Dyno day next weekend!

That's right in line with most of the turbo'ed IDI numbers from the dyno event at the Rally. If that dyno couldn't load an IDI, how in the world could they get accurate numbers for big HP trucks? What dyno was used? Were they using SAE, STP, or Dynojet HP?

My friend has the same garrett/ATS turbo I do with the 3" down pipe and wastegate disabled. He's running a tube with an open filter while I still have the airbox with a tube running down by the radiator. Just like me he was only able to hit 6psi on the dyno while getting more on the street.

I'm not entirely sure about the dyno. I saw Dynojet all over the equipment and the printout says "WinPEP Dynojet" The measurements appear to be in SAE.

That's very strange. I saw 12 psi on the dyno with the DPS injectors. With the Moose injectors, the 15 psi gauge was pegged beyond 2500 RPM. I never see that kind of boost on the street. I have to wonder what's up with their dyno. I don't know much about dyno, but from what Dennis Perry told me (owner of TS Performance) during my conversations with him, Dynojet is the least accurate dyno manufacturer. If it is not able to place a decent load on the engine, I can see why.

Like I said, I'm no expert, just repeating what I was told.
