But when you are actually measuring the ram effect, you MUST only measure real world conditions, because the ram effect is all about the change in air pressure with speed. If you can't replicate that on a dyno with suitable high-powered fans, then you may as well use your "butt dyno" to guess what is working and what isn't.
