It would need a reverse box. Im not sure the sleds have reverse maybe they do check it out if it has reverse then we need to find one. Rick the 1000 prowler can be turboed and make that kinda power.

For the money i think you are right Todd, about doing a turbo on my XTZ 1000. i have been talking with Chris for ideas. I think I will try to turbo my cat this summer. Any tips or suggestions would be what i need. Maybe I could order this turbo form Arctic Cat and it would just bolt right up:D

Hey Rick I would say that you should talk Chris on doing the Turbo he has a fuel system for the turbo that make it so simple and easy to dial in it is ridiculous. I wouldnt talk to anyone else about it. period.

Mountain Performance just announced a supercharger kit for the xtz. They claim 112 rwhp on only 6 psi and running on pump fuel. That is incredible.

Look on prowlerforums.net MPI left a post there about it with some information. They are supposedly just doing a little more testing this week and then are going to put it into production.

i dont know about you guys but these xtz's run pretty hot. You would have to find a way to increase the cooling capacity and intercooling would be necessary to run a turbo on these. Stick your hand down on the plastic engine cover after 30mins of riding. John (UTVGuide) said it in his article that the cooling didnt look that great on the pre production one and i am not sure they addressed that on these. There are tons of engines you can stick a turbo on and not have to modify if you arent running 12+ lbs of boost but i dont think this is one of those engines... I see bigger radiators, oil coolers, and intercooler if you want to keep your engine more then a few rides. Vtwins are inherently hot by design because of the uneven cooling not like a inline 4. Maybe some NACA ducts would help, i havent looked under mine yet to see how the motor is cooled. Would be bad arse for sure tho...youre a braver man then me, i havent had mine over 55-60mph yet!

Course i am waiting on decent shocks, tires and doors... :)

There is a duct that runs from under the hood past your cup holders to the engine compartment. We could probably modify the duct to be more effective that's for sure. The fan used on these is a 12V Spal VA11-AP7/C-57A, which is only a 1350 cfm 10" fan with no shroud. There website shows a VA10-AP50/C-61A fan that is about 12.5" and gives 2270 cfm at 12.4 amps. I am looking into this as a direct bolt in replacement if they do a shroud with it. I will call Spal tomorrow.

has anyone removed the tow plate in front of the radiator yet? I thought about it, not sure my grinder would do much, its a pretty thick plate.

Ok here is what I have found...

I spoke to Spal today as well as Brian at Custom Aluminum Radiators in Kingman. Spal recommends them for radiators, fans, and shrouds. Spal does not sell shrouds because there are so many fans and size variations it wouldn't be cost effective so they give that to the radiator shops.

Brian from Custom Aluminum Radiators gave me an education on cooling systems and how it all works together in harmony. As far as the shroud goes he doesn't think we need one on this type of fan. I am just telling you what I have been told. I am not saying this is accurate info. Call and discuss this with these guys if you would like. The plastic case that surrounds the fan is sufficient. It has to do with the recycling of air off of the tips of the fan blade and the venturi affect to suck air through the radiator. In some cases the where the fan blades stick out past the plastic housing you would need a shroud. I don’t know if we have a cooling problem with the XTZ 1000 because mine has been good so far. I have not seen ambient temperatures above 90 degrees yet though so time will tell. I know there are a few guys having issues but it seems to be linked to improper head torque or air in the system. Once those two are fixed it has not been a problem as far as I can tell. If someone has the ability to check the return water temperature on their XTZ 1000 and post some numbers that would be a big help in determining if there is a potential overheat problem. Mine is in the shop for the axle issues so I can’t perform any checks. Also shoot the radiator core with a temp gun and make a note of that as well. The radiator seems to be very large compared the 650 and 700 so I have to think the overheat issue is limited. There is a larger fan from Spal that looks as though it would fit in place of the stock one. The stock one is listed on Spal’s site as VA11-AP7/C – 57 A it has a current input max of 9.5 amps and pulls a max 1350 cfm. The one I was looking at as a replacement is Spal VA10-AP50/C – 61 A which has a current input max of 13.6 amps and a max cfm of 2270. I think the XTZ is good for 25 amps max? With lights on and fan at full speed I don’t know if it can handle it. Someone chime in if they can run the numbers and figure this out.

You can't tell from this picture but there is a gap between the fan and the radiator.
