1998 Ford Mustang Cobra - 190 & Counting
Is This The World's Fastest Mustang Cobra Street Car?
The stock intake, modified by Paul's High Performance, takes air from a Ford Racing throttle body and a Pro-M mass-air meter. There's also an MSD DIS-4 ignition box, along with an MSD crank trigger. The fuel system includes 50 lb/hr injectors, Steeda fuel rails, an Aeromotive fuel pump, and a 22-gallon Fuel Safe fuel cell with a custom pickup that keeps the engine happy with a steady diet of 100-octane Unocal pump gas.
Getting just 4.6 liters of displacement to make more than 2 hp per cubic inch takes some serious boost, ably accomplished by a Vortech T-trim supercharger with a Sean Hyland air-to-air intercooler. Also in place is an AFM Power Pipe and a Sean Hyland eight-rib pulley system for the blower and front engine dress. In the car's current tune, the blower's peak boost is 16 psi, a point where the 4.6 is making well above 600 hp at the flywheel. Tuned by Race Systems using an Autologic chip, the car makes impressive power on a Dynojet: 575 hp at 6,800 rpm and 455 lb-ft of torque at 5,600 rpm at the wheels running an off-road X-pipe. At speed going down course, tuner Byron Reynolds surmises the intercooler adds another 30 hp.
So, what's it all worth? At the September 2003 Silver State Classic, Tim was on a 177-mph average at about the 60-mile mark on a 90-mile course when a tire failure sidelined the car. At other events, radar has measured a solid 190-mph high trap speed. Tim says, "I want to have the first stock-bodied Mustang street car go 200 mph. Open road racing is the most fun I've ever had with this car and, if tire technology allows, I might someday see 200."
For now, 190 is certainly fast enough for us.
