Silver Bullet PhatShaft 66 – (74mm Low Back Pressure T-wheel) More than two fueling upgrades – The Silver Bullet is our latest effort to achieve perfection. Much like the Super PhatShaft 66 it was designed to handle multiple fueling upgrades and comes equipped with an extended tip 66mm compressor wheel. What separates the Silver Bullet from the Super PhatShaft 66 is our new technology 74mm turbine wheel. 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 EGtï¿½s 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 band range. Another identifying characteristic of the Silver bullet is the polished compressor housing. The Silver Bullet 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 The Sliver Bullet can support over 800hp and is the best all-round turbo on the market today.
