Ok my friend has a g3 integra and the gasket around the throttle body connecting to the intake pipe broke so he just put the filter itself on the throttle body. now his car is a great deal louder, and a very sexy loudness at that (VERY deep and VERRRRY throaty).
i decided to take my intake pipe off and just put the filter on the throttle body too. my car accelerates faster up until about 4k - 4,200 rpm and after that it bogs down (doesnt accelerate nearly as fast).
i was thinking that because the filter is way back there the air it is getting is hotter so there isnt as much of it so the engine isnt getting enough air and thats why it bogs down. the cold air that comes up where the filter usually is will just be distributed around the engine bay now and lower the ambient temperature rather than getting sucked up by the intake.
the intake gets air faster because it doesnt have to go thru a pipe but its hotter air so i dunno… any suggestions?
You’re better off with a short ram or a CAI. Your getting insane amounts of heat soak with the filter sitting on top of the engine like that. Ugh. That’s super ricey.
i’d have to guess it’s not the heat that’s causing a problem, but the length of the pipe itself. intake arms are tuned to be a specefic length to get the air where it needs to go at a certain velocity. It seems like most any particular length will have a sweet spot. The factory or short-ram length is a pretty good compromise all the way up the rev range, but it sounds like with your set-up, you found the sweet spot to be below 4k.
anyway, yeah, get some kind of arm or something on there. and yeah, it might be hotter back there, causing lost power from that too.
Originally posted by XDEep wierd. i would have thought you would benefit in the high end and a pipe would benefit low end torque due to the increased velocity.
yea no kidding. short rams do better at high rpm than cai’s. maybe its really just soaking up waay too much heat. put a scoop in your hood dude!
hey! i thought i was the only one who tried that! hehehe, yea u lose plenty top end, as if the car just doesnt make any more power. After a while, i got sick of it, and put the stock air intake back in and left the bottom cover off, and it was alot stronger
