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 improved 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 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 can support up to 700hp.
