2011 Mustang GT Whipple Blower Test Part Two - Pump Up The Volume

Installing the Whipple CAI is a bolt-on affair. Simply swap the stock mass air electronics into the 123mm housing, clamp on the tube, install the factory connections, and you are good to go.

On look at L&M's larger, smoother twin 66mm throttle body (PN LM-GT500TB; $540) for GT500s, and you can easily see it flows better than the stock GT500 throttle body used in the FRPP/Whipple kit. L&M says this throttle body is good for quadruple-digit airflow and horsepower.

Installing the L&M does require that you swap over the factory throttle-position sensor, spring, and electric motor. Once these parts are installed, the throttle body is an easy, bolt-on affair.

Of course after trying just the CAI, the Lethal crew had to swap out the throttle body and reinstall the CAI.

Combined with Jon Lund's tuning expertise, the improved induction and throttle body really woke up the FRPP/Whipple kit with big gains at the wheels.

This graph shows the sweet results of successful mods. Each bolt-on added a significant chunk of horsepower across the power band.

With each crop of mods, Lethal Performance's Jared Rosen heads over to STP Motorsports in Plantation, Florida, to run the '11 on a Dynojet.

Back at Power By The Hour mere weeks after installing the supercharger kit, Jesse Guajardo removes the 2.3-liter blower in favor of its 2.9-liter big brother.

Unlike its smaller brother, the Whipple 2.9 is not set up to seal with an O-ring. As such, Jesse applies sealant to the FRPP lower manifold. After letting it setup just a bit, Jesse dropped on the new blower, bolted it up, and reinstalled the same induction and throttle body that were on the 2.3-liter blower.

All Whipple supercharger are shipped dry, so don't forget to add the supplied oil until it shows full on the fill window on the front of the blower case.

Though the new setup doesn't look quite as OEM with the huge induction, the Whipple 2.9 looks right at home atop the Coyote 5.0.

Since bigger boost and more power is in the offing, Lethal also opted to have Power By The Hour install one of Afco's dual-fan heat exchangers (PN AFC80280PRO; $669.95). As we've seen on upgraded GT500's, these heat exchangers can lower and stabilize inlet temperatures, thus staving off power-robbing heat soak.
