If this is what losing 115 hp feels like, I would NEVER recommend buying a run of the mill Crossfire. I do believe it is a loss of much more than that to be honest because now your intake system is struggling to get the air through the supercharger system, where as the NA Crossfire is designed in a different manner. With that being said, I plan on changing the pump.
To RL, the link you listed...that pump is Plug n Play? I just want to confirm this because I am about to order it. The dealer quoted me 479?!?!? for just the pump...hmmm, I do not have time to perform the repair myself so it has to go to the dealer. But if I can generate the part myself, Id much rather do that than pay what they are telling me. It makes sense to me with Maybach being a Benz product, but I dont like ordering car parts over the internet so I need to confirm this first.
Not trying to hijack this thread, but it only makes sense. It sounds like the same exact issue.
JJ - I like your concern about not hi-jacking this thread, but since the OP has acknowledged that he, too, might be interested in the I/C pump, I'll post my answer in his thread. If you have any further questions, just IM me and I'll be happy to help or point you to other threads where I've commented about my findings on these pumps.
The Bosch pump in the link I provided is indeed a plug-n-play since it is listed as a Bosch part number 0392022010 - the key is the "010" at the end of the part number - that indicates the latest Bosch revision of the part. I mistakenly posted the wrong link of where I purchased the pump from, as I actually purchased my pump from Amazon here:
but it's up to you where you buy your part from, just be sure it is the correct leading part number and ends in an "010".
If you need more help or have more question, just shoot me an IM - happy to help
