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,

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