Anyone know them
I think the sp 500 is 38 hp at the crank,

How about the 700 efi and 800 efi?

I know the march 2002? issue of atv mag has the rear wheel dyno of the sp700 at 30hp at the wheels.

Anyone know any other official #'s

 

do a search on here but go way back.it was posted back around 01 or 02.

 

SP700 makes 46hp at the crank i belive
SP800 makes 58hp at the crank and bout 42ish at the rear wheel i belive

 

i didnt know the 800 had THAT much more hp than the 700[img]i/expressions/face-icon-small-happy.gif[/img]

You need to go by crank numbers because the CVT gives off inaccurate readings for the rear wheels.

I heard the 700 carb was 45 and 700 EFI 48 hp.

my dealer told me that he dyno'd one and it said 58, he could have said 48 and i miss-heard him, but i donno

you can find it along the bottom of the top tool bar, they have 700 carb and 800 EFI dyno numbers.

 

54.8 HP for the 800, so basicly 55 HP

 

here is a copy of an old post from 2002

I'll give it a whirl:

250 = 22 hp

300 = 22 hp (but more torque)

325 = ?? hp

400 = 36 hp

425 = 27 hp

500 = 32 hp

500 H.O. =38 hp

700 = 45 hp

The important thing to remember is that these figures are taken at the crankshaft. Todays dynos aren't really set up to give an accurate compairison between manual transmission machines (hp and RPMs) and CVT machines (Horsepower and ground speed)

 

form another forum...

One of the reasons, besides normal loss of horse power through the CVT, is the fact that a dyno can exert more force on the quad than the ground normally would. This forces the CVT to slip and give a false horse power reading.

All that being said, the real reason for using a dyno is to get a starting point and find improvement. If that means improving how your CVT works to get the power to the ground and keep it there, then it's still a valuable tool. I would not expect a built auto to throw out the same numbers as a shifter, even if it's more powerful and faster.
