We’ve done Mustangs with Prochargers before, but this one is a little different. The owner brought us the car with the Procharger already installed and wanted to do a little twist on it. He wanted an smaller diameter pulley for more boost, but a waste gate on the intercooler piping to regulate boost pressure, and allow for a better torque and turning a procharger into a TORQUE MONSTER. With this kind of setup he will be able to run different amounts of boost up to the max psi that the pulley produces.
Placement of the red Tial blow off valve and wastegate was definitely important. From the outside others had to know that this Mustang was something special. We decided to mount them on each side of the intercooler so that they’d show in the lower part of the front bumper. Their red color definitely makes their presence known.
The small diameter pulley can produce about 20 psi of boost, but the wastegate will be able to regulate it. The Tial BOV is located under the MAF on the left side of intercooler, which Would cause distorted readings. To solve this, we relocated the MAF to the cold-side intercooler pipe. we also added a PMAS Hpx Frequency Maf to allow the proper scaling for this setup This smoothed out readings and allowed us to get accurate data while tuning.
While we were under the hood, we upgraded the crank sprocket and oil pump gear as preventative maintenance, since they are known to fail. Once all of the fabrication was done, it was pulled onto our Dynojet for some tuning.
After some work on the Dyno this thing laid down an Impressive 702whp and 575wtq at 13 pounds of boost. The tune was Done through Hp Tuners. The blue lines are from the previous tune with the procharger before the smaller pulley and other modifications we did this time around. It’s definitely a substantial increase in power
