NEW High Tech 71 Series Turbochargers
High Tech Turbo is proud to announce the new High Tech 71 Series. Our unique partnership with Borg Warner Turbo Systems prompts the evolution of our product line for 1991-2006 Dodge Cummins engines (adaptable to 1988-90 also). Along with Borg Warner’s race proven large shaft and our High Tech bearing and oiling system, these turbos combine the many improvements we have made since the inception of the HTB2 turbo line:
- Improved oil drain tube clearance.
- Our twin-ported wastegate now provides up to 50% more wastegate flow. This results in better boost control for single turbo applications as well as twin setups.
- Our adjustable boost pressure regulators utilize higher spring rates supporting higher pressures. These actuators employ our new "Easy-Adjust" feature.
- Borg Warner Low Drive Pressure turbine wheels. AKA, the “Killer Wheel” (71mm instead of the 65mm HTB2 wheel).
- Factory 1-Year warranty.
Big Power Diesel has utilized the HT, 71 series, Pro Street 66, to push trucks deep in to the 11 second range with amazing reliability. This is a very strong performing line of Turbos and is extremely robust.
The initial spool-up of these turbos might be slightly slower than out HTB2 series turbos but since the turbine wheels are low drive pressure design, they then build boost faster, offering you quicker acceleration.
These turbos should also provide a couple hundred degrees cooler EGT's under heavy acceleration and heavy loads like towing.
Like our HTB2 turbos, this series uses high torque, extended tip compressors = 62mm/87, 64mm/92, 66mm/96. (Alternate compressor sizes are for comparison to Garrett Powermax advertised compressor sizing.)
