Taking the Mk3 Focus RS to (two) new levels - m450 and m520

The mountune m450 and m520 MRX upgrades replace the OE turbocharger with a Borg Warner series larger frame unit to deliver incredible power output with minimal increase in turbocharger lag, greatly enhancing the driving experience.
Tested and validated over thousands of miles and countless hours on the dyno for durability and performance, the m450 and m520 MRX turbocharger upgrade includes all required hardware, fittings and hoses needed for installation and is the perfect upgrade for customers already running either m400R or m400X.

Can't wait to see the figures for the m285 (Fiesta ST)! The m520 is shaping up to be a killer!

How does the RDU cope with 450hp

[@brandon8819]

In order to hit 500whp in these cars do you need a built motor?

[@darthpixelmc]

Yes, Mountune offer a forged engine kit that must be installed before getting the m520 kit.

[@15alex]

Sounds brilliant!! What type of exhaust is that???

[@mountuneofficial]

It's a mountune exhaust

[@visgrapablo5853]
