What is this noise coming from the engine? Just done a recenty swap and it was a huge hp increase, a little over double the hp, and when the car is in motion (moving ) there's this HISSING sound ( Psssssssssssh ) and ask you press the gas more, the HISSING sound gets louder. When you come to a complete stop, the sound decreases and then it's gone. This i all coming from the engine. I just put a new AEM short air intake. My car is a 90 crx hf. Is this normal? It's all motor, no turbo. sounds like turbo though. anyone knows?

 

get a video or atleast a recording.

 

It's the intake sucking air.

 

^indeed. mine does it too. Its like a whistle sound.

I kinda thought it was the aem intake also. I had a hf stock and it had less then 62 hp and it wasn't able to suck that much air in cause of the lack of horsie, but since this swap, i'm getting at least double the hp and maybe that's why the sucking of the air into the intake is what that hissing is!

 

What motor is it?

Yeah it's crazy like that...Those HF's are ****** beasts.... 8 valve heads turn me on.

 

Yumm......Hf's make the world go around....

i kinda feel like i'm being joked at!? it's not funnie!

 

hey theres these belts called "gator back" goodyear belts you can get at action auto parts and they give my car a nice whislting sound, almost like a mini-supercharger or something lol. but I suppose those grooves on the belts are actually for cooling purposes.

 

the grooves on those belts are for grip and you can get the gator back at almost any parts store like napa or kragens

 

My HF stock still made the same sound as it does not with the B16. Well, the B16 is a little louder I guess.

 

my b16 whinds alot. i'm not sure if it's normal. just got the motor. i was told it's the tranny. those b16 trannies are monsters. that with a six puc disc, i tear up axles left and right.

 

big exhaust leaks sound like that too.

my intake does the same thing sounds kinda cool though but after a while it gets annoying.....

 

Check the tube that runs into the side of the intake tubing and the other end is at the valve cover. If it is out it will whistle just like you describe. Look for a loose metal to rubber fitting near the throttle body. Bet thats it!
