2016 Tacoma hipgh pitch whistle when accelerating fast

When I floor on the gas I hear a high pitch whistle from the engine. Sounds like a turbo kinda whistle(now obviously there is no turbo in the engine)

I think it's normal just wondering if any of y'all have heard it too?

 

Never heard it but I'm done for the day...Maybe I need a week off of Tacoma world.

I can't have another issue with this truck. If I hear a whistle tomorrow I'm going to stab you in the toe.

 

Alrighty then.... let me know if you hear it tomorrow!

 

Maybe the Lower A Arms are the source of the Whistle.

 

I hear it all the time but I do have a CAI though.

 

It's the intake on the V6's.

 

So normal right

 

One time I glued a metal referees whistle to a coworkers tailpipe.
Took him 3 days to figure it out.
Check your truck.

 

Yeah, I really hear mine when accelerating from a stop with window up or down. It's that sucking whooshing sound.

 

Yeah, I love that third gear whistle. I roll my window down. Pretty sure it's the intake.

 

its the supercharger wine......lol

 

Yes have had this since day one. Not sure it's intake related though (for me)

 

Bluetooth obd2 reader and monitoring app like torque pro will show you vacuum at idle which would help rule out a vacuum leak

 

I've noticed it a couple of times under >50%<75% throttle application around 2nd gear in my 2015. I just noticed it tonight merging onto the freeway.

 

Totally normal under full throttle. It's the intake system I'm pretty sure. I heard it a bit when stock but after dropping in a K&N filter it has just become more noticeable than before. The Tundra did the same thing with a higher flow filter but it is caused by some mesh in the throttle body. Haven't gone that far in the Tacoma though but it's probably something similar.

Nothing to worry about.

 

Whistle for me seems to be fuel dependent. Mine will not do it with ethanol free. Whistles like a champ when using cheaper gas. Don't know why, but it seems pretty consistent as I've tried to notice changes with different tanks of gas.

 

It's the high pressure fuel pump. And it's normal. It will be most noticeable when you let off the pedal after a hard acceleration up to about 45-55 mph.

 

You probably have this installed
