This dyno chart is the second dyno session by Stangpro with adding our Tunable Induction 96-04 full GT system to the same 03 GT in the above dyno graph. (Both of these dyno sessions were conducted with the stock factory meter)


This session netted 230 rwhp, 271 rwtq after adding our #5 full GT system.

Our system resulted in a 13 hp gain.

These two dyno sessions were performed on the same dyno but on different days as can be seen on the dates on the dyno charts.

Expect to gain 10-13 rwhp with our 96-04 GT system.

The unusually high torque gains in the second dyno session were verified correct but we feel approximately 10 ft. lbs. of torque to be the normal gains with our GT system.

Our Stage 3 systems include the Dragon 75 TB / Plenum / CAI. Expect gains of +20 - +24 rwhp with the complete Stage 3 Package. This 03 GT in these test sessions went from 206 rwhp (stock) to 230 rwhp with the addition of the Stage 3 components.

This is a recent independent customer dyno session comparing the
# 9 03/04 Cobra system to the Steeda 03/04 Cobra system. 
The # 9 system gained + 17 rwhp over the Steeda system.
 

Bullitt With Drop In Filter

Same Bullitt with the addition of the # 4 meter forward system
7.8 rwhp & 9.3 ft. lb. torque GAINS!!

This is How our 3.8 #3D System Performs

Before and after Dynoruns of a 3.8 adding a Full Length #3D System


Before run: 3.8 v6 with stock air system, 98*F temp in dyno room
After run: 3.8 v6 with Full Length System, 98*F temp in dyno room
That's 12.5 RWHP and 14.8ftlbs of torque! This is an independent test.

Before and after Dyno runs of a Modular 4.6 GT

Our G.T. T B. Pipe is Good for +4.3 RWHP & +5.5 RWT
 

This is a dyno session by MotorTech Mag comparing our #1 89-93 full 5.0 with the stock factory system and meter


Pictured above, our system is denoted in red while the stock is depicted in blue. Our 5.0 system shows a 10.8 rwhp, 4 ft.lb. rwtq. increase.(down filter position, up position not tested)

The dyno testing results of our 03-04 Cobra system in the UTI Shootout demonstrates how the tunablity of our system affects horsepower and torque.

This is the same 5.0 Magazine stock 03 Cobra shootout winning system.




The system made more power in the down position, which can be argued as far as accuracy for two reasons, the first being the air closer to the floor in the dyno cell was colder and secondly, the car had always made less power on second dyno pulls all day. In the “up” position the car made 371.05 HP and 365.12 lb/ft of torque. This is an improvement of 19.68 HP and a gain of 5.83 lb/ft of TQ. In the “down” position, the car tested at 376.85 HP & 372.24 lb/ft of TQ. This is a gain of 25.48 HP and 12.58 lb/ft of TQ. Air fuel ratio stayed safe and below 12.5 for the entire run after the PCM went into WOT strategy.

The tunable aspect of our systems will elicit changes in horsepower and torque for each application. The gains will vary for blower and naturally aspirated motors. The two-bend filter positioning will not adversely affect meter calibration or A/F ratios.
