Someone needs to make some vinyl cut outs so he can put them on the side of the control cabinet!

And here I was, all excited and proud of my new lift & compressor...

That's awesome. I need one now!

Super old post but it is mine so that is ok that I bump it right? Anyway...finally got the dyno up and running.

I added new electronics and data recording from performance trends. They have a eddy brake controller too that is VERY new so still dialing that in. But it does work. Which is cool.

Finally getting some good data out of the machine and all I can say is it's really cool.

Some pictures...

My m42 powered 2002 on it.

and some DATA This is two graphs of the same car when the engine was just warming up and then fully warmed up.

Stock chip vs a "tuned" chip

stock report

tuned chip report

and just the tuned chip graph

I am still learning how everything works and all the info I can get from it.

I am readying AFR from the tailpipe on this car and I think it is a bit leaner showing that what is reading happening.

What type of dyno is this? Clayton or some other brand? How difficult was it to integrate the electronics?

Are you power limited on the Eddy Brake?

Yes it is a clayton. VERY easy to use the new electronics. Magnet on the dyno wheel and then a sensor. Then connection to the load cell.

Eddy brake works off that same sensor and the computer. Two wires to the brake itself.

This dyno from clayton was rated at 700hp but who knows what sort of power it will handle with the new electronics. The controller uses a PID and then a DC motor controller. Controller puts out 6amps and around 120v (I think). Performance trends said that others have used two DC motor controllers connected to their boxes to get more amprage into the eddy brake. So...if I come to a point I can't hold back the power I could go that route.

This is too freakin sweet. How much did it cost to get it running?

I can't think of any practical reason I need that, but I still do.

The front roller is the measuring/loading one, right?

Did you have to check the rear roll to make sure the load on it is as low as possible- bearings and whatnot? That way when you do a load cell calibraiton- and then the power calibration- the numbers are correct.

Oh, and the VERY little bit I've done tailpipe measuring of a/f, it's quite a bit leaner than in cylinder. Depending on the pulsing + any leaks- well...

Great find. IF (which is not going to happen) I was keeping my racecar, I would totally bring it up to tune it.

Do you know the model? There's one for sale locally (think it's an SPX - something like that). Wondering how similar it is.

BTW, assuming your shop is a self shop, and all not for profit...

You paid some decent amount of money and time into that cool tool/toy.

I'm 100% sure that if you had a GRM weekend up there, you would find people who would be happy to hang out and even donate some money to help you develop that into a nice to(y)ol.

For that matter, you would beome best friends with people if they got to buy you a case of beer for some time in September before the challenge.

Heck, even if you were a for profit group, you would get folks who would put some work into it for some spinning time.

I notice the local tractor repair place has one that hooks up to the power takeoff. Its on wheels and they roll it out of the corner when they need it. I thought it would be neat to pick one of them up and build a hub adaptor or something.

I have around 6k into the entire setup....maybe a little more with ramps, straps, etc

The rollers are linked with a belt on the far end. If you look at first post of this thread there are more pictures of it.

The software takes all the measurements for the moving parts for straight Inertia . The graphs above are actually straight Inertia accell runs. When using the load cell it combines the Inertia and the data it gets from the load cell.

I haven;t read much about tail pipe vs a bung closer up but I expect it is reading way lean.

It is a 20-1213

I do run a shop so this is something I hope to make money off of but it is not the main source of income for the shop. So runs/tunes will be lower than others.

With that said if there are people in Michigan I am ok with doing dyno day or pulls, etc etc. I am still dialing it in and learning all the ins and outs of the software. But so far things are going great, such a fun tool

Fun fact: The Bay City Rollers were from Scotland. They threw a dart at a map of 'America, and it hit Bay City Michigan-hence the name. Still a great name for your dyno.

Ah- did not see that the first time around- thanks.

The TP bung thing will change depending on the car and set up- 4 cyls will pulse more and pull exhaust back up- single bank V8s will be worse. As long as you are aware of it- the rules of thumb will be tough to use- since the error will depend. But it's still a good tool given nothing else. One "nice" thing for you- if you can find the same sensor to use in a real spot- you are already set up to plug it in and record.

As for a Michigan Day- IF I were still racing, I'd be happy to drop some money for a fellow poster's dyno time.

Man I am digging this thing. Did some pulls with my cousins 84 mustang GT350 today. Non intercooled turbo 2.3L.

Anyway...the power it made was dismal as shown in the chart below. Also was logging boost and it was only making 2.8psi at redline. Should be 8-10psi.

Did a little looking and find that the actuator arm to the wastegate flapper wasn't connected. The pin was broken off. My cousin has owned this car for 15-20 years and he bets it has been this way the entire time.

I am excited to dyno again when he fixes it.

Did some pulls today with a turbo ed m42 in a 75 2002....boost was a little higher than it should be so numbers are a little higher. BUT things are looking good.

Boost is a little high on this one so it is a little leaner than I would like. Need to adjust the preload on the wastegate and/or richen the tune up a bit.
