Bizarre Noise under 5 psi+
 

I am not sure what is causing this noise? Is it pinging? or my fuel injectors???

But basically when running larger amounts of boost (over 5 psi) I can hear a noise similar to what a hose makes when you bend it like a V near the tip.
Anyone else experience this?

Tune it b4 u blow it up, good chance it's detonating

Also sounds like your just hearing the air charge flow through your intake pipes. Normal. Both of my setups have sounded like that.

And they sound like they're rattling?
I was thinking it might also be engine mounts.

are any of your charge pipes resting on bare metal pieces of the body? sometimes that can cause some noise at high boost levels. just a guess...

I'm not sure i"ll have to give it a look over again tommorow. Thats a really good guess, would make the most sense!

I love to hear the air going through my pipes. Sounds nice..

But ya, on my buddy's blown EF, he's has to pad his intake because it vibrates like all hell.
