Tech Tues | Ski-Doo 850 E-Tec Turbo | Tuning

[@jakeshupe79]

Awesome job on the tuning. I've got two rides on mine with the stage 3 and loving it. It out does my alpha with the silber turbo on it at 7 psi boost.

[@BikemanPerformance]

That is awesome!

[@powderaddicts6364]

Question! I've got a gen 4 2020.5 factory turbo and am looking for recommendation on what i need to run the stage 2 tune. does the torquelink come with the stages in it or is it an extra cost for the tunes after the torquelink purchase? and is there a recommended stage to kit for clutcing? Thank you.

[@ianstuart7395]

Man Doo is really pushing the envelope. Props to bikeman and Doo for allowing people to get into the turbo game for reasonable cost over stock.

[@jlo13800]

i wonder if bike man performance could turn up and port a Napier Nomad flat 12 2500 CID 4000 hp 2 stroke like this:kzbin.info/www/bejne/pYPTg4mBmbisZ9k

[@jlo13800]

now thats a turbo 2 stroke but a little big for a sled though!!!!

[@Trumplican]

Are you guys doing long pulls on the dyno when you make these numbers?

[@BikemanPerformance]

We do multiple pulls to get consistent results. if results aren't consistent, we continue to optimize the tune until it is consistent.

[@Trumplican]

@@BikemanPerformance yes of course but i mean long pulls as in staying at wide open throttle for about 10 seconds. A quick run where you dont hold wide open can show promising numbers but you dont know if its going to hold those numbers. Many pipes these days will show great power on a short pull but if you hold it wide open more than a couple seconds the power drops significantly. In the real world people are going to be holding wide open whether racing or crossing a field or frozen lake or a straight stretch down the trail. So I'm just asking if you do long wide open pulls to simulate real world use?

[@brandonvandervelde2695]

im at 1300 ft. say i wanted to run a 50/50 blend of 110 and 90 rec. in the future is this turbo capable of 7 8 9 10 psi with higher grade fuels?

[@adammarkin8371]

was it even broke in before you did a dyno test?

[@ckfarmz]

What mountain areas are u guys riding and testing in?

[@BikemanPerformance]

We test in colorado. But 95% of our testing is done in western Wyoming, Yellowstone, Idaho. Wherever the riding... i mean testing is good haha. We have a full time person testing sled and sxs components.

I'd like to see one of these run max boost on E85 racegas 😁💥

Wow skidoo killing it everyone else not even close

[@TrakSpock1]

Oh yeah, Ski-doo killed plenty of crankshafts in the isoflex grease era. New Ski-doo 850 engine, with dedicated oil passages to ensure long engine life. Ha ha! Ski-doo actually advertised dedicated oil lines when the 850 engine debuted.

Rotax is catching up to detroit diesels, EMD and fairbanks morse OP big 2 stroke diesels, 4 joke runs and sounds like crap anyways. here how to get a 4 joke to run good. convert it to a 2 stroke like this VW 1.9 diesel u-loop charged poppet valve 2 stroke:kzbin.info/www/bejne/p6DWcp-imM1rick

[@Icutmetal]

Bravo, guys!

[@jlo13800]

can you imagine scaling an 850 ETEC rotax to over 600 CID 10L or more inline 6 with turbo! Achates power with there OP 2 stroke is making progress to.

[@Eduardo_Espinoza]

What do you guys mean by "higher weights?"

[@JoelArseneaultYouTube]

Since you didn't get a response, and I saw your comment. I assume they are talking about clutch weights. They are one of the things that control the "shifting" of the CVT. Heavier weights have a tendency to cause quicker upshift. They may be fighting with trying to maintain grip on the belt and find it necessary to use the heavy weights. The quick upshift could be causing the engine to lug down a little until you get a little speed and rpm.

[@Eduardo_Espinoza]

@@JoelArseneaultKZbin after extensive research on 2t engines since then, I 100% believe you.

[@JoelArseneaultYouTube]

@@Eduardo_Espinoza Excellent. I used to work on drag racing snowmobiles way back in the 90s early 00s. We had some Yamaha and Polaris sleds. I currently have a KZbin channel and do most of my work on a 2t Kawasaki 1100 triple. I recently acquired a few other interesting engines as well.

Why does everyone else have a turbo on there tuck or anything and dont need a new block? What is you point?

I'd like to see somebody swap one of these into a 129 mxz

haha you aren't happy with a oem turbo? haha

[@shperax]

@@BikemanPerformance So much boost and gas are wasted. Add in some valves like Stihl does on 2 strokes and you can crank up the boost to some real numbers.

[@hdkapa]

unreliable two stroke where you need to rebuild the engine 4000 mile so is there a 2000mile after tuning ??

[@Icutmetal]

Huh?

[@allenseferagic9426]

Lol you wish you had one

[@jlo13800]

2 strokes make more antimatter at times and the antimatter hits the cylinder wall and creates gamma rays wich split into more electron/positron pairs, (a photon is a virtual electron/positron pair in the virtual particle flux of the aether or ZPE) lightning is one of the most powerful 2 strokes known to us, Our 2 stroke go from hundreds to thousands hp but lightning is a terawatt 2 stroke and destroys what it hits! A ligtnikng stroke created gamma rays emp which split to electron/positron pairs. Also ball lightning EVO's electron plasma vortices are formed witch act as high energy roller bearings which lubricate/guide the stroke and can can rolling and are known as ball lightning, they are very hard and dense and also hot. they are capable of nuclear transmutation and can be used for machining and forming parts to make a better more durable 2 stroke!

[@snoogboonin]

Increase power like this at your own risk.... more power=less reliability. If you tune this thing, say goodbye to your warranty as well.

[@Icutmetal]

Matthew Humenansky No shit?

[@jlo13800]

@@Icutmetal thats true with anything. I doubt a 4 joke car motor would last under high boost continuous duty. Lets see one run tilted in any position with just a synthetic 2 stroke fed to it. let the experiments begin!

How do you make a engine less reliable than a Mazda Rotory?....turbo a 2 stroke lol!

[@Marcmustang]

🤦🏻‍♂️ more reliable than a stock polaris

[@fargonianproductions2767]

Summit 800 H.o. In my experience, I shave had no problems with Polaris

[@jlo13800]

Well high energy photons are formed in some 2 strokes. we know that a gamma photon is an electron/positron virtual charge pair moving through the aether or quantum vacuum/ZPE. when this photon goes near a nucleaus in the cyclinder wall or hits another photons electron and positrons are created, the positrons are antimatter and annihilate with electrons that make up parts in your 2 stroke and they dissapear into more high energy EMP photons, this can cause wear if this overlooked and make the engine go out of tolernace. Dont forget evey lightning stroke is a 2 stroke and can make gamma emp witch splits into electron/positron pairs, a few hunded to a few thousand hp comes out of our 2 strokes where lightning is a terawatt 2 stroke!

[@jlo13800]

Absole BS there have been turbo 2 stroke diesels for years, i got an 8v92 detroit 2 stroke turbo silver that run on any oil, she does good on a few gallons BRP XD-100 but its not cheap. Lets see a 4 joke run under long loads like a Clarke uni-flow 2 stroke of Day loop charged 2 stroke! heck some 4 jokes can be converted to 2 strokes poppet valved u-loop charged like this VW 1.9 diesel 2 stroke conversion :kzbin.info/www/bejne/p6DWcp-imM1rick. I keep my rotary on nothing but Amsoil Dominator synthetic 2 stroke oil! not 4 joke multi-viscosity crap and runs great.
