I recently installed a jwt pop charger, I now hear a high pitched whistle under acceleration. Not the usual induction suckgin sound but a high pitched whistle. Checked for vacume leaks and found none. tightened all hose clamps and checked for leaks in the rubber sections.....


Any ideas??

its perfectly normal, mine actually got louder. the dirtier the more whistle!

 

i love these threads

 

yawn


























dont worry, its perfectly normal. Your engine is just thanking you for what you did to it!

 

as all the others have said, it's perfectly normal.
hell, i have a z-tube, MD spacer, and the stock airbox, and I get the whistle too.
my post = more reassurance.

don't worry about it the whistle.

 

this is the reason to buy a cai.

 

What, for the whistle? That is an expensive whistle!

 

you've got a leak. not good at all.

 

...no one expects a CAI to do what it actually does i guess... i love the sound

 

are you sure you didn't get this CAI?


Really though, it's normal.

 

mine only last for a seconds though at first acceleration. but yea i was told that was normal as well prior to purchasing it...so never thought much of it.

 

normal

 

I love that sound. In fact, I get on the throttle sometimes just to hear that sound.

 

Please uninstall your pop charger and ship it to me for free. This will solve your whistling problem...

 

As everyone has stated, the whistle is perfectly normal. At certain times it almost sounds like a slight turbo whistle when you accelerate lol.
