Discussion and questions related to the course Practical Dyno Tuning
I have done a fair bit of research and reading up on various types of dynos ranging from; Inertia, Eddy Current, Chasis, Hub, single & twin retarder ranging from many different makes and models.
From what I've gathered they roughly vary from:
15-20k for a older model 2nd hand
25-30k for a relatively newer 2nd hand model
35-80k+ for a new basic to fully optioned dyno depending on obviously if it's 2WD/4WD chasis or Hub and so on
I have gone with the option of converting an old 2WD chasis dyno.
There are many reasons why i have chosen to go down this path but one in particular is obviously the cost and satisfying my curiosity.
Now let's say you've decided to buy a dyno but aren't sure what you're looking for here are some things to consider.
1- What will be your primary use, 2WD or 4WD
2- Power output, Drag cars or mainly street cars, drift/circuit racing and so on.
Depending on the industry you're targeting the costs can vary drastically as stated above.
I have chosen to get into drift industry and street cars so a 2WD single retarder chasis dyno is perfect for me for the time being.
I have purchased a 2nd hand 2WD chasis dyno built by DDB Engineering in the 80s for around 7k AUD. (bargain price)
Some of you might be thinking, really? a old analog dyno from the 80s? what can you do with that?
Well the short answer is a lot.
Companies like Mainline or Dyno Dynamics can convert almost any dyno to run their software and hardware.
I have made some inquires and I have been given a rough quote of 20k+ for a 19" screen a basic computer to run all the software and accompanied hardware to control the retarder.
With some digging around I have located a place in Melbourne that has created a fully closed loop system that is completely customizable by the end user.
The unit controls the retarder and can be adapted to almost any chasis dyno at a very reasonable and affordable price.
The Dyno isn't complete as of yet, but i estimate it to be done withing the next 4-5 weeks.
Current estimated costs should be within the 13-14k mark and that's fully optioned and up and running.

Hope this info helps someone out, cheers
Make sure you keep us up to date with your progress once you're up and running!
I use dynertia 3 on my vane dyno and im very pleased with it. i didn't need much support but when i did they were very helpfull. And i noted a minor bug and the following day i had a new update to install with a fix. It is pretty big bang for buck IMO
I've been watching a youtube channel for a couple of years now where the guy rebuilt a Vane VP-950 and installed Dynertia. He has since been fitting the closed loop additions. If I could get hold of a Vane VP-950 or Vane 4000 for a decent price and fit a Dynertia3 closed loop system I'd be as happy as a pig in mud. The other option is build a dyno myself.
DTEC released the full closed loop brake dyno kit the other day.
Here's a youtube channel that has documented a Vane 950 rebuild and Dynertia3 fitting and adjustment https://www.youtube.com/user/blairo15/videos
