Description

McLaren M838T 3.8L Twin Turbocharged V8 Engine


The Weistec W.3 Turbo Upgrade for the McLaren MP4-12C, 570, 650, and 675LT Series vehicles provides vastly improved top end performance of the 3.8L twin turbo M838T Engine.  Where the factory turbos peak out shortly after 6000 rpm causing power to drop as revs increase towards 8000 rpm, the Weistec W.3 Turbos hold power until the rev limiter.

The factory turbocharges are disassembled and fully inspected.  The compressor cover and center cartridge are then machined to accept our 5-axis CNC machined impeller wheel which despite being substantially larger, weighs the same as the factory cast impeller wheel.  Externally, no changes are made to maintain a completely stock appearance.  The new impeller wheel supports greater power levels than the factory unit with little to no sacrifice in spool and response thanks to its light weight construction.  The turbochargers are then reassembled with new seals and bearings, then fully balanced for smooth operation and OEM service life.  All the OEM oil and coolant lines bolt right up making for a simple install.

For maximum results, the combination of our Weistec Downpipes, and Weistec High Flow Air Filters is recommended.  A Weistec W.3 Turbo Specific ECU Upgrade is recommended.
