Are you ready to really make some power? Do you want to take your 800 horsepower engine to 1000 horsepower? How about your 1000hp motor going to 1200hp? If so, Whipples latest development will fit your needs. The all new 305 series superchargers will truly revolutionize supercharging as we know it. The massive twin screw superchargers not only offer incredible power levels, but also reliable and consistent power levels that are typically unheard of. Within a few hours, you can remove a standard roots supercharger, swap some of your components and pick up another 200 horsepower*. 

The 8.3L superchargers are so technologically advanced to the current roots-type superchargers that there is simply no comparison. The 305 blowers have a standard 671 bolt pattern so they can utilize any existing roots manifold or intercooler setup. The 8.3L’s also utilize standard roots-type drive snouts for many different applications. Whipple offers the 8.3L in two versions, a radial version which utilizes a standard roots style inlet which accepts virtually all carb and EFI adapters. The other 8.3L is the axial entry (rear) which utilizes a custom, billet 3000 cfm capable throttle body. 

The new 8.3L superchargers pump 510 cubic inches of air per revolution and have operating ranges up to 11,000rpm for pleasure boat applications and 12,000rpm for race applications. These new massive superchargers offer two different designs; one is a direct bolt-on replacement for 671-1471 style superchargers (top entry) while the other version is a sleeker, rear inlet compressor for tighter clearance applications. The new Whipple W305’s offer superior adiabatic and thermal efficiency for far greater power gains than any roots-type supercharger, yet they don’t need Teflon strips or constant rebuilding. In some cases, gains of nearly 30% can be achieved by simply using the twin-screw advantage! 

The 510R offers a blend of old-school fitment with new age technology. Whipple offers this massive supercharger in two fitment options, one for the standard roots-type manifold/intercoolers and another for the Whipple Cooler manifolds. Both offer far greater air/fuel distribution than typical roots-type superchargers which allows for greater power levels and more reliable operation. Standard carb adapters and mechanical injector hats such as the Enderle Bug Catcher bolt right on, within minutes. 

The revolutionary superchargers offer a standard 671 style drive snout system to work with traditional 8mm and 14mm systems, an externally mounted air-bypass system for industry leading idle qualities and fuel economy, Teflon coated rotors for increased airflow, extreme duty roller bearings, precision cut helical gears, oil sight glass for easy inspection and a universal 671 style mounting flange.

*Standard, non intercooled version uses a 4" adapter plate for easy fitment to stock 671 manifolds.

*Carb adapter and linkage are not included.

*Works with most common 8mm belt drives and pulley systems.
