I started a thread here:

But I figured that the more idea's we get the better.
So let's open this up...

So you think you made some cool mod on your scoot.
You take it out and run it down the road and the butt dyno say's "YEAH!!!!!"
But often times the butt dyno is extremely inaccurate.
So, lets examine building your own Dyno
What?
Sound scary?
Perhaps not as much as you might first think.
What does a dyno measure?
Work.
So imagine a big fly wheel with a known weight and diameter being driven and measuring how fast you can speed up that flywheel...
Here is one fellas example:

sandblaster:
Of course you could incorporate things like your engine RPM, Exhaust Gas temps, Water temps ect.
So let's start with the basics.
A steel frame, a heavy flywheel on pillow blocks, a way to strap your scoot down, a trigger for measuring the flywheel speed, engine rpm, and how to capture that data on your lap top.
And how about some ventilation   :-o

sandblaster:
Oh... and some safety gear...
Fire extinguisher, ear protection, decking to cover most of the flywheel.... What else???

sandblaster:
Interesting site.
I will be looking at it closely later today...

I got to spend a day in Dave Roberts shop (ILR performance) with my tecate 330 on his Dyno. its a Land and Sea dyno.

it measures it at the crank.
I think you could make somthing simular with a hyd pump and valves and pressure sensors
