    • EVOMS Xona Rotor based McLaren MP4-12C & 650S M838T EVT825 & EVT825R hybrid turbo upgrades good for 800+ horsepower

      There are expensive McLaren M838T V8 upgrade options out there such as the $40k+ Hypercar Development system which adds a third turbocharger. Then there are upgrades that make sense such as EVOMS and their Xona Rotor based hybrid turbos.


      The EVOMS hybrid can propel you into the 9's at over 140 miles per hour and they actually have a slip to prove it.

      Since this is a hybrid upgrade you know it fits and it is a much easier/cleaner install as well as easier to tune than complicating things with an extra turbo:

Far more than a drop-in compressor wheel upgrade, these turbos completely replace the stock turbo center section with the latest technology in aerodynamics and ball bearings courtesy of Xona Rotor, ensuring reliable operation and no increase in turbo lag compared to stock. OEM compressor and turbine housings mean they are an easy bolt-on upgrade that, along with other components and crucially EVOMSit - Intelligent Tuning software, raise these super cars deep into hypercar territory at well over 800hp.
      EVT825 system starts at $25k which frankly in our opinion is still way overpriced for hybrid turbochargers.

      Pricing and dynos for the 825R system are not provided.


      Stock MP4-12C:

      • Wheel Power: 528 AWHP / 425 AWTQ All Stock
      • Engine Power: 621 HP / 500 TQ


      Test Car Baseline:

      • Wheel Power: 560 AWHP / 460AWTQ Fitted with High Flow Catalysts
      • Engine Power: 659 HP / 540TQ


      EVOMS EVT825:

      • Wheel Power: 705 AWHP / 600 AWTQ Fitted with EVOMS EVT825 Performance System
      • Engine Power: 829 HP / 705 TQ

        Overpriced, the mclaren turbos are just td04hl20t ! Old mitsu turbo 300$ each.

        Go instead with a pair of taiwanese drop in td04 upgrades for less than 1000$ and be done.

        Some BW EFR 7163 for the car are in the cooking too for a far better upgrade for less cost than evoms.

        I can not believe people are charging $25k+ for hybrids when you can do the drop in upgrade you just mentioned.

        Too good.

        People don't do their research, if mamba can profit with their 85$ stage 3 bearing I'm pretty sure turbo builder can get them for less than 50$ and make a 1000% profit on them selling as the revolutionnary upgrade.

        Best thing is you only have to machine the compressor housing.

        but you may contact them directly on FB, their were able to build me megane RS chra for stellar price. They can provide point milled compressors too but can't mimic the extreme tuners's one (yet).

        (for reference)

        If they can make vw and audi upgrades they can work something for porsche.

        The Extreme Tuners stuff looks awesome but I hear people questioning those guys and their reputability all the time.

        I don't see the 991.2 upgrades you were referencing but I'll keep looking. Would be amazing to already have a turbo upgrade option.

        No I don't think they have upgrade ready but they sure can make it possible without some bull$#@! 10+ month "research" aka turbo sitting on a shelf collecting dust waiting for financing.

        The 9a2 turbos are the classic vw/audi BW chra like golf GTi.
