how many sleds next year with direct injection???

[89sandman]

have read they are ready to direct inject the 800 skidoo, was wondering what was up with the carbs still. guess bp decided not to waste the time/money making an efi setup when they knew they were going di. heard rumors of this happening mid this season. have read they are getting up to 5-600 miles on a quart of mix, SWEET!!! with polaris supposedly having something brand new for 10 and maybe cat too am hoping they come with di. am waiting to buy a new sled for this, think the resell market is gonna drop way off for sleds without it when the time comes. once gas prices start to head back up who wouldn't want a 20+mpg sled, no more carrying gas, unless your going a long way

I sure hope it works as claimed. That will be the telling tale. OMC/bmp sure had alot of trouble with it in their outboards. It will be great for the 2stroles left in this world if they can figure it out. Time will tell this winter.

I doubt you will see the MPH your talking about with DI. Bottom line is it takes a given amount of fuel to make X number of horse. Even as efficant as it is or will be, in the 800 cc class, face it they require fuel.

Its a intresting concept.

On that note I hope the resale value dives maybe I can buy something I could have never afforded before.

Actually the bottom line is on direct injected engines it takes less gas to get the same power because you can run really high compression and lean them out without worrying about detonation. The D.I engine will get better mileage for sure and is the way of the future. The 4 strokes in my opinion are nothing compared the D.I 2 stroke engines and that should be the way of the future not heavy 4 strokes. I hope to see them all out with one soon.

was reading up on it and it does take a lot less fuel for each fire of the plug, pre-atomized fuel burns more efficiantly and thus injects less fuel and you get more of that fuel to burn this creates a much better mpg. being able to adjust the port timing for this, the loss of unburned oil is sooooooooo greatly reduced you may only need a quart for every 5-600 miles. i'm using that for a tank now...

Since the new E-tec engines inject fuel directly into the combustion chamber, why don't they design the motor to use 4 stroke oil in the crank case and eliminate 2 stroke Oil mix? If all 2 stroke oil was eliminated from the burn, I bet they would pass emissions with flying colors! If BRP makes a reliable E-tec motor that doesnt use 2stroke oil in the burn, I would buy one.

The motor still has to pump the air through the crankcase. Figure out a way around that, you've got it made.

 

[hilinerider]

turbo and direct inj. with 4 stroke crankcase would be like a detroitdiesel, and that technology has been around for ever??

 

[Idcatman3]

How do you start one of those? That's the part I've not really understood before. You've got to have exhaust flow before a turbo will do anything, and you've got to have motor rotation before a supercharger will do anything, so how's the system get started?

anyone read about boyasen synchronized charge trapping? what did you make of it?

I would love to ride a BD D8 DFI sled for next year. I would think it would be worth the R&D to perfect it.
