ive been looking for an airbox for my sp2, and i realize the weight reduction is a part of the value to this mod, but what are the real gains made from the increased volume of air?
what i basically mean is most of the guys who install these airboxes gain about 4-7hp when they get it tuned, but how much of that gain is just from the custom tune itself. i havent seen one dyno sheet that shows a bike with the basic mods and custom dyno tune compared to simply installing the aftermarket airbox of choice and getting a re-tune. i had my bike custom tuned with akra slipons, k&n's, paired, deflapped, soft rev along with pcIII usb and gained 4rwhp and 2ft.lbs.
the next part of this question is how much does the stock airbox weigh without the rubber insulators on the outside? and how much do any of these aftermarket boxes weigh? so exactly what is your weight reduction with this mod?
and i know honda didnt waste their r&d money on developing this airbox to not be efficient, but would it be safe to assume that part of the design of this airbox were to meet epa standards of noise, etc... (much like the flapper). and if the idea is to increase volume, and reduce restriction of airflow couldnt you just cut out the front of the airbox and install a small screen and filter like all of these other airboxes and still make some gains? there would be some minimal weight loss, and minimal volume increase, and im sure a fair bit of airflow improvement.
so has anyone done a before and after dyno with just modifying the stock airbox in this manner? it seems the mori and squidskinz closed airbox for the sp2 is really an oversized stock airbox (much lighter as well) without the baffles, and filters so it would almost seem logical that there would be an improvement with the stock box if modified as i mentioned.
im looking to learn as much about this as possible before investing money on an airbox that could be potentially used in a better direction.
simplified, how much weight is lost with the aftermarket airboxes, how much real power is gained when comparing apples to apples (custom tune before and after) and what about a modified stock airbox dyno tuned before and after.
