MuchBoost S55 3.0 Twin-turbo Upgraded Turbochargers with a Custom Billet Compressor Wheel and Enlarged Turbine Wheel. They are based on original Mitsubishi turbochargers which means that the installation is 100%P&P. The turbochargers are meant to work with BMW M3, M4 with S55B30 431HP engines.

The turbo delivers up to 162% (269HP extra) of power over the factory specs. It will make your car feel even faster and the power will be a lot more intense. 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 680HP to +700HP.

MuchBoost S55 680

Upgraded turbochargers with an estimated ~680HP at the crank. List of modifications:

  • Precisely machined seal plates and compressor housing,
  • Genuine Mitshubishi compressor housing,
  • Genuine Mitshubishi bearing housing,
  • Genuine Mitsubishi exhaust manifold,
  • Upgraded journal bearings system that allows the turbo to hold more boost,
  • More efficient and larger Billet Compressor Wheel 11+0 blades,
  • Enlarged High-Flow 10 Blades Turbine Wheel,
  • Precisely machined turbine housing,
  • 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.
