Holy Crap!!!!

The W510R (8.3 Liter) twin-screw supercharger was designed from the ground up to make a simple upgrade to outdated technology such as the 671-1471 roots-type supercharger. Gains of nearly 300hp have been achieved at boost levels of 15psi of boost in some applications giving engines new life and the power everyone craves!

Utilizing a 1071 as its inspiration for fitment, Whipple engineers developed a top entry twin-screw that is interchangeable with 671-1471 roots blowers on applications today. With the standard roots-type opening on top making carb adapters and injector hats a simple swap, Whipple also incorporated the standard roots-type drive snout style to help with easy conversions allowing customers to use their drive snouts in most cases.

The W510R doesn’t stop there though, using some later technology, each Whipple W510R features a bypass valve system which equalizes the pressure above and below the supercharger. This helps reduce idle surge, power consumption and discharge temps during vacuum operation.

Whether you’re running gasoline, E85, E98 or methanol, the Whipple W510R can help extract far greater power levels from your engine.

Air bypass system for unique idle quality and increased fuel economy (vs. no bypass)

50-300hp* gain over traditional roots-type superchargers

Incredible power range, from 800-1500hp on gasoline

Industry leading efficiency, over 92% VE

Increased thermal efficiency over roots-type superchargers

Universal fitment with existing 671-1471 intake manifolds and intercoolers

Universal fitment with existing 671-1471 carb adapters and mechanical injector hats (top entry)

Universal fitment for 671 style drive snouts and adapters

Incredible air/fuel distribution

Lowest noise level of any supercharger

Optional 16-rib serpentine belt system for better pulley and belt selections (marine only)

8mm and 14mm belt systems also work

I did run into a guy in 2016 at the Car Craft Summer Nats in BG that had a sbc with one and efi. It supposedly made 900 hspr and he got 15 mpg...
