Gold FFM cweeden 213 Posted October 11, 2007 Gold FFM Report Share Posted October 11, 2007 (edited) Is it related to engine RPM or to the road speed? If it is RPM related then you might want to check the belts for tension (also check the intermediate shaft for wear in the bearings while you are at it). If it is road speed related then I would agree with Mike above. I should add that tight belts can often whine. cheers -Chris Edited October 11, 2007 by cweeden Quote Link to post Share on other sites

LotusS4S 0 Posted October 11, 2007 Author Report Share Posted October 11, 2007 Does the whining go away when you let off the throttle? YES.. It goes away until I either rev the engine or speed up. If I'm driving at 40 and put it in neutral, then the whining decreases significantly, buy as soon as I engage a gear and the rev goes up the sound increases. I will check my belts... the car is still quite new and the belts seem fine by visual and touch. I'll have to take it in for an inspection. I'll try to take a sound bite but that might be difficult. It is not a super loud whine... It's a consistant whine (bit of a buzz to it).. It reminds me of an old aftermarket stereo amp I had in my Honda... When ever I had my headlights on and increased speed, it would buzz and whine.... That's as close as I can describe it.. Thanks guys for the info. So, Does the whining go away when you let off the throttle? If you're driving in a gear and the rpms are steady do you hear it? How about when you are in reverse? Can you post a sound bite? If it sounds like it's sucking air and the sucking/whining goes away when you let off the throttle, but you're still moving at a good rate of speed, I would inspect the hoses on your turbos. It could, pretty much, be anything. Without more information or a sound bite, I can only speculate. Quote Link to post Share on other sites

Is it a vendor other than Alpine? If so, it could be that your power wires for your stereo, amp, whatever is ran next to your speaker wires. This will cause that type of whining. Is your stereo on while you are driving? if so, turn it off and see if you still get the noise.

fmxa 79 Posted October 11, 2007 Report Share Posted October 11, 2007 I've always suspected the alternator, yet it's charging just fine and everything works. Quote Paddle Faster, I hear Banjos! Link to post Share on other sites
LotusS4S 0 Posted October 11, 2007 Author Report Share Posted October 11, 2007 The first thing I checked was the stereo (OEM), and then checked other electronics too... The alternator sounds suspicious but then again I'm not too sure. I drove in an '02 last year for several days and it did not have that same sound (quieter cabin). I've always suspected the alternator, yet it's charging just fine and everything works. Quote Link to post Share on other sites

LotusS4S 0 Posted October 12, 2007 Author Report Share Posted October 12, 2007 I know this might sound bad but.... I'm afraid an "expert" owner will walk into my car, listen to the noise and say, "dude... what you hear is normal" and then I go onto learn that this is the normal sound of the toothed timing belt that carries the whining sound.... I just know that my older 4cyl Esprits did not have this loud of a whine... I am in california and I will try some local folks. I can always just take it to get checked by a dealership. Thanks Where do you live? Perhaps someone close to you can come and help out. Quote Link to post Share on other sites

Former_rotorhead 0 Posted October 14, 2007 Report Share Posted October 14, 2007 I know you said it sounded electrical, but could it be as simple as the air intake? My belief is start simple and work towards the complicated. Sorry if I'm under thinking things. Quote Link to post Share on other sites
sandstrs 0 Posted November 4, 2007 Report Share Posted November 4, 2007 I would take it to a local dealer, if you have one, and get it checked out. Might as well get the "right" answer for a price than fiddling and ending up with more price... I think it is difficult for anyone to really know what you are describing unless they physically inspect the car and hear the sound "live". Speculation is a potentially expensive practice. When you do figure out what it is, please let us know. Best, Scott Quote Link to post Share on other sites

WayneB 2 Posted November 7, 2007 Report Share Posted November 7, 2007 (edited) I've always suspected the alternator, yet it's charging just fine and everything works. Definately could be a bad alternator bearing, serpantine belt tensioner bearing or the power stearing pump is just low on fluid. The alternators run very hot when the cars are just boost started and run to charge a dead battery (after they have sat a while on dealers lots), frying the grease in the alternator bearings (and cooking the electronics also).
