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", increased the compressor wheel to 67mm. Last but not least, the biggest difference make! 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 the hassle of going single, and ending up with a laggy car, and hacked-up connections. These bolt-on like FACTORY. A plug, and play 1000WHP option!
