IMO If your buddies have the 800 dragons and they are beating you then your sled has some major problems! I haven't seen a stock 800 dragon beat a stock xc or x-edge 800 in my area. what year is your 800 the V.E.S 800xc is bout 137hp

I know of 7 bone stock studded 800 dragons in my area and they run bout 85-87mph in 1000ft radar runs. When I got my 02' 800 v.e.s bone stock it would run about 87-89mph it was barely faster than the dragons.
Now I jetted mine down to 450's w/ cheater head now i have 157-158 psi comp. .020 off-set flywheel key(which I think you could do without cause you can advance your timing by moving you stator instead) I clutched it, geared it w/ 23/39 ratio 121" X .920" track, studded V-3 reeds. I'm Running a stock pipe and can, and stock air box system wich is diff than yours orig. Now im hitting 95mph in 1000ft run.

I've seen 800 dragon's perform but they where worked on

Check out KRAVEN's sticky on 800 tech tips. He mentioned to use an almound/red primary spring w/ 10-66 weights, R-49 helix Lt- blue secondary spring. I've tried many other clutch kits through SLP and EPI's and i didn't find any setups that worked as well as Kraven's.
Clutching is the biggest part of performance.
My rpm's were around 8,000-8,075 with the 10-66 weights so I ground the weights down to 65grams now I'm around 8200rpm's and I gained alil bit in perform but you don't wanna go more than 8200 then your out of you power band.
But every sled act's different.

In my testing not nearly enuff helix,not even close.Short duration 52* and then straight 34.An 800 can pull more than that.Again thats just my $.02 cdn.not worth much really.

With the pipe and airbox mod keep the stock jetting in it. If you go with SLP recomendations it will not perform, way to fat. Once jetted correctly you should be able to pull 10-68 or 70 weights.

Damn right about that one. SLP recommended after I did their airbox, pipe, and can to go 5 sizes bigger on my main! I doubt the thing would even move if I did that.

My '11 SBA is supposed to run better than the 08-10 Dragons , but it does not have the arm stretching midrange and top end as my piped 02.
Never lined them up though... could be that the 11's smoother power delivery is deceiving.

With SLP pipe + head etc, the sled IMO needs to be really loaded down to put all that torque to work. I don't think Kravens setup would work very good.
My 02 currently run SLP MTX 71+3 weights, EPI red, SLP 50-34 progressive with blue/orange sec spring. right at 8000 all day long.

Jetting: SLP's flatland specs eh, usually err on the fat side. I run stock 500's with a tempa flow. Sea level, non-ethanol fuel.
HP numbers: I've referred to my 02 as having 145+ , not a fan of exaggerated HP claims. Not sure what the head will do for increased HP on top, but it should increase torque across the rpm range.
Weight: Polaris lists the xc800 as 490 dry. I guess that may be a bit optimistic...?
