The new larger displacement 235ci Whipple supercharger for the 5.0L Coyote now boast a displacement of 3.8L versus the prior models 3.0L size. This GEN 5 supercharger comes as a complete kit or available as a 3.0L upgrade for existing customers. Increased efficiency and improved operating temps make this the ideal choice for big horsepower builds. A long list of new features like dual intercooler, high flow lid, improved throttle body angle and increased runner length make it the most powerful model yet.

Whipple 3.0L to 3.8L Swap Kits 

Upgrade kits for existing 3.0 Gen 5 owners who want the new 3.8L units include the head unit, intercooler, lid, and engine lowering kit. Upgrade kits are not compatible with gen 2/3/4 supercharger kits. The 3.8 uses the same pulley and bracket system as the 3.0L Gen 5's.

Size and Hood Clearance

The new 3.8L housing appears similar to the 3.0L Gen 5 but dimensionally the new unit is superior. The 3.8L Whipple for the Coyote is .375" taller than the 3.0L but will fit under the stock Mustang hood and cowl with Whipple's engine lowering brackets (which are included in the kits). Most aftermarket hoods will still require this as well.

In Depth 3.8L Supercharger Features

Designed using the technology of the 3.0L Gen 5, this new head unit is larger and more efficient in many ways. The patent pending dual intercooler and matching high flow lid deliver more airflow for repeatable power. The improved throttle body angle and increased runner length help high rpm airflow and still maintain excellent low end torque. 

• New patent pending dual intercooler for improved efficiency
• New high flow fittings, dual in, dual out, 12an and 16an
• New CFD based inlet design for greatly improved efficiency 
• New rotor inlet shape for increased airflow
• New tilted throttle angle for increased airflow
• New, higher flow lid for improved cylinder distribution
• Increased runner length for increased torque/throttle response
• New Whipple rotor profile
• Increased diameter vs length for optimum efficiency
• Updated front pulley and bearing design
• With or without race port

The rotors offer a 6% increase in flow efficiency for better boost characteristics. The larger rotors (right) compared to the 3.0L (left) are designed for serious power capabilities.

All applications will be offered with the 3.8L Gen 5 upgrade, including the 2020 Shelby GT500, F150 Truck, Hemi and of course the popular GM models with LS or LT powerplants.

Dodge HEMI 3.8L 

Insiders pick of the 3d Printed Prototype of Hemi 3.8L. High demand for the Big GEN 5 upgrade, this will fit the Hemi 5.7, 6.1 and 6.4L engines, along with upgraded head units for the Hellcat Charger, Hellcat Challenger, Demon and Red Eye. This system includes a Patent Pending Dual Core Dual Pass Intercooler Design that fits under the stock hood and cowling. Need more info? Read more about the upcoming Whipple 3.8L Hemi Upgrades. 

Shelby 2020 GT500 Upgrades

From the factory the GT500 supercharger works well but needs a few upgrades to get serious horsepower levels. Direct from Whipple, more power is possible. In prototype form, you can see the new design and the similarities to the 3.0L but the larger inlet and dual intercooler truly are designed for built motors and maxx power. 

The new 3.8L GEN 5 will be out soon, but until then, Whipple offers a few important upgrades to help airflow and cooling for more horsepower. Add these upgrades with tuning, headers and exhaust for a healthy increase in power. 

Billet Hi Flow Intercooler Manifold (Learn More & Pricing)

The billet manifold, which is Type 2 black anodized fits directly in the stock location with no modifications required. Whipple's all new, 6061-T6 billet intercooler manifold not only looks incredible, it flows more fluid than the stock cast design. With a full modular design, you can simply install in a stock system, with stock lines and stock intercooler core, or you can couple with the Whipple Billet Super High Density upgraded intercooler core.

Super High Density Intercooler (Learn More & Pricing)

Sharing the same technology that helps push the Whipple Superchargers to race win after race win, the all new, super high density GT500 intercooler core is now available to help keep GT500’s manifold air temps under control, even with increased airflow where the stock system begins to quickly run out of capacity. The new core features 33% larger inlet and outlet water passages, for significantly increased flow capacity over stock or other aftermarket intercooler cores. The SHD (super high density) offset fin design allows increased cooling capacity in the same area vs standard density fin. With the billet flange, the SHD core was able to utilize 10% more surface area for increased cooling capacity. Put all this together and you have a more efficient intercooler that fits with the stock supercharger system, while being upgradeable with our intercooler manifold.

Billet Spring Loaded Pulley Tensioner (Learn More & Pricing)

Tired of breaking stock tensioners, running out of adjustment and suffering from belt slip? Whipple's engineering team built a all billet spring loaded tensioner that is a direct replacement of the stock unit. The billet tensioner features 6061-T6 material, black anodized finish, dual bearing for robust arm control, 18deg of increased travel over stock (50deg vs 32deg) and optional dual bearing idler pulleys for different crank pulley diameters. Tech Note: Due to change in geometry, belt lengths change. For stock pulley configurations, a Gates K080680 is ideal. Pully diameter changes will require different belts.
