Injector Dynamics Fuel Injectors for McLaren

McLaren's twin-turbo V8 platform is one of the most potent forced induction engines in production — and it responds dramatically to tuning. From the MP4-12C through to the 720S, Senna, and P1, McLaren owners chasing more power need fuel injectors that can support significantly higher fuel demand while maintaining the drivability and refinement these cars are built for. Injector Dynamics offers precisely characterised, dynamically matched fuel injectors with direct plug-and-play fitment across the full McLaren range.

McLaren MP4-12C / 570S / 600LT / 650S / 675LT

The M838T 3.8-litre twin-turbo V8 powers the MP4-12C, 570S, 600LT, 650S, and 675LT. These engines are already making serious power from factory — the 675LT produces over 500kW — and tuned examples with upgraded turbos, downpipes, and ECU calibration regularly push well beyond 600kW. The factory injectors cannot support these power levels, particularly on E85 where fuel demand increases by 30 to 40%.

A set of eight Injector Dynamics ID1050x injectors supports approximately 640 to 880kW at the crank on petrol at 80% duty cycle — covering the majority of tuned McLaren builds. On E85, eight ID1050x injectors support up to approximately 440 to 640kW. For builds pushing beyond those numbers, the ID1300x and ID1750x provide additional flow headroom.

Select your specific model when ordering — MP4-12C, 570S, 600LT, 650S, or 675LT.

McLaren 720S

The M840T 4.0-litre twin-turbo V8 in the 720S is one of the most powerful production engines available. Factory output already exceeds 530kW, and tuned 720S builds with upgraded turbos and fuelling regularly exceed 750kW. Upgraded injectors are essential at these power levels.

A set of eight ID1050x injectors provides ample flow for moderate 720S power increases on petrol. For the serious power levels most tuned 720S builds target, the ID1300x (supporting approximately 800 to 1,080kW on petrol across eight cylinders) is the more common choice. Select "720S" when ordering.

McLaren P1 / Senna

The P1 and Senna represent the pinnacle of McLaren's engineering. While fewer of these cars are modified, owners who do push beyond factory power levels need injectors that can deliver the fuel volume required without compromising the precision and refinement these cars demand.

ID injectors are available in direct-fit configurations for both the P1 and Senna. Select your model when ordering.

Why Injector Dynamics for McLaren?

On a high-value platform like McLaren, drivability and refinement are non-negotiable. Injector Dynamics' complete characterisation data — dynamic slope flow rates, dead time values across voltage and pressure ranges, and dynamic flow matching across all eight cylinders — ensures your tuner can calibrate the ECU for seamless power delivery, smooth idle, and clean throttle transitions. There is no compromise in daily drivability to achieve higher peak power.

Every set ships with data compatible with all major ECU platforms including Haltech, MoTeC, and EcuTek. All ID injectors are fully compatible with petrol, E85, E100, and methanol with corrosion-resistant stainless steel internals.
