Vane dyno differences?

It's been a long time since my last post but this one might get a few people stumped or interested.

Basically I am trying to find out what the differences are between a Vane VP950 and Vane 4000 dyno. I'm not interested in the oem analogue controls that come with them (although others may be so please feel free to tell us all what you know about them) but I am very interested in the actual dyno beds. The reason for this is I am finished moving from my old place to my new place, I now have a shed (4 bays), and I want an old dyno to refurbish that I can use for my own personal tuning as well as teaching Auto students.

So if anyone has any information on these 2 old dinosaurs of dynos I would greatly appreciate your input.

Cheers.

As far as I am aware they have similar roller design but the retarders are different, the vane 950 has a telma cc130 and the 4000 has a cc160 which have different torque ratings. I could be wrong I have only played with Maha dynos buy they share the same bed as lots of other dynos

Hi Casey.

Sorry for not replying sooner, I didn't get notified that there was a reply to this thread.

Thanks for the info. From what you say a 950 is a pretty good starting place. There was one of each for sale when I started this thread, the asking price for the 4000 was twice that of the 950 so I contacted the owner of the 950 the day after starting this thread and it had sold an hour before I rang.

The 4000 is apparently still available, and has a $10k AU asking price on it.

I know a dyno is a great tool but I'm reluctant to spend $10k on something that is close to 30 years old and needs at least another $5k spent on it for a digital conversion to bring it into the 21st century.

Cheers.
