Watching the swedish people on snowmobiles is a work of art they don't have a bone of fear in their bodies. Hard to find on RU-vid with the language diffrence but it's a treat when you find their channel
Rick I sure do love that turbo project you have there. A real labour of love my friend. Would really be great to get to go out with you to the mountains next season to see it perform. Another great video from DIGIT9😊👍
Man, I built a few hill climbers back in the day, loved the smell of AV gas and the raw power. But, damn I spent a lot of time and money on these things.
@digit9 could you go over the VEP on that engine? I recently got a hold of a PSI 925 and the guy cut the tubes and I have no idea where in the world they go to. Going in a Polaris Gen 2 chassis this fall!
What garret is that? 3071? Nice build! I had an switchback assault with a kpa 2873 on 18-19 psi, it was scary fast. My 300 hp apex is a saint in comparrison lol.
Nice build!! I missed some videos and I am sorry for that. One question? How do you live the turbo?? I have an old 800 Polaris and a old RX1 I would like to play with. My buddy's run blowers so I would like to try a turbo. Great sound from that engine.
@@DIGIT9 ....Nice is there an issue for the oil temp at any time? I figured you had something like that setup but I was not sure? Never seen a sealed bearing in that area so I was wondering. Thanks for the reply.
Never a heat issue , Turbo is cooled with coolant from motor ! They make smaller Turbos with sealed bearings but I had this one all set up , didnt want to change it !
I really want to see this thing dialed in. Two strokes are incredibly difficult to get dialed in. The turbo back pressure plays a huge role in getting it to work. If you can size the A/R to maintain a 1:1 pressure ratio boost vs back pressure then the engine functions as if it has no turbo. 4 strokes are easy because you can run back pressure as much as 3x boost. It's very inefficient and the turbo will take a beating but it still makes power. That's why variable geometry turbos work so good on 2 strokes.
2 stroke newbie here, are these two stroke using crankshaft pressure for compression like dirbikes do? Does that mean you can turbo a two stroke dirtbike like this?
@@DIGIT9 Well, from what I've read, dirtbike two strokes compress the intake air using the downstroke of the piston, which forces air through the transfer port and into the combustion chamber. Thanks for your answer!
You gots fueling by electric but where’s your wide band o2 sensor. Carbs are mechanical but your injectors run on wires. A loose connection( and aren’t sleds good for vibrating shit loose) on any one of you plugs could cause pulse width issues. At least you could let off right away under lean conditions or see how black your plugs look under a rich mix.
You NEED an even bigger air box, I think... there is a formula for the size of plenum but it's twice as big as stock... you have a beast and when figured out will be the first sled you jump on daily...lol ..from Wyoming USA 🔫🤠🇺🇸p.s stay safe and healthy everybody GOD BLESS OUR COUNTRY AND stop this foolishness
What kind of crankcase seals do you run in that configuration? This is something I've long wanted to do in a case reed motor. I've finally found a solution with high differential pressure seals. The ones I found are from VR Dichtungen. Brilliant design.
Brent Linderman built this motor , from Arctic Edge Motorsports , ive never had the bottom end apart yet , not sure what he uses but he assured me that this motor can handle 20-25 psi of boost !
@@DIGIT9 Insane machines. Love that kind of build. I've got a budget SRX big bore with Mach Z flatslides and roller secondary. It's an animal but nothing like the insanity you have. I've got a viper chassis that I need to get a tunnel rolled for that I want to turbo.
