2-Stroke boosted MOD SLED BUILD TOUR (snowmobile hill climber). Two-stroke turbo.

Ricki gives a detailed tour of his mod sled. The turbo 1200 twin is a Brent Linderman motor on a Ski-Doo Summit X base with a Garrett Turbo. Built by Mountain Magic. Ricki was having a little trouble with the Boondocker box but user error is the culprit. We hate to beg, because it sucks, but KZbin subscription metrics are important.

The new chassis are light years better but a reliable big power two stroke in a new chassis makes a very nimble efficient toy. That’s why you see a resurgence in 500cc dirt bikes.

[@Drunken_Hamster]

If you still have this and are looking into upgrading your turbo, consider Garrett's "new" G series. A G30 should have the same size hot side as this, and you shouldn't need more than a G30-660 given that you're under 500hp. Alternatively, look into Borg Warner EFR equivalents to the G series. Those are even better-designed turbos, particularly in terms of having robust bearing packages. If you really want to eliminate lag, look into a Borg EFR equivalent to the G25-550 or so.

[@StabyMcStabsFace]

This is great advice! I'd also look at the Xona stuff. Same or better spool than the EFR, while being incredible quality. 5451S or 5757S would spool quicker than what you've got, and make more of you need it.

She needs a bigger air box, like a air compressor a small tank means se'll lag from lack of reserve. The pump feeds the tank the tank feeds the engine, small box means the pump is only feeding the engine and can't push the compressed air fast enough and goes straight out the bolw by valve. Same concept in supercharging, intake manifold needs volume.

Man. What a beautiful sled. I am loving your videos. I ride the antique stuff but love the old mods so much I bought one a few years ago. It's a totally custom 2000 Summit built by Brad Oliffe at Powder Assault in Surry BC. It was his personal sled. Has a 1080cc Genesis twin. I've got a small coolant leak from my right side dial-a-dome. Also now my ground wire is getting hot where it bolts to the sled. Any advice? Can you still get o rings and parts for these old PSI engines. It's a sick sled and I want to make it perfect. I'll have to do a walk around video of for my channel.

[@DIGIT9]

Sorry for late reply , some comments get hidden too quick ! You can get o-rings at any commercial bearing place , theres a place in Edmonton that sells Viton o-rings too ! Hot ground wire could mean a couple things , voltage regulator might be on its way out , might have a loose wire somewhere ?

To my best knowledge when you run a turbo on a two-stroke you no longer need an expansion chamber but I guess I'm wrong. And maybe increasing the size of the case will allow you to get more case pressure and the Turbo makes up for the expansion chamber.

[@gallupcustomknives2293]

Wow. And I thought I was crazy trying to turbo my 670 and slapping a 151 track on her...

[@gallupcustomknives2293]

I’m going with a TD03 turbo and a bone stock (non-HO) 670 engine. I’m gonna run stock 44mm carbs (with main size increased) off of a 670 HO, pressurizing the bowls and slides, and using an in-line electric fuel pump and adjustable boost referenced fpr to keep the fuel pressure at 1psi above the boost pressure. (Hopefully haha it’s all theory currently) I’m also gonna install large reed valves in my airbox so off-boost power should be almost identical to stock, reducing lag.

[@michaelhoobler7520]

No reeds my friend rotary valve on the 583 and old 670s I blew my fair share of them up I should no also a non ho tuned rite is stil a rocket on the trails just bring extra gas lol.

[@gallupcustomknives2293]

The reeds I’ll be using are just to allow fresh air to be drawn into the carbs, thru my custom airbox, when not in boost. So not on the engine like in usual configuration on non-rotary valve engine, but allowing the airbox to pull fresh air at low rpm, before the turbo spools up. I was going to run a TD-04 turbo but thought it was too big, so I sold it and got this TD-03 but now I’m afraid it may actually be a little too small for the 670 haha. It may build boost at like 1700rpm

Cat really. Gross.

[@curvs4me]

To get a 2 cycle to work best, you really need a VGT, variable geometry turbo. A Duramax 68mm would work but you will suffer a huge weight penalty. Aerochargers are the only ones designed for the lower egts at the end of the pipes. They run a much lighter turbine housing. If you search around you might be able to find an OEM VGT that will work. For 500hp, it will be extremely difficult to get rid of massive lag. Twins would do it. If you run twin pipes and twin aerocharger 53s you could get 500hp with imperceptible lag. A single 66mm is only going to get you around 350hp.

[@curvs4me]

I really want to see this work. So many people are scared to even attempt it on two strokes. However, VGT is a must, that's why all diesels run VGTs. It's the only way to get up on boost by 1500-1800rpm. They have to do that because they don't rev much past 4500rpm.
