if i take the airbox off will it cause any problems or reduce in mpg?

[chevyman2013]

do all regal gs's have the performance shift?

@chevyman2013 From like 97-99 there was a button on the shifter and in the later years it went to performance shift automatically when you went WOT.

[chevyman2013]

@KFCOrBust oh well thats cool. im getting a regal like in a week so im looking forward to seeing how it works

[regalgsme]

urbody asks me the same thing cuz i got cold air intake and that supercharger screams, but i got strate pipes with a flowmaster, intercooled, smaller SC pulley, camed, and all that good shit, runs 0 to 60 in 3.8 sec

What's that noise besides the exhaust ???

[KFCOrBust]

@badbarada Uh, the supercharger. No exhaust sound, it's stock, you're just hearing the engine.

@KFCOrBust

OK!!! I have the same problem on my GS. I thought something was wrong with my supercharger but i believe that all superchargers make this crappy noise. LOL :D

[KFCOrBust]

@badbarada It's not a problem, it's what's supposed to happen when the airflow to the supercharger isn't restricted by the stock air box. All roots blowers sound like this.
