The Magnum Performance M480/78 turbocharger is designed with the professional drag racer in mind. Inspired by the traditional S400 compressor frame design and with Magnum's advances in full system simulation technology (free with the purchase of a turbo). The industry's fear for boost creep due to smaller diameter (78mm versus 86mm) turbine wheels has become a myth. The fact is that a smaller diameter turbine wheel has lower inertia and hence faster spool up characteristics. Our engineers have mastered the ability to give you faster spool, higher top end power for nearly half the price of our competitors units and with the best warranty in the industry.This unit features an optional Silicon-Nitride Angular contact Hybrid Ceramic Ball Bearing with Water and Oil Cooled CHRA. A unit that also comes standard with our 1 year warranty. With an optional Billet Wheel upgrade and 1300+ HP Capabilities its a great single turbo option for the big displacement 8, 10 and 12 cylinder applications such as the Dodge Hemi 6.0L , LS Powered Chevy 6.7L and 5.4L ford alike. Also a great twin turbo option for the Pro stock, and Pro modified nitro-methane race vehicles.
