Do I need the IC Pump upgrade or no?
I know Im posting this in the W211 forum, but theres more action here instead of the W220 one. I have an S55 AMG and been seeing all this talk about replacing the pumps with Johnson CM90 and wiring it up to stay on all the time or let the ECU control it as is.
However I was reading that the S class has two heat exchangers, so do I really need this or is the problem of the SC'er shutting down really only primarly on the CLS and E55s?
Im looking to install an ASP pulley in the next week and if I really need this pump or something else, I was going to hit it at the same time.
Thanks

Vadim, thanks for the info, Should I upgrade the pump if the current one is still working? I take it easiest way to test this is to just hotwire the pump to make sure it even works.
If I get the CM90 is it a direct fit (besides the larger inlet/outlets), in that does it bolt to the bracket and stuff or do I have to custom fab one? Should I just put the CM90 on there or should I go for the Evosport upgrade, Im just wondering how much better that Evosport one will be if I technically already have 2 heat exchangers. If there is no point spending the big cash for the Evosport when technically all I need is a better flowing pump, might as well just do the pump right?

Call me lazy, but I see no need to do the upgrade unless 1) you want to turn consistent times @ the track often or 2) your current pump is failing and you are out of warranty.
Otherwise, I find that the car runs and dyno's GREAT before the head-soak. And even then, we are talking a minor performance hit, at least in the mild climate here in the SF Bay Area. Not sure about Texas or Florida type weather, maybe there's more need for the upgrade in hot climates.
My car feels more than fast enough with the Renntech pulley/ecu upgrades and (ahem) the sprintbooster. If you are itching for more speed, and your current setup is working fine as is, spend the $ on a pulley/computer upgrade. If the stock system is failing, you will know. MAJOR loss of power. Awful feeling.
Just my opinion,
Skeeter

Oh, one more thing...
What do the S55's run the quarter in? Are the close to the E55? I'd imagine the larger car makes for a slower car, but maybe the weight transfer is better with the softer suspension? Never been in an S55...

Thanks for the info Chiromikey. I may look at the CM30. But as Skeeter said, if my pump aint failing now and works, I may leave it as is and just run with it till it falls apart.
Not sure what they run in the 1/4. They are about .1 slow in the 0-60 according to Mercedes, but who knows if that is even true.
