You need only drill one hole in the fan shroud, slide a clip in, and bolt down the intercooler reservoir. Before you do so, you'd be wise to install the intercooling systems coolant hoses. They fit perfectly and include factory-style clamps, and even protective sleeves.

Like the heat exchanger, the bridge that mounts the intercooler pump attaches using extant hardware for the bumper beam NVH isolator. As you can see, the kit even includes new radiator side shields for both sides. The left side includes the ducting for the air box inlet and a path for the intercooler hose. All the parts look like they belong, as you'd expect from an FRPP kit.

Since you are relocating evaporative emission canister purge and the throttle body, there are wiring harnesses that must be extended to make the connection. Pay close attention to the FRPP instructions, as the wiring is critical to making this system function properly. Not only do you have to relocate some pins on the stock harness, add a new connector, and lengthen the harnesses for the throttle body and EECP Valve, you also have to tap into the radio harness for switched power and add a whole new harness for the intercooler pump. If you aren't fully confident with wiring, you'll want to choose a pro install shop.

While the kit retains the stock lower airbox, it includes a new lid/mass air housing replete with hydrocarbon absorption mat, which is one reason the FRPP kit retains emissions legality. Here Jesse swaps in the factory mass air electronics into the new airbox lid. Naturally, there's a new clean air tube that joins this lid to the new twin-bore throttle body, which is a stock-spec GT500 unit.

Whipple superchargers are shipped dry, so they are clearly labeled as such. You must add oil to the blower's gear case before you operate the blower. There is a fill window on the front of the case that let's you know when you've added enough oil.

Looking the part of a factory option is the completed FRPP/Whipple installation. All that's left to do is install FRPP's new calibration and hit the road-or in our case, the dyno.

After having the blower installed at Power By The Hour in Boynton Beach, Florida, we headed down to STP Motorsports in Plantation, Florida, to spin the car on the Dynojet rollers.

This graph certainly tells a happy tale. The FRPP/Whipple kit picks up the horsepower and torque curves and sits on a higher, happier plane.
Things don't always go laboratory smooth for us. We were on the cutting edge of the FRPP/Whipple kit and ended up starting out with a preliminary ProCal tune with an aggressive knock sensor profile. With this first program and Magnaflow mufflers as the only other mod, the car made 505 at the tire. However, FRPP wanted us to try its final calibration for the story. Naturally, Lethal had already started modding the car, and had reinstalled its off-road X-shape crossover, so there is more than one change going from baseline to the final 525-rwhp number. Still it gives a good idea of the capabilities of this kit, which added triple-digit gains from 5,300 rpm on.
