Comparing the the two sleds isn't really possible.

Most reliable: Pro
Cheapest: 800
Most power: Turbo 700
Most expensive: Turbo 700
Most expensive to run: Turbo 700

Assuming you would sell the 700 to pay for the Pro or the 800 Dragon

It could be debated that the Pro would cost more, but with that you get a solid chassis that is much lighter with a warranty.

If I bought a Pro I wouldn't touch much, maybe the shock with either a re-valve or different shocks.
 
OMG My sled ran flawless today.....

No deto today with the warmer temps... pulled 8300 RPM all day, Auto Tune's doing it's thing... life was good today w/ "the Fix".

Harry,

Before your engine failure, did you happen to notice a very slight reduction in RPM's at full pull prior to the implosion?

Great to hear your sleds running great!!

I know you were asking harry but i thought i would give you some info on mine before it went down, It would not rev out as high as it used to with the same setup, used to pull 8300 all day but would barely pull 8000 at the end, it would idle very low 1750rpm and would have to try 4-5 times to get it to go in reverse, i could tell it was on its way out it just wasn't the same sled. It just kept loosing power till it went into limp mode. hope that helps,

My friends 800 that imploded was not pulling quite full rpms and would pull down to 7700 rpms on a good hole or hump and have a hard time recovering. It was like the secondary was sticking. Ironically, SLP told him when they have a 800 dragon not holding r's, it is most likely on need of piston replacement. 3 rides after that call and not holding r's......BOOM! And I do mean BOOM!

The moral of the story.....lift kit. That what we are calling the fix.

Got a lift kit?

I like lift kit!!!! That's a great name for it.

My sled before failure, climbing a small hill, sled was pulling 8300, then it skipped for a milisecond, and pulled 3 more seconds til I summited the hill. It then IDLED HIGH!!!! it was totally weird. I thought something might be wrong, but I kept riding it. After 10 more minutes of riding I noticed 8000 rpm was the max.

I headed back to the truck. About a 16 miles trail ride. When I got to the parking lot, it was struggling to move under it's own power.
My buddies had to pull the skis to get it loaded in the trailer.

I had to drag it out of the trailer upon arrival to TCP.

Any other questions??
 
How is the fix working guys??? still running strong???/ Did anyone pull there exhaust valves and look in to see what the pistons look like???? Thanks for any updates.:face-icon-small-hap

Engine cooling mods?

Harry,

Are you runnning a stock T-stat/ T-stat w/mods or the Gizmo? Curious if you have done any cooling mods to help the motor run cooler?

Appreciate the helpful posts.

Thank you,

No thermostat mods and no gizmo.

Another great reason to subscribe to dynotech is ....... Jim ran the D8 on the dyno with and with out thermostats. Sled ran much better around 100 degrees according to DtR.

My sled is running 120-130 degrees.

I make sure my water temp is 120 before I go wot for a substantial amount of time.

I always let warm up to 110 before we leAve the lot and take it easy for 1 or 2 miles on the trail.

Heat cycling an warming it up is crucial.
 
Does anyone know the exact thickness of the spacer plate?
I'm curious on how much they raised the cylinders.

Glad to hear this solution is working so well. So what is the conclusion on the boosted D8's? Is the fix recommended for turbos? Thanks
