[SOLVED] What is this whistle noise under acceleration? (03 Tacoma, 3.4, SC) (1 Viewer)

[theferg]

My Tacoma has developed a bit of a whistle... Any thoughts on where this might be coming from? Something to do with the supercharger perhaps?-- but thoughts on what/where/how? I've had the supercharger on for about 4K miles or so now and it just started this whistle the past week. Only happens under ~mid acceleration and only while driving.

2003 3.4, TRD supercharger (black 2nd gen version), 99k miles on motor/truck, ~12k miles on SC now, auto transmission.

I think I found the problem....

Yep, that was it. Replaced it with some spare vacuum hose I had around and the whistle is all gone. Yay!
