The original PhatShaft is the perfect upgrade turbo for towing. The PhatShaft can be purchased with a 12 or 14 turbine housing matched with a 65mm turbine. We suggest a 12 cm turbine housing if the truck is a 12 Valve and has moderate fueling upgrades such as 300hp injectors and a camplate. If the truck has heavier fueling upgrades such as aggressive fueling electronics, 370hp injectors, aggressive camplate and/or governor springs then you will be better suited with 14cm housing. The benefit of the 14cm exhaust housing is lower Exhaust Gas Temperatures but it will be slower to spool in daily driving situations. The original PhatShaft is available in 3 different compressor sizes, 62mm, 64mm, and 66mm. All three compressors have extended tip technology. The wategate is set at 40psi to prevent head gasket failure on the PhatShaft 62 and 45psi on the PhatShaft 64 and 66. All PhatShaft turbochargers are equipped with dual grooved bearings and an adjustable boost elbow. The original PhatShaft compliments moderate fueling upgrades and can support 300 - 550hp.
Silver 62/64 Siver Bullet
The Silver 62 is our latest effort to balance the demands of towing and performance. Much like the Super Phat Shaft 62 it was designed to handle multiple fueling upgrades and comes equipped with an extended tip 62mm compressor wheel. What separates the Silver 62 from the Super Phat Shaft 62 is our new technology 74mm turbine wheel. The identifying characteristic of the Silver 62 is the polished compressor housing. The Silver 62 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 Phat Shaft turbochargers it is equipped with dual grooved high performance bearings and an adjustable boost elbow The Sliver 62 can support up to 650hp and is the best all-round turbo on the market today.
