Well as some of you may or may not know, I have been driving my car un-dynoed at about 14psi. This is on a Totally stock zetec from intake manifold to exhaust gasket outfitted with the Top Speed Street turbo kit with GT3076r. Well I finally got around to throwing it on the dyno and it made about 280whp. So we decided to go for broke and turn it up! At 15psi It made 293whp & 291wtq. Then we wanted to go after the CLAIMED record at 320whp so a few lbs of boost later we ended up with 325whp and 320wtq!
And now comes the chart.
The dark red run was 15psi.
The blue run was 18psi but cut short by me not raising the boost cut on my EBC.
The red run was on the same boost as the blue just to confirm any doubts!
All runs were made on a Dyno Jet 224x and on 93 octane!
Updated Chart with 2K IM and 18.5-18.7 psi still stock longblock and 93 octane! Clutch was slipping.
