Thread: Cold air intake system

Bill, you think like I do, cobbling something up from inexpensive parts that works. Your filter size was real close to being right in my opinion, 144 sq. in. Bigger is better when it comes to filters.

It's a fact that for each 10 degree drop in air temperature going into the motor, the motor will pick up 1% power, assuming of course that fuel delivery is enriched at the same time to allow the proper a/f ratio.

If the vehicle already picks up ambient air from outside the engine bay, then you're not going to gain much with a different filter and ducting, but if the filter is picking up air from within the engine bay, then changing the system to pick up ambient air will improve power.

I just have to laugh to myself and turn away when I see these ricer guys at the dragstrip who have spent megabucks for aftermarket piping and a K & N filter arrangement and then terminate the filter right behind the radiator in the engine bay. Just another case of monkey-see, monkey-do without thinking the whole thing through. It's like the first guy who cobbled up a system for sale made it all wrong and everyone else followed his lead. HAHAHAHAHAHAHA.
