Installed SLP Pipe, Can, Head 3-6,000 Alt.

[PJ-Hunter]

I have the SLP y-pipe, pipe, head and HPS can (didn't put the SLP can on) on my 08 800 XP and it screams! Actually it over revs a tad. I ride at 10,000' and I left the jetting the same to start with.

I had the deto sensor and check engine light come on last year and it didn't come off. Turned out that the deto sensor AND DPM module had gone bad. Take it to thew dealer and have them check it out. It's under warranty so it'll not cost ya.

I know what you're saying TJ....but a lot of guys are throwing this SLP stuff on, wondering why it seems sluggish, then taking 2g (or more) out of the pins, then claiming, "wow, it really pulls now".....even though they're pulling the same RPM as before.....

I agree with that. If you leave the same ramps, helix, and have to take away weight or go to a stiffer spring you just went backwards. I would really have to see ANY ski-doo pipe or pipes in action side by side before I bought one.

we had 3 08's last year----2 stock and 1 with y pipe and head----drag racing they were all close---on the hill in good snow the sled with head absolutely killed the 2 stock sleds----clutching was same in all 3

That makes no sense. The one with the Y pipe and head should have more HP(according to the claims) so clutching would be different to utalize the power. So if cluthing was the same in all three sleds and the one with the pipe, head was outrunning the stockes sounds liek you had a bad setup in the stockers. How can you have a sled with more power and run the same clutching as the stockers??

it would take $2500.00 to do the testing on various clutch set ups--everybody has different ideas and way to get to the same end results so we opt for a good running sled and save the cash---we also trade about every year and it makes no sense to doo all the testing---did 5 different set ups from DJ last year and found NONE were better all around than the stock--big waste of time and effort

Makes perfect sense actually....the head gives higher compression. Top RPM is the same...peak HP is only increased marginally....but MIDRANGE PULL is increased huge with added compression....from any head, not just an SLP head.

Edit: everyone with an R motor who rides over 6000' should raise the compression. Stock is 12.75:1. Dyno testing a bunch of different heads also shows us that the HP (midrange) increases are the same for a cut and reshaped head VS. any aftermarket head out there. You will gain some efficiency with an aftermarket head, but no more HP. Want to wake up your R motor and make your clutching woes go away? Get 'er up to 13.5:1 and run good fuel.
