VTT is hitting the ground running in 2023 with the F8X platforms. We are proud to introduce our “GCMAX” evolution of our insanely popular and record-holding GC Series of S55 turbocharger upgrades. We took what we learned from those, and take these to the next level! We increased all the internal flow channels, optimized AR ratios, maxed out the inlet size at 2.5″, and increased the compressor wheel to 67mm. Last but not least, the biggest difference maker! We had to completely retool our turbine housings to take our 54mm G25 series turbine. This wheel absolutely outflows everything on the market and is what we use on our G8X S58 GC+ and F9X M5/8 GC. This wheel is proven to spool faster and flow more than any other wheel in its size range. This is the KEY to making big power while keeping back pressure down. This same wheel combo has seen 1000WHP on the F9X platforms and has more still on top. This setup, also went 9.44@146 in the G80 with a completely stock motor, and drivetrain. If you are looking to take your F8X to the next level whether built motor or stock without breaking the bank, THIS is the ticket. Don’t mess around with overpriced slow spooling twins, or the hassle of going single, ending up with a laggy car, and hacked-up connections. These bolt-on like FACTORY. A plug, and play 1000WHP option!

Key Design Elements:

  • All new castings with larger flow channels, AR Ratio changes, and improved Aero over Current GC/GC+ housings
  • 310 Stainless Steel Turbine housing for the ultimate in heat, and corrosion resistance
  • 54mm G25 Spec 9 blade Superalloy Mar-M 246 turbine wheel with the latest aero technology for increased flow while maximizing spool
  • 67mm 9 blade “point-milled” compressor wheels with the latest aero technology to maximize flow while virtually eliminating surge
  • 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  set “GCMAX” turbochargers
  • 1- VTT set of “GCMAX” Silicone intakes

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 GCMAX with no other changes, to realize the full potential of the upgrade other parts/tune must be added.
