The summary of ‘Which Supercharger is Best for You? Centrifugal vs Twin Screw’

The video discusses the differences between positive displacement and centrifugal blowers in superchargers, focusing on their performance characteristics, heat generation, and suitability for different racing applications. Positive displacement blowers offer immediate torque ideal for drag racing, while centrifugal blowers are preferred for road racing due to lower heat generation and top-end horsepower. Various vehicle models like the 0304 Cobra, Hellcats, and Chevy models are highlighted for using positive displacement blowers. The choice between the two types depends on the racing application, desired power characteristics, and traction requirements, with different supercharger brands like Whipple, Edelbrock, and Vortec catering to various needs.

In this segment of the video, Scott from Steed Auto Sports discusses the difference between positive displacement blowers and centrifugal blowers in superchargers. Centrifugal blowers are belt-driven, producing a whining sound, requiring RPM to create boost similar to turbos. Positive displacement blowers provide instant torque with a volume of air sitting on top of the motor, ideal for immediate response and seat-of-the-pants feel. Positive displacement blowers are commonly found in production vehicles like the 0304 Cobra, Hellcats, and Chevy models due to their simplicity in packaging and immediate torque delivery.

In this segment of the video, the speaker discusses the advantages and disadvantages of positive displacement and centrifugal blowers in terms of heat generation and power output. Positive displacement blowers create more heat due to directly connecting to the cylinder heads, forcing more air into the engine for increased power. They come with a built-in heat exchanger. Centrifugal blowers are preferred for road racing due to lower heat generation, while positive displacement blowers are better for drag racing for instant low-end torque. The choice between the two depends on the racing application, traction, and desired power characteristics, with different superchargers suited for different needs and markets.

In this part of the video, the speaker discusses the positive displacement and centrifugal style superchargers. Centrifugal superchargers produce a distinct winding sound, akin to an F-14, and provide top-end horsepower. They also offer instant torque, which can be adjusted by changing the pulley size for better traction. Supercharging is highlighted as a convenient power upgrade option compared to nitrous or turbos, with brands like Whipple, Edelbrock, and Vortec mentioned as quality choices.
