Dyno build

swarfman64 · February 20th, 2015, 06:59 AM

I must be crazy, another project!

For those interested keep your eye on my blog for a motorcycle dyno build.

http://swarfman64.blogspot.com.au/20...rtia-dyno.html

This one won't go as fast as the turbo gpx build but I will try to keep it rolling.
Most if not all will be built at work so actual paying jobs will hinder its progress and I'm limited in after hours time (that family/life thing).
Basically I'm building an inertia dyno with Performance trends logging. I've got almost everything gathered and time is really the only limiting factor.

What's a roundabout cost? I have tossed the idea around

1000 for logger, 1200 steel (hollow bar was 800 bucks alone) another 1000 for bearings,computer, paint etc etc, I'm thinking 3000 to 4000 doing everything myself. It will add up if you have to pay someone to build the roller. There's probibly 2000 in machining that alone. All Aussie dollars.

dyno session is about 350 buck here, so by the time I've tuned my bike (about 10 tunes) and I've covered the cost

Copied from
http://en.wikipedia.org/wiki/Dynamometer

"An 'inertia' dynamometer provides a fixed inertial mass load, calculates the power required to accelerate that fixed and known mass, and uses a computer to record RPM and acceleration rate to calculate torque. The engine is generally tested from somewhat above idle to its maximum RPM and the output is measured and plotted on a graph."

Does that mean that the equipment will only measure power output during acceleration?

Correct, it does not have an rpm hold feature. A typical run depending on dyno design and engine HP will be 6-10 seconds. There are advantages and disadvantages to both types. In reality an inertia dyno will do everything I want and the cost and setup is a fraction of a braked dyno. Also calibration is easy, you only need to know the moment of inertia of the rotating mass and rpm.

Very interesting!

I have never seen one of that type.

Thanks

Andrew again a good plan and project from you but may I ask if you plan the usage of a 'CO-Gas Analyzer' also?

swarfman64 · February 22nd, 2015, 08:52 PM

Not at this stage, just a wide band through the logger. As time, need and money show themselves I will option it with some good accessories. For now I'll get away with the basics.

swarfman64 · February 26th, 2015, 11:28 PM

A little update is posted on the blog. I spent some time today building the chassis.

Your a dick, go away........

Seriously that is badass!!!! I fortunately have a dynojet dyno I can use but its at my buddys shop, would be nice to have one in the back yard!

swarfman64 · March 3rd, 2015, 12:04 AM

This dyno isn't doing work productivity any good. Oh well.

IMG_4318.jpg Roller is assembled,260kg, almost 12kg/m2 inertia, 600Hp capable, should just be big enough for tha turbo ninja.

I spend everything I can on income producing assets from hand tools to big machinery, Once the cycle starts it just keeps growing.

swarfman64 · April 1st, 2015, 03:35 AM

A little more progress, Work is keeping me busy but I'm getting there slowly.
I'm at the point in the turbo 250 where the dyno is needed, see what Easter brings

Somchai · April 1st, 2015, 04:40 AM

I don't say nothing no more before the dyno is completed, I'm speechless...

swarfman64 · May 29th, 2015, 03:15 AM

Another update. I found a little time in a hectic life to begin the data logger installation. I'm waiting on a few cables but should have the wiring complete in a week or so. There's a UPS in a drawer and a dock to take the laptop. I have a portable two plane dynamic balancer on its way from Europe which I can use to can check the roller balance in situ.
The banners are made and off to the signwriter, they are fastened at the top but clipped on the bottom to give good access when strapping. That will leave only the brake disk and master cylinder (for slowing down between runs) to do.

Impressive! wish you were close by to break that bad boy with my 12ft/lb of torque!
I actually brag about my 144 inch lbs

swarfman64 · July 25th, 2015, 03:40 AM

I'm back. well not really....As you get older "stuff" gets in the way of a good project. The turbo is on hold until the dyno is buit and the dyno's on hold till the balancer is built and its all gotta happen in between Kids, work etc etc money permitting. So, what I have managed to do is build the dynamic balancer for the dyno inertia roller.[ATTACH]IMG_5124.jpg[/ATTACH] I still have the electronics to sort out but the mechanics is done. I've built it so it can be used at work for other things like spindles and shafts (my excuse/justification to build it). The dyno is 100% complete now with the brake fitted and the wiring finished, I've even fired the computer and the two screens up. The roller balancing is the last thing to do. Its all here if your interested. http://swarfman64.blogspot.com.au/20...-balancer.html

choneofakind · July 25th, 2015, 11:30 AM

might want to have a top half bearing that can close over your shaft. Just saying, you don't want to see what happens when that shaft hops off of your balancer at speed.

Our balance machine at work has top half bearings that clamp over your shaft. It's also got a brick wall built around it... Just in case. Then again, we balance impeller/shaft combos that weigh upwards of 100 lbs at anywhere from 300-5000 rpm soooooo... Idk what your setup weighs that's being balanced but if you're going to use this thing at work, I'd hazzard a guess that OSHA rules about machine guards and safety measures should be followed.

dcj13 · July 25th, 2015, 12:55 PM

Not gonna use Dynabeads to balance it?

(kidding, of course...)

swarfman64 · July 25th, 2015, 04:12 PM

yer, I have the top safety hoops fitted, the photos were taken befor I fitted it.
Your rite, there limb smashing/wall removing energy in this thing.

swarfman64 · September 3rd, 2015, 04:16 AM

Dyno up and running. pics and video soon

First test to 150kph with my 500cc café racer strapped on, no vibrations and good clean data

Somchai · September 3rd, 2015, 05:06 AM

Hey Andrew, nice to see you back again and congrats for your running dyno

swarfman64 · January 2nd, 2016, 04:19 AM

I had forgotten about this thread, oops.
Here's a couple of pics for you. I'm trying to get some video over the next week.
