Engine Dyno

[Woody.v8]

Has anyone made one or looked into it?
I would be interested in what you found with regards to the brake and load cell.
I'm looking at under 100bhp and same with torque.

I bought a Stuska engine dyno so I could map ECU`s on some silly engines, not rigged it up yet because I have seen a few engines grenade on them, figured a change of plan and I am going to put it in a shipping container with a camera, dont fancy eating conrods .

Just a basic waterbrake and analogue console.

Started one years ago but mate bought a Sun unit from the states end of home built, that was in the days of analogue instrumentation

Very useful info that cheers,
In my mind I was thinking that you had to directly measure rotational force but with a brake and a fulcrum on a load cell ....Sorted

Hi, very wise, because it can get a bit dramatic. I have a mate who worked in the test house at the works for the bus company and he said it can happen very quickly.

I think the correct technical term for that occurance is "Its pooed its pants" !

Yep, its definitely lost its newness.

How would you take drive off the engine?
Via the clutch or straight from the crank?

Interesting build here, but you might struggle to replicate it. I believe AvE did a a series for Patreon viewers where he made a small dyno from a brake disk to measure the oomph of battery drills, there's probably a lot of useful info there.

Just 2 seconds before the operator.

Never fails to amaze me how long they actually keep turning after that happens...

I did see a site years ago that described building a dyno out of a telma transmission brake, a torque arm and an electronic load cell but I can't find it now.

I haven't quite but my mate can grip 900mm in his chuck and 1500 swing I think

Maybe you could then. Most people don't have a giant live tooled lathe.

Oh I see, i thought I'd missed something and there was more to it?
He has done a good job though, but that is more a chassis/rolling road type dyno and I'm after one that just connects to the engine.

@Woody.v8 , this would be a good start . A cheeky offer may get it for a lot less http://www.ebay.co.uk/itm/Heenan-Fr...206647?hash=item1c82108b77:g:pNUAAOSw241YkJuj

Where would I start with that though?
Is there any info on how to pipe it up etc?
