Question about a dyno

[farmtruc]

I posted this on the other forums too, just wanted to get an answer.

I have been researching dynos and I came across this particular dyno that sounded kind of neat. In order to make a run, you had to remove the wheels, then depending on application bolt on the adapters, then bolt these devices to the wheels. These units are the dyno.

Anybody know what I'm talking about, I just can't remember the name and the manufacturer of this dyno.

thanks,

Yeah lots of ricer shops around me use them.

I thinkit's called a Superpac...

there is a mobile dyno that comes out to HRP, that uses a set-up like that. costs about $75 to make a run. havnt done it, didnt know how reliable it would be.

I think Eric is right, its a Superpac. I know this was the type of dyno John Finnel (PV mufflers) was using. I am not real keen of bolting my truck up on one of these though. I would much rather put it on the rollers. IMO, a roller type dyno is much better for getting a more accurate "to the wheels" number.

how would it put a load on? Maybe some sort of braking depending on the weight of your vehicle. Just lease the DynoJet and be done with it!

You mean DynoJunk? hahaha.

This isn't directed to you hh, but there is no way in hell I'd ever buy or lease a DynoJet, the only reason everybody has one is they are cheap. In price and numbers.
99% of the shops that have them , have the inertia dyno, dynojunk is known for inflating the hell out of there numbers, like 10-15%.

My choice of Dyno will be the Superflow Dyno!

It's a true measure of tq and hp. I can list a bunch of well respected research, repair and tuning shops that are trading in there DynoJunk for a Superflow. That has to say something.

The next one up in my opinion would be the Mustang Dyno, but no way, it has the word mustang in it, lol. Land and Sea seems to have a selection of inertia and load dynos, I haven't researched them though.

10-15%that is crazy! If that is true my truck is making 290 corrected to the wheels, That really sux!

[farmtruc]

i just heard ppl say and seen a few runs that everytime they run, they are slightly different,

plus, talk about a sorry ass application for graphing out and plotting hp/tq numbers.
On silverado ss forum, someone posted a dynojunk chart and the scaling was off and the numbers were off.
The excuse (which makes sense) was the dyno software wasn't working right or scaled the plots wrong.

see ya,

allen

[Hay Hauler]

mine is a little funny since the scaling on the Hp is less than on the torque side. Its how the guy running the dyno sets it up. when he changedso they were the same on both side the scaling was right on (hp crossed torque right at 5250.

Hey guys I hardly post here but what you are talking about works pretty good. They use them mostly for AWD dynos (like C3 GMCs Audis ). I haven't heard of any problems on them except when you put a truck on them they usually cant accept a wheel base of 130.

P.S. The correct spelling is DYNOJUNK
