No Boost?

After a hard run the supercharger takes a break. Almost like it has to cool down. Anyone ever have this problem? How can I fix it? I want boost all the time

Yes, many threads on this as well as DIY thread. I replaced mine with a CM30 pump, did consistent pulls back to back with no issues

Just shoot EUROCHARGED a PM, tell them you need a cm30 ic pump, they'll get you squared away. $150 I think it was, not bad.

Yes, that is the exact problem I had and many of the members on the forum as well. The DIY is part of the sticky thread marked DIY in this subforum.
