If the intercooler pump isn't working properly and doesn't seem to be working most of the time, is it bad to drive the car? It's overall sluggish feeling and not as responsive probably from high IAT, but its very obvious sometimes when I'm on the freeway when the S/C is completely shut off and pushing down on the pedal doesn't have much response. I'm waiting for the new pump to arrive and I just wanted to make sure its not bad for the car or for the S/C if I keep driving it. I understand the shutoff is to prevent the S/C from burning up.

no, the supercharger shutoff is to save you from blowing up your engine....
it won't hurt anything to run it right now, just take it easy until you get the new pump...

Your S/C is shutting off because it is overheating...reaching max temp before protective shutoff. This can't be good for the longevity of the S/C. I would say, drive like a granny, and replace as soon as possible.

I'm assuming the IC pump not working properly could be potentially more harmful to the engine than to the S/C? =\

and you are correct, the potential hazard is to the engine, not the supercharger...

I think my IC pump is going out, is it possible for the pump to be intermittent. When I start the car and run for a minute and turn off I can hear the pump running after I turn the car off.
My symptom is highway driving and SC not engaging and the lawnmower affect. This is after sitting in heavy highway traffic.

Just got my new pump from Diversified products, Bosch part number 0 392 022 002. As for the cutting of the wires and connecting, does it matter which wire goes on which male post? I notice the posts are pretty small.
Thanks.
Thanks.

Thanks again guys this post saved me big $$$$. Damn near cover the cost of my H&R coilovers!!!
FYI the connector I used to connect the new pump was an old bosch connector from a spare wiring harness. I soldered it into the stock wiring harness. Factory looking and watertight. This will make future pump swaps easier.

Not an AMG :(
I'm getting ready to change mine (got it for $61 on e-bay . Did you disconnect the ground on your battery before you changed yours - or does it really matter?
Thanks to everyone for a great write up on the topic!

Thanks for sharing the Lightning pump install. Followed your instructions to the letter. Always pleasant to perform a task and enjoy instant results. I'll get to Irwindale and make some baseline runs, pronto. Let the mods begin...
P.S. Is there another AMG in your future?

i am selling the car for 3 reasons:
1. i need something bigger, so i am buying my dad's diesel suburban because i can pay cash for it and it still gets 20mpg...
2. i need to free up some money to fix my evo8, i blew-up the motor and ecu, it is going to be expensive...don't ask how i did it, i still am not sure how it happened, the shop is looking at it.
3. i am contemplating getting an E55 or something with the words Renntech and twin-turbo....

I paid a local mechanic $60 to install and I tipped him $15.
It took like 2 hours total..
very easy.
car runs normal now.. and I have not felt constant power of this car for a long time..
after a few runs, I was grinning more than my E55.
i'm thinking of keeping it..
there is a bit of hesitation still.. but I think its due to the "no resonator"...
i'm putting it back.

the c32 feels so much more nimble.. and light...
the E55 is so much smoother and powerful, but believe it or not.. coming from a pulley C32 and E55 is not a GIANT difference.. in terms of speed.
E55 is by far faster vs stock C32, but with a nice C32 Stage 2 set up, you will be not far away.
I needed the space for the my 2 little boys and the E is perfect.
I thinking of buying a used Acura or Honda to beat around, but I'm tempted to keep the C32 for 2 more years and pay it off.
I do also have an SUV for the wife and kids.. .so its tough choice.
