I just bought a 2005 MXZ 600H.O. SDI Renegade with 4000 miles on it and its in perfect condition. I was curious to know the top speed of this sled and how well it handles and other information regarding it that the website wont give you.

I am also intrested in getting upgraded headlights,exhaust and what oil is the best to run in it?

I would appreciate your help and your information will help me before the snow falls.

I've been running amsoil interceptor in mine since new with excellent results.

The top speed will be about 95mph indicated, but with the big track its probably closer to 90. If you're looking to be the first rider to the end of the lake, you bought the wrong sled. It'll do 90mph all day long every day, but that's about it.

Handling is as good as anything else on the market, the 136 skid tends to soak up some of the stuff the 121's fall into. Bottom line. The sled is more capably that 99% of the population.

As for the pipe. DO NOT touch the stocker, leave it alone, noise does not equal power. you'd be better off spending the money on clutching you'll gain more "SEAT OF THE PANTS" power and you won't be closing trails because of a loud pipe

Also leave the headlights alone, the sled has limited power capabilities as it must run the fuel injection system, if you start adding higher wattage bulbs etc, you'll run into electrical load problems.

The stock lights are more than bright enough for any safe speeds you can do at night and you won't be blinding oncoming riders with them.

I've run Amsoil in the past and it worked great. No problems what so ever. Last year aI tried Torco and found it decent but my exaust valves needed more cleaning than they did with the Amsoil.
As for a pipe. Really at this point in time don't bother. Clutch it first and formost. Personally I would hook up with Dynamo Joe at http://www.mxzx-revzone.com/ or Bill Cudney over at http://www.cudneyracing.com/
Bill also has some really nice heads that work well. You wont gain a whole bunch of power with his heads but the sled will be way more consistant when you run it hard.
As for the trop speed. Like dpaige has mentioned it's not a lake racer. I've hit 103-105 on GPS with my short track MX Z so I would knock about 5 mph off of that with the long track.

dp may as well have written my reply. I agree 100% with what he said. Although I have got 98mph on gps once, but that was ideal conditions, not on a regular basis.

98 is definitely possible.

I'm running a 2in track and slightly shorter gearing, I'm sure with a 1.25 my would do 98 if I rung its neck but I tend not to run anything wide open for that long.

I couldn't care a less about being the first to the other end of the lake.

I've hit 104 mph on a hardpacked, groomed racetrack, 136 inch 1.25" track. The other guys said 98 was top speed, but I did do it. That was looking at the speedometer, hard to do, but on a perfect groomed track you can. Wish the numbers were bigger on the speedomoeter, so it'd be much easier to see.

Handling - If it has precision skis it will be quite darty on hard snow. People have said Pilot skis make a big difference, but I can't say because I don't have them.

I did run the regular ski-doo (Castrol) oil but now use Amsoil. Supposed to be better, don't know that yet either, but I do know that it smells a lot better than Castrol.

As for adding all sorts of things, not really into that, like it the way it came from the factory.

I've had numbers that high on the speedo also, but its not accurate. I was using GPS speed, and never get as high as the speedo says.

The dream meter or speedo is not very accurate. You would be surprised at how high I have had my speedo showing

Just make sure that you don't use regular mineral oil. It requires at least the synthetic blend.

I see what you mean there in your picture, but I've never seen my speedometer do that, and the needle was the same as the digital readout with mine. Could be wrong though I guess, seemed to be clipping along pretty good at the time though.

You just may have been doing that speed according to the speedo. Not going to argue that. I've just never found them to be that accurate. Not sure why they have so much problems with it. Every Fire Cat I ever tested had a speedo accuracy of about + or - 1 mph. Heck if Cat can do it what the heck is up with BRP.

the speedo will say lots of different things, it doesnt mean you're actually doing that speed.

you've got a bunch of different factors working against you trying to make this particular sled, and all of them have a to do with basic physics.

being an 05, you've got the 16in track which carries more weight than a 15in. I've run several different tracks on my 04, and had to make clutching changes to compensate.

these sleds are making 118-120hp.

with the large frontal area they have, they're about as aerodynamic as a brick as well

At 100mph, gaining 1mph in terminal speed requires about 3 additional hp. even in ideal traction conditions it is actually easier for the motor to spin the track than it is to continue accelerating the sled.

you'd think that track spin at 100mph wouldn't really be a factor but it usually is.

I've experienced this sort of thing first hand on my racebikes. At one particular track I was dealing with what I thought was clutch slippage at high RPM in upper gears and my mechanic changed the entire clutch assembly 3 times over the weekend, we eventually found out that the setup we were using to make the bike turn was actually causing wheel spin at 150+mph while the bike was going in a straight line.

the bike still had power, but it didn't have the traction to continue accerating. In this case, the path of least resistance was to spin the tire rather than moving forward.

we figured the problem out, made changes to stop it and I promptly destroyed the bike in qualifying because I was carrying an extra 10mph into that corner than I was accustomed.

Everybody ... Donovan. Donovan .... everybody.

Good, the formal introductions are finally over. :D

LOL...glad to see you survived.

Yeah, I come from a long line of specialists in this area.

The wee fella on the right is yours truly.

BWAHAHAHAHAHA!!!

Thanks DP .... another dead keyboard!

Ha ha good stuff. Good stuff in the post above too. I'll try it with the GPS this winter if I get a good track, (that usually means a good flat pond in our area), see what I get.
