i have an 07 wrx got catback sti intercooler and the stage 1 map for the ap. i was getting on the free way and i hit about 100 and i started hearing a weird humming and as i increased my speed the noise got louder. what could it be .has anyone else had this happen to them?

 

I have....if you search threads for it, apparently it is normal... caused by the wind hitting the car at high speeds..

 

110 or higher starts to humm pretty loud. Just air moving over the car or through the scoop and off the fenders I guess. Our car arent really built like airplanes!

 

hey thanks i was freakin out.

 

so what can be done about this? i have the same problem in my 05 sti. at 110 plus it starts, and by 140 its obnoxious! possibly roof fins?

 

very good question??? it is really starting to **** me off. ..... i mean i know leagal speed limit is not 110 or higher but comeon you gotta have some fun

 

anyone??? i need the guru's here. what can i possibly do to stop the high speed humming? (other than slow down)

 

Are you sure it's not coming out of your speakers?

 

yea im sure after 110 its crazy its not the speakers for sure

 

If you fold your mirrors in, it should stop.

 

Be careful smashing on the FWY like that

 

My 06 wrx wagon does the same thing. It starts anywhere from 90- 100+. A real pain in the A$$ to hear at those speeds.

 

never happened to me??

 

It is the rearview mirrors, at least on my 04.

 

it only does it sometimes its crazy
