Whipple 15+ Mustang GT Gen 4 W175FF (2.9L) Stage 1 SC Kit / Intercooled / 10-11psi / Black

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

NOTE: Flare tool and Flight Control software now included STANDARD.

CARB Approved EO # D-231-45

If you want the most advanced, most powerful, most upgradeable and highest quality system available, then here it is! Whipple Superchargers has yet again set a new precedence for bolt-on power and industry leading durability.

Nobody puts more time and resources into the development then Whipple. The proof is in the product, more power per lb of boost than any other system. The key to making such incredible reliable power is in the Whipple unique twin screw supercharger, massive air-to-water intercooler, oversized Crusher air system and innovative PCM programming that keeps the power-train safe and secure. Whether you’re looking for a daily driver that needs a little more punch or you’re craving a tire-frying, rubber shredding street machine, the Whipple Supercharger systems delivers like no other SC system today. Power from tip in to redline, the new Whipple SC system makes incredible power across the entire rpm range while maintaining industry leading drive-ability.

With years of OEM and racing experience, Whipple engineers have developed a unique PCM calibration that reconfigures all the necessary engine functions including fuel, spark, knock detection, torque management, transmission control and electronic throttle control. The vehicles PCM constantly monitors the engines torque output while monitoring many different parameters to keep the engine in it’s ideal parameters. If a parameter falls below specification, the PCM will lower boost and torque output until the problem can be cured. No other calibration in the field has such technology, giving the Whipple SC system unheralded performance and reliability.

Why front feed? We gained nearly 1.75" in intercooler core and plenum volume to maximize power and power robbing restrictions. Giving us the biggest ic core while also having the biggest area below the ic and the side of the sc. This results in significantly lower pumping losses and lower IAT's. Not only does it have a large plenum below and on the sides, the front feed also has significantly open surface area above the IC core giving lower pressure drop and more effective cooling. The center discharge again allows for less pressure drop and more uniform airflow over the core. Resulting in better distribution and better cooking capacity.

During airflow, every turn is a possible restriction, requiring inlet losses and lower supercharger efficiency. The front feed minimizes the inlet losses resulting in lower losses and higher supercharger efficiency.

The lightweight tapered stainless steel jackshaft is .75" lower than a front feed, which helped with the intercooler size. It also allows torsional twist, helping belt systems and other components from the typical reciprocating mass issues.

Each system comes with a heavy duty spring loaded tensioner and adjustable idler system for multiple belt and pulley options. Also available is a 10-rib belt system using a ATI balancer. Systems are easily upgradeable. Because the supercharger is bigger, the sc uses larger sc pulleys for the same boost as others, resulting in better belt contact area and less belt slip.

The S550 now also features a heat exchanger that is 60% larger than previous generations, standard with every kit. Also available is the dual spal 11" electric fan kit. Each system also comes with an oversized ic reservoir, again significantly ahead of the competition. Holding nearly 1.3 gallons of liquid in just the reservoir alone! Nearly double any others. Big heat exchanger, big reservoir, dual fans equal bigger power gains, more consistent power and light years ahead of the competition. No need to spend. Thousands upgrading budget systems, get it all as standard with every kit.

FEATURES:
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
Front feed 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, nothing comes close
Massive oversized aluminum intercooler reservoir (over 2 gallons) holds more than double any competitors IC water system allowing longer more consistent power
Whipple Superchargers massive oversized intercooled air-bypass system for industry leading reduction of burst knock and incredible fuel economy
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 or 4x4 roots
Center discharge port for better cylinder to cylinder distribution then other twin-screws with cobbled together billet adapters and forward facing discharge
W175ax SC bottom is open for increased plenum volume and better over-intercooler air distribution giving more intercooler effectiveness
