Nerd’s Eye View: SEMA 2013 – Part II



This here little engine in the Banks booth is a potential game changer. It’s a 3.0L V6 diesel coming in the Dodge Ram that is rated at around 240hp and 420 lb-ft of torque.
That’s a little Honeywell Turbo with a VNT. You can see the electronic actuator bolted to the compressor side of the turbo (it’s cooler than the turbine side of course) with the rod going to the crank to control the vanes in the turbine side. Heat shielding is used on the turbine housing along with the exhaust pipes going from the manifolds to the turbo. Remember, heat shielding is a key to being reliable.
Of course, the OEMs use exhaust bellows to allow for thermal expansion and contraction to maximize reliability.
What’s this? A NACA duct on the hood used as a cold air intake on a Fiat 500? I guess my cold-air/ram-air NACA duct idea for my S2000 wasn’t so half baked after all as someone else had the same idea. Also, the cutout on the other side of the hood has a raised carbon fiber lip on the leading edge and sides of the hole to help pull air out of the engine bay.
The NACA duct feeds this other duct. FYI, the sticker on the back of the NACA duct says, “Abarth Trofeo”.
