I took some pics and I'll try to upload them for you. I have no idea if it will plug it play, I think it will bolt up though. I checked my c32 and I could only see the connector that connects into the throttle body and not the other portion.

What my plan was to take the rear supercharger snout and modify it and maybe shave it a bit to make it fit. I do not plan on using an adapter plate because there is definitely no room.

I think this is the sl55 80mm throttle body part number 113 141 05 25 . Here's the E55 thread I found for it: https://mbworld.org/forums/w211-amg/...ng-around.html

I can't seem to find the part number for cl600. Still looking.

Here's a few more part numbers:

113 140 09 12 s/c inlet 80mmw/bypass
137 141 07 80 for the tb gasket
113 141 07 80 ls/c inlet gasket
113 140 01 04 for 80mmTB
113 094 02 03 for elbow 80mm
113 141 15 80 for elbow rubber gasket

Hello. I just wanted to follow up.

The E55 throttle body was a drop in replacement for the C32 throttle body.

This was great since I couldn't find a used C32 tb and new ones were ~$1500. A new/rebuilt E55 tb can be found for about $250 online. Used ones go for even less with the e55 guys upgrading to larger ones.

Definitely good to know.

So I was trying to see if it would be possible to do a larger throttle body 82mm+, but I was told I would need to upgrade my fuel in order to compensate for the added air. I think the biggest we could do with out modifying our fuel system would be around an 80mm. I have also been seeing that we could see gains similar to an 80mm by porting the throttle body. Check out the thread: https://mbworld.org/forums/w211-amg/...c_metal55.html

this is what i was talkin about earlier.......

loudandheard

I remember you posting that before, but I was under the impression that the gains would not be as substantial as that of an 80mm because it can only be ported close to 78mm. Then I read the thread I posted about and they mentioned that the flow could be the same if not better than an 80mm, so I never really thought to looking at that until I figured out that I would need some pretty big upgrades to do a bigger tb mod.

So let me get this straight a E55 80mm throttle body bolts right up in a c32?
If so All the e55 guys are selling there TB's lets buy those?

loudandheard

No, the E55 throttle body is the same size as a C32 throttle body, but they can be had for cheap if you need one. What I was saying is that they can be modified to flow almost as much as an 80mm throttle body.

sounds like a good plan

i have installed successfully the 80mm tb of the V12 NA on my C32, i am running it now on the car from 1 week with no problems no codes, the AFR didn't change, maybe tomorrow or next week i'll go to the dyno and see it made more hp or not.

loudandheard

Could you share the part number for the throttle body and what you had to do to get it to work? There was no change in aft at all, not even at full throttle? I don't think you would notice any thing at normal throttle. Could you provide some photos?

part nb: 137 141 01 25, you have to swap pins 1-4 and 5-6 that's all, also i didn't cut any wire, i swap the pins inside the hardness.
i attached pics in the thread " dyno results".
of course when i mentioned no afr change i mean at full throttle at fourth and fifth gear to 150 mph not at idle!

loudandheard

So did you notice any sort of improvement, more responsive throttle or faster acceleration? Was there a decrease in boost from the supercharger? Do you think a bigger throttle body would work better? Would you even recommend going through the trouble of putting on a larger throttle body?

I noticed in the pics you posted in your dyno results thread that the bottom y-pipe connected to supercharger looks like it was coated. Did you have the bottom y-pipe ported and then powder coated? Nice touch with the heat shielding.

I went today to the dyno, attached is the dyno sheet, run 3 is the best run done before without tb, run 5 and 6 are for today, so no difference in power with the bigger tb, slightly down hp.
The boost is the same, AFR the same and hp/tq are the same. the 74mm tb is sufficient on my car.
the bottom y pipe is the stock one, i didn't touch it.

sorry here it is:

Alright gentlemen, I didn't mean to jump into the thread this late but my car has been going into limp mode non-stop since December and I've already replaced the Crank position sensor as well as the Throttle pedal assembly (For throttle pedal position sensor). The last item left is the tb. I purchased the E55 tb & installed it on the 8th. I plugged the male plug from the original connector into the female end of the plug off of the E55 tb. This was because i was unable to reach the other end of the original plug. Either way after the install the car ran great for 1 1/2 miles then went BACK into limp mode.

I've been thinking about using the tb out of the srt-6 crossfire because it is significantly less expensive. (Original quote for $1,300 for C32 tb 175 for srt-6 tb)

Ideas? Any help would be appreciated!!!

Lenin

Ideally you should start your own thread regarding your problem. Unless you are just asking about the SRT-6 TB. Do include any codes that should be stored in your ECU. There have to be some for the car to go into the "limp" mode. These codes are essential if you want some real help.

Did anyone bore to 78mm, worth it or not?

I have the dreaded P0120 so am sourcing cable 1131500028.
Are the c32 throttle body replacements : 112 141 0325, 113 141 0125, 112 141 0125 ?? Some assistance please in correct p/n for an E55/ C32 that is the 74mm. it seems that the 112 141 0125 is a 64-68mm? Some help please? Chhers,

evilsaint

Try the cable first - it's extremely unlikely that the actual throttle body is "broken", unless the cable connection is damaged/bent/corroded where it connects (which you should check out, naturally). Lemme go back and look at my order history to find the P# for the latest revision TB for the 32.

Do you have any symptoms?
