That chart is not that far off at all - the HP numbers for the predator are with the W/B slip on. Without the slip on the ratio for the predator is 0.1012 or same as cannondale. My predator is faster than my buddies cannondale and I have the W/B so it makes sense to me. Also, in that link you can see they reported a 6HP advantage predator over raptor in stock form.

What i have seen with my own 2 eyes at my house on the dyno. (dyno jet dyno)

1. predator 39
2. raptor 35.5
3. raptor 36
4. DS650 40
5. 400ex 26
5. Z400 29
6. 250ex 12
7. grizzly660 29
8. sp700 26.5
9. 500HO 24


1 thru 9 were bone stock

10 piped and jetted raptor 44
11 piped predator 40.5
12 pammi 760, race head everything 52.9
13. micheal webbs banshee 59.2 (it is different now)
14. pammi 703 alky custom work 54
15. Alky DS with piston/cams/headwork and dual carbs 50.?

 

You know what sucks about all these numbers? A stock 500 twin snowmobile with power valves is probably in the 90s. I guess it must be liability concerns that keep the oems from building a REALLY fun quad!

 

Tell me about it. My stock 600cc ZRT Arctic Cat produces 118hp.

 

anyone any dyno on the 300 gas gas 52hp apparently

 

Stock HP by 14 Mins.

1. predator 39 PWR .093
2. raptor 35.5 PWR .088
3. raptor 36 PWR .090
4. DS650 40 PWR .086
5. 400ex 26 PWR .069
5. Z400 29 PWR .077


This is using 14 mins dyno numbers and stock listed dry weights!

All kinds of talk about HP, but what about TORQUE???? This is a very important figure to know as well.

 

Yeh I'm trying to figure out how to stuff my 130hp stock jetski motor inside my Scrammy frame. LOL

 

Like Stebob said, horsepower isn't everything. The horsepower of an atv or any vehicle in general does not tell the whole story. The torque of the 4-wheeler is just as important as horsepower.

 

Stebob- I have the torque numbers but would have to hunt them down

I do not have good torque numbers on the grizzly, sp700, 500HO or any other auto. The dyno jet will not give us torque until the wheels lock up. By that time the run is almost over. I make over 50 lbs of torque.
