ProCharger's P-1SC self-contained centrifugal supercharger lies at the heart of the '11 Mustang GT HO Intercooled system. Once Blow-By Racing's '11 Mustang GT was strapped to the dyno, we tested with a 4.38-inch pulley, which produced 7 psi of boost; then a smaller 4.25-inch pulley, which was good for 7.5 psi.
Once the newest rendition of the 5.0-liter was released, Mustang enthusiasts were thrilled to finally see factory horsepower numbers high enough to put a hurting on just about anything from brand X. As the engine specs began to surface, the question also arose about how the new powerplant would respond-and more importantly, survive-under boost. Accessible Technologies (ATI) ProCharger is ready to put all doubts to rest with its HO Intercooled and HO Intercooled Tuner supercharger systems for the '11 GT.
ProCharger has long been known for its powerful supercharger systems, and when talk about its new kit began to spread around the Internet, we decided to investigate. With the stock compression ratio at 11:1, the Mustang GT doesn't seem so boost-friendly. But Jeff Lacina, marketing director for ATI ProCharger, explained how ProCharger can offer significant power gains without compromising the 5.0-liter's reliability.
"ProCharger used its years of experience with high-compression engines when the '11 Mustang GT HO Intercooled system was designed," explains Lacina. "With higher static compression ratios, boost levels need to be lower to control cylinder pressure. Beyond that, supercharger and air inlet temperatures (AIT) need to be closely monitored. The cooler the inlet temperatures, the better the engine will perform."
He adds, "When we designed these systems, we really looked at all of the components Ford used in the base engine. The materials used for the rods, pistons, and crankshafts, as well as the fact that the 5.0-liter is designed to run well on 87-octane fuel, gave us a good idea of what we had to work with. The HO Intercooled systems are designed to make great power on 91-octane fuel."

ProCharger utilizes an efficient air-to-air intercooler to keep the air inlet temperatures under control.
At the heart of the HO Intercooled systems is the P-1SC centrifugal supercharger. With a dedicated eight-rib drive system and a one-piece mounting bracket, which incorporates an idler pulley and belt tensioner, installation is very straightforward.
Checking in at only 7 psi, the system is advertised to increase horsepower by as much as 165 ponies. Add a highly efficient air-to-air intercooler, and you have a system capwable of huge horsepower gains in an easy-to-install package. To make things even simpler, ProCharger includes a preloaded SCT handheld programmer with the HO Intercooled system.
"We designed these systems to be installed very easily," adds Lacina. "One of the best parts is that it doesn't require any cutting or relocation of anything under the hood."

ProCharger has named this intercooler the MAFtercooler, due to the location of the MAF sensor near the outlet. The sensor was moved to this location because it offered the straightest airflow throughout the system, which delivers the most consistent readings.

The stock MAF sensor is removed from the factory cold-air intake and mounted in the intercooler. ProCharger supplies an extension for the mass air harness, which is used depending on how the wiring is routed.

Nick Schmidt, (left) calibration engineer for ProCharger, came to Blow-By Racing to take care of the installation of ProCharger's newest supercharger system. With the help of Chris Jones, the front bumper of BBR's '11 Mustang was removed to make room for the system to be installed.
Wanting to get a closer look, we headed to Blow-By Racing (BBR) in Boca Raton, Florida, where Jeff Lacina and Nick Schmidt were making preparations to install the kit on BBR's '11 test mule. Follow along as we take a look at the install and subsequent dyno test from ProCharger's '11 Mustang GT HO Intercooled supercharger system.

ProCharger uses a dedicated drive system to turn the supercharger. An eight-rib belt spins the blower separate from the rest of the accessories. This is a huge benefit if there is ever a belt failure because the charging and cooling systems won't be affected.

Next, Schmidt bolts up the supercharger bracket. Four bolts from the engine cover are removed and replaced with longer bolts and spacers to accommodate the bracket. This bracket also holds the belt tensioner for the blower belt.
