Anyone running a airbox with no lid

I just picked up my SS on Tuesday and today I ran the car with out the airbox lid. As stated above IAT's went up a bit. Outside ambient temp was -2C. With the lid on IAT's stayed at 0C to 2C while in motion in city traffic and never went above 6C at stop lights. Took it home pulled the lid and drove the same route. IAT's were 1C to 4C while in motion and Highest I saw at a stop light was 8C.
Not a huge difference IMO. Maybe in the summer when Outside Ambient temps get up above 30C I would put the lid back on. But the difference in the temps during the colder weather are not that bad IMO. Car felt the same power wise both ways and sounded much better with the lid off.
P.S sorry for bringing back an old thread along with beating a dead horse =P

I just tried this, and it does sound nice 
Lots more wooshing and whistling, although I was hoping for a bit more induction growl. It must be pretty loud outside the car because it sure turns heads when I shift at redline
I talked to Vince at Trifecta about this, and he doesn't think the intake temperature difference is significant, but that it can skew the airflow readings slightly and may require a tuning tweak.

its a damn shame that the hood stiffners are right over the air-box, otherwise an offset baffled scoop and some thick weather stripping would be really nice, if you can deal with the 90's euro look IMO.

Again..you are explaining air AFTER the turbo..not before...you are talking mechanically pressurized air and I am talking static atmospheric pressured air..I have no problem relating to what you say..you are correct, on the pressurized side of the turbo( exit). The entry side of the turbo will encounter the same problems as a normally aspirated motor as far as intake tubes and restrictions are concerned..you cannot magically produce ( yes..volume) so many cubes of pressurized air UNLESS your supply side allows it,,
Heres my example- simple central attic fan..turn it on with alll the windows closed and note the fan speed( read load) now open a few windows ans see how much faster the fan turns because NOW you have an ample amout of air to move and the fan is allowd to operate at max compacity..a restrictive intake tube willl do the same...must be an engineer

However, it's important to make sure that this threshold is reached. Once the threshold (i.e. lack of restriction) is met the only way to improve on things is to get a bigger turbo or some other way of "creating" more flow through the engine itself.
