I posted this up in the Can-Am forum, but they are to busy with their Ds650's, so i'll try here. i know the outy 800 makes 62 hp, but I can't find the rated hp's of the other big bore utes. The manufacturers don't want to list this on there website spec's and I thought maybe somebody here could help.

Thanks,
azoutty

 

I forget who it is, but someone on here has access to all the numbers. I hope they chime in for you. These forums are usually pretty good. Sometimes you have to ignore the rest of us, or jump right into the chaos, if you want to!

 

Polaris's 800 I believe makes either 55 or 58hp .. but keep in mind it's only a wee 760 .. just wait till they get it up to a true 800!!

"Here's a list i've been compliling for a LONG time (some may be off a little, but most i have checked with more than one source):

Arctic Cat (suzuki engines, except the kawi-powered V2, and arctic cat's own H1):
500: (2003 and up have slightly detuned Vinson engine): 32hp @7000rpm, 34 lb-ft torque at 3500rpm (pre-03 had 28/30.5)
300: 14hp
650 V2: (close to prarie 650)

Bombardier (Rotax engines):
Outty 800: 62hp @ ? rpm, 52tq @ 5500rpm
Quest 650: 42hp
Outty 400: 28hp

Honda:
Rincon 650: 39hp
Foreman 450: 24hp
TRX 300: 16hp
400EX: 27hp
300EX: 21hp
TRX450R: 42hp (questionable)

Kawaski:
BF750: 51hp
Prarie 700: 46hp
Prarie 650: 42hp
V-Force 700: 51hp

Polaris:
SP700: 45hp
SP500: 30hp
SP500 HO: 38hp (same as scrambler 500)
SP800: 55hp/50tq

Suzuki:
KQ700: 49hp
KQ300: 14hp
LT500: 53hp
Eiger 400: 25hp
Vinson 500: 34hp

Yamaha:
Grizz 660: 42hp/35tq
Warrior/Wolverine 350: 18hp

These are brake hp ratings (BHP) from the factory... there will some variances from quad to quad (usually within 1-2 hp/tq of the above ratings). Hope this helps someone out there.... "

This part from Arcticchat from green goblin

Alot of new quads coming out. Here's too name a few.....Bomber 800cc HO, Bomber 650cc HO, Rincon 775cc etc....but how do they really compare to the V2, H1, Brute 750, P800, KQ700 in terms of gross HP at engine by weight stock.

Though I would start a list, but will need some help.

Outy800, 62 hp at 639 lbs = 0.097 hp per lb
Outy650, ?hp at 649 lbs

BF750, 51 hp at 600 lbs = 0.085 hp per lb
P700, 46 hp at 600 lbs = 0.077 hp per lb
P650, 42 hp at 600 lbs = 0.070 hp per lb

AC650 V2 SE, 42 hp at 711 lbs = 0.069 hp per lb
AC650 H1 SE, ?hp at 693 lbs
AC700 EFI SE, 49hp at 694 lbs = 0.071 hp per lb

Rincon650, 39hp at 600 lbs = 0.065 hp per lb
Rincon700, ?hp at 600 lbs

SP800, 55 hp at 770 lbs = 0.071 hp per lb
SP700, 45 hp at 770 lbs = 0.058 hp per lb

KQ700, 49 hp at 603 lbs = 0.081 hp per lb

Grizz660, 42 hp at 600 lbs = 0.070 hp per lb

 

FYI trvman ..

The Warrior / Wolvy bhp @ crank is a touch over 24. 18HP is the RWHP of the Warrior, not sure if the wolvy's transmission is quite that efficient, but would be close at any rate.

Most of the other numbers you posted there are crank-horse measurements ...

 

Thanks, trvman. I did several forum searches but it didn't turn anything up. This is exactly the info I was looking for.

outlander 650 is claimed 52-54 hp at crank, the 500 is 42-45 hp i believe.....

 

Bottom of the page lists several years. Look for yourself, under the OFMC/ATV/eGC heading
