what if i drive around with the lid off my air box
like the title says, what if i drive around with the lid off, it makes the spool sounds soooooooooooooooo goooooooood and the diverter valve sounds amazing! but my buddy says its really bad for it, is he right?

If the air is bypassing the filter with the lid off, of course it's bad for it. But if your air is still being filtered, it shouldn't be a problem (until it starts to rain).
But then again, I may be totally wrong. :)

i have been curious to see how this effects the fuel trims. is taking the lid off letting more air in, or less air? if the lid is off the box is no longer pressurized per say so exactly how does that effect the airflow? the stock ecm is only calibrated for stock so either way the fuel trims would be effected i would think. i have never seen actual data posted for this.

Sounds good huh?? It is close to what "moon" did just using warmer air, folks say my intercooler is too big anyway. If its not throwing codes it is prolly sucking close to the same air. Moon said you can hear the BOV a block away was he exaggerating or not ?

one thing i have learned with this car is things can be very wrong and not throw a code. right now i have a boost leak...no code. my fuel trims are +/- 20% as a result and still no code. i am running so lean it is dangerous....still no code. that is why i ask.
what intercooler are you running? and without the muffling and restriction of the stock intake box, the turbo whistle and the bypass valve are very audible. a block...maybe not but probably pretty close if it was real quiet outside.

yeah im not sure if that's what im trying to say but cram air through the tube in the fenderwell into the airbox with the lid closed and there is in my theory more of a suction going on...take the lid off the box and it is trying to suck the air from two different places...or maybe just the one that provides more air....im not sure....that's part of what i think has not been determined.

Guess we will have to wait to see what ChevySSguy says when he gets back from driving it around. It would be handy to have a Aeroforce on it to ask. Maybe Asanti will try it both ways and tell us how it comes out.
