Humming Noise

2xtreme1 · 05-23-2015, 06:35 PM

Hello everyone,
Its beeen a while since I have posted. I've been busy with life.
So today I was driving my Z, and I was driving rather aggressively. Oil temps went up etc.
Anyway, after about 5-6 mins of hard driving I started to notice a humming noise. This sound seemed to be coming when I had my foot engaged on the gas. I had no idea what it might be..
When I let go of the gas, the noise would stop.
Anyone got a clue?

Shout out to ANDREW! AKA DEPOINTFIVE(I think, cant remember username haha) it's been a while! I hope you're still on here.

pss: I want a Porsche now

What? haha.
Umm I only have 12k miles on the car. I am not that good with cars parts and pieces, but based on milage I don't think it is that. Or am I wrong? Again I have no clue. lol
I figured it was because the engine was running way hot. I want to say that a different time when I was driving it hard, it did the same thing. I am no track expert, but I wouldn't track this car stock without doing some work. And I know from past years that this has been the case. Nevertheless, I was driving it hard, but not like "Track" hard and I felt it could not keep up. Or is it just me?

oh... torque converter acts like a flywheel/clutch for your AT system. but honestly i have no clue on AT 370z's.. just a wild guess since u said it makes noise when you're on the throttle.

Thanks anyway! Hopefully others can chime in.

Are you sure it was not your passenger making the noise? My son sometimes makes that humming noise when I accelerate lol

Where is the hum coming from? Front? Mid? Rear?
Can you be more descriptive as to what the hum sounds like? Or post a recording?

Wild guess: you are hearing air going into the intakes.

haha. @ beemaz
SouthArk,
Hum seems to be coming from either around the engine side of things or right underneath me.
I don't think I can be too descriptive. I can't find the right words, but next time I will definitely post a recording if it happens again.
