zx14's power
I attended the Atlanta bike show and spoke to a Kawasaki rep. He told me that the zx14 has 181-183 HP to the back tire. Has anyone have the bike dynoed yet? Does this seem accurate to anyone? Or is it a part of the sales pitch?

using the crank horsepower figures published by Kawasaki 190ps the zx14 will make approx. 169 to 179 RWHP

No way Jose...180+ RW??? Not without mod's, on a good day. Need pipe, Mapping, airbox/filter and some good Canuck gas to get 180+RWHP.

190 ps = 187.4 bhp w/o ram air
187.4 bhp -10% drivetrain loss = 168.7 rwhp w/o ram air
200 ps = 197.3 bhp w/ram air
197.3 bhp -10% drivetrain loss = 177.5 rwhp w/ram air
All just math based on Kawasaki's claims of course. We'll see what "real" dyno numbers look like soon enough.

Hope I didn't hurt your feelings blueford. And your right this is serious shit!!!! O by the way, I'm told by my wife a fresh pair of pink panties always make her feel better...You probably already know that from your experience wearing them though right?  Freakin cronie.

to zermatt your math is exactly correct. your only adding a 1mm bore with 0.2 less compression. Horsepower isn't going to go up significantly, but torque will...

I did not get that at all?
1mm bore added to what?
Please explain...

Adding 1MM to the bore, the rest of the displacement is all stroke! That's what he meant

what am i missing, the 14 is essentially a 1361 stroker (a bit less bore); it flies!

here we go again.
This is an old topic.
My 2cents:
If I were only interested in peak, and only peak HP, I would not hesitate to buy a 06zx10r instead.
167 RWHP some have dynoed, stock, on pump fuel.
100 lbs lighter too!
I would like to see whats under the curve, and beyond peak.- HP and Torque.
This would tell us everything about the character, and performance of it.
Nobody rides at peak all the time . Just drag racers.
"... oh where oh where could the dyno sheets beee?
.... oh where oh where lie the HP for me?"
good thing you can't hear me singin it out loud.
Goin stirrrr crazzzy here.
Don't mind me!

If you have ever been on a Busa...it's like that all the way up, but even more TQ at low RPM...

I guess I'm failing to see what it has to do with my statement that was replied to. Just missing it I guess... this thread didn't mention bore or stroke. The question was rwhp.

Zermatt.
Bore to stroke ratio lesson 101:
generally engines of equal displacement, can be considered square, over square, or under square.
Square meaning bore is equal dimension as stroke.
Over square meaning bore is larger than stroke.
under square= bore smaller than stroke.
most 4 stroke gasoline engines are square or over square.
generally engines of equal displacement with larger bore, provide more rpm, and it takes rpm to make HP.
Longer stroke will be less desireable for high rpm application, and provide more low end torque.
intake and exhaust duration, as well as dimension layout set the basis of the engines HP and torque curves.
There are many other factors, but these set the basis of the design target.
This is just a simple example of the complexity, and differing designs of internal combustion design.

No problem, I've read that before (in different wording) and it makes sense. No problem. I get it...
What I don't understand is this statement:
quote:

How does that statement apply to the very simple hp numbers that I copied/quoted/calculated in the post above it?
Is he referring to the increased hp vs tq when ram air is a factor? How would ram air increase bore or decrease compression?
Who's "adding 1mm bore with 0.2 less compression"? I'm not... why would I bore a brand-new engine? This is the point I am missing.
My post was simple math applied to Kawi's published HP numbers to help out those folks who can't seem to believe that this bike is only going to have +/- 169 rwhp stock when they put it on their local dyno (unless Kawi is sandbagging us...)

He is only indicating what Kawasali has done to the motor.
Ram air has no physical effect on the bore and stroke, only to flow to the engine (gas and air) which has a big effect on overall performance.
I will explain in a post a bit later...gotta go do some work now!

Misunderstood initial question.
ram air is poor mans supercharger.
The air is forced into the ram air duct , pressurizes the air box and this pushes more air into the motor.
an equal ratio of fuel is injected thus, increase fula and air are forced into the motor to create more HP.
Bikes are open loop systems.
I don't know how the ecm is programmed exactly but gear position, throttle position, barometric pressure, vehicle speed and other factors to determine how much extra fuel is required to maintain proper fuel : air ratio.

look the bore on the zx12r is 83mm. The bore on the zx14 is 84mm. The compression on the zx12r is 12.2 to 1. The compression on the zx14 is 12.0 to 1. I was just relating the differences in the motor and how it relates to horsepower. BTW the stroke on the zx12r is 55.4mm vs 61mm for the zx 14. Hopes this explains it....

Thanks for clearing that up Supra. I had no idea you were referring/comparing to a 12R, that's why it didn't make much sense. 
So you're saying that the 14 will be a serious torque monster? SUHWEET!!!
