Dynodynamics Vs Mainline Dynolog

[Mik]

Well how does this grab ya...Carlos from Millenium Motorsports ran 599kw at Queensland 2 days before Autosalon on his Mainline dyno...and at the same boost levels ran 601kw on Autosalon's dyno.....he must have the "special" software too!

Mainline dyno's even run the same no matter if its 2WD or 4WD...we proved it in front of hundreds of people at Final Battle...there was 1kw difference between the runs.

I think what Mik is trying to say is Croydon's dyno is happy...if its so happy i should be rolling almost 520AWKW......i think im gonna have a word to Jim about my deflated power figures.

You thought wrong Paul. What I am saying is that it is fairly common knowledge that dynologs read lower than dyno dynamics. (And dyno packs read even higher again).

Ask anyone that works on diesels (lots of them use mainline dynos)

Also, a 300kw Gen III commodore makes 180-190 rwkw...they make over 200 on Dyno Dynamics.

One interesting thing is that the torque reading that the dynologs give is surprisingly accurate. A mate of mine has put his GT2 and GT3 on his dyno and the torque reading was almost exactly what Porsche quote. It was a similar story with his Galardo too.

Out of interest Paul, how much torque did the GTR make at autosalson?

But in the end...who cares, the dyno is only a tuning tool...Buster has the right idea.

Something very perculiar is happening if the GTR made the same power in AWD as it did in 2wd...it is physically impossible!!

I work with and do alot of tuning on a Dynolog dyno, and can verify that it is quite common to see 15%+ going from ours to a Dyno Dynamics dyno in shootout mode. Its the norm to add at a min 10% to our results to compare with others on DD dynos... but 15% is more common.

The Dyno log dyno's are a nice bit of gear, with the oil temp loggers, air temp, 3 map sensors, 8 egt sensors, and the fuel flow meters. you can diagnose most problems presented to you.

Its quite common to see quite large figures quoted in the magazine's, and one cant help but be impressed, however when you see the MPH, if posted, its usually alot lower than expected, an indicitave of not such an impressive number. At least relative to what im used to seeing on a dynolog dyno.

Anyway, in summary of my ramble, for you guys who use dynologs, add about 15% to your value and your in ballpark dyno dynamics teritory.

[ronald_r32]

just out of interest, how much does a dyno cost all up to buy?

[paulr33]

around 80k i would imagine

[Fastrotor]

all depends on what options you add to it, but your looking at $200k + for a 4wd dynolog with options as above .... now you know why it costs so much !! alot of dollars to re coup !
