Nerd’s Eye View: 2012 LA Auto Show

,

I’m not exactly sure what this tube is but it appears to go from the coolant circuit and pops into the intake manifold.  I guess it’s like running coolant lines to the throttle body to help with cold-starts.  Someone correct me if I’m wrong.

 

Toyota had a really big presence at the show this year including a large Motorsports section.  This is their NASCAR setup on display.  Check out the size of the radiators!  You need massive ones when the car spends all day in a draft with greatly reduced airflow.  

 

A look at the bottom-end shows some details.  The pistons look like they have a coating on the skirts to reduce friction.  Chuck can chime in on the piston and ring design if he reads this.  The oil pan looks to have some baffles integrated.  Those baffles might be used to reduce windage between the cylinders to improve power.  The exhaust manifold uses stepped primaries; each step in the primary causes a refractive wave and this design is used to tune the header for a wider powerband.  F1 cars use the same technique of stepped primaries.

 

Those are some pretty headers!  Here you can see the stepped primaries again along with the super nice merge collectors for optimum flow.

 

The top-end uses these really beefy pushrods and rocker assemblies that can survive 10,000 rpms.
