I took the top of my air box off last night to clean my K & N filter, took it for a drive with out it on and it was a bit louder. Is there any issues of running with out the top of the air box?

Dude, if you start with colder air coming in, your going to end with colder air. There's no aruging it. Having a cold air, even on a stock turbo is still benificial then a ram air.BLKDOUTSRT4 said:you honestly think that plastic lid will make a difference when the air is passing through a glowing red hot turbo ???? you see all kinds of race cars running filters over the tops of the turbo and thats it.....cant even count how many big turbo supras i have seen with just a screen over the turbo inside the engine bay
yes this is true, good point but the chances of you noticing a diference are exstreamly slim.rugdr said:im just a noob but i do know that colder air in a hot spot for the same amount of time than warmer air will be colder when it leaves. i.e turbo is 200 degrees and air going through is 80 for 1 second it comes out like 120. if the air going in is 70 degrees going in the same 200 degree turbo for 1 second it would be 110. then your ic is going to cool 110 degree air instead of 120 degree.
same as a microwave frozen pizza in for 10 minutes on high will be less done then a thawed pizza. and at times when it could be a 30 degree difference between air in hood vs outside air the difference is even bigger. now how much that will affect your performance is probably not enough to make a 5 car length difference in a race.
