Can An ULTIMAX Belt Make This Sled Faster? 

I totally believe the belt made that much of a difference! I put an Ultimax belt on my 2016 ZR8000 137 and it felt like I gained 20 HP over the Gates belt I had on it !! Ultimax is the only belt I will use on all my sleds, thanks Pete 🙂

Amazing. Keep the videos coming Pete. So much fun watching! CHEERS!!!

Adjusting the belt deflection should have been done first with the belt that was on it and see how it runs. Then put the new belt on and run it to make a fair comparison. If the belt that came on it was worn out any new belt will show better performance. Even a factory Ski Doo belt. This did not show that the Ultimax belt is superior.

Good morning Pete great sled video. Keep em coming. 🍺🍻 pitter patter git at er.

Nice one! I rode with 3 Ski Doo's last year, all 850's only a year or two old, one guy heard a noise and upon checking it out at the dealer, it had a bad con rod bearing! While at the Dealer there was another guy there that just blew his engine also!

BRP belts stretch like crazy with use. All I use on my 850 are the XS 821s. With the 150 / 300 factory primary spring and Goodwin 35mm pivot weights with 1.7 gm weights, # for 3 the clicker setting the sled hits 7900 - 7950 constantly and holds there. Love the channel!

Stock manual says the bottom(valley) of the belt rigs should be at the top of the secondary sheeve.

It would be interesting to compare belt temps between the two. But yeah, a compression test might be in order.

Man Pete i love the channel!!!! Great info love all the little sayings also. Keep on keeping on.

I am sold on Ultimax belts, Everybody likes going to the MAX.

25k SUBS...so close...LET'S GO PEOPLE

Ultimax for the win on that skidoo

Another great video. You have me convinced now! Changing the belts on all my sleds. As soon as you start selling them, I will order some. If you are not busy this weekend, you and Billy and the young lady should head to Evansville to watch the oval track sled racing. It’s a great time, would be some great content for your videos. And the beer is cold!! You can either watch from inside or outside. Hope to see you there. Cheers

I put up the 60" big screen and paused on your tach. 1st belt i seen 8200 WOT and touched 8300 at 141kmh; yer pulling 200~300 rpms over the power peak, about 4hp less to be precise. 2nd belt (XS) I seen 8000 and pulling right on the power peak. On the 1st belt, IF you would have lowered the clicker to make pull at 8000, then the sled would have been faster pulling on the power peak rpm. The 850 makes 165hp at 7900, and, 165hp at 8000. [flat power peak] The difference between the two is 1.8 lbs less torque at 8000 rpms. Pulling at 8200~8300 [1st belt] yer pulling at about 160~161hp. I'da changed the clicker on the 1st belt.

Nice improvement ! Taking that drag out of the track helps too , Nice Work 😎👍🍺🇺🇸🇨🇦

Hey Pete I think u just sold me on the Ultimax baby!!! I gotta have one for my Winder now. Nice One!

I had to do an extensive clutch alignment on mine. I was blowing belts like crazy. Grip n Rip racing products. Watch the videos and buy tools. Went from blowing belts to 2 yrs on the same belt.

Damn good gains there Pete well done! Take it to the max!

You didn't say tickety boo in this video! I've been walking around the house for a week saying it and even singing it in anticipation of the next video 🤣🤣🤣

Great video having a cold one in garage we need snow ordered some merchandise from yas this week can't wait to get it thanks for the video

It's best to rebuild the top end of those new E-tec every 10,000km, so it's definitely due. Better to just do it when you can, rather than it leave you stranded somewhere. Not to mention likely costing you a lot more money if you let it blow.

Going for a test run makes the best videos ✌🏻 cheers 🍻

Prior to putting on a new belt, wouldn’t it have been a test to adjust the deflection first take it for a run and see what kind of performance difference would make then put the new belt on and see the difference

Nice one!

If the belt is too loose (too much deflection) it will never get pulled to the bottom of the driven pullley therefore limiting top speed.....I would bet the deflection had never been adjusted on that sled since it was new.....on the other hand if the belt is too narrow (burned up) you will never be able to adjust the deflection to spec. A new belt will always benefit performance but if you don"t keep it adjusted it won't last long. I keep my belts at 1inch to 1 1/4 inch.....deflection when pushing down on the belt with my thumb.

I’d still blow the clutches out an check them out . And everything else like the power valves . Clean it all for the gentlemen

I picked myself up in 18 XRS Renegade with the 850 E-Tec and boy those things are finicky! The plugs follow up pretty easy if you're not careful then they definitely don't like any additives in the fuel! Changing out my first set of plugs already and you have to sequence them because of the injectors! Super important or they'll be garbage in a minute

🍺🍺beers time

Very surprised that thing don't hit 100mph, maybe it needs more room to get there, but then again it does have a long heavy track Without a doubt, he belt sure helped but it didn't give all that speed, you change too many variables. I would have adjusted the belt tension, then done a run. Then done the belt change, the the track/sliders adjustment. When we racde Ice oval and snowcross in the late 60's and 70's, we would only change one thing at a time, document it, and carry on with the next thing. Performance tuning is knowing exactly what does what in a given condition. Also that ricky racer throttle bliping cuts belt live by about 1/4 of it's life. Each blip closes the primary, putting excess strain and wear on the belt. Years ago (60's, 70's and early 80's), before accelerator pumps on carbs and fuel injection, it was done(especially two strokes) to help prevent lean bogging when going WOT. We done a bunch of tests on my 76 Ski-doo 250 TNT RV, with Mikunies and our 75 245 TNT fa . The mikunies got rid of the vapor lock stumble Smooth throttle control , easier on belt and less track spin(spinning track is less speed)

check the clickers too. he should be touching 8k rpm. if he’s a big guy might need to adjust

I like the dragy data! Cheers!!

Nice one ! ☃️👍👍

I want to move to Canada after watching you 😂

My 2020 600 ace was doing 65mph so somethings wacky with that sled.

It’s been a minute since we been down the trail! Cool

Put that sled outside as a salt lick for deer.

Every pass made is also packing down the trail so that helps too. But I will be looking for Ultimax belts for my machines Thanks Pete CHERRS FROM MANITOBA

My Wife works for Timken, I didn't know they made belts? Maybe I can get a discount?! 😮 But seriously, I think someone messed with the clickers in the Primary, blew a belt and never adjusted the secondary for proper fitment..? Ask me how I know, I did it myself, thinking I knew how to adjust a Clutch.. Mine would rev too high to fast and never engage the Secondary... 😂 Live and learn!

My 03 MXZ 800 (zx chassis) will do 165 km lol. Nothing like the old iron.

Take er to the Max! 😂😅

Awesome some ski doo content!!!!!

This sled is beat on. Not taken care off, clutches are dirty and never been cleaned it looks like, belt deflection is way off. 7900 is peak RPM.

About time!!! We need three videos a week!! ❤ or just drinking videos!🤣

Why is it I always see Ski-Doo's blowing belts? Have hardly got to ride this year and already have seen 3 on the trails with blown belts. Ultimax belts are my go to belt as well. They have held up very well.

Nice to see ya workin on a real man’s sled for a change 😂. I think that sled sounded really shitty for an etec like it had a burble at idle. Could be plug wires arcing on the plugs, but a new pair o plugs would certainly improve that. Another thing we always do is Hi Torque rollers in that secondary, they are likely gonna fail on that 2020 sooner than later ifyaknowwhattamean - Great video, and thanks for getting me hooked on Ultimax belts. They Rock!

Didn't think a new belt would make that big a difference. Keep up the great work buddy 👍 RNDH 4 LIFE..

Decent!

The new skidoo's have problems with blowing belts.. i got a 03 skidoo rev 800 no issues, i run a ultimax belt and got 100km on it between two seasons lol. I keep the brp one as a back up tho

Why didn't you at least try changing the belt deflection on the belt that was on it first? Could have made gains doing that to.

another great video thank you for sharing be safe have a great day and love the videos and God Bless

100 mph is a rush , 135 to 140 mph , wear your Superman Underwear Buddy ! Wish I had a machine that made me need Super Hero Underwear , 100 mph fast ? Bust out the Wonder Woman Underwear , let’s Ride !

the secondary clutch is cracked on the outside

wow you sold me

Not much snow in Massachusetts. How much snow do you have and has it been a good winter for you guys

Little fine tuning with those clutches and reprogram that ecu and then the dangle part would improve.

Awesome brother thanks

I feel like there's definitely something wrong with that one my 850 skidoo will do about 115 mph on top

All the ultimax is going to do is going to mess up the clutching shift rpms.

🍺🍺

My old Mxz 600R would do 165 km all the time. 850 should hit 170 - 175 km / hr, My 2023 Renny Xrs 900r turbo hit 185 and was still pulling, should hit 190 no problem, no mods.

Love the videos. Pete had kinda same prob with my 02 mxz 800 renegade. Zx chassis. I think from what the web says it take a xs509 i think can u confirm that bro?.

Nice video

you should have cleaned the clutches on it. And then tested it. I bet you would have gained more.

always ran oem belts on both my 98 vmax 700s. think ultimax would be good?

Put an ultimax on the bravo and see what you can get out of it.

it would be interesting to see what she gains in a top speed run

Im sadend i thaught you were better then this but your tryin to push ultimax belts because @ 753 i saw 141 on a worn out spare skidoo belt and @1737 i seen 144 on a new ultimax

Hey what is the name of the app that was used?

What is that app u use for speed and rpm

Can you give us deals on belts ?

30 day warranty?

Seems real laggy outta the hole ?

Honestly that sled should pull 160 like nothing

Pete is the Horseshoe lake speed races on do you know . I'm from mckellar just up the road. I've got a T- shirt for you please bring me a 3xl Rd&DH T and a hat I've got LooT

Hope he didn’t pay to much. Filthy mess. = minimal maintenance

After you do all the things , go fast things , the only thing that can make you go fast overall , is Beer ! Wanna Bet ? Looser buys more Beer !

ultimax belts suck mine blew after one drive
