50 Engine Bolt Ons Hp Performance Turbo Kit
HP Performance Turbo Kit: 622 hp at 5,800 rpm, 637 lb-ft at 4,700 rpm
The final modification applied to the 5.0L was a single-turbo kit from HP Performance in Roswell, New Mexico. The kit featured a 67mm turbo, an air-to-air intercooler, and 44mm wastegate. All of the exhaust tubing featured Jet Hot-coated to maximize heat energy to the turbo, while the intercooler was sized for maximum heat rejection. Look for this kit combined with a larger turbo on a 400-plus-inch stroker in the near future, but we have successfully run the system at over 1,000 hp, so it was more than sufficient for our mildly modified 302. Use of the nitrous and turbo kit is why we installed the forged crank, rods and pistons. The kit taxed the 36-lb/hr injectors on this application, so we manually raised the fuel pressure on the boost-referenced regulator to 60 psi (from 43 psi in NA trim). This provided plenty of fuel to keep the air/fuel mixture safely at 11.5:1. View Related Article
