I'm unsure how to mate the 90mm to the engine intake. Securing the air intake is another concern.
The other side is that if the engine intake is only 74mm then what benefits will there be to trying to force a 90mm to mate to it?
Things I need to work out; quite new to this side of things - mechanics I'm not new too, but usually following others instructions/steps.
The answers that you seek can be found by studying volumetric efficiency and head flow rates and the tool that will help you achieve those answers is called a cylinder head flow bench. Any engine builder worth their salt knows the biggest power gains are found in the head and the components that make it work. The Mercedes engineers we're not that tight lipped when
they gave you the best suggestion they could, change the cam profile ! more lift and a longer duration equals more power. The bottom line is the horsepower you gain is directly proportional to the Limit of your finances and the physical limits of the m112.
