Tell Trey to keep those pictures coming...

 

looking good I cant wait to see the bad bitch run!!!!!

you going to bring it here for its maiden voyage ?

 

The hope is that Cliff and I will be chewing up the sand at Dunefest

 

Hey, Didn't I sign up first? Where is my RZR? LOL

 

So what are you guys doing with your old motors?

 

Mine will be for sale, along with the stage 1 turbo kit, clutches, ECU, and other take off parts.

 

Just listen to that engine! :ride:

 

were is yours cliff out back behind the barn? didnt see it

 

Gary's frame is stretching tomorrow, mine is stretching on Thursday.
:ride:

 

Guys, what level of HP you will start with ?:question:
milos

 

Thats a good question, I think Trey said 10psi of boost was around 260hp

 

i have a sawzall lets start cutting.... more pics.... video sound...oh wait they just started......lol

 

Whats a ballpark dollar number for this type of engine/body modification when all is said and done?

 

Each build is custom and will vary depending on what options you want and what you pay for the Yamaha Apex sled.
If $15,000 to $17,000 doesn't chase you away, then contact Trey at MCX for more info. But don't call him for two weeks,,, he is busy!!! LOL
Keep in mind that like other engine swaps you can sell your old engine, ecu, clutches, ignition system, throttle body, intake, exhaust, and misc parts to reduce the final cost.

I was lucky and got a great deal on a sled that already had an MCX turbo kit on it. It was too good to pass up.

 

So this pretty much makes your ride a dune only vehicle or can you trail ride/rock crawl it still?

 

I doubt it would be good for trails/rock crawling..I drove it, It's very pipey and jumpy....but it KICKS ASS in the dunes..

 

Stock Polaris engine weight came in at 101 pounds. We will get the Apex weight soon.

 

Way-
Good Build ....Gary,Cliff..and BigMikeVaderCant wait to see-em doneWhat are your completion dates guys?.....opcorn:

 

For those that haven't seen it, here is a picture I found on the internet of the Apex head.
The Apex is based on the same platform as the R1 street bike engine, but geared to work with a CVT.
998cc four cylinder with 3 intake valves and 2 exhaust valves per cylinder:

 

I am surprised that they are still using the 5 valve head the newer R1's and the new YZ450f use a four valve head because you can tune the combustion camber more

 

It beats what I had before! LOL

 

True

 

This a bit late in replying because I am working on these. But I do think they will be capable of all type of riding when clutched properly. All but water situations. I plan to use my on slow trails and rock climbing.
The one everyone rode in had close to 0 clutch work done. I think it had the wrong weights, wrong rollers, and wrong spring(s). When the clutching is worked on, it will be much more "tame" on the bottom end.

 

Gosh, I must have fallen off the Form, I had no idea that you guys were into this mod, where did you get the engines? Wow, I'm envious but will have to live this through your runs. Pat would disown me for even thinking about this,
John

 

I bought an Apex snowmobile that already had an MCX turbo on it, then crated it up and shipped it to Trey in Colorado:

 

Watching this build can't wait.

 

Mike you need to build one of these also, It would be a blast on the track LOL

 

Apex engine weight came in at 131 pounds as compared to the polaris engine at 101 pounds pics to follow later

 

That isn't bad...
but maybe I should start eating salads and exercising more anyways... LOL

 

The Apex engine weight

 

Polaris engine weight

 

 

A pile of Green Hornet left overs...........LOL

 

pile of leftovers....lol send them my way i like left overs

 

it hard to believe it really fits ... if I wasn't limited 850cc ... I would so be thinking about it!!!

 

Here is a picture of the prototype Trey built. Some things will change, but this shows the general idea of how the engine sits in the RZR:

 

that is bas a$$ Cliff .... I so want one ... just going to have to wait till October, race season ends.
