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
New from Whipple is the 2.9L front feed system for the 2014+ GM Truck / SUV with the 5.3L DI (direct injection) motor. This kit brings the HP up from 355bhp to 525bhp with 7.5psi of boost on 91 octane fuel. No fuel system is needed for this set up as is. Dyno sheet for the Whipple test truck (2014 Silverado 1500 single cab, short box, 2wd) is also available to view the power graph (shown in RWHP).
