The McLaren M838T 3.8-liter twin-turbocharged V8 is one of the most capable engine platforms in the supercar world — and it powers more McLaren models than any other engine in the company's history. Found in the 570S, 570GT, 540C, 600LT, 650S, and MP4-12C, the M838T responds to ECU calibration with gains that transform these already rapid supercars into genuinely terrifying machines. A Stage 2 tune on the 570S delivers 680 HP from an engine rated at 562 HP from the factory — and the 650S responds with similar aggression. This guide covers everything you need to know about ECU tuning...

Why Convert Your McLaren 570S to a Longtail? The McLaren 570S is the most accessible supercar in the McLaren lineup — and the most popular platform for owners who want track-level aggression without selling a kidney for a 600LT. The longtail design language represents everything McLaren does best: lower drag, higher downforce, and a visual stance that separates your car from every other Sport Series on the road. The YPG Longtail Aero Kit is a complete bolt-on carbon fiber body conversion that transforms any 570S, 570GT, or 540C into a longtail-inspired machine — with a performance exhaust included in the...

The McLaren 720S is powered by the M840T — a 4.0-litre twin-turbo flat-plane-crank V8 that produces 710 HP from the factory. It is one of the most technologically advanced engines in any production car, and it has significant untapped performance potential. The factory catalytic converters, positioned downstream of each turbocharger, are the single biggest restriction in the exhaust system. Replacing them with performance downpipes is the foundation of serious 720S power builds. The M840T Exhaust Architecture McLaren’s M840T is a bespoke unit — not shared with any other manufacturer. The flat-plane crankshaft delivers an even firing order that naturally produces...
