Is the 800xa huge difference in performance on the 600x. I was wondering both on the top end and also out of the hole. I know they are the same chasey but wondering about the engine.

your gonna get a few opinions on this but heres mine. i've had three 800's and if i were to get either the 600 or 800 again, it would be the 600sdi. the sdi's sip oil and get incredible mileage. and imo have damn near the performance of the 800. i've had one complaint since the introduction of the series III 800 and that is its not strong enough for an 800. don't get me wrong, they run great, have great torque and all of mine have been mechanically bulletproof, but a good running 600 sdi will hang right with (or rarely even beat) a 800 all the way through the powerband. i've seen it too many times to think otherwise. so, until they come out with a 150 hp 800 sdi, it would be 600 sdi for me out of the two choices. :div20:

Ive never ridden an 800, but the 600 SDi hauls ass. Unless youre going out on the lakes a lot i think a 600 would be faster than an 800, weight makes a huge difference in trails.

The 800 and 600 are the same weight.

You could either get a 600 HO w/DPM or the 600 SDI in 04.

Personally I can't think of one thing the 600 SDI has on the 800HO other than slightly better mileage, I got anywhere form 12-14 MPG on 04 800. The harder you ride the closer the gap is between the 600 & 800 with regards to mileage.

The thing I like most about the 800 is the torque, the most important factor for trail riding IMO. It's nice being able to get the front end up a bit at 40-50 when you need to.

I ride a 600 sdi and the 800 has longer legs, end of story! Not by as much as an 800n should have but it is undeniable. I have a Cudney clutch kit in mine and I would love to ride an 800 with the same kit. The back shift and acceleration on the trail is fantastic. I love my sdi but my next one will be an 800x, just for the longer legs and no other reason. In the trail the 6 is perfect.

I appologize for all the questions but what is the difference between the ho and sdi.
<div align="right">index.php?act=findpost&pid=919895

one is carbed and the sdi is "semi direct injection". also, no need to apoligize for questions. thats why we're all here :div20:

don't you have to rejet the carbed on depending on the elevation. or is that not true. Then on the sdi they reset themselves automatically.

Both the HO w/DPM and the SDI will adjust the air/fuel ratio based on elevation & temp changes. You'll likely never have to change a thing on either if you stay on the eastern portion of N America, if you go out West and ride in the higher elevations you would have to re jet the carb engine and you would also have to have the computer re mapped on the SDI engine.

Well in the case that the 600 weighs the same, i say it depends on waht you want to spend on gas.

i had an 800X, back in 03, loved the sled, till it caught fire and burned in February of 04, bad time of the year to find a replacement, so i ended up buying an 04 600HO renegade, totally love this sled, and i would say it has the same power as the 800

The 800ho gets better gas mileage than the 600ho too, the 600ho sdi is better than the 8 though.

800 ho has a lot more torque. A properly set up 800 vs a properly set up 600. The 8 will win (in my experience)

For 1-2 less mpg I will keep my 800. Top end they may only be a few mph apart but grab the fun handle at 40 and you can tell the difference. I treid to get my wife on a 600SDI and after 50 miles she wanted off it.

Not if your dealer knows what theyre doing when they set up your 600h.o. Ive been in the situation where an 800 ran out of gas before the 600ho did. Plus the 800ho didnt come in the 03 REVS, the old outdated 800 did.

WHich reminds me, My dad has beaten 03 800s with his 03 600ho. In 03 the 600ho was new and made lots of power, while the 800 was 3 or so years old and lagging in power.

The 03 800 still made in the ball park of 135hp and the 600ho is 115-120hp. With equal set up the 800 should win every time. I know the 600ho revs are quick I used to own one that had some goodies. Did the 03 800 you were talking about that ran out of gas have DPM?

Drop the mains a couple sizes on the 03 800 without DPM and the mileage increases dramatically, it's not as good as the 800 HO's but it's better. I ride with 2 03 800's and a bunch of 600's everything from HO's to SDI's and the 600 is not as fast stock for stock, fairly close up to 60-80 but the 800 is faster.

The 03 800 was way over geared, drop the top gear two teeth and the 600 isn't in the picture any longer until you clutch it. Clutch the 800 and the clutched 600 gets smoked.

I've owned both, and its a no brainer. The 600 sdi may be the best snowmobile Ski Doo has ever made so far. It is the perfect trail and performance sled, while also getting incredible gas milage and low oil consumption. The 800 is a pig in both departments, and is faster only on the top end... and not by very much.
