Doo 600 vs Cat 600

Anyone have both of these in a group? Just wondering how they compare for real world power, gas/oil usage. My guess is they're comparable when ridden about the same but interested to hear from people who have actually ridden them both for a decent amount of miles. Seems like both will last a long time, engines at least.

Close friend of mine his son has a 600 A/C Ctec-2, and another guy in their group has a 600 Etec Doo. The cat gets worse MPG's the harder you push it, not so much the Etec. He says oil use like wise. The Cat uses a lot more oil the harder you push it. Etec 4 plus MPG. Performance very close between them. They are cat guys to the max, but he said is considering a Doo on dealership reasons. Biggest complaint I have heard is the 600 Ctec-2 doesn't get the MPG's that was expected, but it is a semi-direct injection, Etec is direct injection. My SDI 600 Doos are 3 to 4 MPG's less than the Etecs also. Both seem to be very good IMO. My SDI 600 Doos have gave me excellent performance for very many miles untouched.

Only experience was riding with one for about 350 miles. Cat got 13.7 mpg on the same ride my Poo 800 HO was at 14.9. Fairly hard packed trail cond. at a good pace.
I'm sure it loses the mpg battle to the Doo etec everytime ....if that's a big concern.

snowbuilder, it seems the "new" design Poo 800s get better MPGs than the old ones. Do find the same results???

Almost 40% of any sleds mpg is the engagement number on clutch and the looseness of the track not the manu....the best way to increase any sleds mpg is to loosen the track till it ratchets....then tighten it a skotch....the cats mpg will now be better than the doos....a cats clutch engagement is higher than a doos from the factory....a doos track is longer than a cats so that's more mpg....same as larger tire...clutch still spins at 5000 but track travels more distance on a doo....lug heights are smaller on doos...this is comparing the 2 you stated of course or any 2 alike...if anyone is thinking about increasing mpg by loosening the track....don't if u have studs....another reason they suk....my vote....cat hoosier....cause it's tougher and can be dialed in to match the mpgs or best the doo

Several things at work here. In general a 600 of any make is going to have to work a little harder than an 800 to maintain a speed of say about 70. Generally it will achieve that by revving higher. If your average 800 is spinning at 5500 to 6500 cruising at 70 you can ad about 1000rpm for a 600 to maintain the same speed. You could in theory 'clutch for mileage' if you were going to ride at 70 all day every day but then other aspects of the sled would be altered unfavorably. If the Cat does in fact engage higher than the 'Doo it is also probably carrying that extra rpm all the way up. There is your mileage difference. Tracker is correct in that reducing drag any way possible will help mileage. Also the higher the lug height the more power it will take to turn everything. Also are they both geared the same? Motors themselves are not the sole factor of mileage.

I know there are a lot of factors - that's why I was interested in how they did riding under similar conditions and speeds. Bud got a new Cat 600 this year but we just had it one trip with about 700 miles so hard to tell yet.

I rode a Doo 900 quite a bit last weekend and I was surprised how much I liked the chassis. I don't think the engine had quite enough for what I'm looking for but I didn't have the conditions to really try it out either. I figured it would be great with the 600. The only thing I didn't like about it was it seemed the seat should stretch back a bit further. On the Cat there's more room to move back and forward.

Hoosier - I looked hard at the 900 ACE, and my conclusion was the Cudney clutch kit was needed to get the RPM's, and performance I wanted. You kill the MPG a bit when you do that, but then for the extra $$'s, figured best to just stick with the 600 2S for same cost. I couldn't decide for months.

If you ride your AC 600 3000 miles you will burn 218.98 gallons of gas at 13.7 mpg. If you ride a new 'Doo and get 16 MPG you will burn 187.5 gallons. That is 31.4 gallons less in 3000 miles. At $3 bucks a gallon that is $93.00. If that is a determining factor in your sled purchase ........ ???????? Much more important is your dealer. Also how the sled fits you and what you like to do. They are all good at this point.

I owned the '14 El Tigre CTEC and currently own a '16 Renegade 600 Etec. Put about 1500 on the El Tigre and about 1700 on the Renegade so far. I've found the Renegade 600Etec just to be alot more comfortable of a sled ( 6'1" 280 lbs) for me. The suspension on the El Tigre was harsh no matter what I did it seemed. I bottom the Renegade a fair bit, but can dial it into being very comfortable 99 pct. of the time and still bang through the whoops pretty well. I never bottomed the El Tigre CTEC, but it beat me up pretty good over just about any sort of bumps, which is why I traded it in.

Gas/Oil definitely goes to the Etec, I average 17 on the Etec (got 19 this past weekend trying to snake my way around the mud by Presque Isle). I never got above 14 on the El Tigre.

Power wise, they feel about the same to me.

I'm not brand loyal at all anymore, I can say without reservation that the Skidoo has been the best all around sled I've ever owned ( '02-'04 Vipers, "77 Exciter, '09 Apex LTX, '05 Rage, '14 El Tigre, '11 TZ1, '14 Indy 600 ES).

Oh gawd, don't let the resident Yam dealer see this, he'll have an aneurysm when we start talking 46% market share again.

I will say if I rode mostly RR grades, the 4 strokes would probably be my sled again. I ride everything from Illinois cornfields to the SW UP and the Renegade does the trick for me. Might try a Poo SB once the Gade is done, but no plans to part with it anytime soon.

Thinking more about range than price but good example - makes you realize how little difference it makes in dollars.

Both are great sleds, you really can't go wrong with either one. Go with the one that fits you better ergonomically. The mpg difference between the two sleds is very marginal, so don't let that be your determining factor. Being comfortable on a sled greatly increases the fun factor, especially after a long day on the trail. Good luck and enjoy whatever you purchase!!!

Here's another thing fellas...just like the wind sails on semi trucks these days.....you put on a taller windshield and it increases MPH and MPG at same time....those numbers posted in the beginning of mpg could be due also to front end erogos and size of windshield....small is not fast....mc fly wind screen makes Ricky slower....lol
