MuchBoost N74 Upgraded Turbocharger with a Custom Billet Compressor Wheel and Clipped/Larger Turbine Wheel. It is based on an original BorgWarner Turbocharger, which means that the installation is 100%P&P. The turbocharger is meant to work with Rolls-Royce Ghost RR4/RR5 and BMW 760i F01/F02/F03 with the N74 – 544-570HP engines.

The turbo delivers up to 156% power (306 extra HP) over the factory specs. It is a great choice for someone looking for a bit extra HP from their daily driver. MuchBoost turbo allows you to get more from your engine and enjoy it even more than you’ve been so far.

We have developed 2 modification options that allow you to reach anywhere from 750HP to 850HP.

MuchBoost N74 750

Upgraded turbocharger with an estimated ~750HP at the crank. List of modifications:

  • Upgraded journal bearings system that allows the turbo to hold more boost,
  • More efficient and larger Billet Compressor Wheel,
  • Clipped and Lightened Turbine Wheel,
  • Genuine Garrett compressor housing,
  • Genuine Garrett bearing housing,
  • Genuine Garrett  exhaust manifold,
  • Original actuator,
  • Dynamically balanced,
  • The compressor and turbine wheels are balanced separately, and then the whole core is high-speed balanced using VSR balancing machines at speeds similar to the level seen in the vehicle.
MuchBoost N74 850

Upgraded turbocharger with an estimated potential of 850HP at the crank. Modifications compared to the 750 option are the same except:

  • Bigger Compressor Billet Wheel,
  • Bigger High-Flow Turbine Wheel.
Other significant modifications

In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.
