Discussion and questions related to the course Practical Standalone 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

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
