Been out a while..wow. Many of you are probably wondering why but last July, my dad was killed in a head on colision in his work truck
As many of you know, Him and I custom fabbed my 04 GTs twin turbo kit and its just been my pride and joy.
Last time the car made 550RWHP @ 11.9PSI...all it would get on the dyno. That was with full exhaust.
Well that came off and just a few months back I decided to rebuild the downpipes with 3 inch and exit them right behind the FRONT tires. That was the only change minus my updating the tune and some 80#/hr injectors.
Without further delay...
9.3PSI run
12.6PSI or so peak.
and the last one it peaked @ 14.5PSI then dropped to 13.5 as I didnt have the boost setpoint ajusted correctly.
Oh and the combined runs.
Did I mention that this was all done on a STOCK SHORTBLOCK/STOCK HEADS, 4.6L 2V?
I have videos of the runs and pictures of the exhaust if anyone is intersted. Also please do not pay attention to the A/F...its off. My wideband reads 11.0-11.3 on the topend...I have it stair stepping down as boost rises.
