what seems an age ago, after being given another 100 horses the pump
( which had been replaced 11 months before ) so was probably the newer
Bosch pump, it couldn't handle the extra power. MB fitted the Johnson
the whole thing costing about 200 bucks plus the pump, 150 quid, and now
after nearly 3000 miles she drives perfect, never puts a foot wrong, and the
acceleration is

In fact I use it all the time, I still haven't got overextra power. Money wise this is the best conversion I ever had, K&N next
The Best of Mercedes & AMG
and doesn't go wrong just forget it , and enjoy it, It's almost silly to see
a limo flying about blowing everthing away, that's me,
The WP3 is an engine cooling pump, and will have the wrong characteristics for IC pumping. Their advertising only promotes the open-outlet gpm figure, which tells you very little about installed performance as an IC pump. There's no mention of maximum head or normal operating condition or minimum flow rate. Plus the current draw is only 3A - that's slightly less than the Bosch -002 pump (which will probably be more efficient in an IC installation).
I really wouldn't recommend using that.

Call me lazy, call me dumb, call me both. But the likelihood me emerging through the thread you linked with any concept of what IC pump to choose is damn low. Having compiled the data, in your opinion, what IS the best IC pump for the 65 series car?
This morning it was 69* and my car positively scared me. (love it)
Drive around on an average 92*-96* summer day, and the car feels about as inspiring as an SL500. Currently running the '010' iteration Bosch with the factory HE. Pump is functioning correctly and no air bubbles. She will run like a scalded dawg all day long anywhere up to about 80*-85* ambient temps. Creep up 8*-10* form there, and the fun is all over. There has GOT to be a way to address this.
P.S. - found a thread from a forum member who put a WP3 in his 600 (Ithink it was a 600) and he said it was the single best, most effective upgrade he had ever made. Curious.
I would just fit a new Bosch pump which I have done on my tweaked 65.
I had already bought a new Johnson pump and I had the Bosch pump
which had come off my 600. I done a simple test, connected both pumps
up to a battery and timed which pump emptied a bucket of water.
The old used Bosch took 15 seconds and the new Johnson took 18 seconds.
The Bosch was the newer upgraded version. I now have both for sale.
The Bosch won, so I suppose the rate of flow must be important as it was
designed to go with the V8 and V12 engines.
