NEW RELEASE |  EVOMS EVT825S/EVT855R McLaren Turbo Packages


The heart of the Evolution Motorsports' engine upgrades for the McLaren MP4-12C is a complete performance system that has been designed from the ground up with individual components engineered to work as a complete kit. All of our individual products were developed with the end power goal in mind. This allows trouble-free staged upgrades as your appetite for more power increases. All of our upgrade stages seamlessly integrate individually or as a complete performance system to improve the power and torque of the twin-turbocharged McLaren 3.8L engine.


Billet Wheel Ball Bearing High Flow Turbochargers |  EVOMS' upgraded turbochargers were engineered to be a true “bolt-on” upgrade, even though they contain many upgraded internal parts. Evo has completely gutted the OEM Mitsubishi TD04 turbos and fitted Garrett center sections with ball bearings, a custom turbine, and a billet compressor wheel. The ball bearing turbocharger upgrade is more efficient than stock, capable of up to 950hp while spooling up at lower RPM and with better response than the smaller OEM turbos. Evo undertook painstaking efforts to deliver an easy and trouble-free installation. The turbos are a direct replacement and bolt up to the OEM header and catalyst pipes. The OEM oil and water supplies mate up correctly as well using the supplied hardware.

Fabspeed Motorsport Exhaust Components |  Hand-crafted T304L stainless steel German-made HJS 200-cell high flow catalysts significantly reduce engine back pressure and exhaust gas temperatures (EGT’s) which enable the turbochargers and engine to operate more efficiently. These high flow cat pipes are made from mandrel-bent stainless steel and are a direct replacement for the OEM catalysts. The exhaust notes with the free flowing exhaust system with quad tips further enhances the already intoxicating engine sound without any obnoxious exhaust “bark”.

  • (EVT825S only) Fabspeed's performance Sport Cats utilize genuine HJS 300-cell catalysts designed and optimized specifically for street-driven McLaren applications.

Exhaust Header & Catalyst Pipe Heat Defense Blankets  |  The final piece to the equation is Heat Defense Blankets for the OEM exhaust manifolds and upgraded high flow catalyst pipes. EvoMS custom-made heat blankets are made in the USA from the highest grade Carbon/Kevlar materials to dramatically reduce exhaust heat radiated into the engine bay. Exhaust heat has a significant impact on the performance of the McLaren’s intercoolers, which are positioned next to the exhaust and become quickly heat soaked due to their close proximity. Hot intercoolers are less effective at cooling the boosted air from the turbos, resulting in higher intake temperatures and less power. Heat blankets reduce heat transfer between the exhaust, intercoolers, and surrounding components, improving intercooler efficiency for more consistent power delivery. The exhaust manifold blankets are designed to allow the OEM heat shields to be installed over top of them, providing a double-layered heat defense. The net effect is lower engine bay temperatures which equates to higher and more consistent power delivery.

EVOMSit ECU Recalibration  |  Extracting the maximum and safe performance of the McLaren 3.8L V8 Twin turbo engine is hidden within the OEM ECU. To unleash the full power potential requires modifying the OEM Bosch MED17 ECU with our EVOMSit software Recalibration. Having access to and being able to modify the boost, ignition, fuel, TQ limits, rev limits, launch control settings and many other parameters allows us to create a safe and potent power upgrade that is second to none. Countless hours’ dyno and real world testing the McLaren has allowed us to achieve unparalleled results.
