I had the password jdm power chamber for my GSR and it was definitly a waste of money...a lot of people think on their "butt dyno" that they got a lotta gain out of it..thats just becuase its so dam loud. I guarentee if i removed the top of someones stock airbox so they could hear their inktae that they would think their car is faster...thats just human nature. Look at real dynos for it. It makes 0 power and i could prove that compared to other intakes...if your looking for throttle response then it is actually a good intake but not for raw power...think about it...that intake is a replica of j's racing, and j's racing focuses on auto x rather than drag where throttle response is needed. So the asnwer is if u want to make the most power out of an intake take $140 and order a 3" short ram intake pipe and order a bpi flow stack kit with a velocity stack (

So go ahead and purchase the whale dick if u want good looks and throttle response but if your looking for gains that u will see on paper and on your timeslip...you cant beat a velocity stack on a 3" pipe.
