• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Educate me, please!

I guess you guys would know better than I would. I bought my car 10k miles ago and changed all the lines. I usually replace them all every so often. Either way haven't experienced any leaks that I know of, other than my massive exhaust leak.
 


If you can...try and get a video of the car going WOT (wide open throttle) and try and get the sound it makes...could be transmission related...could be an easy fix...who knows ;)
 
there is a few places they run too. look under the pulley of the supercharger and you will notice a line coming out, make sure it is on snug. then follow the lines around and make sure there connected well also. after that move on the boost bybass valve. the black thing over the supercharger that has a rod going into it on the bottom. im not sure for testing the procedures to see if it leaks tho.
 
Man, you guys all rock. Thank you for not making fun of me, and my utter lack of knowledge.


I can't wait to turn my car into a mean machine.
 
we all had to start somewhere. i wouldent know half the things that i know if it werent for this forum. its a great place to learn things. dont be affraid to ask questions
 


If the coupler wears to a certain point, it could either start slipping or actually just break apart, and then the supercharger won't make boost.

One way to find sneaky vacuum leaks is to get a can of carb cleaner.
While the car is idling, spray small amounts of carb cleaner near any suspect vacuum lines/connectors. You'll notice the change in the idle when the carb cleaner gets sucked into the intake.
I've heard of people using propane to do this too. You can use a blowtorch bottle (NOT LIT), and just use it to spray a little bit of propane near the vacuum connections.

Yea that is good info, I never thought about using somme propane but is nice to know because I usually have some lying around.

by the way, PrixT, don't be shy to show your appreciation for good info by hitting the Thanks button on the bottom right of the post.

I was talking to a friend of mine today, and we discussed the coupler. I knew it needed replaced a little while ago, and we are going to tackle that asap.

I'm pretty sure the coupler is toast, as I no longer hear it at all rocking and rolling...
 
Have you checked the tension pulleys? If you have one going bad, It could be letting the supercharger belt slip, causing a no or low boost situation. Maybe the tensioner is not holding tension on the belt causing it to slip. You could also have something wrong with the booost bypass. It could be just dumping the boost instead of building it. I guess it is possible it is the coupler, change it and see, you would only benefit from changing it even if it doesn't solve the problem. I am just throwing stuff out there.
 


All of the W-body vendors also sell these green couplers that are a bit thicker than the stock couplers but cost about the same.
They are also supposed to be more resistant to wear. Would be worth checking out if you haven't already.

98silvermist is right too. If the belt is slipping or the bypass is acting up, then they both could cause a loss of boost as well.
Both would be pretty easy to check if you're taking the snout off of the supercharger (well, it would be ridiculous to remove the belt without checking your tensioner when you're having issues - I would also check to see that all of the pulleys are properly aligned and not worn out).
The sound of tumbling rocks in the supercharger is usually the coupler though.

Good luck, and post an update on this thread if you figure out what the problem was. It's nice to have the results in case someone else is troubleshooting a similar problem in the future.

The tensioner is good, I just replaced it. Also, the belts are great too, new and where they are supposed to be.

This weekend, I am taking it apart, and going to see what is going on.:th_thumbsup-wink:

I've found that it take ALOT of propane to change the idle. I'd recommend starter fluid which also works well for drying flooded spark plugs
 
Idiot!

So, I really slowed down in my usual morning routine of getting kids off to school, and myself ready for work.


I listened to my car when I started it, and I'll be damned if I can't hear any rocks.


The rocks are gone! Fixed, right?



Just kidding, the coupler is gone. :th_wtf:



*goes and calls her parts man*
 


I have no idea about the coupler. I have a new one on order from a Pontiac guy here in the PDX area. My mechanic ordered it, and will bring it to my house when it gets here, and I will be installing it. I really shouldn't call him my mechanic, I should call him my mentor...



Whats a MAF?

Mass
Air
Flow

Sensor; it is located at the top of your throttle body and it could be going bad...but then again when MAF's go bad the car wants to die...and you say it drives fine that is whyI do not think it is MAF related. When you get the oil drained out of the supercharger, pull out the bolts of the snout (you'll have to remove the alternator), and replace the coupler...you should try and get a ZZP Coupler as mine went bad around 70K and I got one...cured my car right up. I never had boost issues but it did make a nasty sound...hope you it get it all figured out ;)
