Went out and drove the car hard for a while today and the power is very nice, but after doing some fast starts and accelerating hard for a short while, the car loses alot of power. It's not going into limp mode, just deactivating the supercharger clutch. (I'm sure that's the problem, since my supercharger clutch makes a bit of a sound when it engages)

So I pulled over, turned the engine off and then right back on again, and drove away. Power as normal now.

What is causing this? Water temp gauge reads right in the middle, perfectly normal.

This is a bit frustrating, any ideas what is causing this?

Thanks guys!

Intercooler pump is most likely dying. That's my bet.

Should I replace it with a stock pump or upgrade to a Johnson CM30 Intercooler Pump?
Or is there a better pump that you guys recommend?

Thanks!

I replaced mine with the new Bosch stock pump that flows more. The CM30's are hit and miss and are not plug and play. The Bosch is plug and play.

Can you give me the part # for the increased flow pump you used? Seems like an easy DIY install, yeah?

Thanks for the help man, I appreciate it!

was the problem fixed im having the same problem?

nidyanazo

Yes, with a new bosch pump, the one ending in 010

mbcl55amg1

I changed that yesterday and still nothing

radride

Did you install it correctly and not get air in the system?

What is the proper procedure to take out the air in the system in case I have some?

nidyanazo

IT's SELF BLEEDING.

The air automatically bleeds off into the overflow tank.

You have to bleed E55's, because they have a different setup, but not CL55's.

I'm uploading a video for you to watch I just made... I'll post it in a few minutes.

I appreciate that dude can't wait to watch it bc this is very frustrating

That's great man thnk you unfortunately I've done all of that.this is my third pump and still nothing. I also have a new clutch installed just a few weeks ago. It olny works in the morning wen I first turn the car on to go to work

mbcl55amg1

Do me a big favor can u check if u have play in the clutch cuz I do

nidyanazo

No play in the clutch but I do have a little "squeltching" sound when the SC clutch activates. I assume it's time for a new belt..

How hot is the car getting? Maybe time for a radiator flush and refill?
The ECU seems to sense if there's a heat problem and shuts down the fun. One of my next mods will for sure bee the big heat exchanger.

mbcl55amg1

I lost that sound wen I put the new clutch in kinda miss it lol I'm definitely gonna flush my radiator and see wat happens...and my car is at normal operating temperature a lil above 80

radride

Great video. I didn't realize the CL55 was different. I'm just used to the CL65 because that's what I have.
