Whipple is always pursuing the latest & greatest technology and making any innovation they can to produce the most efficient supercharger on the market. The 2.9L supercharger has been the most popular head unit for the Cobras, GT500s and Coyotes. For this reason, Whipple has focused on improving the rotor & housing design of the 2.9L.
Whipple introduced the Gen 3 rotor upgrade for the 2.9L in late 2017 and it boasted a 30-150hp/tq increase at the same boost level compared to its predecessor. It’s been performing like a beast but Whipple knew they could get more out of the 2.9L so earlier this year they introduced the option to upgrade to the Gen 4 rotor & housing. The Gen 4 upgrade is great for those customers wanting a little extra hp boost but without going full Crusher or crazy small pulley setup. The step up from the Gen 3 was not as big as the 2-3 step, but still makes for a nice little gain. Compared to the Gen 3, the Gen 4 2.9L has a 4% flow increase and will make around 1-1.5 more psi at the same pulley size.
- Adds up to 30-150 hp/tq at the same boost level
- 10-80*F cooler temps
- New Whipple Crusher SC Housing for increased volumetric efficiency
Since 1987, Whipple Superchargers ™ have been the pioneers and leaders of twin-screw supercharging. Whipple was the first to bring positive displacement technology to fuel injected, emissions legal GM applications. With over 26 years of GM twin-screw supercharging experience, Whipple's team have now engineered the most powerful intercooled twin-screw SC system available today for your Chevrolet SS.
With all the latest technology, the all new Whipple system makes more power than any other positive displacement supercharger system on the market giving you tire frying, neck whipping power that will give you a grin from ear to ear. The new Whipple system is 100% complete and is designed for stock engines but has enough capability to work with heavily modified engines. The all-new system features Whipple's massive oversized air-to-water intercooler for unmatched cooling capacity, a unique front feed W175ax (a whopping 2.9 liters) integrated Whipple twin-screw supercharger that reaches 99% volumetric efficiency and industry leading power potential.
The unique intercooled bypass system offers better acceleration and less than 1hp of consumption during cruising for excellent fuel economy. The system also includes high-flow fuel injectors, aluminum high flow intake manifold and a Whipple Flash Programmer from SCT™ for the factory ECU recalibration. While others claim, Whipple Superchargers simply deliver more power per pound of boost than any other supercharger on the market today.
The complete system comes with the high flow air filter element for the factory air filter box, oversized intercooler reservoir that rest behind the front bumper, massive air-to-water heat exchanger for ultra low manifold air temps for consistent power and all the hardware necessary for a simple installation.
The most powerful 50-state emissions legal option available
No other upgrades required, just massive power right out of the box
Front entry W175ax (2.9 liters) Whipple twin-screw supercharger that significantly outperforms competitions 1.9L and 2.3L roots-type systems
Front feed supercharger utilizes precision ground helical cut gears vs a problematic belt.
Integrated casting to minimize bolt on pieces, adapters, leaks and flow restrictions
Integrated Crusher ™ venturi shaped inlet for maximum airflow capacity and minimal rotor cavitation
Integrated Crusher ™ 112mm round inlet outflows smaller 90 and 93mm inlets such as other Eaton based systems
Integrated Crusher ™ 112mm round inlet for optional 102mm throttle bodies
Big Mouth Whipple Crusher ™ plastic air inlet (or optional carbon fiber) for increased velocity and lower inlet temps vs. steel and aluminum tubes
Integrated design allows for oversized intercooler core compared to other smaller intercooler cores giving Whipple lower air charge temps which allows more boost and timing to be run on pump gas
Massive air-to-water aluminum bar-plate intercooler offers more cooling than any other positive displacement system available
Whipple Superchargers massive oversized intercooled air-bypass system for industry leading reduction of burst knock and incredible fuel economy, no ridiculous fabbed steel tubes or systems that circulate hot air
Self-contained oversized oil system for dramatically reduced oil temps in even the most demanding conditions
Exclusive 3x5 rotor combo for significant increase in airflow under the curve than less efficient 4x6 rotor combo
Zero turn inlet allows for decreased induction losses when compared to rear inlet systems and 180deg bends
Center discharge port for better cylinder to cylinder distribution then other twin-screws with cobbled together billet adapters and forward facing discharge
Discharge down design allows for less pressure loss which gives more power at lower boost levels
Top mount design allows for cooler operation then upside down SC's that conduct heat from engine and are trapped by runners and covers, causing hotter manifold temps and less power per pound of boost
More boost at the "hit" than any other twin-screw
Flat torque curve for incredible acceleration
Oversized heat exchanger for incredible intercooler water temps
Fits under factory hood with no modifications
No internal modifications required
Completed installation looks factory installed, not some cobbled together kit with multiple billet adapters
Kits come complete with all necessary parts and hardware for installation
Unique oil level sight glass for easy oil level and quality check, no dipstick to bind or misread
Plug and play wiring with male and female connections
High flow air filter system (50-state legal filter system), coolant reservoir is maintained
