Just ran across and article that explains some of the differences with Dynojet vs Mustang dynos.

I thought some of you might find it interesting as I realize more and more that the vast majority of people think a dyno is a dyno. I would like for more people to learn about the differences so when a member comes on here and posts how he made 320rwhp on a Mustang dyno that he doesn't get bashed because some other guy posted a 380rwhp dyno with the same mods but on a Dynojet.

that was a good read, thanks

 

Good info...

 

also... locked vs. unlocked torque converters.

 

Yes,
Great hopefully this cuts down on some confusion.

 

Good point.

This is the reason I take dyno's with a grain of salt until I know the specifics and even then until I see 1/4mile times and MPH I can't give 100% props.

 

So can someone explain why a Supra that dynos with 500HP and a Supra that dynos in 1000HP will both run 11's?

 

Easy... 60'

or

Peak Power vs Average Power

or

Driver Skill

Those are the most common problems with Supras

 

Definetly. If I've learned anything here, it is that!

Another thing dyno's don't tell you is 'acceleration'. That's why it's better to look at average tq, rather than peak hp figures.

One may have 500rwhp, but if there is no 'usable' power below that peak, then what's the point? I don't think this has to be preached to us truck members as much. We understand we need torque moving these heavy *** things.

And speaking of the locked torque converter vs. unlocked, how about Justin's (quikenuf) TR220 dyno. Did he really gain 80rwhp....

 

We actually do log accelleration per second on our Mustang Dyno. As far as I know this can be done on any loaded dyno. Usually we adjust the accelleration rate to a fixed amount per second for accurate tq comparison when tuning but I will do a before and after accelleration test if the customer wants it.
