Nerd’s Eye View: SEMA 2014 Part II

,

Ford has gone all-in on turbocharged and direct injection gasoline engines with an Ecoboost engine being offered in everything they make. mountune, a name long known in Europe is now making its presence known the in the US. Here is the 2.0L Ford Ecoboost engine with a few mountune upgrades.
The OEMs have gotten very good at taking up all the available space in engine bays. Here you can see just how severe of a bend the exhaust gas makes in going from the head integrated exhaust manifold into the turbine housing of the turbocharger. A heat shield protects the water lines from the heat coming off the turbine housing.
Did I mention that underhood space was at a premium? It is now common practice to place the turbo on the backside of a transverse engine up against the rear firewall of the engine bay. This allows for close placement of the catalytic converter for quick light-off and lower emissions. It might be to help with weight distribution too. Anyway, this creates a challenge in routing the air into and out of the turbo. Ford chose to go under the engine for the compressor discharge pipe by making an indentation in the oil pan to clear a path. On a side note, notice the flexible turbo oil drain line to allow for movement between the turbo and block and thermal expansion and all that good stuff.
The compressor discharge pipe works its way forward and connects to the mountune front mount IC connected by the mountune hose. On the far side of the IC, you can see the other mountune hose going vertical into the throttle body.
Cutaways are awesome as they allow us to see the inner workings of parts. Magnuson Superchargers had this cutaway of a blower setup for APR. That is not a simple casting! Anyway, you can see how the air enters from the throttle body on the left and enters the screws of the blower. The air is discharged from the screws out the middle and top where it flows to the two air-to-water IC cores before going into the engine.
