C&L INTAKE PLENUM FOR 2V 4.6L MUSTANGS


VI. DYNO TEST - VEHICLE 3

Dan Hourigan is the sales and technical support manager for Dynojet, the world's most popular chassis dyno manufacturer. When he found out about our new plenum, he contacted us to see if he could try one on his personal supercharged 2000 model GT Mustang. Knowing that blower cars just love airflow enhancements, we sent him one of our first units for some independent testing. The details on his car and his testing procedures are as follows...

2000 GT
10# P1sc S/C kit with a 3 core intercooler
42# injectors
Euro Focus pump (returnless friendly and flows 260+ lph)
Lightning 90mm MAF
Bassani cat-back

The testing was done with an average of 10 minutes passing between each run. This was to allow the temperatures to stabilize to maintain as much consistency as possible. Each run started with 176 degrees (ECT) showing on the scan tool, and timing was LOCKED at 14 degrees in the chip as not to skew the results. The dyno scans (below) tell the whole story. Depending on the RPM, the new plenum and 75mm BBK throttle body added anywhere between 15-20 rear wheel horsepower, and an equal amount of torque. Definitely a nice, solid improvement over the factory plenum.

In order to show that these performance gains were not resulting from an adjustment in the Air/Fuel ratio on this vehicle, we have enclosed an air/fuel ratio chart from these dyno pulls. This shows that even on a supercharged vehicle, it is not necessary to re-tune your computer to take advantage of the benefits of our new plenum.
