A New Edge Two-Valve isn’t going to intimidate most Mustang enthusiasts. The Two-Valve engine just doesn’t make that much power in most configurations, especially stock. If anyone knows this, it’s TJ Lapinski. His 2004 GT at one time had a built Two-Valve, “It made about 470 horsepower at the wheels,” he says. Of course, he wanted more. Revolution Automotive suggested a Coyote swap, so that’s the direction he went. With a JLT Performance cold air, BBK Performance swap headers, a return-style fuel system, and a built 3650 transmission, the car made 430 horsepower and 409 lb-ft of torque at the wheels. With a 4.56 gear out back, the GT ran 11.0s, and he ran the car in that trim for a year.

Next up was a Cobra Jet intake with a Revolution Automotive cold air, 4.88 gears, and a Tremec TKO transmission. With those changes the car responded with a 10.7 at 128 mph. To the mix he added a Paxton supercharger. “I couldn’t pass up the deal on the Paxton,” TJ says. Now TJ did the Coyote swap before they were commonplace. Therefore, a lot of work had to go into installing the Paxton, but Revolution Automotive was able to make it happen. With the Paxton, the GT made 690 horsepower on pump gas, and 721 horsepower on VP Racing C16, both at the rear wheels, obviously. The best time in that configuration was a 10.2 at 140 mph. TJ didn’t really have a lot of time with the car in that trim because of drivetrain reliability issues.

With a Rich Groh Racing (RGR) short-block in the car, a Boss intake, and a JPC Racing single turbo kit on the car, the New Edge is now capable of striking fear in the eyes of competitors.

For 2016, TJ really switched up a few things on the car. With JPC Racing now turning wrenches on the car, out came the factory Coyote crate engine, and in went a RGR-built short-block with factory heads, and a Boss intake and valvesprings. For a power adder, JPC added one of their single turbo systems utilizing a BorgWarner 76mm turbocharger. To put a transmission in the car capable of handling the new power, TJ turned to Wayne Bryant at Bowie Transmissions for a Turbo 400 with a reverse manual valvebody, a Transmission Specialties converter, and a 4-inch aluminum driveshaft.

TJ put it all together at JPC’s Track Day at Capitol Raceway in Crofton, Maryland August 28th, running 8.64 at 150 mph with a 1.2 short-time during his first pass. TJ had big hopes going into the ModNationals, however, he says the air was better at Memphis, so he thinks the combination was making more power and blowing through the converter. We’re sure that issue will be remedied before TJ’s next trip to the track.

This is the latest photo of TJ’s 2004 Mustang GT. As you can see, the transmission is already out, getting ready for a revised torque converter.
