The McLaren M840T is a 4.0 liter, Twin Turbo, flat plane V8 engine that powers the 720s, Senna, GT, Speedtail exotic sports cars. Released in 2017, this is the latest upgrade to the 3.8 liter M380T found in older models like the 650s. Even further back, the engine carries residual DNA of a LeMans Nissan Engine and turbos from a Mitsubishi EVO.
After it’s launch, the 720s quickly became popular amongst tuners, sharing drag strips with the likes of Nissan GT-R’s and Audi R8s, yet claiming a lane for itself with an identifiable exhaust note. We started testing the limits and set the benchmark with the world’s first McLaren 720s to break the 200mph barrier with a record pass of 14.76 seconds @ 202.15 mph in the standing half mile and 22.93 seconds @ 227.99 mph in the standing 1 mile.
As others enthusiasts began to modify and upgrade their McLarens, Infinit Performance began getting calls for repairs and upgrades across the globe. McLaren did not offer replacement parts at the time and customers requested increased loads of over 1500 hp to be placed on the engine. Post mortems revealed the engines were suffering from excessive oil consumption, early failure and bent connecting rods – and a need for replacement McLaren Parts.
