Horsepower Bet

[hab]

My friends and I have a little friendly bet as to how much horsepower a brand new KDX 200 has. Anyone have any idea?

 

[BucKat]

I'd guess around 37 ponnies

 

[clutchcover]

I'd guess at 34.

 

[Mac]

26

26 Dirt Bike Magazine, Sept 1999, P51
Mac hit the number right on.

27hp for the 220 according to their dyno run.

 

[BucKat]

27 at the rear wheel? or the engine.

 

[WoWman]

28, methinks.

 

[KDXer]

26 hp stock
up to 36 hp with FMF, jetting and porting

 

[Sage]

"up to 36 hp with FMF, jetting and porting "

New dyno spec's for my new engine coming soon, and it will be more than 36 horse at the rear wheel, see my picts for dyno run of my old (slow) engine.

 

[rvguy]

My certificate of origin states 33 hp.

 

[The Axman]

My certificate of origin for my 01 220 states 37hp.

 

[WoWman]

Those "certificate of origins" mean pretty much nothing. That is measured at the crank, not at the rear wheel.

How much would a Fatty pipe add to that 26 hp?

 

[Mac]

I'll bet removing the airbox lid, add any aftermarket pipe and rejet will get you close to 30.

I think Mac's numbers are right on. But, would higher octane make a difference?

 

[Robcolo]

Higher octane will decrease the power just a bit. Tuners mix a bit of "regular" into race gas to increase the hit on certain tracks. See Eric Gorr's website - there's a great article on fuels.

Naw, the only reason to increase octane is if your bike needs it due to engine mods such as increased compression, advanced timing etc...
