I would list this in the SL section, but it seems that all the mod and help information for the M113K motors are found here...

My plan is to do a few mods with following parts purchased already for my 2007 SL55:

Weistec Heat Exchanger
Johnson CM30 IC pump
Weistec Plugs
Weistec Air filters
77mm clutched supercharger pulley
Scatter shield from latemodel 21
Belt wrap kit and pulleys from Shardul
Eurocharged TCU and ECU

After a baseline dyno, I started tearing apart my car to start the new part install. I do have a few questions for anyone that can answer (sorry, but there is much for me to learn about the AMG55.

Does blocking the oil cooler with the new heat exchanger have much affect on the oil cooler function?

I hear that the old Bosch IC pumps were not very good. Does this include my stock 2007 IC pump or is my original an ungraded pump by this time? it appears to work fine.

I didn't get any instructions from Weistec on the HE install and can't seem to find any instructions on their site. Do I need to remove the original HE unit? What is the plumbing that needs to occur with a front mount HE? Any guidance here would be helpful.

I hear that the factory MB plugs are indexed. Is this true with the Weistec plugs?

Thanks in advance...

if your pumps part number ends with 010, it is the upgraded pump. But even if it is the older pump (ending with 002) it still outflows the johnson pump.

the factory oil cooler being obstructed by the new HE is less than ideal. It will interfere with efficiency of both systems. If you can, shift the oil cooler so that it is beneath ... you can modify the venting in the undercover to support this (I did this on my 2003 sl55 when I added the PLM HE). Normally, you would leave your original HE in the circuit add the new HE in series (and after relative to water flow).

I have added a flow comparison chart that has been compiled using manufacturer supplied flow characteristics. If you want an upgrade, the pierburg cwa50 is a good choice as it flows the most (of any pump that the stock wiring is rated to support).

Cheers,

Interesting info Chris. My pump is working fine and I guess I assumed from reading all the posts that the new pump would be a big improvement. My bad.

I just found the part number and it is a Bosch 010. Sheesh... It's staying.

Do you have a picture of your shifting of your oil cooler?

Can you detail the routing of the hoses to the new HE?

Thanks for your reply.

I have more pictures (showing the modified undercover), but I will have to look around for them.

here are a couple of pics that may help in this post

I have attached a drawing of the stock charge cooler circuit. You want to install the new HE between the output of the OE HE and the pump. looking at the diagram, replace the short blue hose going from the HE to the pump with a hose going from the output (bottom) of the OE HE to the input (top) of the new HE. Then add a hose from the bottom of the new HE to the pump. I ALWAYS add a bleed line from the highest point of the new HE when I add one to any of my cars.

Chris - That helps me a lot. Thank you.
My biggest problem now is that I have a K-40 radar detector device that is mounted to the bottom of the bumper support. I can relocate this device, but it still needs to have a clear shot in front of it. If I move it all the way to one side, it will work. God knows how many times this thing has saved me from a ticket. Photo #3 attached.

My SL has a air vent line attached directly with the coolant expansion reservoir, I hope this will work fine for bleeding.

My Weistec HE masures 25-3/4" by 6-3/4" and has top tabs swept back. See photo #4, #5, #6. The new HE completely blocks the oil cooler intake areas. Photo #1, #2.

Chris,

How tall is your HE? that will give me thought to how much room I need for the oil cooler to function (from your photos in the SL55 Heat Exchanger Group Buy above).

latemodel21

"My biggest problem now is that I have a K-40 radar detector"
I agree ....
ditch that dinosaur and get a Valentine 1 (turn off K and X for california)

the air vent line you mention (shown in yellow in previous diagram) is not from the heat exchanger. One is from the top of the engine radiator and the other is from the output side of the intercooler ... not a big deal in any case (having the HE bleed line)... just something that makes it infinitely easier to get the air out.

the Wiestec HE looks very nice ... also looks like its height may make it impossible to mount the oil cooler out of its way (the PLM is only 5.5" tall). Oil cooler should be ok mounted behind .... not ideal ... but better than stock.

Cheers,
Chris

4 or 5 specific occasions that I can remember - I've had the radar pointed directly at me from the side of the road, going faster than I should, and never have been pulled over or chased for speeding. It works better than I would ever imagine. I like that it is installed into the car as it is effortless to use. I have space to re-install the receiver device on the drivers side of the HE. I will look to see if it is up to date technology wise for sure.

"I've had the radar pointed directly at me from the side of the road, going faster than I should, and never have been pulled over or chased for speeding."

Your reply confuses me... you are talking about a K40 radar detector ... or at least that is the unit that you showed a snap of. It only detects radar (poorly at that) it does not Jam radar.

Radar jamming is a federal offense (FCC gets involved) whereas Laser Jamming is an equipment violation.

perhaps you have one of K40s companion products as well (license plate mounted laser jammer) ... this would be instrumental in stopping police from coming after you ... if it worked. However K-40's laser jamming product relies primarily on technology that is ineffective (and not update-able) . '

I had a k40 system on my first AMG .... I removed it and gave it away. The thing that bothers me most about this company is they refuse to participate in comparisons .... and when their equipment is tested independently ... it finishes last.

People have various favorites when it comes to radar detectors ... Valentine 1 is in every vehicle I own as it is the ONLY detector that tells you if the radar is being shot from behind, in front or the side. AND it is updateable. It warns me as much as a mile or 2 turns before I can be read.

As far as Jammers go, I have Laser Interceptor equipment in both of my AMGs ... and I can say that it works ! and is also updateable.

here is a recent comparison of 3 different jamming systems
http://radartest.com/laser_jammer_test.asp ... note the K40 result (typical). Interestingly, the winner is Escort laser Shifter Pro . This is interesting, because escort used to have their own line, but now is selling relabeled "laser interceptor" products .... and winning


sorry to derail the thread ... but much like Johnson CM30 water pumps, the only people who recommend K40 equipment are either dealers or ... they are consumers who have yet to see a comparison.

Cheers,
Chris

The only radar device I've owned is this K-40, which came with my car when I bought it 6 years ago. It detects the source band type, warns audibly and visually, and tells if the source is front or back. The control is with a key fob remote. It does have "Jam" capabilities front and back which I am told sends the signal back the same as it came from the source. The K-40 system on my car is "fully loaded" and has worked well for me.

The unit states on the device that it is in compliance with FCC rule 15:
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

I don't know the current FCC requirements or how current lazer equipment works and gets its way around compliance issues, but my next query after getting the HE installed will be just that.

Thank you for your help - so nice to be able to come to a site that has the resources to help and make me more aware of the many questions that come up with these cars and all their components.

latemodel21

I stand corrected relative to Valentine's monopoly on front vs rear detection. It looks like K40 has stepped up their product line. I have been skeptical of their products in the past, but I will take a closer look before I shoot my mouth off again : )

Cheers,
Chris

Just a guess, but the FCC compliance is either because it jams with a near zero amount of power, or FCC compliance does not regulate laser output (my guess is that).

Does anybody know if the hose flowing out (blue going up) of the IC pump has an elbow in it? I replaced my pump and noticed that hose was pinched right before the hose clamp on the pump. Mine uses normal radiator hose, but I'm wondering if the OEM hose has an elbow in it to prevent pinching.

latemodel21

I don't have an e55 but I have never seen an OE charge cooler hose that was not molded ....

Mercedes wants you to replace these as a set, it would seem, that looks like this

Attached is a picture of the hose you are talking about off my 2007 SL55. There is a 90 degree turn about 2" off the pump.

Nor Cal SL55

Here's a mock-up of the HE install. I moved the oil cooler back by losing two of the mounting bolts, but it is solid.
The HE is 1/4" behind the plumb level of the bumper support. I may have to trim away on the oil cooler shroud if I have issues with the bumper cover, but it all seems to work at this point.
I need to get a +5" hose with a 90 degree to attach to the OE HE unit and the OE pump hose should reach the new HE. The HE hoses are 3/4" - right?

Jelanib

Awesome, you wouldn't happen to have the part number? I knew it didn't look right when I was looking at it. I shortened the hose to cut out the old pinch but it's still not flowing correctly without the turn.

JoeNobody

Just get a 90 degree silicon coupler and use that

latemodel21

yes 3/4"

GATES makes molded bend universal hoses that work well too (and available all over)

Thanks Chris!
I purchased a couple of hoses from the local auto parts store - one that looks like a question mark to get around the oil cooler line and another with a molded 90 with length to cut. I went behind the counter and picked them myself. I will post up more pics as I progress.

@Nor Cal SL55
going to buy a weistec for my sl55 to how was the install fairly enjoyable and do you recommend it? Or if doing again would you use a different he

Nor Cal SL55

It was very easy. No issues.

Nor Cal SL55

Weistec HE install hoses used. I purchased these at Auto Zone.

Tylerhayles

thanks for the reply bud, and what about relocation of the oil cooler?
