I want to post about my experience with the Speedwerx Procharger for a 850 Polaris and so others can communicate the issues or tuning recommendations and helpful experience with them..
Install is pretty straightforward but you have to be a Experienced Mechanic to do the install .
Install is easy but the tools needed are not in common boxes. And this is a very meticulous install, most hardware is only accessable by fingers. A set of ball end Allen Wrenches is a very good idea.
Very Very Important things to know during install ..
The Supercharger Drive belt goes around the large lug on tbe Drive Adapter that is over the flywheel . If you miss this you have to reinstall the entire kit !! READ THIS AGAIN!
Bolt the tensioner on before installing the drive adapter !!
Can be done after but VERY tight .
The "Recoil Bushing" is in the bag with the silencer rubber bushings. Might not be in some kits but mine was.
Rubber Washer goes under the coolant cap. This is Not stated in original instructions.
The Intake housing comes off very easily and needs to point at the steering post . There are two holes on the intake housing that will need 5/16 plugs with locktight. This can be fixed after install easily, just take all cap screws out and remove housing. ( Charge tube. Intake tube and Silencer removed also) The Threaded Holes are open to the boost so must be plugged. One is on the top front position and another pointed at the top RH a arm .
If you install the recoil as described in the instructions it is very hard to get at the Drive Adapter mounting Bolts.( Have to rotate recoil cover to access each Drive Adapter mounting bolt)
A way easier way is you can remove the two rear motor mounts and RH front ( two torx bolts on belly by R FR suspension mount) and lift the engine far enough to install everything easily ( If I do another I would start with this as a pre install step. It would save 4-5 hours)
I would also include leave the Bottle to Pump hose removed till the end before the brace install and after drive belt adjustment.
Recoil spring rewind is done easily with two screws in a board and a straight edge to keep the coil all flat while tightening. ( OMG What A PITA)
Mount the AUX injector controller low. The headlights will hit it if mounted to high.
The silencer Brace is a aluminum bar ( not shown in instructions) With four large holes milled in it. Instructions describe installing silencer to it with supplied Bushings/Pins and bolting to chassis last .Easier to just Bolt the brace on and install the silencer pins after careful silencer install .
2.5 ounces of oil fill, but 10 ounces are included .. 500 miles or each season change recommended.
Intake Elbow is very tight to, if not hitting side panel. I trimmed the 90 at the intake housing to get it as tight as possible but a flatter transition would help ( going to experiment with heat and some trimming on the panel if possible but I think it might "WEAR IN" .. going to try a Duramax LBZ Intake Elbow or similar.
Overall I'm impressed with the workmanship and fit.
Will report back on how it works after ECM is returned.
