Default Engine test stand?

I've seen them for sale and many are brand(s) specific. Any ideas on what would be involved in building or converting an existing engine test stand for our engine?

It all depends on what you have more of, money or time.

Fixed your link ^^^^^^^^

CIS cars, should be easy.
Ljet, LH2.2, and LH whatever is for 35 pin S4+ maybe not so easy, I don't know how much they need to be tied into the rest of the electrics to be happy. OTOH it might be possible to use a couple of long extension cords for the two harnesses and plug into the brains etc in the car.

Maybe a better question is what would the goal be of an engine test stand?

I don't know. Isn't there a lot of torque that could flip it on its side if you work the throttle?

I would like to see anti tip/flip legs.

Just a thought

I could see them being useful for engine reconditioners, and used part vendors for checking that engines are OK for sale/installation ... but I think the best engine test stand for a 928 for most of us .... would be a 928.

What application are you thinking of Lex?

I like the "twin supper charged" chevy engine in the ad. I would think with the attention to detail they had in the ad, the engine stand can only be of the highest quality.

I've got a GTS engine on a stand that I bought several years ago (21,000 miles on the car's odometer IIRC) which I've refurbished (inspected, cleaned, new timing belt, etc.). Although I've never disassembled the long block, I have removed / refurbished the intake manifold assy.. Once I reinstall the intake manifold assy., I wanted to "bench test it" prior to storage or possibly offering it for sale. If the conversion of an existing stand made sense or if someone had an easy solution that I wasn't aware of, I might pursue it. There is a vast pool of information on this forum, so I thought I'd ask.

When I was 16, I had a job working in the truck garage, at a large distribution center. The rebuilt diesel engines got tested on a wooden stand....don't forget you are not going to be able to apply any load, so the structure only needs to be able to absorb a little bit of vibration.

Bell Housing and starter motor, cooling system and fuel system, and hook-ups to the injection system are all you need. Not much different than hooking up and engine to an engine dyno.

Pretty easy and quick to do.

Don't you need some sort of computer to time the injectors and spark?

Yes and no, it depends on what your working on. On a diesel all you need is power to run the starter and maybe the shut-off solenoid. On a carbureted engine, all you need is to power is the starter and coil/points, gauges can me mechanical as they have no effect on the running of the engine. When you get into FI motors you need power for the started, fuel and the timing controller, the related sensors in most cases get their power or signal through the controllers.

That has not been the case for over 10 years. You need an ECU to run the injection pump.

I have no interest in a GTS motor, but if I did, firing it up on a test stand after sitting for years would be insufficient testing before I would put it in a car. I would need to pull the heads and inspect the whole thing and put in new head gaskets and seals. Oddly enough those are my same requirements for any 928 engine that wasn't running in a car less than a year ago.
