I am, like everyone else, loking for a little more power. The problem is I have a 496 HO and I have heard two different things about this engine. I like it as it is now and have put 110 hrs on it but it is time to go faster. I am just looking for a little input from anyone that has done one or feels he knows something about them. I am on a bit of a budget. I could swing the blower but I have a plain bravo 1 and wonder if it is up to the task. Sorry so long and thanks for your help.

I too am waiting for someone else to be the guinae pig.
Did you see the test in power boat comparing the whipple
and procharger on the 496? Crockett is also working on
something. Just waiting for the right thing to do. Not
willing to give up my boating season for speed. Still wondering
about reliability issues.
As for the drive, if you dont hammer it off the line I would think it would survive. I went with the xz planning on future upgrades.
Does any one have a blower on their 496? hours? problems?
thanks, John

We are in the process of putting ProChargers on a boat with 2x 496 HO's.Boat currently runs 75 mph.We won't start on it till next week.

I tell ya what. Everyone pitch in a few bucks and I'll be the guinea pig. How's that for a deal?...

Now there is an offer we can't refuse.
I am just worried about reliability of the engine and drive. I even wondered about swaping out the 496 for a 500 EFI then at least I would not worry about the engine.
Damn this horsepower flu.

Whipple’s Superior Performance:
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 too good to be true? Well its not, Whipple has the supercharger system for you. The Whipple 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?” With a modest 5-6lbs. of boost, your stock power will increase nearly 50%!

The looks and OEM like idling 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 addreneline rush while putting other boats in their place when they “try” to run by you.

Skeptics say, “Well you can’t have low end torque and top-end horsepower!” Yet again, the facts differ, most don’t know that the screw compressor is one of the most efficient superchargers ever built. What does this mean? Massive torque levels that are simply unmatchable while simultaneously producing mind-boggling horsepower. No other supercharger in the world can offer this type of torque down low with the incredible top end horsepower. Who wants to wait for the power when you can have it instantly!


Whipple’s Superior Engineering:
Other companies claim to be leaders, but the facts are simple, Whipple Superchargers are years ahead of the competition in all the testing aspects. Each Whipple SC System comes with a recalibrated stock ECU that has all the proper modifications to control idle, fuel, spark and most importantly, diagnostics such as knock control. Only Whipple can modify your stock 555 ECU to work with the supercharger. Most companies today just offer a “FMU” which is just a glorified way of not having much control. With today’s factory ECU’s gaining sophistication, “FMU’s” are simply unsafe and unpredictable in the marine environment. Stock calibrations were never intended for force induction, with this being said, knowing every parameter in the ECU (nearly impossible), you could not ensure proper operation in all intended circumstances, especially without the proper instrumentation. Some companies actually give you a “window” for fuel pressure settings, some can vary 10-15lbs. This is simply staggering, your engine could vary over 2 full air fuel ratios! Most OEM engines cannot take the abuse of being wrong, how do you know which way to vary, why is it not precise and accurate?

No other supercharger company has more money invested in state-of-the-art dynamometers that include cylinder-to-cylinder air fuel sensors as well as full combustion analysis. Whipple spends millions of dollars every year in research and development, constantly doing whatever it takes to stay on the cutting edge of technology. When you install and run one of our systems, you’ll see first hand the amount of engineering and technology that goes into every system.


Whipple’s Superior Packaging:
Simple fitment is always a given when it comes to a Whipple SC system, but what is very unique and equally important, the look. Were talking about boats here! Why would you want a gizmo hanging from the side, not matching the factory fit and finish when you could have something that looks OEM installed with superior performance? Whipple SC systems are well thought out and are made to fit in even the most non-applicable applications. With a matching black finish, the Whipple system has again set the standards in the marine industry. Only 2.75” is needed in front of your engine and the SC is the same height as your factory engine cover, a perfect fit for almost all applications..

Stage 1 and 2 are now shipping!

Stage 1 $795
The Whipple Stage 1 system is a computer recalibration that increases the maximum rpm level while maintaining a conservative timing curve for 87-octane gas. This calibration is designed to be conservative and reliable like stock, but a higher maximum rpm level for more prop selection. Stage 1 achieves only modest power increases such as 15 foot-pounds of torque and 10 horsepower.
Key features:
• 5450 RPM limit
• 87 octane safe

Stage 2 $995
The Whipple stage 2 maximizes the power output of the stock engine by running 91 octane or better, increasing the maximum spark advance, increased ignition power from the individual coils, denser air charge from the low temp thermostat, maximized air-fuel ratio in each individual cylinder and increased air flow from the hi-flow filter. Calibration increases torque levels throughout the entire rpm curve while making more peak hp for increased speeds.
Key features:
• Hi-performance ECM calibration
• Low-temp thermostat
• Hi-flow K&N filter
• 5450 RPM limit
• 8% - 10% power increase over stock
• Increased plaining ability with increased torque output

Stage 3 $4595
While Stage 2 gets peak power from the stock engine, Stage 3 combines power and looks together for a very unique package. After extensive testing, Whipple found the CMI E-Tops to produce the best power curves for the 496 engines. To go along with the stainless headers, Stage 3 incorporates a custom stainless engine cover to really dress the package up. Whipple then engineered a custom Stage 3 calibration that increases the maximum spark advance, ignition power from the individual coils, denser air charge from the low temp thermostat, maximized air-fuel ratio in each individual cylinder and increased air flow from the hi-flow filter. Calibration increases torque levels throughout the entire rpm curve while making more peak hp for increased speeds.
Key features:
• Hi-performance ECM calibration
• Low-temp thermostat
• Hi-flow, custom billet flame arrestor
• Polished stainless steel engine cover
• Polished stainless steel CMI Platinum E-Tops
• 5450 RPM limit
• 12% - 15% power increase over stock
• Over 40 foot pounds of torque over stock at 3500 RPM

Stage 4 TBA
The Stage 4 goes deep into the engine to maximize the power level out of the engine. Whipple designed this to be a 525 horsepower engine that maintains rugged durability levels and incredible OEM like reliability. Stage 4 utilizes the polished CMI Platinum E-Tops headers, reworked cylinder heads, custom camshaft and valve train components with a custom computer calibration. The results are 525 HP, 600 foot-pounds of torque on 91 octane. Motor starts up, idles and runs like stock with a large increase in power throughout the rpm range.
Key features:
• Hi-performance ECM calibration
• Low-temp thermostat
• Hi-flow, custom billet flame arrestor
• Polished stainless steel engine cover
• Polished stainless steel CMI Platinum E-Tops
• 5650 RPM limit
• 91 octane
