Good numbers! Fwiw I only gained a whopping 1HP and 7TQ from Mustang to Dyno back when I was cam only and even added an SLP -25% crank pulley between the 2 dyno sessions.
382/354 on the Mustang
383/361 on a Dynojet + SLP pulley
449 is good for your mods no matter what dyno it is on an LQ4

And in a lot of cases, no.
Seen this happen quite a few times also.
I would say you should hit ~470 on a dynojet.

Agreed, 450/420 is dang good with an LQ4 through a 12bolt. 500whp would getting into 402/408ci territory with that top end and mild compression

Well its not impossible. I have seen quite a few 6.0L LS2, LQ9 motors do 500whp on dynojets. They had trickflow or Ai heads and mild cams.....there are a few even in this post. Don't need a 402/408 to do that.

It really doesn't matter to me what it makes on a dynojet, its really just to cure my curiosity. I know she is a hole different animal for 333 hp car she was. Im ready to do gear change soon cuz she really dont start coming on till bout 3500rpm.
