No. It did not. It was simply filter drag. Induction path wasn't part of the test.

Walter,
Did your flow tests include a 90 degree turn with the entrance losses associated with us updraft carb types ?? It was the return to laminar flow that suported Vans' data.. Thx for the interest... Don Skeele

FWIW, I ran a test.
1) MP measured with NO FILTER AT ALL.
2) MP measured with paper filter.
3) MP measured with bracket filter
4) MP measured with K&N filter.
They resulted in the following order of MP, from highest to lowest:
NO filter, PAPER filter, K&N filter, BRACKET filter. The two middle ones
were very close to the same--frankly, too close to call as being any
different.
YMMV.
