The original PhatShaft 64 features a 64mm compressor with extended tip technology. The wategate is set at 45psi. All PhatShaft turbochargers are equipped with dual grooved bearings and an adjustable boost elbow. The original PhatShaft compliments moderate fueling upgrades and can support 350 – 600hp.
