Bucket update

[Sully60]

This is what the Skunkworks Norf Welly Massif Bucket Factory is missing"

A home-made inertia dyno



I'm thinking that between us we could probably manage to throw one of these together. Someone on KB should be able to write the software and maybe even design the data capture set-up (the one they used is $600USD).

Cool!
I'm in, but I'll have to sell a coulpe organs or something to come up with any cash at the mo'

Does anybody want a set of hand made megaphones for a CB125T? Nah just kidding!

If we build it ourselves we don't need to worry about using archaic references like horsepower, pfft.
We could call them Bucket Watts, Gruntatrons, Whoahometers/second,


oooorrr!




Skunkabooms!

We could make the units really small, so that most buckets made at least a thousand Skunkabooms!

"Yeah the new carby gave me an extra 400 SKB's at the top so know i've got 1500 Skunkabooms, that dyno's fucken wicked man"!

BTW: This isn't a pisstake of the idea John, one question though, who's going to have it at there house?

Skunkabooms...Love it!!


It would probably make sense for it to live at SkunkWorks...space permitting obviously. Would be quite cool to make it portable though, we could take it up to the slipway for the under-privileged ones that don't have access to the bucket factory....and maybe even Ivan

I could probably get hold of an appropriately sized flywheel and we could probably find enough steel for the frame for fairly cheep...the hard bit would be getting the software and data capture sorted for cheap...to expensive to buy off the shelf. Bayden may be a good person to talk to???

I have been developing ideas for a water dyno but only for tuning (rather than Skunkaboom figures)...

But if we find us the steel and I'll be into trying this!

I did note the warnings about spinning large steel flywheels... and the engines are only kart motors (he shows one developing 13hp).

All the more reason to do it......I would have thought.

For measuring Skunkadooms you could simpify things by using a bike computer and a stopwatch. Time the engine to hit a given speed=gains or losses in power, which is all you really need to work out.

You fuggen Buddha!!

you did the 1000th post!!

.... well at least this thread will just die now...

It didn't die and I got the 2000th

Use a large truck engine. Custom shaft running in ball bearings clamped in the last two main bearings in the block. Bolt the truck flywheel to a flange on the shaft. Use the standard truck clutch, bell housing and gearbox primary shaft. It's pretty much all done for you.

You do need to count rev's pretty accurately though, if you expect the sort of resolution likely to "see" the typically small improvements from minor tuning changes. Counting is easy, just a proximity or magnetic switch stolen from an automotive rev counter. Plotting the trend accurately is the tricky bit. That and the sprag clutch.

John connor already has a homemade dyno with custom software.
Also, you used to be able to buy a dynojet dyno that was mounted on a trailer, Chris Sayles one was like that - from Dynotech, bottom of Ngauranga gorge.

Is it made from left over Terminator parts?

If you're going to dyno your bucket do it properly.
It's not kosher to use a commercial dyno, it needs to be made out of old washing machine parts and a bacon slicer.

[Skunk]

Who's got an old diesel truck motor laying around?

[Ocean1]

Might be able to organise something... PM sent

[quallman1234]

Ill have a look down at dad's work. Probably is something laying around.

Did some work on AJ's bucket (OK, I watched AJ work) to prepare it for the Taupo Road Race Spectacular. Pushed it outside after he left. When I came back the next day it was gone.

Hope it was you who got it AJ... How's the electrical thingys working?

[ajturbo]

ummmm...no..

and where's my van's engine???
