What did I start?..... I never had a sled with eps nor did I ever ride an apex

That's right. The procross is a very good chassis, it doesn't need to be re-invented, just some refinements. I think it is the best front end in the business, or at least a tie with the also very good Polaris front end.
One thing I'm really enjoying is the lack of constant maintenance that the all Yamaha chassis and suspension was famous for. Don't miss changing bushings, and loose or sloppy steering.

Sometimes reinventing something successful doesn't always pan out. The one 20 something guy on one of the doo trail racer wannabee sleds just spent 4000 dollars to repair the cracked chassis...it was pretty trashed, but not from an accident. He rides hard. I could tell looking back!! LOL.
The cat front end is very impressive, almost stock car like with the way the steel tubing is all tied in.

No I want the 150hp Apex engine in something, I do not want the 998 turbo at 200 plus hp. You are correct though I don't see the Apex motor coming back either and is the reason I don't want to budge off my Apex. Run it till its no more long before I take a 130hp triple.

Now what I see that Yamaha could build is a procross style chassis of their own design without the junk Cat chaincase oil tank setup and the crap driveshaft brake set up. 998 NA making 110 120hp 998 jackshaft supercharged 998 making 150to 160hp and of course their 200plus 998 turbo. 600cc two stroke 130 hp and 800cc 160hp two stroke all in the same chassis.

For that to happen it Yamaha must go it on their own or convince Cat Textron of it. I don't think Cat or Textron would agree, with a all Yamaha engine drivetrain lineup.

Now I know that some will say why supercharge instead of turbo. Reasons are simple, supercharger gives less heat and would not need an intercooler or as large of a one. Its power would be linear and I think more trail freindly with 120 off the line and 140 at cruise speed with 160 on top. It would not spool down like a turbo and coming out of a corner at 30 mile per hour it would be like a viper when on the power winding up to Apex power on top. What can I say it interests me. If I could get the Jackshaft driven super charger for my Apex it would be fantastic. It would be a Yamacharger on steroids!

I agree, a supercharger (blower or mechanical turbo) would be a better power fit then a traditional exhaust driven turbo. Yes a supercharger has some parasitic power draw, but the power is instant and more linear then turbo. Reliability is not a issue either, I mean look what a supercharger has done for Mercury's Verado outboard. The only time you get into trouble with blowers, is if foreign objects get introduced, which shouldn't be a problem with our machines. While I still believe in the adage that "there is no replacement for displacement", if you are going to build power with some form of boost, then a supercharger would be a better solution. Okay before I get crapped on, yes turbos are used extensively in the auto industry and is all the rage now, that is that way because they are using such small displacement engines to start with, they cannot afford to sacrifice the the power to drive the supercharger, plus the instant power surge is not something required in the consumer auto. Why do drag cars use blowers and not turbos?

Yamaha has done such an incredible job with the individual throttle bodies on the Winder, so much so that I would take it any day over a supercharged sled.
I speak from experience and many trails miles on both the Winder, and formerly a supercharged Nytro. I never would have thought a Turbo could produce such instantaneous throttle response. The supercharger also turned my Nytro into a gas guzzler.
Turbos rule!

Drive my tuned sidewinder and you will think differently. If I put the stock muffler on it and the stock intake, you would never know it has a turbo, and it can still make 270hp with a flash. The power is as smooth and linear as you could ever hope for. There are no situations where there is turbo lag with the stock sized turbo. Fuel mileage is a major issue with supercharged engines. I have a turbo Honda Aquatrax, it uses 1/3 less fuel than a supercharged 215 seadoo, and 1/2 the fuel that a Kawasaki 310x uses. no

Great post. There is a reason why car and truck manufacturers have all but abandoned SC's and embraced turbos.
 
And why are all drag racers and rally and time attack motors turbocharged an not supercharged. They are leaving blowers and nitrous in the past

Because in that case you cant afford turbo lag. Even if its a split second, that split second counts when you can go 300 mph. If time doesn't matter then a turbo is where its at. For example is tractor pulls. They need to move a large amount of weight with no time to worry about so they can afford to wait for the turbos to spool up before they let the clutch out.
 
One and done on the Snow X effort, all the power in the world don't do you any good when ya can't get anyone to stay on because your suspension isn't up to par with everyone else's. Robbie was an animal back in the day and he couldn't stay on that Nytro to save his a$$.

Because turbos were banned.

Its not beause its the last. It was an awesome motor. It has great response. Great top end. Sounds great. Reliable. And smooth because more cylinders are always smoother running.
Back in 97 i was told they would never get rid of the 800 4 cylinder. Best motor out there and they will stuff it in the sx chassis. Then 98 brought the srx. Faster and better handling than the 4 would have been. Not as smooth. Not as good sounding and not as reliable. But it brought a lot people to yami than the 4. I believe thats where we could be if yami released a new chassis.

And then the twins took over even less smooth, less reliable but cheaper to build. I think its all about the cheap.
