McLaren 650S EVOMS EVT855 Turbo Performance Package

The ultimate power package for the McLaren 650S delivers daily-drivable reliability capable of blistering 9-second quarter mile times.                                                                  

Evolution MotorSports' Turbo Performance Package for the McLaren 650S improves upon the already impressive stock engine horsepower and torque.  The stock 3.8L twin turbo engine with our EVT855 performance package is transformed to an impressive 855 HP and 720 lb. /ft. of TQ.  (Stock power as tested on our AWD Mustang 500SE dyno for the MP4-12C was 616 HP and 516 lb. /ft. of torque.) Our 100% “bolt-on” engine performance system upgrades the key engine components required to push the safe limits of the McLaren engine.  Our larger and more efficient turbochargers generate more airflow allowing the engine to unleash its full peak power potential. Our software remapping of the OEM Bosch MED17 ECU modifies the boost, ignition, fuel, torque limits, rev limits, launch control settings and many other parameters to create a safe and potent power upgrade that is second to none.

INCLUDES:

•   EVOMS Custom Garrett Turbochargers
  Provided on a core-exchange basis, these turbos are precision machined with custom internals, billet compressor wheels, and Garrett ball bearing center cartridges.
  
  
•   Fabspeed Motorsport Sport Catalytic Converters
  (EVT825S only) Fabspeed's performance Sport Cats utilize genuine HJS 300-cell catalysts designed and optimized specifically for street-driven McLaren applications.
  

•   Fabspeed Motorsport Catbypass Pipes
  (EVT855R only) Fabspeed's maximum performance Catbypass Pipes allow for unobstructed exhaust flow for competitive track and off-road use.
  
  
•   EVOMS Heat Defense Blankets
  Carbon/Kevlar blankets surround the exhaust manifolds and catalyst pipes to insulate the pipes and isolate the heat for sustained power increases.
  
  
•   Fabspeed Motorsport Supersport X-Pipe Exhaust
  Fabspeed's high-flowing X-Pipe rear exhaust complements the upgraded turbo system and provides an outstanding and aggressive exhaust note.
  
  
•   EVOMSit EVT855 ECU Software Calibration
  Evolution Motorsport's custom ECU software calibration optimizes the vehicle's operating parameters to take full advantage of the upgraded components.

FEATURES:

The heart of the Evolution Motorsports' engine upgrades for the McLaren 650S 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.

PRODUCT HIGHLIGHTS:

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”.

Exhaust Header & Catalyst Pipe Heat Defense Blankets
The final piece to the equation is our Heat Defense Blankets for the OEM exhaust manifolds and upgraded high flow catalyst pipes.  Our 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.  Our 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.
