The other day, I got the bike dyno'd at a local Daytona 200 event.

All-in-all I'm very happy with how things turned out. Bear with me - I don't own a scanner...

Bike Stats:
2004 Ninja ZX6R
Stock
480 miles



It seems, hp-wise, the new 636 is en par with some older (late 90s?) 750s I've seen, and quite competitive w/ the newer 600s, etc. I'm a numbers-guy, and figured some of you may be curious, so...I posted up. :D

thats sweet. man 600's make great power these days stock. way cool

 

I had to look back at the drag strip to see the 636 i was runnin :YEAH

 

bout time kawi stepped up to the plate. nice bike

 

why does the 3rd run have a slightly odd curve compared to the others?
and besides, you need torque info, horsepower is just a mathmatical calculation of torque, its not even real

 

Ok Kawi did not step up to the plate. Adding an extra 36 cc to the equation is not stepping up its trying to compensate for the fact that the ZX-6R couldn't touch the other 600's in its class. So they did as always they cheat the displacement to try and make it competitive.

 

you mean the green line? That's actually the 1st run...but to answer your question:

No idea...engines do that. From one run to another, the engine's computer can send different characteristics to how the engine is running. I don't need a torque number. (shrug). As for 'horsepower is not real'...?? odd comment.

 

The 636 isn't a 'class' bike; it's a 'street bike'. Your comments only carry weight if you praised Kawasaki for running their ZX9 in the Litre-Bike class. Please explain how Kawi was cheating the class running up to 90? fewer cc's than the rest of the field. On that note, I saw a zx9 w/ Exhaust and Factory jet kit put down 148whp the day I dyno'd my bike. Two bikes later an 03 R1 put down 146 w/ Slip-on and Power Commander. I'd say that's a 'draw' in terms of Mods vs. Engine size.

I'd bet 2/3rds of the Podium at Daytona last week would dissagree that Kawis 'can't touch the other 600s in it's class'.

If you don't like kawasaki - fine. Nobody asked you to. Just show the maturity to 'not like' them for the right reasons. Using the '37 extra cc' argument when talking about a STREET bike is like trying to excuse losing a street race because the 'other' guy had Nitrous. (shrug).

 

That's a pretty funny statement...but.... I'm sorry to say you are wrong my friend.

This 636 was run on a Dynojet Dynamometer. Dynojets are inertia-type dynos. Dynojets measure Horsepower by how quickly you are accelerating a drum to a given speed..... torque numbers are then calculated from the horsepower numbers through simple math...

Here's how it works:

horsepower = weight(drums) x acceleration x speed / 375

So you are getting exact horsepower readings down to 1/10th hp across the rpm range.

Torque is then calculated... since torque can be derived from HP :

torque = 5,252 x HP / RPM

so........ a Dynojet will show torque readings (for those interested) as long as the tach sensor is hooked up to the bike. It looks as if this 636 was not connected to the Dynojet's tach sensor since the graph is shown in HP vs. MPH.

 

now this whole thread went ova my head...but it all sounds good...
