Few issues with my car
Background- 2003 E55, clocking 47,xxx KM (yeah, 47k KM), running EC tune+heat exchanger, outside temp 12-17 degrees c'.
1. After WOT let say 20-200 km/h for one time and than slowing down to about 100km/h and WOT again- supercharger won't engage and car will gain speed pretty slow.
2.from 200km/h it feels like car's gaining speed REALLY slow, can take few long sec' to go from 200 km/h to 230km/h, much slower than I can expect a stock 5.5 supercharged engine.
Any suggestion on what's wrong with my car?
I thought the upgraded HE should solve the supercharger cut off after few (sometime even one) strong pull but I was wrong.
In addition I really can't understand the fact that from 200km/h and above the car feels "chocked" and feels hard to gain speed.
I'm planning to service my car in few weeks (oil change etc') and already ordered new K&N air filters to replace the stock ones (if that can assist) but any special things I should check?
(Fuel pump is new from about 9 months ago).
Many thanks, Merry Christmas and HAPPY NEW YEAR!!

Hi
I have had the exact same issue happen to me, it has happened twice in the last 6 months.
I thought it was just the supercharger disengaging but happy to hear others thoughts on this.

Have a mechanic verify the pump in your supercharger cooling circuit, or heat exchanger circuit is activating. Doesn't matter how big your new exchanger is if there's nothing flowing through it. And even if it does activate, it still might be pumping well below capacity. The pumps are known to **** the bed. Might be time for a big Johnson.

Thanks for the replies guys.
A new s/c pump should also solve the car's "laziness" over 200km/h?
In other words, the weak acceleration over 200 might also be related to the s/c pump?
Can you please give me a link where I can buy upgraded pump to replace the stock one? Is it plug & play or need some mod' to make it work? (Better if plug & play).
Last thing, would appreciate if can recommend which spark plugs to use & if possible a link so I can purchase. (To make sure, how many needed?)
Again- many thanks!!!

Theres a link to the Bosch 010 pump, although you might want to order from a local source so the shipping doesnt kill you!
And yes, they are plug and play, Just remove the bottom panel, clamp off your coolant lines, unplug and remove the old pump, and replug and install the new one. There is a DIY in the DIY thread that is stickied at the top of this forum.

I had the same issue with my car.
New Plugs
Used Coil packs from a low mileage car (don't forget mbz was using the same coil pack technology since the early '90s)
Wires
K & N Filters
New bosh pump
car pulls HARD and strong 60-130 like nothing. scares me how fast the mph gauge moves.

Hi
My coolant pump is just over 8 months old as it is a new larger one that sits in the trunk mounted coolant tank I installed with an upgraded front heat exchanger and split coolant system.
I can confirm this pump works when the engine is at idle but can not view it in operation at high speed as I am in the driver's seat, but my guess is it does work or else the supercharger would probably disengage after it's first hard run where my issue has only happened twice in the last 6 months.
I have some colder range NGK plugs that should be installed early January and hope this fixes the issue.
If not I will look at the coils and wires.
If by chance that it is my intercooler pump in the trunk mounted coolant tank not operating correctly, wouldn't it show up as high combustion temps on a Dashdaq obdii monitoring system?

OZZYAMG

definitely the H/E pump - I'd suggest the new Bosch 010 pump, it's plug n play and works great!

Just to make sure, the link is correct? (It doesn't show the 010 pump but the 386, or am I wrong and the link is for the correct pump?)
I noticed some using the OEM 010 Bosch and some the CM30 by Johnson, what's the difference between the two if I may ask?
The Johnson is also a plug & play?
And again- thank you so much guys.

I believe the Johnson needs to be wired in - the Bosch is direct fit

pretty much if you're running a stock H/E or larger H/E the Bosch should do you well, if you run a higher flowing pump you may actually be pumping the coolant too fast to allow for cooling - the higher flow pumps are great for trunk tank setups and large volume setups > 2L (the largest H/E in the stock location are ~1.8L in size)

Umm increasing the volume of fluid does not increase the flow of said fluid so regardless of tank or heat exchanger core capacity the flow will still be restricted by the same factors as the smaller setups. Increasing the actual flow would require reducing inner circuit restrictions such as bigger or more efficient fittings, bigger lines and more efficient flowing cores/end tanks and last but not least, the pump. That being said I've yet to see a compelling argument with any credence that suggests a higher flowing pump would some how reduce the cooling capacity in the circuit in anyway. Now I'm not advocating everyone run out buy whatever, but from my modest understanding of it all the more water you have the better and the more flow you have the better but that's just me. Either way it's a bit of splitting hairs because I think it will be the capacity of the circuit and the efficiency that have the most influence on how long your car will last before heat soaking.

And if you pump 20GPM's through your inter cooler it will have absorbed less heat by volume than had you only pumped 10GPM's. The circuit has 2 sides that are equally effected by this volume stuff. One part designed to capture heat, the other designed to release it. It may be basic but not at all the picture you just described.

As always there are limits on everything, but increasing fluid velocities tends to make heat exchangers more effective.

i want to take it one step forward and check IAT temp' etc'.
can anyone recommend me an OBD2 scanner who work properly with our car and can show info on my android phone ? (im using Samsung Galaxy S4).
what app is better for my phone?
cheers!

im updating so it can help others in the future-
i changed the SC pump, installed the Bosch 010 and i found all my lost horses!!!!
damn, i didnt expected that big difference just from getting a new 100$ worth pump......better than a tune! Lol.
the car now feels much more aggressive than before, lets just say that i own the car for 11 months now and it was the first time my wife actually felt worried about the speed-while i was actually driving as usually, just car respond much much better and became really much faster when going over 170-180 km/h (especially when before it used to "chock" after 1 hard pull).
bottom line- if your a new owner of a car using that engine, before going for mods- get rid of the stock SC pump and go install the Bosch 010 or the other "known" pumps.
those stock pumps acts like a speed limiter....
