I just took off my airbox lid off and it sounds awesome Havent really drove it hard yet but did you feel any differences? I think ill stick to this until I get a intake and tune.

 

Not sure about performance gains for taking off the stock lid on the airbox. In fact, it might hurt performance to take off the stock lid because the engine will suck in more hot air. I took my lid off for the bling factor so the BOV is louder. However, i didn't notice any performance losses by taking off the stock lid according to my butt dyno.

 

Without the airbox cover, there was less low end torque, and I had to rev a bit more just to launch the car. Definitelly some power loss without the cover, but you can hear the bov whoosh sound though. I just got a used gfb and have it set to vent a little and so far its good enough to satisfy my rice needs.

 

whats gfb?

 

BTW wasnt there a thread about Buschur doing a dyno test with some parts and if im not mistaken he did mention taking off the airbox lid on the dyno. But not sure if he got any gains or not.

 

GFB = Go Fast Bits dual vent BOV

It allows you to partially vent to atm and partially recirculate.

what is the Fudge factor?

 

I thought hot air going into turbo cars dont affect the turbo?

 

hope not, mine has been off for a while...

how much are you guys paying for your k&n filters? the local pep boys has them for 75, is that a straight price?

 

Does the filter get dirty fast with the airbox lid off?

 

The filter does get dirty fast. I have the K&N drop in too. I want to take off the cover but my ECU is tuned to it. So I would start to run to lean My friend has the ARC intake. Pretty cool.

 

I agree, the filter will get dirty very fast, not really worth it. After driving it for a day I notice a slight power loss in higher rpm. Not sure if its sucking in too much air or what but somehow it doesnt have as much torque. I decided to put it back on and just wait for a intake with tune. BTW is was fun hearing the stock BOV
