I hear a very distinct mettalic "rattle" when I bottom out the boost gauge and only then but it is faint as I have to turn off the stereo to hear it but I hear it..

Figures now that summer is here...

What do you mean "bottom out the gage"? If you mean you hear a faint rattle at WOT, that could be audible knock. You don't want that, knock damages the engine.

Do you have a smaller pulley on it, if so what are the supporting mods? If it is at idle then it is your supercharger coupler (an fairly easy $30 fix).

when we worked on his car in my garage we noticed that the coupler was shot.. but we didnt have time to work on it then...

get your coupler on there first and then see how it sounds

I mean that when I hit the top end of the pedal and the boost gauge needle hits the top end but when I back off to just the top side of the "redline" on the boost gauge it sounds fine.

I remember that now haro and will find some help with it and hope thats it.

A.F.A.I..K. my ride is bone stock,no mods.

In did try to change my SC oil a month ago when I had the SC belt tensioner installed and could only pull out one bottle and put a bottle back in and it is up to the threads....anyone explain that one as I was always told they hold 2 bottles ???


Hows that top end coming haro and as you can see in my sig the pics of my car and them disgusting exhaust pipes sticking out...... :P

the M62'* hold less SC oil than the M90'* that most people talk about

Since you have a spare bottle of oil already, get yourself some red gasket maker and a coupler, and an outlet gasket and two yellow o-rings. Total investment should be about $50. Total time should be about 2-3 hours for a rookie if you follow our instructions.

Thanks will do that once I sell my laptop...

While on the subject is there a proper place to sell a laptop here or no ?

Personally..I'd get the SC gasket from the parts store as Felpro for $6 it comes with the yellow o rings.

Couplers don't rattle at full boost. They rattle at idle.
