hello all i am still having a problem with my S/C. it flutters when boosting and i think it is my bypass valve leaking durring boost. i can make up to 8psi of boost on my guage but around 5psi it starts to flutter/leak and i loose all over and engine gets cought up on it self like the air/fuel is all messed up which if it is loosing boost it would be.
SO my MAIN QUESTION other than what do you think is wrong / DOES ANYONE HAVE THE MANUAL FOR THE GM 12498660 S/C. im looking for the part list pages so i can get the bypass valve part number so i can replace it. i lost my book during a move and cant find the PDF file on line. So a PDF, copy and fax, or just the part number would be helpful. Thanks a lot everyone

thanks very much but that manual is for the Ecotec engine. im looking for the 2.4L m45 S/C kit book 2000 Z24
Should have said it was for the M45/LD9, but i did think the P/N looked different....
Boost > N/A

Paying someone to install parts and bragging about it being fast, is like watching someone bang your wife and being proud to raise their kids.

Eat my shift
thanks again but i believe that part number "88960487" is from the old discontinoued m45 blower kit "12498287 " im looking for the new part for the "12498660" supercharger kit. i had the part number a few years ago and i could order it from GM parts direct but i never did and since lost that part number so im still on the lookout. so back to making a few calls
