03-04 Dodge Cummins II Silver Bullet Phat Shat 64 Turbo - SBPS6480CR

The Silver Series PhatShaft is our latest effort to achieve perfection. Much like the Super PhatShaft it was designed to handle multiple fueling upgrades and comes in three sizes 62mm 64mm, and 66mm. What separates the Silver Series PhatShaft from the Super PhatShaft is our new technology 74mm turbine wheel. To improve on the Super PhatShaft turbos we needed improve performance at a lower rpm range and we needed to reduce compressor surge. The solution is the 74mm turbine which is the latest in turbine trim design technology. The new trim design transfers exhaust gas energy more efficiently than any other turbine on the market. It also allows for better exhaust gas expulsion which results in lower EGT’s and quicker rotor acceleration. The most important benefit of the 74 mm turbine wheel is that it gets rid of turbo surge and broadens the power range. All silver series turbo come with a 360 degree thrust bearing and an appealing polished compressor housing. The Silver series utilizes the proven 14cm exhaust housing with a modified exhaust nozzle. We maximize the wastegate ports in the 14cm housing by enlarging the diameter. The turbine housing wastegate cover it custom build to allow full wastegate travel. Like all PhatShaft turbochargers they are equipped with dual grooved high performance bearings and an adjustable boost elbow. We built the Silver 64 as a compromise between the Silver 62 and the Silver Bullet 66. The Silver 64 was designed to handle multiple fueling upgrades and is equipped with an extended tip 64mm compressor wheel. The Silver 64 comes with a polished compressor housing and 360 degree thrust bearing. The Silver 64 uses a 14 cm exhaust housing in which we modify the angle of the exhaust nozzle, maximize the wastegate ports and enlarge the wastegate chamber for full wastegate travel. Like all PhatShaft turbochargers it is equipped with dual grooved high performance bearings and an adjustable boost elbow.
