engine to reach a temp where the fan on the radiator even comes on. In cool temps it never comes on because the belt blower is cooling the engine behind the primary clutch so well. I will never do without one again.

Like your coverage of the belt info. Its a great way to get the most life from any belt and the rollers are a must have item.

 

Its apples to oranges in my mind. If you dont plan on seriously crawling any longer or maybe you dont use your TRE to its full extent the PRO would be fine. If they come out with a PRO TRE then that changes things.

I sat in the new pro and also ran it a bit right out of the crate at my dealer. Im not too impressed. In fact I bought a CanAm X3 that day to add to my fleet.
Its like a cross between the wide body of the X3 and the current XP chassis to me. Power doesent feel like 180 to me. The S felt like a better machine to me because its at the end of production run. Its been refined.

 

I sat in one myself yesterday and spent 30 minutes going over it mechanically and visually.

Good: -The seats are awesome!
-I like the gauge cluster location and readout, more car like and easier to glance at for quick readability.
-Updated clutch should get more life from belt.
-It has updated driveshafts, all visible u-joints are the larger size easy to get from Spicer.
-Rear drive shaft has balance weights on it. After trying to replace the TRE tiny front u-joints this is an improvement worth noting.

Bad: -No winch.
-No low gearing, same as XP.
-A arm ground clearance not as good as TRE, but if they use this platform for the next TRE design that might change
-The doors are flimsy and the flip switch gear seems cheap.
- Overall fit and finish is not a quality feeling. Top storage box on passenger side hits roll cage before fully open. XP platform is better IMO.
-My knee hits the center console in a bad spot. Smaller guys with narrow shoulders should be fine, but if your a big guy like me who has had knee surgery the XP is better.
-Roll bar feels weird, like it's laid back too far.
-Will need specific winch mount, bumpers and front back windows to fit this unit. Everything has change, so nothing off your old rig is going to fit.

Been racking up lots of miles on my TRE past three months and the only thing I really like more about the Pro is the seats.

 

-Updated clutch should get more life from belt.

The belts are outlasting the clutch. Several primaries have literally exploded on them so far. I for one am disappointed in the machine. Seems almost to me like the Polaris finance guys forced them to shove the unit out the door without addressing fit and finish and other trim levels of the machine.

 

Did you all see this thread by Crowdog on the XP-Pro for crawling?

First thing that jumps out at me is the doors on the Pro. Ran into a guy at Silverton just a couple months ago in September. His brand new Pro was 1 week old.

He had the optional full size doors and was covered head to toe in mud & dust. He was really pissed about how bad the doors fit and how much dust came in the vehicle. He had both front & rear windshields.

 

Funny how users think front and rear windshield should stop dust, when used together they create a low pressure area that draws in dust.
