okay.so.as I shift into 5th gear.and hit around 60-70 mph.I hear this whistling noise coming from the front of my car.like it's coming from my engine or something..anyone know what the whistling sound is??.
thanks

p.s. i drive a '94 del sol..

 

possibly wind? intake setup? supercharger?lol...is that the only time you hear it?

 

supercharger.i wish. .but ya it's the only time i hear it.when i'm at that speed.i always thought it had something to do with my intake.but the setup is fine.

 

it could possibly be your throttle body

 

same here, i have a sohc and a aem short ram intake. it whistles at acceleration. kind of cool.

 

could it just be wind??
Ive heard of certain intake manifolds/t.b's making a whistle but that was every time you rev it or accelerate,not just at one certain speed..
what engine/intake setup do you have??

 

i have a d16 sohc.with aem cooler intake..ummm..it could be the wind.but i'll check the throttle body to see whats up..

 

there's probably nothing wrong with it. Sometimes hondas whistle. It's how they roll. My D16Z6 did it, my B16A did it. My friends B18C5 did it, my other friend's D16Y8 does it. My F20C does it. My B18C1 did it. My current B16A does it. I could go on.....

 

Yeah, my old ls-v did it at certain throttle. Same with my em1 now, you'll get used to hearing it...

mine whistles at idle ...seriously

 

it could be a belt that is very slightly loose and makes a little whistle at certain rpms. it could either be power steering or ac belt.

 

I bat that it is the throttle plate angle causing your whistle. Hell, my CRV does it.

 

The EW in my 86 whines at 5 grand like it was a supercharger

Honda's just make noise.

 

mine did that also it was a loose coupling..

 

my car used to whistle bad...then i took the bike rack off. problem solved. cars do that when there is a small gap somewhere that may only open up at 60-70 mph. thus creating this confusing problem. check clips in the front. bumper, hood, that rubber thing under the hood. its not going to go away completely though.

 

Yeah mine is a B20 as well

 

That's the "sweet spot". My EM1 whistles when I hit that spot in the throttle. I can keep it going while accelerating too.
It's normal.

 

The whistle is probably from a ripped weather seal. Happens to most del sols and can cause that whistle effect driving in higher speeds. Check all the seals on the targa top!

 

could it be sensors?????

 

damn, i saw the subject title an thought i was gonna come in here an see a new rap video or something...

lol i've heard that whine. It's totally different. The sound I was referring to is like an actual whistle. But I do know the whine you're speaking of. My friend had a 85? Crx. Winter drift monster....with a hole in the floor from sliding into a tree stump.

 

I've seen aftermarket intakes whistle on cars before.

 

i have that same problem...except its usually when i hit vtec @ 5500rpm....i know i have a small leak in the header since im missing a nut on one of the bolts where the header mounts....but i dont know.

do you have an exhaust leak too?

 

i cant belive out of everyone on this web site no one knows exactly why. mine all do the same thing. i saw this post topic and was like cool im finally gonna figure out why. and turns out still know one knows.

Because there are different reasons it could be making the sound. Lots of ideas have been proposed, but how in the hell are we supposed to diagnose every car that's ever had this generic sound from somewhere on the front end (or anywhere)?

Here's the closest you're going to get to a solution to all of the whistling.

It's caused by air.

It's either leaking in or leaking out, thereby causing a whistle. Honestly, it doesn't even have to be leaking at all, as long as it's passing over the right kind of surfaces (like the guy with the roof rack that whistled).

Where's it's leaking in or out of depends on the vehicle. As you can understand, there are an awful lot of places for this to occur on a vehicle.
