500HP EFI Stage 1 Blue 99-05

Year: 99-05 Stock HP: 500 I/C: EFI Stage 1 Finish: Blue

STAGE 1 This is a similar package that many OEM engine builders use for their engine packages. This utilizes the new W200ax (3.3 liter) compressor and larger intercooler. Plenty of potential for later modifications.

Want big top end speed, dramatically improved cruising speeds and ability to plane faster? How about not having to sacrifice reliability, durability and idle? What about ultimate bragging rights to owning one of the most incredible looking and technologically advanced marine engines? Sound to good to be true? Well its not, Whipple has the supercharger system for you. The Whipple 500 HP EFI SC System will give you all the torque and horsepower your heart desires. With 6lbs. of intercooled boost, your power will increase nearly 50%! Skeptics say, “what about idle?” That’s simple, the Whipple twin-screw type supercharger and ECU calibration will allow for your engine to idle consistently, in and out of gear for easy operation.

The looks are only part of the package, the performance will put an ear-to-ear grin on your face. Because of the unique twin-screw SC design, the Whipple Charger can generate full boost at any rpm, just the touch of the throttle and you have instant power. Roll into the throttles and feel the g-forces push you back in your seat while the sound of an F-16 fighter jet comes too life. You’ll turn your once docile boat into a pure adrenaline rush while putting other boats in their place when they “attempt” to run by you.

the 500 HP EFI SC System comes with a large integrated cupronickel intercooler that fits inside the intake manifold.
