Silver Bullet PhatShaft 64 – (74mm Low Back Pressure T-wheel) More than two fueling upgrades – We built the Silver 64 as a compromise between the Silver 62 and the Silver Bullet. 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. 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.
