Need help, Hissing noise from engine at high rpms
 

Hey guys, yesterday i was getting on the freeway and i turned right semi aggressively and accelerated at the apex of the turn to 5500 rpms and hear this Hissing noise that grew louder as i accelerated....Now i hear it everytime i accelerate to 5500 rpms or when i turn right and accelerate alittle into the turn, I also hear it then.

The noise isnt a solid hissing noise like hiiiiiiiiiisssssssssssssssssssssssssssss..... Its more like hiss hiss hiss hiss hiss hiss hiss hiss hiss hiss, and as the rpms go up, the hissing gets more rapid.

Sorry, I dont know how to explain it any better.

This is probally the stupidest responce.do you think its the k&n air filter??

No, the stupidest resonse would be: Dude... the snakes in your trunk get pissed when you sling them around.

LOL nope not the filter, I think the issue is internal, If its only happening with RPM and not vechicle speed i think its inside the engine...UNLESS, When i was backing out my steep driveway, The passenger rear tire went out the driveway first, so it was hanging about 5-6 inches lower than the rest of the car, THEN i heard that hissing noise on the driverside of the engine.

As soon as the car or rear wheels leveled out, the noise went away.

yeah i guess your right.lol :)
