MACHGRADE Hybrid Turbocharger. The production of the MACHGRADE 550 option starts with a stock genuine KKK turbocharger, and the main upgrade consists of a bigger, custom CNC billet compressor wheel with 6+6 blades.  The unit keeps the original turbine wheel (exhaust, hot side) and OEM bearing solution, which comes with the advantage of an insignificant increase of lag. The turbo is optimized to deliver 550HP, and it’s fully Plug&Play. The more extreme version for 600HP has upgraded hot side, which allows for a better flow of exhaust gases, but it’s not fully P&P as oil and cooling lines have to be custom. Both versions fit Mercedes models equipped with M139 engines like A45S, CLA45S and GLA45S.

Process of building of the turbo
