Concurr with Steve & Claudete Colwell comments on the VanA/C Carb intake.
I had gone over Van's test data with their then Chief Engineer, Steve
Smith which did show about an inch or so improvement in MP with the K & N
Filter in place vs MP without the filter installed.  They reasoned that
the filter resulted in a smoother transition as the air turned up in to
the carb throat, in that the circular filter reduced the turbulance, and
therefore the pressure loss.  I had to lower the bottom half of the air
scoop 5/8" to accomodate the larger Van Design..I cut the entire cowl
off horizontally to add the 5/8" which gave a greater exit area for the
induction cooling also, and no heating problems at any configueration.
Does it work ? the A/C has won the Redmond Race for Modified 235's four of
the last 5 years.
