gents.

This morning I noticed that Maggie had a bit more of an "electronic whine" if you will, and when I popped the hood - well - if I had to guess, a bearing is going south.

Anyone experience a similar noise and NOT have it be a bad thing?

Make sure you have coolant in the intercooler container. I had a leak, lost coolant and the pump noise was quite noticeable. Also some of the early model maggies for the CTS-V had a steel drive shaft that would rub against the shaft cover. Usually only at certain rpms.

I've heard of the shaft rub too(sounds dirty when you say it like that).Since then, all their kits have carbon fiber shafts.

Had a bearing go bad on the Silverado SS version here in Minnesota. Get a hold of Magnuson; they'll get it fixed up.

Make sure that you are not making contact with the cross bar. My blower makes contact when Im on it and it transmits the noise.. Also, the metal jack shaft rubs the blower case on the passenger side. (non carbon).

I've verified that nothing comes in contact anywhere. It isn't the intercooler, as it is engine running only. I pulled the serpentine belt off and spun her by hand - all seems normal (low RPM, I know). Though I don't have the carbon fiber shaft, I don't have the cover either (very early adopter - been there - done that).

Guess it's on the phone to Magnuson tomorrow...I'll keep everyone posted. The V does sound interesting with two different whines, though :)

Well, If you really want to pinpoint the noise, get a mechanics stethescope. I use it when Im trying to isolate noises, squeaks etc. Im sure Magna knows where its coming from anyway.

lasstss -

I'm sure you're right. I did the old long steel rod trick tonight (pseudo stethescope). Seems to be coming from the back of the Maggie - and to be honest - sounds like gears :eek:

Belts are all looking good.

Thanks for the input, guys. I know Mag will take care of me - they always have.

Besides, this gives me a good opportunity to replace heads and cam (wait, did I just say that?) :lies:

Yep, It was Blitzer.

FWIW - I have exchanged the unit before in 90 minutes. No need to pull the wiper assembly.

Actually, I'm quite good at this - I've had the S/C off no less than 4 times now :cookoo:

Calling Magnuson now.

:yeah:

Seriously, I better start getting hands on with the V. I've been taking the V into the dealer where they have been installing everything for me because, I don't want to ruin any install. Better yet, I don't want know what I might have ruined doing the install.

When I worked on my other car, I enjoyed the gratification of knowing I installed this and that. When someone had a question, I knew how it needed to be done. The only drawback on that was I sometimes knew little things I didn't exactly finish correctly. In the back of my mind I knew I had to go back to that part or mod and finish the install correctly. At the end that took away from the value I had for the car. Hence, I ended up selling my old project.

Anyhow, WW keep us posted on your results. ;)

Further testing shows it is in fact the back of the s/c. Seems to be the bearing on the jackshaft, or possibly, the bearing on the input shaft/gearbox of the maggie itself.

Trust me, guys, Magnuson will take care of this. Glad I hadn't gone to the 2.6 pulley yet :eek:

Frank - get your hands clean and then dirty them on your V. Pretty fun car to work on, really. In some ways, and SBC is an SBC :rolleyes:

This is just from memory of a quick conversation from months ago, so take this for what it's worth...

If memory serves, a mechanic informed me that the carbon fiber shaft was being used on current magies as it aided in reducing potential noise/bearing problems or something...

I have no idea if that is related to your problem, of course, but it is some food for thought in my mind. :)
