Horsepower numbers don't seem right....

[shadow44]

If I had everything perfect ans was running on glare ice I think i'd see 115 to 116. This is dream meter and the conditions were far from perfect. If I was to slam te sled down and add a speed track I'm sure it was show over 120 dream meter speed. My nytro makes close to 150 for power. With a after market can it did make over 150. I'm sure with a after market muffler, speed track, slammed down, and running at a speed run event I could get 120 real speed. Not bad for a nytro.

Remember this is no xtx skid it's a shorty.

ya considering how high they sit and the frontal area (poor aerodynamics) thats not bad at all..

wonder what one of those new etecs could do? lol

I suppose, but it's not great either ( not cutting you or anything, just saying ) ....the previous owner of my sled ( who is also a close friend ) ran 110-112 on the dream-o-meter all the time...102-104 on radar. I realise aerodynamics play a big part and these sleds aren't meant for top end, but Ski Doo XPs are basically about as aerodynamic as Nytros...the sit high and catch alot of wind..yet at 150hp they will run 108-110 on radar...I guess they have a more efficient chassis? I'm still thinking about getting a set of custom rails from IceAge...same approach angle as an XTX but 128" long....there's gotta be something we can do to make this chassis more efficient.

the approach angle of the skid is the key...not the kick up or length....and the xp is way more aerodynamic..

Ive yet to hear of a shortie doing 115 other thans dirks....but I suppose with the right stuff he did so why not...
mine broke in without the simmons Im sure 120 on the speedo...

if the doo will doo the teens also Id be satisfied..

Not really, My best friend and brother in law each ride one....I ridden them alot....I don't see how they can be an more aerodynamic than the Nytro...the rider gets beat up by the wind on either sled...I'd say the Nytro has an advantage...look at the area around the light pod...that's were the wind get you most from the XP, the Nytro does a better job of splitting that wind. My buddies Doo ran 119 on the speedo..109 on the gun ( same day results )...there's gotta be a way to make our sleds ( with full mods ) run at least that speed...other than adding boost lol.

I agree. An 2008-2010 800R Renegade will only do 105 toped out on radar and that's being optimistic. Most will run 98-100 on radar. Now a shorty with the different gear change or stock gearing which is geared 2 teeth higher then a gade, will run max 110-112 on radar. They do not have any top end. Now the e-tec is reported to have a good 4-5mph more top end, then it's predecessors, so it will be good to watch. The Nytro XTX can definetly run with a 2008-2010 800R gade or 120" when equipped with a header and filters etc.... I have raced 2 800R shorty's and beat them both all the way to 100mph and I was ahead by 2 lengths and I believe I would have pulled away on one of them on the very top end, since it was geared down and clutched.

I don't think the Nytro is any worse aero, then the XP. The rider forwad design has alot to do with it, the driver being higher up on the sled and over the front tips of the rails, unlike traditional sleds, where you are tucked down more and hanging near the back of the sled. A;sp, those sleds typically were lower to the ground. As noted before, the skid also does not help the Nytro (any) for really good Top end, like an Apex. The XTX is better, but there's room for improvement.

shadow, your speedo is off by alot, since mine is only 4mph off to my GPS.

My sled runs 112 every time out and that's with Drag and fly clutching. Stock clutching I'm guessing id' see more like 115 plus. There is more there in my sled. The day i was getting 113 with Two speed clickers the conditions were terrible and I was under reving by 700 rpms. So like i said there is more there.

the fact is people don't see much more then 102 to 105 on 121 Nytro's and Mine shows 10 MPH more with a weight 'drag and fly' that isn't known for top end.

Could be SF...I'm only going by what my buddy said when he owned it..I've barely even looked at it...I'm hoping it pulls some decent speed this season, I know it feels real strong in the mid and top end...hopefully my lake gets frozen soon nad we get enough snow for lube and cooling...I have alot of testing to do and the radar needs to have it's trigger pulled lol.

apples to apples look at the front of the xp vs the nytro...

the area behind the shock on the nytro is like a flat sail...the headlight is realtively flat...even the windshields dont seem as aero...the xp has that stealth thing going and most importantly sure seems to sit a lot lower?

Ive been told the biggest reason for lack of top endisnt the aero on the xp its the TRA clutch...and in drag race circles is known for the holeshot but gets it caught at the line due to its top end???

also...one of the clutch tuners showed me some dyno's on the xp 800 whereas they determined the motor is moving in the chassis...theyve witnessed it while on the dyno...maybe needs a motor brace for that..

isnt a xp faster to 100 than a gade? what about after? what easy gains can be made/had on one?

 

[bottlerocket]

Steve you need to ask these questions on dootalk...lol

 

[Turk]

I race all my buds 800 doo,s 100 times a day every day. We got renegades; shorties everything in the mix. Every shortie is faster then the gades down low/mid & up top. These are all 08-2010 doo,s & 1 is an e-tech 800.Same as the 1200,s; the shorties run away from the long tracks everywhere.

I dont think so...all the yama-doo guys are right here!

thanks Mike how'd that etec run compared to an 800r???

 

[Turk]

The e-tech was slightly ahead when new by just a tick. After 3 tanks of gas it had 2-3 lengths on our fastest 800R in 1000'.The e-tech was completely stock & the 800r had minor mods.

I heard a rumor that the adrenaline shorts were for some reason faster than the X's....maybe the 1" track vs the 1.25" ??

 

[Turk]

We have a guy in our group that buys a new x every year. It,s allways 100% of the time the fastest sled & he can not tune to save his life!
He did pony up to the 1.25 track tho.

why do you think a X sled would be faster than the adrenaline sled short to short?
