I know that those dyno's use some form of brake system to simulate load like how would be in real life driving situations unlike the dynojets that don't simulate load that well due to inertia.

I know they would give lower hp numbers but i would sacrifice lower rated numbers for great drivability.

I would really appreciate any inputs from experienced tuners and dyno operators.

 

I know nothing about mustang dynos, but the DynaPacks are a very nice unit. Typically, you can set load from 40% to 101%, which means the dyno can hold the engine at, say, 4000 rpms while the driver modulated the throttle so you can adjust all points on your fuel and ignition maps - part throttle, WOT, boost where applicable. Also, since a DynaPack mounts directly to your car's hubs, meaning there is no tire noise, it's possible to hear all sorts of engine noises otherise drown out. THe solid linkage between vehicle hubs and DynaPack mean that it is possible to register single cylinder misfires, which are otherwise lost in the tire. Good stuff.

 

Lets add another dyno to your choices. Dyno Dynamics.

 

My only experience lies with dynapack. I can "street" tune almost all of the partial throttle fueling points in the fuel maps with setting the loading on the dynapack. I personal like eliminating the tire variable for numerous reasons with the hub system of the dynapack. I have tuned on a mustang dyno once, in comparision to a dynapack I am able to tune much faster with the dynapack. The software of the dynapack is killer as well. I am partial since I own one, but its well worth the money for being able to do your typical "street" and "dyno" tuning in one unit.

In comparision the dynapack software can be changed to read higher or lower than dynojet's, so it depends in what configuration you have things set. The dynapack is also much more sensitive to change, and I have been able to see knock and misfire very clearly after runs if its apparent. This is something that is hard to see with an inertia style dyno since the drums essentially dampen out fluctuations in cylinder pressure (knock).

In approximating "real world" conditions the loading of the engine through the dynapack is great, but you cannot reproduce the airflow at high speeds.

both will do what your asking for

FYI:
Mustang Dyno can;

Steady state
Vehicle simulation
Constant speed
Constant RPM
1/4 mile
0-60
Set distance traps/times
Manual loading

 

I have only experience tuning on a mystang dyno. Luckily enough, my friend owns one . Here is a good link for some comparison info.

thanks for the replies
I don't think there is a dynapack dyno anywhere is south florida
I know their is a mustang dyno at active autowerks though

ps. Arturbo what is different about a dyno dynamics dyno?

 

stick with the mustang dyno man

 

Thanks for all the Mustang dyno info, guys.

What he said.

 

i have only had nothing but good experiences with MDs, or mustang dynamometers, yes it is true they do read lower HP and typically the owner wilol tell you its not about the numbers but about getting it tuned perfectly, i agree. but yes an MD can give you great tuneability for partial throttle (street driving) because they load the vehicles weight into the computer and it preloads the rollers to that weight so you actually move the weight of your car on the dyno

 

the dyna pack can do everything the mustang can do minus the 1/4 mile and such... but thats what the track is for.

i can set the dynapack up to run from 7000 to 9000 and take 5 sec to do that pull to memic what you'd see at the track.

that and you dont have to worry about spinning tires or the car coming off the rollers.... its not possible for a car to come off of a dyna pack.

 

The mustang dyno can mimic track conditons too, JDogg.

Believe it or not, I know the guy who had the first 200+ mph Mustang dyno in the states. We were actually talking about it yesterday, I guess the NASCAR guys thought it was the coolest thing ever.

The Dyno Dynamics dynos are also good stuff. As far as I can tell, they are fairly similar to the mustang dynos. I do not think there is a AWD Mustang dyno, but I could be mistaken. I know DD makes an AWD version.

What's interesting is that the "lower" numbers that come off these dynos are generally more accurate than the higher dynojet numbers.

 

To address the original question, a dynopak is probably your best bet for part-throttle because you can lock the engine speed down and then run the car through a range of loads and then tune with the results.

 

i dont know about you but damn if i want a few straps holding my car on the dyno at 200mph....

if properly setup the numbers should all be the same... our dyna pack reads the same as the mustang dyno down the street as well as the mustang dyno that active autowerk uses...

 

I think that dynopak and mustang will be close. It's dynojet that's freaking high as crap.

We have an MD and were going to convert to AWD awhile back but I rather just stick to FWD and RWD cars.
