All this talk of different Dyno's, and prove it on the track etc, really amuses me.
The thread title is........... 319wrhp Standard Turbo! (maybe).
You cannot prove any of this without dismantling the turbo. FULL STOP.
And any of you other guys with "freaks" should think about this.
I know my Turbo was "hi-flowed", as I had it done when I killed it (as stock) with too much boost.
I wonder how much anyone else knows how stock their turbo is ?
Will continue to watch this space with amusement.
