AWeb80 Posted August 11, 2003 Report Share Posted August 11, 2003 I drilled 12 1/2" holes in my airbox toward the front of the car and on the side toward the battery. I didn't notice any gain upto 2800 rpm's, but from 3,000 to the redline, that baby humms and I did notice a little increase in power. I love the noise it makes in the interior of the car. I'd recommend this to everyone. 8) 8) 8) Quote Link to comment Share on other sites More sharing options...

Brian P Posted August 12, 2003 Report Share Posted August 12, 2003 yous peoples are weird. Don't be fooled by the extra growl and the powerband change, your cars aren't going any faster, at least the 3.1's. Ive done too many tests and runs at the track to know this Quote Link to comment Share on other sites More sharing options...

jpv123 Posted August 13, 2003 Report Share Posted August 13, 2003 I just joined the "HOLE IN THE BOX" Club 10 minutes ago. Love that sound! Quote Link to comment Share on other sites More sharing options...
RomeoZ34 Posted August 13, 2003 Report Share Posted August 13, 2003 It may sound cool, but it will look ultra ghetto when you pop the hood. Just save the cash and buy a CAI or HAI and do it the right way. Quote Link to comment Share on other sites More sharing options...
topless94style Posted August 13, 2003 Report Share Posted August 13, 2003 Id doesnt look "ultra ghetto" when u drill the holes on the bottom and the battery side of the box. Quote Link to comment Share on other sites More sharing options...
jpv123 Posted August 13, 2003 Report Share Posted August 13, 2003 I drilled the smaller holes, and when done neatly, you can't see it unless you really look for it. Quote Link to comment Share on other sites More sharing options...
Mike J. Posted August 13, 2003 Report Share Posted August 13, 2003 Can't you just remove the removeable front cone which will make a large opening now and will let out lots of sound ???????? Do the later air boxes have a removeable front cone like the 88-93-(or so) ??? Quote Link to comment Share on other sites More sharing options...
topless94style Posted August 13, 2003 Report Share Posted August 13, 2003 My 94 has a decent size one but i just drilled holes in the bottom and along the bottom of the sides because it seemed easier than trying to take out the front cone and dealing with not breaking the plastic. I dont need it breaking and not looking good. I used prolyl 1/4" drill bit maybe smaller and drilled prolly 20-30 holes total adds more sound and better throttle response and maybe this is a mind thing but more high end power.

Mike J. Posted August 13, 2003 Report Share Posted August 13, 2003 On my 92 DOHC GP the cone simply slips in and out by hand. Aren't they all this way ? :?: If you have a free-er breathing DOHC, you can probably feel some gains if you remove some restriction. Mine had a defective/scrunched halfway closed cone, and when I took it out, I Definitely sensed it had more upper rpm pull. Quote Link to comment Share on other sites More sharing options...
topless94style Posted August 13, 2003 Report Share Posted August 13, 2003 Yea i can feel more upper rpm gain. My cone looks like it would be harder to remove than drill a bunch of holes but thats just because im lazy. Ill try someday. Quote Link to comment Share on other sites More sharing options...
