Does any1 have stock HP from dyno ?

It makes 150 @7900 on our dyno

That must be the CAT dyno. Other dyno no's i have seen on the net was 155-7

Hahahahaha screw the dyno.......the real proof will be passing F1000 CATS!!!

I don't think that'll be a problem unless they are tuned and have a couple grand into tuning them. Stock for stock, I think the XP 800 will walk away from the F1000 in a drag. It'll leave the F1000 way behind in the twisties and rough stuff for sure. Only time will tell though. A lot of guys have already modded, or tuned their 1000's, even before the snow started flying.

We have also shown 150 hp at 7900 on our dyno. With some timing and rejetting you can pick up some easy hp that is left on the table.

143 out of the box no mods. Its a correct number as another facility pulled the same number with the sled they had. there is power to be had with some tuning. We have dyno sheets on our site.

I saw something over on dootalk where hey dynoed the sleds and it put 108 to the ground. The 1000 cats were like 113 i think.

I'm in no way trying to start anything, so with that said I saw that on the the AC forums some ppl have dynoed the 08 F1000's and they were hitting around 169 - 171 (stock) and some guys took them out of the crates changed the track and shit and took them on the pavement and the two that I read hit 121 and 124 mph. Cat has done some work to the F1000 this year because last year they were not performing up to par and were dynoeing aroung 162-165. However, the new XP 800R should be super fast as well if its getting around 150-155 hp. I also hear that the new Dragon 800 is going to be really fast as well. I guess only time will tell.

Bring on winter!!!

what does 108 to the ground mean???

you are so wrong about the twisties comment its silly...you boys are in for a big shock...cmon snow!!!! its ass spankin time...

Ya, you'll get your when it's time. Don't worry.

Track HP, meaning it was a track dyno and not measured at the crank. IE real world HP, 200hp at the crank with crap clutching means squat.

108 at the track is impressive for a 800.

So how much coin have you spent so you can talk shit about beating stock 800's? The stock F1000 is not much to right home about, we all know that.

Add 3K in mods and a big shot of NO2 to the XP and you might be in for a shocker. You don't hear any of us calling out any F8's do you? Just wouldn't be fun or fair for that matter, nor should it be.

I bet you will see some changes next year for the F8. When you think about it, the XP has 155 area HP, and the new poo 8 will have the same area. Now looking at cats F8 which sits somewhere around 143 stock? I think for 09 cat will have some more power out of their 800 to stay competitive. All 3 brands need to shed weight and play catch up to Doo.

I don't want to turn this into a Cat/Doo pissing match. The F Series sleds are really nice, just didn't perform all that well out of the box last year.

Just pointing out that it is ridiculous to compare a heavily modded 1000 to a stock 800 is all.

I wasn't trying to turn it into a pissing match. I was just commenting on how it will be some great compitition for us next year. Doo keep's raising the bar leaving others to play catch up. I'm not at all a Doo guy. I agree that it is ridiculous to compare a 1000 to 800 but the cat F8 just isn't there yet and poo's 8 is still being produced. Any rate it is going to be an interesting year and big cudo's to those who are the first year test pilots for Doo.

I'm not trying to start a pissing match but I just thought that I put this out there that you say that Doo keeps raising the bar but what everyone is forgetting is that from 2003 to 2006 AC F7's beat all Skidoo 800's. This is the first year the Skidoo can say that they have a really fast 800. I also agree that AC's F8 needs some more juice and hopefully they will give it some more juice for 09 so that they can compete against skidoo and Polaris in the 800 class more competively; however, Cat has said that the F8 will be faster this year, but I'm sure that it still will not touch the XP800R until they give it more HP.

This debate has gone on for years.

Yes the F7 is fast and they are easy to mod but to say it beats all Rev 800's is hilarious. Set up set up set up, the two sleds are very competitive with equal amounts of tuning.

And there's more to raising the bar than just going fast in a straight line. The twin spar is a huge improvement over the old FCat, just not quite as fast in a straight line.

yea...thats what i thought he meant...the new doo makes about 75 at the track....108..lol...my sled made 107 last pull and we expect around 112 on motor when done....my sled stock made 83-83.5 at the track...a stock f7 makes 68-70 stock....if the new doo makes 108 at the track stock then it would be the most powerful production sled ever produced....

Cat needs to get their emissions under control before they worry about looking for more power. If it wasn't for thier 4 stroke, they would be in tough shape. Do they even have any two strokes that will meet the next epa deadline, or even the current one?

yup. xp 600s will be calling out f8s.

maybe your sled is a P.O.S.??? just throwing that out there....

Yeah should have given more thought, my buddy's Rev 800 made around 108 or so but I forgot that was on a shot of Big Thunder NO2. It made low 80's off the bottle (with Bondi porting) if memory serves me right. I've heard of two XP's on a track dyno one was 77 the other was 80. How do you think you would have faired against an XP when your sled was stock? If you're only at 5 or so more HP and weigh 100 pounds more you have got your clock cleaned.

Gotta spend the big bucks if you want to stay in front of the little 800 huh Kitty Cat?

i was just explaining how track dyno numbers work...if the xp made 108 at the track it would make around 216 on motor and we know it makes around 150....so it would most likely make around 75 at the track....by the way,the 112 i'm looking at is before the 100 shot of 112 at the track is a HUGE number....i don't really mind you calling my rocket a p.o.s.....so let's do the math here 224+100= i think it = just tossing it out there....

ok good deal. at least you might keep up

wrong...i ran 2 of them when i had just a y-pipe and clutching....beat em both....xp's make 150...we have seen this number come from multiple sources....my sled made 165-166 stock....for the sake of argument lets assume the 100 pounds is correct...it takes 14.3 horsepower to overcome 100 pounds(don't argue that i will use you) 165-150=15....the 14.3 needed to overcome the lb difference is there...my numbers with a 3 arm primary(and clutched on track dyno) y-pipe and 2 degree key was right around 180 i think...give or take a few so don't hold me to the 180....i just know i romped the 2 xp's i ran.....by the way,they were doing a demo ride at the trailhead off 72 in kalkaska.after i rode both of em we all went riding...they are f7 fast dude...don't kid yourself thinking they are any faster...actually,they ARE faster than f7's but i never,ever thought f7's were fast...and i have owned 3....as far as the dyno numbers go for the xp go...there is another post around here somewhere about 3 shops(d&d being one of them) all pulling right around 150.one even pulled less...it's like the f7...how many you think pull the 140 as advertised??? i have seen tons in the 134-136 range.....i'm done with this topic...i know the xp will pull hard...i rode 2 of em and the ripped but they are a 150 horsepower sled.they pull like an f7 with an 800 kit...and f7's with 800 kits get stomped hard in the field....good luck with it man...i'm sure we will run into each other on otsego lake this winter....

another thing to think about is torque...the 1000 makes about 130 lb ft at around 6800 rpm....not sure about the xp but i would be very suprised if it made 105...my guess would be 103.

That is the big determining factor right there. Give me torque for a short run! Give me hp for a long run!

Means nothing, my 160 HP 800 ran with my buddy's 200HP F1200 and would go back and forth with another friends F1000 with a few goodies, this should not happen but it did. We won't really know how the XP will shake out until the snow flies. Who knows maybe the F Series sleds will be better this year.

As far as racing a prototype with a sled with a Y pipe and clutching, more bunk, clutching was off big time on the sleds my dealer had. They were getting now here near full shift. How you continue to compare your sled that has been tweaked is beyond me.

Look forward to seeing you on Ostego.

The big torque gain will I'm sure make up for the 100ish pound difference.

i know all about your buddies f1200...i'm done crunching numbers....look forward to the lake...

for some reason guys with modded 1000 cats like to call out stock xp 800s......

This is really funny can't wait for snow.

i think stock vs stock right out of the box the xp will walk away from the cat up to 80 or 90 just based of power to weight ratio.we all know the mach z ran circles around the f1000 so wait till 09 when doo brings out a 180 hp 450lbs mach,then you can compare those two sleds cause they fall in the same catagory.it's like comparing the new nytro to a 600 class 2 stroke,does not make sense to me.as for the fastest 800 there is know doubt skidoo has the ticket this year.i also own a 08'renegade 800R so i'll let you know if i get beat by a stocker this year..highly unlikely

show us were the f1000 make a 130 lb ft stock it closer to 118-120 at 162-165 hp and yes the xp is 101-105 lb ft and the hp is 151-156 . most likey the xp 800r will out run the cat and yes the top dog MACHZX1000 up until 95-100 but after that the bigger hp sled should go buy ONLY TIME WILL TELL.

Here is the info i was talking about. The 800r has 118 to the track and the 1000 Cats have 124.

I didn't read the whole thing but I do not believe that is the track HP, it's the HP measured at elevation.

Well I knew it was closer to real world than at the crank. The 800r is pretty close to the cat 1000.

That's why they had HP problems with the 07's. Their EFI system was very good for many years but is having trouble meeting both the new EPA requirements and producing HP. According to Aaen Performance, Cat was looking at coming out with a 2 stage injection system with the 07 F-chassis release like Polaris and Ski-Doo's SDI have but backed off for some reason.

I think both sleds are awesome, but I like the ergos on the Cat better. Anyway, how come I can push my car when it is in neutral? My car weighs 3,100 pounds. Based on your equation I would have 210 HP right? I'm strong but... lol Heck, my car only has 130HP.
