Whipple, known for its industry leading supercharger systems and committiment to leading the market in power has now brought that same technology to the 2.3L Mustang Ecoboost with the massive Monster Cooler. The Whipple Monster Cooler offers nearly 3 times the surface area of the stock unit offering unsurpassed cooling capacity and consistent power. The Stage 1 system includes a SCT X4 flash tool and a custom calibration to unlock the leftover power in your Ecoboost Mustang. The Whipple Stage 1 system is the first and only 50-state legal Ecoboost upgrade package available today, allowing for upgrades in all 50-states.The factory intercooler cannot keep up during consistent power demand, easily exceeding 200deg F after the intercooler with stock tuning. That's 200deg F air going into the motor, robbing power, reducing spark advance and requiring extra fuel to keep the powertrain live. With the Whipple Mega Cooler, temps hover nearly 100deg F cooler then stock giving more horsepower and torque then stock, without ever changing the calibration or other bolt on parts. Even better, the temp maintains consistent run after run where the stock one continues to rise.
