very weird noise @ High RPM's
as of yesterday my car started making a very weird noise at high RPM's.
Theres no loss of power, stutter, hesitation or anything like that but the noise is pretty loud almost as if the were a vacuum kind of sound or something is hitting a fan. idk but this is weird and i cant even begin to look where this could come from iv'e checked for loose line n all that and everything seems to be good. Has anyone ever experienced anything like this?

A vacuum kind of sound, and something hitting a fan sounds like two totally different sounds lol. Do you mean a vacuum cleaner?
Without knowing which car you have, it's hard to start the diagnosis. |

Witha very vague guess I would say its either an up pipe leak or something with your airbox/intake/new filter? Could also be a turbo to downpipe leak. Give us a more explained noise!haha

well i have a 2004 wrx, i just changed the air intake..the problem still there..it sounds like something is hitting a fan and it only happens if you run the car hard at high rpm's.. today i also notice while swapping out the cai that my radiator is leaking fluid. could it be something with the radiator fans?

alright so im completely lost!!!!
in the last couple of days my car has been making many different sounds and also a difference in performance..theres a vacuum sound on low rpm's under 3k.. once past 3k it start making a weird hitting fan kinda noise. its coming from near the turbo. and as of today, i checked it out and its making a weird fan sound through all rpms. even when in neutral if i give it gas the turbo makes the fan noise while spooling up and its very loud.. while im driving the psi levels drop extremely fast at around 5-10 psi.. keep in mind that at the beginning of all this there was no power loss, or anything weird and now theres a huge difference in performance.. i dont even know where to begin n id really hate to take it to the shop n spend an arm and a leg |
