Banks developed the Quick-Turbo in conjunction with the Holset turbocharger and Cummins Engine companies, to eliminate sluggishness out of the hole and produce strong acceleration. Quick-Turbo produces massive torque right from idle, achieves a higher peak faster, maintains more boost through the powerband, and doesn't over-boost. Add Banks exclusive BigHead wastegate actuator to prevent wastegate blow-open by keeping the valve seated at higher pressures, increasing mid-range torque and top-end power. Also add Banks high-boost compressor wheel to correct boost-level limits in late 1999.5-2003 models, built for higher boost levels without compromising turbo performance. Key Features: Maximizes turbo-diesel efficiency. Provides massive instantaneous torque. Eliminates backpressure. Maximizes boost. Eliminates turbo lag
