Why not add a Supercharger?

[jhnmdahl]

A 50% jump in horsepower on 5% boost? Those numbers don’t add up. I’d expect something more like 525-540hp, given you have 30% more air at best.

Mic DROP!!!!!!!!!!!!!!!!!!

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 5lbs. 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%!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Whipple’s Superior Engineering:
Whipple Superchargers is the only licensed company to recalibrate the factory 496 PCM’s. 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.

SOME EXCLUSIVE FEATURES:

Up to 50% horsepower increase
EXCLUSIVE reprogrammed ECM for complete engine management including fuel, spark and detonation protection
Instant boost, no lag as does centrifugals
Cupronickel intercooler core for complete corrosion resistance
Heavy duty intercooler design for increased durability and reliability
Throttle body injection creates liquid intercooling for even lower air temperatures, increased power and reliability
Ultra efficient 3.3 liter Whipple Charger
Flat torque curve across wide RPM range
Completely self contained oiling system
Most efficient supercharger on the market
Easy to install without internal engine modifications
Supercharger has lowest noise level in industry
Black powder coating and anodized pieces
Major kit components are pre-assembled for easy install.........

I love it. Do they have one of those ECU's for my volvo mefi4 ?
Can I add and get it to 100%
Why is volvo left out in that dark?

No chance I boost an engine that needs to turn 6,000 RPM. I don’t trust the rods.
Gimme 502 twins.. I'm good.

That was supposed to say add 2 and get 100%

Air at sea level is just shy of 15psi, so adding 5psi gives you a theoretical maximum gain of 33% of your original air (usually less due to a variety of real-world losses). It looks like Whipple is achieving greater gains than this by changing a bunch of other things with the engine too, including ecu mapping, throttle body, bigger injectors at higher pressure, etc., which means the HP gains are likely about half due to the supercharger and half due to the other modifications. In other words, if you throw out the supercharger but kept the rest of their parts and re-tune in the same way they have, you'd probably still be up by around 25% in horsepower over the stock engine

If you try to supercharge a modern well-tuned engine that hasn't left much on the table with their ECU tuning and doesn't have a poor intake and/or fuel system design, you're typically limited to less than the theoretical gain as described above.

That said, I like superchargers a lot, and wish my BMW had an Eaton supercharger instead of the twin scroll turbos. It's unfortunate that Audi moved away from the TVS superchargers in their 3L engines toward turbos, but they save a buck and have higher peak horsepower numbers to advertise despite the hit that throttle response takes.

6000 rpms 496 runs between 5000-5200rpms. Maybe your talking about the 350 mag

I put a Whipple on my 2001 Chevy Suburban tow vehicle back in 2000, when my truck was new. The only other mods were to make the exhaust free flow. The vehicle had enormous torque, in fact the only problem I've had is breaking transmission input shafts. I finally found a hardened one that has lasted. It was fun to blow off Mustangs as stop lights. I did the install with two of other knowledgable guys in one evening. At that time Whipple sent a modified ECU, for the Chevy small block.

I have a 1999 292 with twin 350and Bravo 3s, and it is fast enough for me on Lake of the Ozarks, which has a constant boat chop, unless you out very early in the morning. That "big pig" handles the wakes as well as any boat I've driven or ridden. Also, I wonder if there is enough top clearance for the Whipple in my application. I suspect not.

Volvo uses the newest generation GM marine motors which is based off the new LT series V8 that you see in the latest gm trucks. So they are a all aluminum small block. Direct injection. So get the same power as the old big blocks. Just spin a little more rpm’s

All the more reason to add a whipple supercharger!

Resurrecting this!

I was looking at either a heads/Cam package for my 8.1Gi or maybe dipping into the SC route. I’m a big fan of the ProCharger centrifugal setups but I can’t find one for a Volvo setup. Next option would be a twin screw. Any of y’all endup going that route? Who can tune the Volvo ECU’s? It’s a 01 so the ECU should be the tuneable one. I’ll need that regardless of what direction I go, this is what I was looking at.
