VTT-Cummins-GC-Composite-1

Description

Supported power level:

GC Stock-700WHP

Ready to take your 6.7 Cummins to the next level?  Don’t want to deal with core charges, long lead times, or restrictive factory housings? Look no further! VTT has you covered with our 100% new casting 6.7 Cummins “GC” turbocharger upgrade. We start by keeping the great design elements of the factory Cummins turbo and removing the not-so-great ones such as old school 12-blade turbine wheels, restrictive turbine housings, cast compressor wheels, Billet Cobalt VGT Nozzle for long life, and anything else we saw that could be improved upon.  Most people look at a turbo and think the compressor wheel is the key to making power. Bigger compressor more power right? Well, this is partly correct. In all honesty, the main factor for turbo flow is the turbine wheel size and design. Meaning blade count, blade design, aero, etc. Doing away with the 80’s tech 12-blade turbine, and going to an advance 9 blade wheel with enhanced aero, and cutouts to reduce weight and decrease spool time, you end up with a turbo that spools like stock, and has the potential to make 700WHP with the proper upgrades! With the basics covered, we stepped it up a level adding proprietary VTT changes and finished off by having all these parts cast to OE quality.  What this means for you is serious power for pulling, sledding, towing, or just a fast street made easy; GCs are a drop-in turbocharger upgrade that supports over 700 WHP while maintaining factory-like spool and all factory connections including oil, water, downpipe, and charge pipe.  Add our Max Flow Cast intake horn, Heater Grid Delete, Silicone  Charge pipes, or billet Valve cover to really get your 6.7-powered truck to the next level!

Key Design Elements:

• All new castings with factory restrictions removed. No oversized wheels stuffed into factory housings here!
• 70mm/62mm 9-blade Inconel turbine wheel with the VERY latest aero technology for increased flow while maximizing spool
• 90mm/64mm 9-blade “point-milled” compressor wheels with the latest aero technology to maximize flow while virtually eliminating surge
• Improved turbine housing AR Ratio
• Lower EGTS
• Billet Cobalt VGT Nozzle for increased life span, and trouble-free operation
• Direct connection to ALL factory lines including oil, water, downpipe, and factory charge pipe
• Redesigned, and improved internal components including bearing housing oiling, and an upgraded thrust bearing
• NO CORE CHARGES. The new unit is sold to you outright. Keep your old unit in case you ever want to go back to stock. Or sell it to recoup your investment -it’s up to you!
• No long lead times; once fully released production units will be on the shelf for same to next-day shipping (please inquire about stock levels when ordering)
• Full 12-month unlimited mileage/No Hassle Warranty. If you have an issue we will replace the unit no questions asked

Turbocharger Purchase includes:

• 1 – VTT Cummins  “GC” turbocharger

As with any turbocharger upgrade it should be coupled with complimenting upgrades such as fuel system upgrades, intake, downpipe, intercooler, tune, etc. While you will see gains going from stock turbo to a GC with no other changes, to realize the full potential of the upgrade other parts/tune must be added!

Be sure to grab a Cummins install kit to ensure a quick, and trouble-free install!

Every VTT turbocharger comes with a 1-year limited warranty. Please read our Warranty / Emissions Disclaimer when checking out for more details.
