In addition to the 11-pound pulley that came with the kit, we had ATI include a smaller 14-pound pulley-hey, why not? Although a lower-mileage engine would have no problem supporting such boost, we're going to hold onto ours for a while, as we want to get some track time under our belt before we go for broke.
Speaking of the track, we had hoped to bring you some results, but unfortunately the 1320 is covered by 12 inches of snow at the current time, so you'll just have to tune-in later for elapsed times. Our '90 GT is also getting some huge Cobra brakes courtesy of Ford Racing Performance Parts and a trick set of wheels from Discount Tire, so keep your eyes peeled as this pony is blown, stock, and born to rock.
 Mounting the ignition so far...  Mounting the ignition so far away required lengthening some of the wires. Take care in this part of the install, as you don't want to be hasty. |  The battery tray is relocated...  The battery tray is relocated to the passenger side with a supplied power cable. The negative cable just needs to be swung over from the other side. The car's rather large battery made things a bit cramped in there, but it all fit in the end. |  In this photo is the Pro-M...  In this photo is the Pro-M mass air meter from Brothers Performance Warehouse. Also shown is the supplied washer fluid pump, which Dan mounted on the shock tower. Wires were then spliced into the factory harness for seamless operation. |
 Our ProCharger install is...  Our ProCharger install is complete and here we are at La Rocca's Performance in Old Bridge, NJ. Using a Dynojet dynamometer, La Rocca tuned our pony to perfection. We had been here prior to the installation so we would have power numbers from before and after on the same dyno. |  In order to burn a custom...  In order to burn a custom computer chip, the factory one needed to be removed. This entailed taking the computer out of the passenger's kick panel and removing the ECM. |  Here, Jimmy Chahalis cleans...  Here, Jimmy Chahalis cleans the contacts. This is essential as bad connections can cause the car to be ill-mannered or not even run at all. |
 Working magic under the hood,...  Working magic under the hood, Jimmy La Rocca and Andrew Barrale made several dyno pulls and part throttle runs to fine-tune the program. |  While it appears they are...  While it appears they are looking at a blank screen, they are indeed viewing tables and charts that can be adjusted for optimum performance. Not only did the chip improve power numbers, but it made a vast difference in the drivability of the Mustang. It was now more crisp and responsive than ever before. To the left of the laptop is the burner with the chip sticking up from the end of it. |  Dynamometers don't lie and...  Dynamometers don't lie and we were extremely pleased with the results. With 333hp and 389 lbs-ft of torque at the rear wheels, our '90 GT has been transformed into a Camaro-smashing Firebird-bashing hulk. |
