Whipple Twin Screw Supercharger FAQ
Why would I want to supercharge my vehicle?
Supercharging increases air density and significantly increases power on an otherwise
stock engine. In short, supercharging makes a V-6 perform like a V-8 and makes
a small block V-8 perform like a big block V-8. OEM manufacturers like Ford, GM,
Mazda, Mercedes, and Jaguar offer factory installed superchargers on several models
due to the tremendous benefits. Our supercharger systems offer more torque and
horsepower per dollar than any other single engine modification. Most other modifications
available require specific matched parts, in-depth tuning, are not smog legal,
and won't produce the performance gains you'll receive from just the simple addition
of a supercharger system. Продажа квартир Ялты http://www.ugbest.ru. Квартира Симферополя.
What about Whipple Superchargers customer service?
We believe our reputation for service stands alone in the automotive, racing and
the marine industry. We challenge anyone to dispute this claim. Talk with anyone
of our thousands of customers or dealers across the U.S. and get first hand information
about our "CAN DO" attitude. If you’re fed-up with stories about
fuel system problems, incomplete kits, poor performance, lost shipments or computer
problems, give Whipple a try. We promise you won’t be disappointed, we don’t
make excuses, we just "MAKE IT HAPPEN."
Will the factory warranty be void?
It is illegal for a Dealership to void your warranty simply because you have modifications
to your vehicle. It is the Dealerships responsibility to prove that any modification
was the reason for a failure. With that said, some Dealerships are more performance
orientated and willing to work with customers. It would be our suggestion to consult
with your local Dealership regarding their warranty specifics.
Will a supercharger affect my engine life?
One of Whipple’s main goals is to provide the most reliable systems available,
this is why Whipple Superchargers go to such great lengths to get the systems
correct. Nobody does more testing than Whipple. Whipple also utilizes a unique
bypass valve design, which lets engine life be unaffected. Our system is so efficient
and produces such useable torque, that you are rarely at full throttle for any
length of time. When you are at cruise speed or idle, the bypass allows the engine
to breathe normally, no boost. Only when you depress the throttle aggressively
does the bypass close and you have an instant 6-psi of boost. The combination
of our unique bypass valve and reasonable amounts of boost, engine life is not
effected. недвижимость в Ялте тут- http://flatbuy.su. Квартиры, дома
The primary cause for premature engine wear and failure
are detonation and increased RPM. Whipple Industries supercharger systems integrate
fuel system controls such as calibrated proms or interface computer systems. These
management programs virtually eliminate any potential for detonation. Our superchargers
deliver maximum power at a lower RPM than the engine did before supercharging.
This low speed torque and horsepower enables our customers to operate their engine
at a lower speed. This lower operating speed can actually enhance engine life
and increase fuel economy.
What’s the performance difference of the Whipple
Charger and Centrifugal superchargers?
The major difference between the positive displacement
Whipple Charger and today’s centrifugal superchargers is the rate of boost.
The Whipple Charger creates boost the instant the throttle is touched usually
reaching full boost by 2000 to 2400 rpm. The centrifugal supercharger is a belt
driven turbo that has a lag time while it "spools up." The centrifugal
commonly does not come into boost until 2600 to 3000 rpm and they commonly do
not reach full boost until max rpm. Whenever the Whipple Charger has more boost,
your engine has more power giving you far more net power.
The instant boost gives you far better throttle response
whenever you call upon it, far greater acceleration, and incredible drive-ability.
A good example is when you’re towing up a hill at 3000 rpm and you need
more power. If you give it some throttle with the Whipple Charger, you’ll
get 6 lbs. of boost, if you have a centrifugal, then you can’t get that
6 lbs. of boost unless your at full rpm. This boost graph better illustrates the
boost characteristics of the Whipple Charger and centrifugal superchargers.
Do I have to make any internal modifications to my engine?
No internal modifications are required. Whipple supercharger systems are designed
for easy bolt-on installations to stock motors while offering the ability to adapt
to modified engines if needed.
What is the difference between the Whipple twin-screw compressor
and a common roots-type supercharger?
The Whipple twin-screw supercharger is actually a compressor, which means it compresses
air internally as well as compressing it in the manifold. Because the screw compressor
compress’s the air inside the case, air enters into the pressurized environment
with very little leakage or energy loss. A roots-type supercharger sweeps atmospheric
air into the manifold and is compressed in the manifold only. With manifold pressure,
air leaks back through the rotors causing air to be heated. Roots-type uses Teflon
to try and seal the rotors to cure this, but touching tolerances cause more frictional
heat and greater parasitic losses. This problem is multiplied when boost levels
rise or sustained in-boost periods. Automotive and Marine roots-type superchargers
have more tolerances between the rotors and case so they live longer, but this
causes more leakage back through the rotors. A screw compressor has very tight
tolerances between the rotors. The rotors never touch, eliminating big parasitic
and frictional losses as well as keeping the same performance year after year.
The two types of superchargers have different performance
characteristics that have led to several debates on which supercharger is preferable.
Proponents of roots blowers argue that more boost is available at lower RPM to
provide off the line acceleration. Centrifugal supercharger enthusiasts argue
that roots blowers are limited at higher RPMs and can increase air temperature
and decrease horsepower. Paxton Superchargers offer significant horsepower at
low RPMs with superior mid and high RPM performance. In situations where you demand
performance from your vehicle, you are spending most of the time in the mid to
high RPM ranges.
Why should you choose a Whipple Supercharger System over the competitors?
There are many reasons why you should choose a Whipple Supercharger System, but
we feel it’s the whole package that truly makes the Whipple unique. For
starters, all our EFI kits are 50-state emissions legal and come complete down
to the very last nut and bolt. Our fuel and engine management systems are simply
the most advanced of all the aftermarket supercharging companies. In fact, Whipple
is one of the only supercharging companies supplying customers with custom chips,
EPROM’s, and Interface computer systems with today’s EFI engines.
Noise is another important factor, the Whipple Charger has the lowest noise level
in the industry. Our quality and commitment to excellence is shown with our OEM
looking kits and OEM quality parts. The Whipple Charger’s performance characteristics
is a great advantage as well, with the incredible throttle response, acceleration,
and top end power, Whipple Superchargers are second to none.
What is the efficiency of the Whipple twin screw compressor
compared to the roots and centrifugal type superchargers?
The Whipple twin screw compressor is 75% to 85% adiabatic and volumetric efficient
while the roots is commonly 40% to 55%. Common centrifugal superchargers have
a peak of 65% to 80% but do just that, peak. Over an entire rpm range, a screw
compressor has an average efficiency far greater than the roots or centrifugal.
Take a look at the efficiency graph, which illustrates the screw compressor efficiency.
Is the Whipple Charger noisy?
No, the Whipple Charger is the quietest supercharger in the industry. There is
only a slight whisper at high rpm.
Why does Whipple use Cupronickel intercoolers for marine?
With Whipple’s continued quest to provide customers with the latest and
greatest technology, Whipple contacted Garrett™ (one of the world leaders
in intercooler design and technology) to create a better intercooler than today’s
aluminum types. Copper has been proven to be a far superior to that of aluminum
in thermal conductivity, this offers almost twice the efficiency of aluminum.
Cupronickel cores are corrosion resistant making them very durable in all water
conditions, while aluminum cores have serious problems with biofouling and corrosion.
Whipple Supercharger Maintenance
It is recommended that the following items be inspected at all normal engine service
