Twin-Screw Blowers
|
|
|
Because of its ability to produce an abundance of boost at virtually any engine RPM without any
supercharger lag, the twin-screw compressor has become one of the most popular choices for
contemporary street supercharging. Former NHRA Top Fuel and Funny Car racer Art Whipple was
highly instrumental in introducing twin-screw compressor technology to the world of drag racing. He
also went on to popularize the concept with the automotive performance aftermarket by developing
a complete series of GM-derived, Lysholm-based Whipple twin-screw supercharger kits.

Kenne Bell offers a number of
twin-screw supercharger kits,
including kits to upgrade your
factory supercharged Cobra
and Lightning, and kits to
supercharge your naturally
aspirated Mustang or truck.

Simultaneously, Jim Bell (Kenne Bell, Inc.), long known as the builder of some of the fastest and
quickest Buick Grand National cars in the country, began experimenting with the Autorotor-derived
twin-screw compressor. The by-product of that grand experiment was the 1.5L Kenne-Bell TS-1500
twin-screw supercharger kit for the 1986 and up 5.0L pushrod V-8 engine Mustangs. But how does
the twin-screw compressor design really work?
“The basic engineering philosophy behind the creation of the twin-screw compressor is that the
shortest, smoothest path between two points is always best for optimum airflow,” commented Jim
Bell.
Bell went on to explain that depending on the application, as air enters through the rear or top rear
of a Kenne Bell twin-screw supercharger case, the “male” rotor rotates clockwise while the “female”
rotor rotates counterclockwise to internally compress the air producing a much higher VE. This is
opposite of the operating principles of a Roots design, which is considered to be a semi-blow-
through design.

Kenne Bell’s 50-state-legal 1.5L bolt-
on TS-1500 Twin-Screw
Supercharger Kit for the 1986-1995
5.0L pushrod V-8 engine Mustangs
delivers 6 to 8 psi.
|
|
|
|
|
|
“This was done to avoid pumping air between the rotors and case,” says Bell. “This more efficient
method of internal compression also reduces the high turbulence, friction, and heat buildup (known
as adiabatic efficiency) inside the case during the process of trapping and compressing the air
between the rotors, ultimately producing a lower air-charge temperature. The significantly
compressed and cooler air charge is then screwed, or propelled, toward the front of the case,
where it’s discharged into the engine.”
Due to its superior design, the twin-screw compressor also requires (depending on the size of the
supercharger drive pulley) 10 to 16 less horsepower to drive, a noteworthy reduction in parasitic
loss. Of course, the end result is increased horsepower and torque at any operating speed, which
equates to increased acceleration for quick starts, straight-line running, passing, towing, or hill
climbing. “It’s like having a big-block under the hood,” says Jim Bell with a huge grin.
Although Kenne Bell offers a total of nine different sizes of self-cooled, self-lubricating twin-screw
superchargers, there currently are three different sizes used in their Ford-specific kits. Each of the
Autorotor-based Kenne Bell street superchargers is 50-state legal.
There’s the billet-aluminum-cased 1.5L TS-1500, which is capable of producing a 40 percent gain
in rear wheel horsepower at boost levels of up to 12 psi max boost. There’s the slightly larger 1.7L
billet-aluminum-cased TS-1700 interim compressor, which is capable of producing between 45 and
50 percent more horsepower to the rear wheels in normal trim, and up to 55 to 60 percent more
horsepower when intercooled at 13 psi. Then there’s the even larger 2.2L billet-aluminum-cased
TS-2200, which Bell and company affectionately refer to as the Blowzilla 2200, capable of
producing 70 to 75 percent more rear wheel horsepower at 18 psi max boost!
All three units occupy virtually the same physical space inside the engine compartment of any
model 1986 to 1995 5.0L Mustang or Ford F-150, or 1996 to 2004 4.6L SOHC Mustang GT or
DOHC SVT Mustang Cobra. Listed below are the specific Kenne Bell Ford applications.

Kenne Bell Superchargers
offers a full line of
Autorotor-based twin-screw
superchargers for Ford,
DaimlerChrysler, and GM
applications ranging from
the 0.87L, 1.33L, 1.5L, 1.7L,
1.8L, 2.0L, 2.2l, 2.4L, and
2.6L dimensions.

These 100 percent bolt-on Kenne Bell supercharger kits look so factory it’s kind of hard to tell
that they’re actually aftermarket. Furthermore, K.B. states that their twin-screw supercharger
kits are the only kits on the market that allow all the OEM engine accessories to remain in the
stock position. Kenne Bell is also working on a 1.7L, 50-state-legal twin-screw supercharger kit
(10 psi max boost) for the 4.6L, 3-valve 2005 Mustangs. “A stock 2005 3-valve Mustang GT is
capable of producing around 279 hp at the rear wheels,” says Bell. “With our intercooled 1.7L-
equipped R&D mule, we’re currently able to produce 460 horsepower!”
More good news! Kenne Bell also offers a fourth model, the 2.4L Blowzilla 2400, which is
capable of operating at an incredible 26 psi max boost. However, the 2.4L Blowzilla is for
competition or “off road use only.”
Of course, no matter what the application, actual boost, torque, and horsepower are relative to
how quick you turn the compressor, and that is governed by the size of supercharger drive
pulley you use.
“A general rule of thumb is that for each 1⁄8 inch in diameter, you will produce 1-horsepower
while simultaneously increasing PSI accordingly. Remember, a supercharger is a pump. As it
tries to pump air into an engine, it (by sheer design) pumps more air than the engine can
normally exhaust – the bigger the (cubic-inch displacement of an) engine the smaller the
pulley. Depending on the actual application and size of the Kenne Bell Twin-Screw
Supercharger being used, we offer over 40 different-sized drive pulleys for Ford small-blocks
and Ford mod motors ranging from 17⁄8 inches to 41⁄8 inches in diameter,” says Bell.

Kenne Bell’s 2.2L Blowzilla twin-screw
supercharger has been successfully
used on all 1996-2003 4.6L DOHC
SVT Mustang Cobra models. The
company has recently prototyped a
system for the 4.6L DOHC engine
Mach 1 cars, at 20 psi max boost.
Shown here is a fully installed 2.2L
twin-screw Mach 1 system showing not
only the blower, but also the
(prototype) shaker hood scoop
brackets, which are an integral part of
the Kenne Bell kit.

How to Build Supercharged and Turbocharged
Small Block Fords
by Bob McClurg
|
|
|
|
|
|
The supercharger and turbocharger in their various forms and
applications have both been around for well over a century.
What makes them so popular? Looks, power, performance,
sound, and status. And how do they relate to, and improve
upon, the performance level of a small-block Ford pushrod V-
8 engine like a 289-302, a 351-Windsor, a Ford 351-
Cleveland, or even the latest generation 4.6L / 5.4L “modular”
small-block V-8 engines? That’s EXACTLY what this book is
all about!
While Ford dabbled in supercharging and turbocharging on
production cars all the way back in 1957 with the legendary
Thunderbird, and then again with Shelbys and over-the-
counter kits, and then again in the late ‘70s and early ‘80s
with turbocharging 4- cylinder applications in Mustangs the
real revolution in supercharging and turbocharging Ford
products has come through the aftermarket in more recent
times. The Fox Mustang, created in 1979, and the platform
that would eventually feature fuel injection in 1986, allowing
much more boost, created a genre of lightning-quick and
affordable performance cars.
Featuring legendary supercharger and turbocharger
manufacturers like Paxton, Vortech, Pro-Charger, Garret-
AirResearch and Power Dyne, as well as traditional Roots-
style systems, this book covers everything you need to know
about supercharging and turbocharging your small-block
Ford. Read the sample pages to learn more!
