Oh - a couple of links:

1. turn up the boost
2. advance the timing
otherwise you end up actually losing power most of the time...

Hmm... I would also be interested in such tests, but what I was getting at with my prior post is the problem of heat soak that they are trying to address in part by intercooler modifications. The real benefit might not be increased horsepower, but more consistency/less fluctuation in power from heat effects on the SC.

Search for 10-24190-1. This is a very high flow pump. I can't find the thread anymore but it flows several times more than the stock pump.

Here is a thread in the E55 forum that is worth a read. It even talks about flow of the Johnson pump. https://mbworld.org/forums/w211-amg/144890-ic-pump-does-really-make-difference.html

I just noticed today that my pump does not make any noise when I shut the car off. On the flipside, I havent really noticed a lack of power. My car is still under warranty, what can I tell the dealer to try and get them to replace it? Will the pump always be run after the car is shut off, or is it intermittent

It is a really easy install (just have to swap the tube housing from the old pump onto the new one and cut the old electrical plug off, replacing it with two female spade connectors) This pump seems to produce plenty of flow. . . I have run it hard for the past week, and it is flawless.

I have run it now for 300 miles, and my washer reservoir is still full
I think that either the pump was leaking as it was failing, or that it was only pumping a trickle, which caused the water to superheat in the intercooler and then evaporate into steam in the (unsealed) washer reservoir, causing the level to constantly be dropping.

Most of the above is supposition. I may be completely wrong, but I would definitely take it in and have it checked.

looks like I'll take it in and have them look at it and do that service campaign too. Im sure the dealer will tell me "could not replicate problem" or something to that matter. My warranty is good til 07, so I got some time I guess

If you are stock, then the intercooler pump uses your coolant reservoir (that lunchbox-sized white plastic canister with green liquid (don't drink it! ) on the passenger side of the engine compartment). If you have Evosport mods, they route the intercooler pump to the windshield washer fluid reservoir.

In regards to the aquamist:
I have read that one BMW 318 owner with the downing atlanta SC had the plastic? portion of the supercharger rotor eaten away from the alcohol spray. I think the solution reacted to the material used for the rotor and ended up causing a loss of boost and power. He was spraying before compression.
edit: looks like he was using denatured alcohol and that ate away at the epoxy coating on the rotors
