Check out the article in the Jan 2011 issue of 5.0 Mustang & Super Ford
magazine, pgs: 58-64. (not online yet), but it should be in your mailbox or on newstands this week. On page 62 is their "On the Dyno" chart for this install.
Keep in mind, this installation was on an automatic-equipped 2011 5.0. At 6,400 rpm (where they ran the naturally-aspirated car to) added 138 rwhp and 101 lb/ft of torque. Running the ProCharged car up to 7,300 RPM (where this dealer elects to shift at), recorded 517 rwhp at 7.4 psi of boost.
Note: this was a straight-out-of-the-box installation and tune. Suffice it to say, there is LOTS of room for additional HP gains with a custom tune. Trust me: the guys at Evolution Performance are ALL over 5.0 performance... as several other ProCharger dealers across the U.S. and Canada.
Stay tuned for more testing with the new Stage II System that was introduced at SEMA.
The December 2010 issue of Muscle Mustangs & Fast Fords
also has an install/dyno test article...this one on a manual trans
car... pgs: 94-104... The P-1SC-1 went up to 543 rwhp and 429 lb-ft of tq... and a D-1SC (that dealer Blow-By Racing had on hand) took it a stock 2011 5.0 4V up to 607.53 rwhp, 491.72 tq... oh yeah, it was also 95 degrees and 65% humidity in the shop that day...
