The GT-K family has been designed for maximum performance utilizing the most advanced turbocharger engineering and components. This next generation of turbo units features special Map Enhancement Porting to allow the compressor wheel to operate at its maximum efficiency across a very broad rpm range. This variant of bleed air design, has precisely placed slots machined into the compressor housing to limit effects of surge when using large turbochargers on small displacement engines as well as providing additional air flow to make maximum horsepower at high boost pressure levels and across the entire rpm range. Aerodynamics is what separates the GT-K turbo line from the competition. Equipped with the latest HP Compressor Wheels, designed to maximize efficiency at high boost pressures, and the F1 Turbine wheel, created to capture maximum exhaust gas energy and reduce back pressures, the GT-K family of turbos delivers unequalled performance. When paired with the Map Enhancement Porting of the GT-K compressor housings, these wheels flow huge volumes of air at high pressure ratios while still delivering a cool efficient intake charge. The F1 Turbines are a new generation of 10 bladed, tall tip height wheels that allow you to turn up the boost without encountering dreadful backpressure issues. Turbonetics exclusive Black-Chrome Perma-Coating also comes standard for heat reflection away from the compressor housing to aid it lowering compressor wheel inlet temperatures and gives these units great looks to match their performance. Select turbo systems will also be able to be upgraded to the GT-K Turbos if so desired. Turbine housings will feature high temperature ceramic coating to trap exhaust gas energy inside the turbine housing for greater energy delivery and faster response time, as well as keeping the engine compartment temperatures low. Cooler under hood temps means more power potential from a cooler compressor intake charge.
