Here's a pic of mine when I had it on this winter. I also used the ZTEC heat shield with it.
I personally think it looked great in the car and sounded great. I couldn't tell if there was any heat soak because the intake was on during the winter. Anyways that was my $0.02.
I think it's just plain common sense that length and diameter of piping will affect C.F.M. of airflow. Bigger diameter or shorter tube flows better than longer or narrower tube. What the cold air intakes lack in C.F.M. of airflow they make up for in cooler air intake temps. and denser air which makes a more powerful combustion and more power. However if the diameter of the throttle body is unchanged you will reach a point to where increased pipe diameter ceases to make a difference in airflow rate. The name of this thread is "Who has the Weapon - R intake?" I took this as . . . . owners of the Weapon - R intake tell me about your thoughts about this intake. NO AFTERMARKET INTAKE will give substantial gains on the S2000. What's the point of arguing over 1-3 H.P. differences? I say make up your own mind based on price, looks, cost, sound, accessibility, personal car use, climate ect.
Ohms law? Time to take a breather there. Ohms law and other electrical theory has next to nothing to do with aero and or hydrodynamics. Those are the things you need to concern yourself with when dealing with the flow of gas or liquid through a pipe.
No question a bigger tube flows more air, but it's also the velocity of that air that matters. Same reason a longer barrel rifle has a higher muzzle velocity than a handgun. Just because the tube is short doesn't mean you're going to get better gains from it. In the realm of gas through a pipe, there are resonances and pulses that need to be engineered for which AEM does quite well. Comptech does too with their big bulge in the intake tubing; that's all done to enhance and capitalize on resonances. Small short tubes don't guarantee anything when dealing with the intake tract of this motor.
