Has anyone ever made a simple dyno that you can build at home for basic numbers read out on a PC (personal computer)?

Bruce Crower built one in his home shop. It hooked up to a water hose. It's kind of cool. It will only absorb a few hundred ft. lbs but it gives you enough to load an engine and break it in. It has a strange (sp) gauge on it. It's only about the size of an auto trans torque converter.

You might want to check out LandandSea dyno's they make one that will hookup to an Outboard propshaft it could probably be modified to fit a crankshaft.

Thanks for the info. That LandandSea dyno looks pretty cool. If I thought there would be enough interest in it being used and pay for itself, I'd think seriously about buying one. Rex Hutchinson is the only Dyno locally and I've heard he charges from $800.00 on up.

I'd like to find out about that home made one though, too.

As far as local dyno's, I've heard Joey Grose (Lodi, very cool dude) has his new dyno running. His dad Ron has one as well but not sure he dyno's stuff he didn't build. Here in the SF Bay area I've used Dave's Engine in Newark. Dave is also a very cool guy and easy to work with.
Most of the dyno sessions I've done cost $625 and up. Make no mistake, these guys are doing you a favor at that cost. Dyno's cost a lot to buy and maintain. It's really hard to come in, set up, do a basic dyno session and pull the engine in a 8 hr day. When it's said and done, it's hard for a guy to get $75 hour for dyno work. That's not enough to keep the doors open in most shops around here...
You want to know more about dyno's, go to Superflow's website. I've been to their facility in Colorado Springs... gearhead's heaven. Good luck...

Land and sea not only makes all kinds of brakes for different applications, but will sell you only parts if you want to put it together yourself. Their dyno program works very simply with a PC. It would be easy to make one with parts from them.

It's not really cost affective to build a dyno in most cases.

If you're going to build one that will be worth using you're stilling going to be spending thousands of dollars. Plus having to dedicate the space to building a safe, and consistent dyno cell (and legal based on your local laws). When dyno testing at a shop you're part of what you're paying for is the operators expertise in running the machine, and tuning with it. Lastly if you build one "For fun" and start running friends engines, what happens when one breaks on the dyno?

LOL Most hobbies aren't cost effective but a lot of fun to say you built it and it works like it's suppose to. There's only one friend I'd even consider running a motor on a dyno for and he's not building anything nor do I think he ever will that would require a dyno. This was a project just for my own enjoyment.

Everynow and then when I dream I check out the classifieds over here to see what I'd buy:

Ah, the SF901. It was the industry standard for years. State of the art back them. It is more than adequit for most applications now. It is not accurate enough to find nascar sort of differences. Drag, pleasure, street pealer. Can't go wrong.
17 g is not a horrible price. I'd beat him down to 15g and buy. LOL

I ran into Richard Lee at the Father's Day roadster show in Pomona, he said I could have(to buy, not free) my choice of 3 different dynos he has. You could look him up at Lee Performance in Elsinore, CA

Yea, when I'm avoiding work (like right now) I do the same. You ever notice everything on Racing Junk you might be interested in is at least 1500 miles away from you... Not sure if this is good or bad though...
Well if you decide to buy that dyno let me know. It's only 2 hrs from me and I'm sure we could work out something and I'll haul it out to you. I need to find a reason to make it out that way to one of the gatherings anyway.
