ALSO THE EFI SYSTEM DOES NOT NEED "AIR" TO ADJUST, IT ADJUST THE FUEL CURVE TO THE AMOUNT OF AIR GOING IN THE ENGINE READ BY A SENSOR.

no it doesnt but i does need "air" to combust fuel. and you said

thats not true. It wont need to be rejetted but it still will make it less efficent. EFI will "rejet" or ajust fuel output to prevent a rich or lean mixture but the engine still wont be as efficent as it would be at a lower elivation. so what you said was totally wrong thats what I was commenting on. I agree that 44 miles per hour is most likely a combination of factors one of which may be improper jetting but even if that is fixed at that altitude it still will have less power then if it was brought to sealevel and rejetted.

 

I am ok with that can we also agree at that elevation a properly tuned engine may not make as much power but will still be within a couple of mph?

 

ulgy88 did you knowtice a difference in power and how loud is it?

 

I noticed a little bit, but I do not have it completely fine tuned yet. I have to do a complete rejet on it since I added the intake and UNI filter. I am just trying to figure out which jet kit to use. Not much louder.

 

yea i can agree that 44 seems slower then just elivation.

to what baller has been saying about the megamax, you said you didnt notice much of a difference? How many disks are you running and do you have the quiet core in? I ran mine with 10 or 11 disks with my K&N filter and a few holes in the airbox lid. I run it with 10 disks now but I have a white brothers cam and a high compression wiseco piston. the cam really makes a difference in the RPMs it winds out so much smoother and longer.

 

No, no, another misunderstanding. I did not see a lot of difference from using my stock exhaust slightly modified. I did see a little and every bit helps, I also wrapped the entire header pipe and tail pipe up to the muffler with header wrap. I want to get a White Bros. or Mega Max II but can not justify the cost right now.

 

Go with the MegaMax I got a MegaMax on my Wolverine and it makes it have alot more power you feel the difference soon as you ride.

 

Wow I leave for a week to go deer hunting and this topic just takes off, I still need to chime in on this one with my opinion. I run bigger tires and I think they help me in the top end, so I think I am closer to 60. Either that or when I raced my dad on his sportman 500 HO and his speedo said 59 and I was slightly pulling away his speedometer must have been off by 15 mph. [img]i/expressions/face-icon-small-happy.gif[/img] Ahh now I see the problem, Damn Polaris speedometers.

 

I am wondering what are the biggest tires I can put on my wolverine with the stock rims. I see that on the back stock rims you can put 28's on them 28-10-12 and the biggest tires on the front I saw are 25-8-12 and I am wondering if I can go bigger on thefront if I dont change my rims. If i put 28s on the stock rims will i need a big foot kit or anything??

 

I would not reccomend outting any tire on your Wolverine bigger than a 25". You can do it but you will loose a lot of bottom end torque which makes it tougher on the machine to get through sand and mud. Also, you must put on the same size on the front and back since it is constant 4-wheel drive. When I say same size I mean in diameter not width. I put 25x8X12 on the front while running 25x10x12 in the rear.
