Gents...I need your help please
I have a 2008 Polaris IQ Factory Racer...I am putting on the 800 Top End and Pipe Mod from Bikeman Performance (very nice guys to deal with)
Anyway I would like to put oil injection on it if possible.
I purchased an oil pump from a 2008 Polaris 800 CFI Engine...The oil pump has 6 outlets.
The IQ Racer bottom end has 4 check valves on the crank case (one lubes PTO Rod Bearing, One lubes center bearing, One lubes MAG Rod Bearing and one lubes the MAG crank bearing)...Also there are two fittings on the carbs.
So as you can see I have six outlets for six outlets but unfortunatkey it does not appear to be that easy.
The 600 IQ Racer has the "grease zerK" for the PTO bearing and the diagram for the oil routing (for the 800 CFI engine) shows two of the outlets that come off of the oil pump "T'd" back into one and then into the PTO side of the crank case near were the fuel injector goes in.
I could not find any specs for oil pump output so I conducted my own "somewhat" scientfic experiment by cutting some oil line in equal lengths and marking a scale on each line...I then used a drill to measure oil pump output....2 of the lines appear to put out approximtaley 3 to 4 times as much as the other 4. (This would be the outlet that is in the middle of the "top 3" outlets and the outlet that is in the middle of the "bottom 3" outlets)
So my questions are these:
-Is it possible to have oil injection with this set up and still have it give the engine adequate lubrication and protection??
-If it is posisble can someone please offer some of their expertise on how to route the oil lines???
Thanks to all for your help.

You will need to pick a total of 4 lines coming off the pump and use these to lubricate the motor.. You may have to do some more experimenting with your drill and some more oil. You have already figured out the 2 lines that pump the most oil (lets call those the Primary Oil Lines), now plug 2 of the remaining 4 and see if the pump acts fifferently (ie, more oil is pumped out any of the remaining lines like the primary? or the other 2? I know it will be a PITA but you need to make sure you Primary Oil Lines still pump the most oil even when other ports are plugged off.
I would say the Primary Oil Lines and should be hooked up to each of the Carbs, this will allow fuel to mix with the oil and travel through the complete cycle lubricating everything except the bearings. Now hook the other two lines up to the Center Bearing and the Mag Bearing, the PTO Grease Zerk will remain like it is, no oil going to it.
Many of us have been beating this around all winter and no one came up with the perfect answer as to which lines go where. You having a pump and being able to do a little experimenting may be just the answer we all were looking for.
Hopefully one of the other guys who discussed this idea will chime in.
Keep us posted.

Thank You Tom
It appears that when you plug 2 of the 4 "non primary" oil lines the ones that we thought were the "primary oil lines" continue to be the ones generating the most oil output.
Basically everything stays the same no matter what you plug or how you plug it.
As I am sure you remember from our discussion one of the biggest points of confusion was that on the oil routing diagram for the 800 CFI they have a primary and secondary oil line "T'd" together and then goign to the PTO injector area (similar to the "carb area")...Is it possible since this particular engine (the 800 CFI) has 5 check valves (3 on engine, 2 on carbs) that they (Polaris) couldn't use/didn't want to use a "4 output" oil pump so they used a "6 output" oil pump and simply needed a place for one of the extra secondary oil feeds to go???
If my thought process above seems logical then we may have our answer... Take the primary oil output lines and connect one to each carb and then the 4 remainign secondary oil lines would simply go to the 4 check valves on the case????
If anyone could chime in here it would be greatly appreciated.

Hello Gents
I just wanted to "re post" this topic as I was hoping to get more input and feedback.
I think I have it figured out but what just like some additonal thoughts and input if possible.
Thank you all for your help

I looked at a cut away engine at the spring show and wrote down how they had it on that engine. My plan was to make the 6 outlet pump a 4 outlet pump by using 2 T's. I was going to feed the 2 checkvalves that dump into each crankcase with these doubled up lines. The other lines would feed the bearings. I did not want to pump into the carbs.
Also, the crankcase has to be split to make the 800 cyl. fit on. I was going to look into changing the PTO end to what the 800 has so I could add a checkvalve and dump the grease zerk. It may end up being more work than its worth.

One other thing, no matter where the oil goes, it all ends up in the crankcase at the end and is burned. Other than the center bearing, the cranks we have live fine on premix with no dedicated oil going to any bearing.

I looked at the diagram I made of the 800 engine at the Lake Geneva show, the center output from both the top & bottom row went to each cyl. The others were routed to bearings.

Thanks Never, this should help. I am hoping to do at least one of these oil injection installs on an '08 600 motor this fall. We'll keep you guys posted.
