Intake testing method
Hi all,
I've found that HP gains are hard to measure in CA, due to crappy gas. So in data logging some stuff, one can look at graphs like this

to see how well intakes preform. The lower group of lines is the upstream manifold pressure, and a blow up of it is shown here

The drop in pressure is due to flow restrictions in the intake path. While we all want to know HP improvements, this is an easier test to make quantitative.
FWIW....
