The blower bracket mounts to the front engine cover on the passengerside. Four bolts are removed from the cover and the bracket getsinstalled. ProCharger supplies longer bolts to fasten the bracket to thefront engine cover.
ProChargerintegrated the MAF sensor in the blower tubing so it acts as ablow-through setup now. "We tested a couple different ways [of runningthe MAF sensor]," says Jones, "and this was the best. Being that it is aFord meter, you get a great and consistent signal." The factory MAFsensor is removed from the stock airbox and gets installed in the blowertube.
The standard blower unit is a P1SC-1 and was introduced to themarket several years ago. It features a self-contained oiling sys-temand does not require tapping into the engine's oil system or oil pan.The P1SC-1 was selected because of the engine's 300hp naturallyaspirated rating. ProCharger uses an engine's base horsepower rating todetermine which head unit will be used for that application. The P1SC-1taps out at 825 hp and can produce upward of 32 psi of boost on properlyprepared engines. Run-ning just 9 pounds of boost is no sweat for thisblower.

The MAF sensor is relocated to one of the blower tubes, and is shownhere screwed into place. Removing the factor sensor from the air box isas simple as unplugging it, removing two screws, and gently lifting outthe sensor.
By now everyone knows of the '05 Mustang's computercomplications. It leaves a lot to be desired when the driver demands themost performance from his/her Mustang. The drive-by-wire technologyeliminates the throttle cable, and an electric motor controls thethrottle blade on the throttle body. The electric motor receivescommands from the computer, which senses the gas pedal position. Fordhas restricted our fun by programming commands in the computer system topull the throttle blade back a bit when the gas pedal is slammed downtoo aggressively; it also restricts the fun when you try to powershiftby backing down the herd.
Another aspect to this new computer system isa torque load sensor. Essentially, when the power is increased, theengine senses it and pulls back the reins--effectively negating thegains from the aftermarket parts. From our understanding, just adding anexhaust system will not be a problem, but when you start increasingairflow into the engine, the computer takes over and negates the powerincrease. The computer goes into a limp mode. Thank- fully, you will nothave to deal with that due to the many aftermarket computer-tuningcompanies out there.

A P1SC-1--which has had an impressive life thus far in the Mustangworld--is included in the kit. This head unit is capable of producing upto 825 hp and 32 psi of boost on properly prepared engines. In thisapplication, the pulley arrangement allows for a maximum boost level of9 psi. That equates to 441.8 hp and 409.8 lb-ft of torque at the tires.Testing in stock trim yielded a peak of 266 rwhp.
The DiabloSport software (which is included in theProCharger kit) has the capabilities to overcome these obstacles and getthe new car's computer tuned properly. Scott Beer, one of DiabloSport'stop tuners, was present for the test to ensure every- thing wentsmoothly. He used one of the company's Predator tuner tools to upload asupercharged-oriented program.
That ProCharger includes Predator tuningtools in the kits makes this a truly turnkey setup. DiabloSport hasadded a special ProCharger '05 Mustang section, which includes apreprogrammed tune-up. That way a customer needs to only use thePredator to reflash the computer during the blower installation. If moremodifications are made to your '05 Mustang, the Predator can modify theexisting program or upload a new one from DiabloSport.
So what is it allworth? Freedman's '05 pounded out 441.8 wheel horsepower and a maximumtorque reading of 409.8 lb-ft. The boost gauge touched 9 psi at the topof the pull when the engine was singing at 6,200 rpm. This was anincrease of 175 rear-wheel peak horsepower (this hot rod produced 266 hpin bone-stock trim). Freedman's Mustang even had a completely stockexhaust system. We're willing to bet the power levels would have shot upeven higher with aftermarket exhaust.

To help clear the blower and its pulleys, the radiator overflow tank hasbeen relocated. It now sits on top of the radiator.
Horsepower numbers are only halfthe story as we hit the streets with the newly supercharged Stang. Ourtest was conducted during the winter, so we were not able to flog thething on the dragstrip. Bringing it out on the public roadways gave us aclue as to how this car will run. Despite a sand-and-salt mix coveringthe roads, we laid into the throttle rather aggressively. Immediately,the first thought was, Wow. Like a typical centrifugal blower, the powerkeeps climbing until redline. But there was gobs of torque down low,too. It planted us in the seat, and conservative estimates put the '05somewhere in the mid 11s with good tires.
As your senses overcome theacceleration feeling, the next thing to pop into your mind is, Where'sthe blower noise? The regular blower whine is noticeable from theoutside, but the interior was dead quiet--even when whaling on the loudpedal. We can't wait to start turning up the boost and adding some moregoodies.
The future of '05 Mustang performance is bright.
