Engine Test Stand
 
Just joined the HotRodders !, i in the process of building a engine test stand ( getting to old to build the motors and then drop them in the car to get them running ) thinking about a 3' wide x 5' long base to start ?, i have seen a few on evelbay but dont like the chinese junk!, anyone have any plans to build the good old USA way or have a site you could refer me to ?

Thanks alot for any imput
JR

The ebay plans are pretty good but you can also look at www.sonnyshelper.com or www.easy-run.com. I don't think they sell the plans but you may get some helpful ideas by looking at them.

this may be a dumb question, but what do they use on the back of the engine to keep it from revving? looks like a bell housing with some sort of extension on it.

I built n engine test stand. The basis for the size was the engine itself and the radiator. The rails were based on the width of the engine mount:

I built a circuit and wrote a program to read data when it was run:

While not being a dyno I was able to do a few things, sort out a few things and learn a few things.

clear things up

looks like a great Idea but it is only for one engine.
What is that thing behind the gauge panel that looks like someone mugged a computer.

If you can build this, modifying for other engines is simply a matter of cutting and welding mounts which is little trouble.

The circuit board is an experiment I am working with. I am reading a number of parameters, displaying it on the computer and data logging it. I am reading:

Temps: oil, water, intake air temp
EGT on each cyl with peak indicators
O2
Rpm,
Timing
Throttle position
Manifold pressure

The programing is done through visual basic. This is a sample screen:

I agree the only upgrade to make would be to make an adjustable mout such that you could move the width or forward aft adjustment to accomodate other engines. That said, very excellent piece, nice welds and work. I'd take one of those!

Happy new year-

Thanks Happy New year!

Now that is an idea that would make a great addition to any engine stand.

one of my first rods had trans and diff temp gauges along with the more comon ones, you can never have too much info.

Great Idea

Engine Run Stands
 
Guys, I know not everyone can afford or needs to spend a lot of money on a run stand. I do use the Easy-Run Engine Test stand and have some experience in this area. I have made most of the mistakes and would be happy to help if I can. Thanks,

Engione Run Stand
 
JR, I just joined today. I am first, a car guy and I do build Run Stands. This post is not to generate sales... Many car guys only need a stand for 1 engine build and it would be foolish to spend big bucks. If you have any specific concerns, I would be happy to help pass on what ever I can and help anyone save time and money by passing on some of what I have learned by doing this. Thanks, Al

I'm building a dyno. I haven't finished it yet but I broke in a motor on the stand. I'd never run a motor on a stand before and it was great being able to have access to everything. Here's a link to a pic of how I made mine adjustable.

Minus the casters, I have less than $200 in it and still have half of the tubing left over.

gow589 01-02-2012 06:38 PM

I briefly looked at some of the photos. Very nice work. Is the bell/converter to be used for resistance? Fluid? How are you measuring tq?

Here's another pic.

I know the lack of bell housing is a bad idea. I'll have one soon. I built a water brake. Load is controlled by the amount of water in the brake. Torque is measured by the load cell under the torque arm. What are you using for data acquisition? I've been playing with some used Opto Snap and a DATAQ unit. I also have a MS-II hooked to the engine.

WOW, KA, that is a very nice package. Looks like your skill set out reaches many of us.... It is great to test run engines before you certify them as ready to go....
The guys on the forum have some great ideas. I'vetriedto keep our design simple and as universal as I can. We at Easy-Run have a lot of support from our customer base and that helps us pass along any info we may have to help. Thanks, ShopAl
