engine hum/buzz?
 

hum and buzz when I floor it...not the redline buzz, almost like a highpitched hum only when I floor it and take it past 3500 rpms...too lazy to do a search...checked coolant, its okay...

is the coolant light going off, or is it just a random buzzing noise. It could just be screwed up electrical stuff

uh
 

coolant light is not on...

...and the sound is most obvious from the outside...I didn't notice it until my friends told me about me it while I was drifting...its only when I floor it, and go above 3500 rpms...:D ...

...they were like "does that buzzing sound get annoying?", and I was like "what buzzing sound?"...dammit, now I can notice it...
