As one who drank the Koolaid, I would beg to disagree, IMO the Sam James
cowl intake area is WAY UNDERSIZED, I believe this has been
substantiated by another -10 builder who did some considerable
modifications to increase the size of the intake for the SJ cowl/plenum
and saw improved cooling performance. If you think about it, it stands
to reason, James uses the same size intake rings for the 6 cyl as he
does for the 4 cyl ????? Yet there is considerable more area to cool an
more heat generated. The cowls look sexy, but I cannot attribute ANY
improvement to speed/performance. However, by way of comparison there is
a Reduction in the cooling.

Considering the work that was done to develop the SamJames cowl and plenum...and how well they work - I think they're a great starting place.
