i dyno'ed on 2 dyno jets.

#1 in vegas, dyno'ed 511/570 , 10psi turbo w/ Salt Lake City tune where i live at.

#2 in utah, dyno'ed 430/530 , 5psi , same tune...



i'm guessing the lower dyno # is because the #2dyno didn't have the brake on for some rolling resistance not allowing the turbo to spool ?

or the 5 psi difference?

i suspect it only spooled to 5psi because there wasn't enough of a load on the motor/turbo due to the drum spinning pretty much freely

Could you post the dyno sheet? That will help evaluate things.

I tried a Dynojet once, and my 9 psi tune barely boosted on the dyno. I kept cranking the boost controller until I got almost 10, then had to imediately turn it down when it tried to spike to 16 on the way home. Dynos are tools, and must be viewed as such. The wrong tool for the wrong job=the wrong result.

Mine had to be locked up on the dyno to see any kind of boost, supercharger though, even with that, it saw a couple more PSI on the track.

Which shop was the dyno in Vegas - Have heard of a couple places in town dynoing high - then dynoing lower at other locations.

can you post the files, and are they DRF or DLF files? If DRF then no load was used (either, old 248 or non load control 224 dyno's) For a turbo car, you need to use load, and ideally the eddycurrent load, not the brakes.
