Guys, keep in mind these will not be exact ratings, it's not possible to produce thousands of engines of the same displacement at the exact same output. There will be minor differences, but not more than a couple hp either way. Believe me, i've been involved with manufacturing for quite some time and there will be some difference, but within a fairly accurate range.

The only way i'll believe the ratings for the SP800 and KQ 700 you posted is if that's for very high elevation, either that or someone read you the wrong values (36.6 seems closer to a vinson, and 45 seems closer to a SP700). I know for a fact that the KQ700 makes appreciably more power than a Vinson, Quest 650, Prarie 650, Rincon, etc despite the low end lag they have. KQs are very high 40s, SP 800s are low to mid 50s at close to sea level. Check with other dealers, there are 9 dealers from all makes within 40 miles of me and after contacting them, i have yet to see large differences (>2hp) from the ratings i've posted. From dealers to individuals posting their certificate ratings, these agree. I live at an elevation of about 130' above mean sea level. That's why i'm trying to get more members here to post the hp reported from their certificates, to see how the ratings may change with elevation.

HP from the crankshaft is what we're looking for. Wheel-dyno graphs for most ATVs are garbage, especially for CVT trannies.

 

I got all those ratings from my dealers and when I looked online for atv reviews i got the same thing but the king quad is the opnly one i did't get from my dealer i got it from the tfi web site and they did runs on sum machine and thats what they got.
