DynoJet vs. DynoDynamics
A dyno is a tuning aide - nothing more nothiong less
What is relevant is
That the load is repeatable and that the machine has good resolution to quantify gains and losses
A dyno jet is around 60 - 70 K
Dyno Dynamics is just about double that
To me the power figures the machine spits out are meaningless - (although I understand that many customers are interested in them)
The main use of a dyno is to properly tune a car in a controlled envirnment

but hey, its just an opinion.
I actually was in the process of acquiring the DD, when we went with a mustang... it fit our overall picture better.
but i never even considered a dynojet... and a dynapack, what a pain.

here it goes again the never ending dyno debate 
there's no 100% acurate dyno and alot of stock cars put down different numbers depending on the tolerances inside the engine and outside conditions. Both affect hp and tq greatly

Dyno numbers are just numbers people, get your cars tuned go out to the track and post up some time slips......
Traps are a good indicator of the power the car is making
low e/ts are a combined indicator of driver skill and a bit of the cars power too

Agreed, but Dynodynamics is pretty much spot on from my personal experience.
Mate, what are you smoking...??????????
All of my dynos except one are on a DD...
watch and learn... (1.1 correction all of them)
intake, mbc, fp, dp, hfc, catback, e-flash, 22psi, 93 octane
as before plus cossie cams, head studs, custom dynoflash, leaking greddy type-rs bov, same gas, sane boost
as before plus txs fmic, megan o2 housing, forge wastegate actuator, stock bov, 23psi boost, 6-8 knocksums, kept pulling timing...
Saturday adstusted actuator, nisei piping kit, randomtech metalic substrate high flow cat (rated at 617cfm!), custom retune...
PERSONALLY this is how i use the dyno...

Use the dyno to see what kind of gains you have made from your mods. The proof is on the tracks!! (unless you can't drive.)

But here goes, DynoDynamics is not spot on, Dynojet is not spot on, Mustang dyno is not spot on.
NO DYNO IS SPOT ON..
Car makers use engine dyno's, not chassis dyno's. They publish numbers by the amount of power at the crank.
Chassis dyno's measure the power at the wheels. There is always going to be a difference, and you could have the exact same dyno's, run the exact same car on both of them and get a completely different number.
Dyno's are tuning tools, they are used to give a tuner a controlled, repeatable environment in which to tune. That's it, nothing more.

I'm not even sure I want to reply in this thread...

I'm done asking anything about whp #'s, this **** is making me ill. I could care less, I just wanted to know why DynoJet reads so high and why DynoDynamics is more accurate. Please Just delete this thread. I could care less about any of this **** anymore.
