NEW Hurricane Intercooler install & testing! Should you install a new intercooler on your 900 turbo? 

Well isn't that just a fantastic comment! Thanks you @sled ed, much appreciated and glad you're enjoying the content.

Thank you! I agree, it sounds awesome. 😊

Thanks @Mike Guliz, much appreciated!

I can’t wait either! 😁

Amazing! Thanks for the great info Dan!

Thanks for the kind words Mike, much appreciated. I’ve never compared the GPS data on the GoPro with anything else but I would guess it’s sufficiently accurate for what I’m using it for. I think it’s a mistake to only look at top speeds when debating if the Hurricane upgrades are “worth it”. Top speed runs are fun every once in a while but that’s not typically what I’m doing with this sled. The other 90% of the time is on the trails and THAT is where this package really shines in my opinion. Unfortunately that is a little harder to quantify in a video so we tend to rely on the top speed data to help prove things. Bottom line is the best way to know if it’s worth it would be to try it. “Worth” is very subjective as well. Looks like I’m going to be joining Jesse on a ride soon and I’ll be sure to let him have some seat time and hopefully I can hook up with the other half of @sledaddicz soon 😊 Ultimax belts is what I’m running and what Dave recommended 👍🏼

Hey Mike, Agree on the ole reliable Garmin when i want my most accurate TOP SPEED MPH, and my stalker radar gun is even more accurate since it sends a constant signal to the object, vs a GPS which take a longer period of time to get a signal from the sky. But in a longer haul top speed run we find them both to be within .5 MPH of each other. Definitely not good to try to compare any one day's speeds to another day's IMO. That never seems to be accurate, even when i go out in similar conditions on same sled it can widely vary in top speed. With these 900r's I find the clutching RPM is by far the most important number to be sure you are hitting. I have seen 10mph differences between 7800 and 7900. If anyone is revving below 7900 solid on very top end, you will be slower on these 900r's. With that being said, Dave may very well have "tuned" his ECU for a MORE ACCURATE RPM number on the gauge, and have heard he has also tuned the MPH number top be closer to correct, so those would be first questions for Dave for sure. I have gone back to ole reliable PL/PL QRS spring which i have loved since 2015 on my 12004tec, as I'm a Muskoka corner to corner guy and this spring brings that type of riding to life. It's a 231/303 rate, so has the same finish rate as stock Green, but a higher start rate which holds the RPMs up down low, and will give a slight overshift on the hit, which IMO is how I like this sled to run. As for the pDrive i have gone back to stock spring(170/300) and stock spring cup(lots of this i have videos on my channel) since my testing shows stock spring cup does not impede top speed(full shift out).... however I ditched the 897 Mach ramps with the idle notch for Launch control as they just never would work well with my stock engine. Been running Dalton adj weights for years in all my sleds, and the 901t has worked well for me with the stock Mach Z. For my setup running the 75g 901t ramps, with tip OPEN and heel loaded with the largest 4.7g slug(79.7g total weight) is the sweet spot when using stock 571 belt along with stock helix and PL/PL as mentioned. For amazing corner to corner and little lake running, i will back out the slug 5mm out the heel, and this will overshift even more when running the tightest trails making it a corner to corner animal. For bigger trails I keep the slug bottomed to keep top rpms in check. I spent all last winter working with the Ultimax, and have loved them for years. But at end of last season I blew one bad with only 1200 miles, taking out pan(see my channel for video) and since It was always a struggle getting rpms correct with the 821 Ultimax(since it revs 200 LOWER then stock belt) I decided to try a stock belt this year, since my bud beat his 900r hard all season with 2800 miles on his stock belt and never skipped a beat. So I believe longevity is best with stock 571, While consistency of rpm is best with Ultimax. 571 is dirtier then Ultimax as well. Ultimax may be a faster top-end belt in the end, due to least slippage and shorter length then stock belt and even shorter then Gboost, but in the end I think stock belt is a real tough muther and hoping it lasts. BTW add a PEFI belly guard to have peace of mind guys(also in that same video). In the end I think far too much talk has been placed on top speed and tune/ECU HP numbers. This is why i have pulled away from DT forums(which i used to love). I think boost PSI numbers are a better way to discuss one tunes power to the next, I realize Dyno numbers are a testing tool, and Daves Dyno has served him well. However when novices do not understand how each dyno is different from the next, and each guy sets his up in his own manner, the discussion gets far too convoluted on forums and then all the negative comments come out. I don't blame Dave or any other tuner from backing away from forums. Bottom line is these Doos, ever since rMotion, have been a slow chassie and skids, but we got the best ride in the business BY FAR. My Winder was a rocket top speed, but rode like a dump truck in the big junk around here. Mach Z will never make a ton more top speed in trail form, even if you add 35HP. Going from 117GPS to 122GPS on ICE perfect day would be about best to expect. Now drop that chassie down, change out drivers for angle of attack and all the sudden you see big speeds. Always a compromise somewhere as you guys know. This is why i mentioned I'd like to see Dave's ECU vs stock Mach more in a side by side roll-on, this would be a better way to quantify the difference in stock vs standalone ECU. Hopefully soon I will get up there and we can try it. I think mine runs as good as any stocker will having the clutching setup, and Im certain Dave's ECU tune along with the supporting bolts on's will walk very hard on my stocker, as it should. Maybe top ends won't be hugely different but that is to be expected. Is that kind of difference worth the cash? Well that is up to the buyer. I think for some it's worth every penny, while others will say it's not. We used to get tunes for $450USD or so for Winders, but with the BRP 900r, Doo went to the high encryption "super car" ECU which is a marvel in itself, and while it does a great job protecting our stock engines, it wont allow much once it sees anything it doesn't like, IE: AIT is one of many I'm sure. So Dave along with other perf outfits are taking the Standalone ECU approach which is never gonna be nearly as cheap as a simple flash. Guys should be happy we got these aftermarket outfits giving us these choices, and not bickering about them IMO. After my Hydro went out all last night, i guess I really needed to type! HaHa. Once again great work on video! 'rockerdan'

@berttracy90, yes I had it checked at the dealer and they told me it didn't need calibration but I have heard from others like you where it did make a big difference. Gonna have more Hurricane goodies coming this season...stay tuned!

@Baydog, I think you may have missed the point of the video. The point was to show a before and after of JUST the intercooler. That's the only thing that was changed between the runs. The lower RPM's during the first passes seems to be due to the higher intake temps. The intercooler is around $1600 CAD not 5 or $6K. I'm guessing you're making reference to the ECU + tune but that was installed last season on this sled and wasn't really part of this video. I'm sorry you feel this somehow affects my credibility but as I mentioned in the video, I paid full price for the ECU, clutching, gearing and muffler last season because I believed in the product. Also, I'm not trying to sell anybody here. Just trying to make entertaining and informative sledding videos.

I don’t think 200ish rpm make much difference on a 4 stroke sled like it would in a 2 stroke. The hp difference at the crank between the two rpm’s is probably on a few. Also I have basically the same set up on my Mach and you could have the best clutching in the world and still wouldn’t come close with a stocker.

Thanks again for the kind words @rockerdan! Absolutely nothing was changed other than the intercooler between the runs other than the sled may have had less fuel in the tank during the second set of runs. Dave is most certainly a wealth of knowledge when it comes to making fast sleds. A side by side run compared to a stock Mach would be great but I need some traction improvements before doing some ice runs. Currently running the stock 1.25 with only 96 studs. What are you running for studs? And absolutely, overall this is such an amazing riding sled. Also have a brand new Gen5 Reny in the garage but all I ever want to ride is the Mach 😁

@@BeaverTailToys My one buddy has a new G5 MXZ XRS with the big 10.25 gauge and I just love that thing on our tight twisty Muskoka trails especially when it gets pounded out! It makes me feel 16 again! The Mach Z I find is more like a Caddy and well suited for the bigger wide open super highways up north. Once we hit our lakes the Mach let’s the 850 know who’s boss💪🏻. I actually like running less studs as I tend to not drag race. For top speed runs less is better having less rotating mass. Sharp studs in this case is more important then quantity. I trail ride mostly so I like the woody’s mega-bites for their longevity and less prone to bending with their square body. I only run 120 in a 2/3/2/3 pattern. I like a longer stud but not overly long and opt for a 1.45” length when running a 1.25 lug track. I like to see what my sleds will do at their very top, so longer hauls on fastest surface is when I like to get out the radar gun. But for your testing of tunes and go fast equipment you are doing it right trying to get those back to back similar condition runs. I try to do this exact same testing with all my clutching. Helps a lot living right on my lake here all winter and the neighbors all know when I’m trying a new clutch combo. Lol 😆. Hoping to get back up to your neck of the woods to ride around the Sudbury trail system in the next few weeks. We should chat more soon brother. Keep up the great work.

Thanks for the great info Dan, much appreciated. I just subscribed to your channel, didn’t realize you were in the Muskoka region. Definitely send me a message on FB or IG and we should hook up for sure. I’d love for you to try out my Mach and get your opinion on the difference.

@@BeaverTailToys Certainly will brother and thanks! Not on FB but I am getting alittle better at IG, LOL! I will have to figure out where to send a DM to you on there this week! Last time I rode French river area was 2006 on my Apex, we did a trip up to NB then looped over to the French river bridge(was quite new at the time) and i still look back at my old low res photos of that awesome trip. Cheers!😁

@serge basque j’ai ben hâte de voir comment sa va I allez avec le programme de 250HP! 🤗😈

Nice! 👌🏼

@sage mcmullen thank you 🙏 The 250 kit has a new turbo, new pistons, rods, studs and head porting.

lol, is it fast? 🙃

Nice to hear the BRP updates helped for you. I'd say my RPM's were not really stable either before the upgrades, kind of like what you are describing.

@roger Hamilton, I’ve never watched them but clearly they have great taste 😊

@Daniel Gagne, yep that is what Dave at Hurricane tells me. Obviously the difference might not be as big but still a worthy upgrade.

I don’t think it’s really that weird, allot of factors to compare there. Clutching, gearing, traction (studs), air temp, rough track etc…This test wasn’t so much about what the sled can do too speed but more about some direct A-B testing. I hit around 190 last season before the intercooler swap in better conditions.

@@BeaverTailToys I am not convinced you made any gain on the intercooler as conditions would have made the change in speed. The change to analyze would have been what the fall off would have been compared to stock. Showing us the IAT's from stock to the new cooler would show if it is worth 1600.00 I have been told that it takes about 8-10 long runs before it starts to pull timing and fuel utilizing the stock cooler.
