Competition Which Dyno?

[Chace TX]

Kicking around the idea of getting a dyno. It will have to be portable, there is no way I could stay busy here in San Angelo. Looking at the Mustang MD250 right now. I know there are going to be lovers and haters of Mustang, that's fine just tell me why. What have you run on and what did you like or not like about it? Thanks.

I think you're gonna find that if you want to do a portable service, pretty much everyone is gonna expect a Dynojet style dyno. It's pretty industry standard, especially away from diesels.



I would imagine your main business would not necessarily be the trucks. If you are looking to make money with this dyno, the vast majority of customers will want a Dynojet style.



While they have been made into mobile units before, they are very big and cumbersome; but it can be done.

Mustang sets the industry standard.

I dynoed on a 1750 inside their plant last year, I was impressed, but when the exhaust hose blew off, the plant manager was NOT!



Ask for David, he likes Diesels. They can build about whatever you want.

The indusrty standard is the Superflow. No butts about it. Here are some of the reasons why. Mustang doesn't offer a dyno with big enough rolls to hold the HP, and there big unit is a cradle roll, major tire slippage there. And it is only a load dyno. A load dyno is the most accurrate, but u can burn a motor up in a heartbeat. The dynojet really even shouln't be called a dyno, because it isn't, it is an excellerometer. It hardly even applies a load and they and not meant to be used with diesels. U will have a lot of unhappy customers if u by a Dynojet. The best dyno out there is the Superflow sf-845 with the wide roll option. its rated at 1,400 HP and will do load dynos at a certain MPH, or it will hold u at 300 rpm a sec, what ever u set it at, just like pulling a load up the mountain. Its accurate, flexible, only problem is that it is not cheap.

This will be debated for years to come.



Mustang's MD-1750 has a 50" single roller very similar to the Dyno Jet 248. This is an inertia style unit in base form but can be upgraded to Eddy current loading capabilities. Drums weigh 3500lbs or 1750 lbs each.

Mustangs MD-250 is the smaller dyno that is used mostly in the mobile environment. They do have a MD-250-HD diesel unit too.



Dyno Jet 248 uses 48" rollers and is an inertia style unit. Cannot be upgraded to Eddy current loading. Dyno Jet does have software called Dyno Trac that is designed for loading vehicles based on RPM, MPH, braking % etc. that is for diagnostic testing.



Superflow - great unit. Superflow is known best for large truck - 18 wheeler type units - They are expensive but good units.



Unlike some will say, I believe the Dyno Jet 248 is fully capable in the LD diesel market. Although it cannot load a truck down, I am still able to see accurate readings. You will see how well turbo's light that you will not in a loading environment. Meaning, will it have lag from he!! or not. In some cases you may want the lag for the high rpm efficiency and in this case you need a loading unit to really test power. But, in most cases this is not needed. I have seen boost well above 80psi on my inertia dyno.

Ted Jannety has a Superflow almost ready to go.

Heh, I guess they are all the industry standard... . depends on what industry you are in. For automotive performance and racing, the Dynojet has it sewn up.



Perhaps in EFI development or other places where big loads are necessary, the more expensive units are used; however, call the performance car shops and ask what they have. Most will have a Dynojet.

Keith,



Do any of those companies above do Diesel work?

Again, if he's looking to BUY a dyno to try to MAKE MONEY, I would guess that diesels won't be the big part of what he does. While I wish that weren't true, the VAST majority of performance vehicles - which would pay for a dyno session - will not be diesel trucks.



That being the case, he'll have to cater to the people to make money with the thing.

This is some good info, I have noticed this running on a local 248, I've seen what extra timing will do in the way the chargers lit off like David is talking about, I know this dyno fairly well now and I watch and look at old and new dyno runs at the power it makes and when it makes it, here an example of the last one, I nick named it Baby Twins.

Thanks for the replys.

Some real good info here thank you. I have continued looking at the MD 250, and talked with several shops that use Mustang dynos. Gotten some really good feedback. This dyno will be used for everything, but mostly diesels. Starting this week I am making a few stops in Texas to try some different makes and models. The info received is exactly what I was looking for. I will respond more later when I get back in town. After making some phone calls and talking with different shop owners I am surprized at the number of different opinions.

Sorry of topic but... Man, those are impressive. Did you pick up the rpm on this one? Looks to have peaked around 2800? (guess of course) I'd kill to see that kind of number AND it looked like you had no problems spooling on those runs.

 

[Jim Fulmer]

David I actually thought they spooled slow but maybe it was just me, I started real low in the rpm's to see if they would spool any different but it didn't seem to. The RPM's you posted are about right for max power I usually run it up high to see what happens on the top, those runs were a new baseline on that dyno so when I build the new Twins I can see were the power goes to... ... started gathering parts now!
