I have this whine and I can't tell if it's from the SC or not. I don't recall picking it up with this whine and I just started noticing it. I just changed the idler, tensioner, and belt and the noise didn't change. Am I just being OCD or does the whine in the video sound like the blower or some other bearing is going bad?

It is a whine that sounds like it is coming from the right side of the motor. It changes with RPMs, but is most noticeable between 1 -3k. The supercharger whine still sounds strong. I am not sure about any power loss. I haven't had the car long enough to know (still don't have registration) if it is low on power and don't have a boost gauge.

I plan on changing the SC fluid this weekend, but if this noise is a clue that it's going bad, I would rather put a replacement on. Any insight would be helpful!

Videos now uploaded! Give them a list and let me know what you think.

 

Any overheating problems? Could also be your water pump.

 

No overheating problems currently. I am going to replace the waterpump when I do the supercharger service, so I will be addressing that as a potential issue.

 

Belt slip ????

 

I was thinking that as well, but I just replaced the tensioner, belt, and idler pulley without a change in the noise.

To me, on my cheap Windows Media Player and laptop speakers it does sound like the whine of the blower but wouldn't rule out alternator or maybe water pump. If you are concerned and want to be sure, maybe start probing around with a stethoscope while a buddy gooses the throttle (be careful not to stick the probe in something rotating).

 

I appreciate the feedback. When you said the whine of the blower, do you mean that as the "normal" whine it has at idle or that it is the blower going bad? I've attached another video of it from early tonight. I used a stone to bring the RPMs up a bit, so this was not at idle, at an attempt to make the noise more noticeable. I used a long screwdriver as a stethoscope and poked around a bit. You can definitely tell there are moving parts in the blower, but its not like I could hear the exact noise.

The car has 193k on it, but I have no idea what the blower has on it. I plan to do the supercharger fluid service, but I'm second guessing whether I should even both or just pick up a new unit. I already plan to bolt up a new water pump, gaskets, and the fluid change.

 

It probably is the original unit, with 193K on it, same as the motor. And agree - would go ahead and do the supercharger service (use the Mod MINI YT vid as a good go-by), and the water pump swap "while you're in there" (thermostat too). See what comes out when you drain the blower, can also bore scope it and see how it looks inside. Would think as long as chunks, flakes, metallic particles, bolts, old Matchbox cars etc aren't rattling around inside or come out with the old oil, you're probably okay.

 

Alright! So I think the waterpump was the culprit. Please listen to the first video. It sounded like a creeky old gear. I confirmed this when I unbolted the waterpump from the supercharger.

HOWEVER! Take a listen to the second video clip and let me know what you think of the sound. I've never heard one before, so I don't how quiet it is supposed to sound. I hear a little something, but it sounds pretty normal to me.

Would love someone to compare it to what they heard when they changed theirs.

Thank you!!

 

hi did you ger rid of this whine? I have the exact same issue. How did you fix it?

thank you
