Noticable improvement with cut airboxes?
I figure I'm going to cut off the bottoms of my airboxes in my 90 Iroc-Z 5.7 until I have some xtra cash for a nice looking intake setup that'll also function better.
Anyway - I know tons of you guys have done this, did it make you happy or was it a 'I know it's working but I cant feel it mod'?

As for gains from cutting the airboxes. Yes, it is one of those things that you don't really feel, you just do it because you are supposed to and everybody else does.

I don't have any timeslip comparos or dynos, but I cutout the bottom of my airboxes and put in 2 6" round a/c duct elbows and used aluminum tape to "seal" up the airbox to the elbows. Seems to have worked fine so far.

I got 2 tenths in the quarter when I did it to my stock engine.
Maybe the weather was different or something, but one week I ran a 15.00 and the next it was a 14.80. Can't argue with results...especially the free kind.

if you pull out the entire air box and look underneath, it doesn't look like there's any "holes" for the air to flow into the area underneath it. so cutting out the bottom of the airbox probably won't do anything signifigant unless you somehow route the air to it.
didn't stop me from doing it though...

I looked in the boxes, and theres no openings... I figure with the bottoms off the filters can suck more from other spaces around the boxes. I'm not familiar with the Camaros 'empty places' in the nose... I used to have a firebird.
Right im not gonna change the stock intake... I remember reading on the boards it'll hold for 12 second cars easy... and i'm not going into 12's.

I think if anything it cant hurt at all.
Now, I am almost sure that it will help, cause the only change that could occur is more air for the filters to suck up.
To make a third point, if I feel motivated one day, the ram air to the fog lights housing will certainly only improve it more.
Im totally going to do this. Decision made, 19 year old happy. Good work boys, clock out and go home to your wives =).
