That pulley looks a little small to be the standard 9psi one. Got a measurement?KB 1.7 9 PSI, intercooled, O/R x pipe, everything else stock.....................
KB GT 1.7 9psi dyno video- Video
...while we're at it, I'm spotting an upgraded throttle body, Big Tube inlet and CAI intake kit on there right off the bat. And those are only the things I "can" see in the quick underhood video....what else has he (you) neglected to mention in the parts breakdown of the set up.
Also, assuming that's a real Roush? If so, iit's got an upgraded cat back over the standard GT as well. So...I wouldn't say it's stock in comparison to a standard GT.
Strip off all of that extra stuff and put a stock GT exhaust on there for me and see what kind of numbers you come up with.
Come to think of it....haven't we argued about this before? I don't think you answered me then either?
