Twin Screw System

Whipple’s latest generation twin screw supercharger — designed, assembled and manufactured in the USA, with exclusive improvements that raise efficiency, lower operating temperature and extend service life.

EXCLUSIVE IMPROVEMENTS

MADE IN USA

Designed, assembled and manufactured in the USA.
HIGH-FLOW ROTOR COATING

Enhanced efficiency and durability from a high-flow rotor coating.
MORE BEARING LUBRICATION

Increased bearing lubrication reduces operating temperatures.
SERVICEABLE DESIGN

Replaceable and upgradeable components instead of a sealed unit.
UPGRADED BEARINGS

Double angular front bearing with a sealed roller rear bearing.
OIL SIGHT GLASS

Check oil level at a glance, no disassembly required.
100,000-MILE OIL INTERVAL

Long service intervals on the current Whipple compressor.

Why Twin Screw Wins

Why Twin Screw Wins
	Whipple Twin Screw	Centrifugal	Turbo	Roots
Response	Awesome idle-to-redline rpm power. No lag.	Poor low-speed response, similar to "turbo lag."	Poor low-speed response. Turbo lag.	Good low to mid-range power.
Driveability	Increased lugging ability in higher gears. Increased power throughout rpm range.	Must downshift to maintain boost level.	Must downshift to maintain boost level.	Increased lugging ability in higher gears.
Engine Torque Curve	Virtually flat curve; ideal characteristic.	Often worse than uncharged engine at low speeds.	Often worse than uncharged engine at low speeds.	Wide range; fall-off can occur at high speeds.
Heat Buildup	Low; intercoolers are usually not needed.	Low; intercoolers are usually not needed.	High; may need intercooler.	High; limits boost available.
Noise	Very low noise levels.	Typically very noisy.	Very low noise levels.	Typically very noisy.
Adiabatic Efficiency	70-85%	60-78%	60-75% Peak	30-65%
