    So I've noticed tht when I take off from a red light or stop sign tht my truck makes a noise kinda like the sound of a turbo in some cars makes. It kinda sounds like a siren and I would look behind me for cops and would realize tht it's coming from under the hood. Does anyone know what this noise could be. I'm sure it's nothing bad

    You sure you don't have a turbocharger? Or a supercharger?

    Maybe you've got a neighbor's cat stuck in there?

    Toyota has been known to lube the drivebelt of certain models with rare endangered Amazonian Speckled Turtle dung. It does emit weird sounds now and then, but doesn't usually sound like a siren or turbine. Maybe they're using the cheaper Peruvian Spotted Turtle dung now :notsure:

    If you no have supercharger then you may look around for a cracked or collapsed vacuum line. Had o collapsed vac line on an old buick one time that made the siren like noise.....woooooh wooooh woooo!! :D

    If it doesn't have TRD on it then it's not a supercharger. IIRC there's no cover.
