Does the E55 have a different throttle body than the C32. I'm not 100% sure, but I thought the C32 had a 74mm throttle body and the E55 had the same. Can any one clarify the differences for me?

Your title is a bit confusing

King320

yeh, i read it three times trying to spot a difference.

there the same size but there different throttle bodies. I believe we have the same throttle body the older cl600 and s600 cars. If you put in the old part number it shows up on parts.com. If your throttle body is bad, you can get it rebuilt for around $250.

I picked up an oem E55 throttle body, plenum, and Y pipe for a great deal recently. I was originally looking for an S600, but I found this for a great price. I figure it if it fits, maybe I can have it bored out 78mm or 80mm just like the E55 guys, but I didn't want to take the chance with mine just in case.

It does fit right?

i dont know. The e55 one looks distinctly different, so i didn't want to take the risk. So i got a s600 for cheap on ebay. It looked exactly the same as the c32 one and it worked fine.

Is the S600 one 80mm, I think that's what I read. I didn't see any s600 throttle bodies on ebay when I was looking. We'll see how this goes, would be nice to have a mod like this for a good deal.

here's the part number A 113 141 01 25. If you put it into parts.com without the A. It'll list all the cars with the same throttle body. The 2001-2002 s600 has a compatible throttle actuator. Honestly, i would just get it rebuilt by bb reman for $250.

Here's my original thread.

you can probably just bore the stock throttle body to 78mm and supercharger back shell that the throttle body attaches too. I know tvt was boring the throttle bodies for the srt6 guys. I'm pretty sure they can do it to 78mm. You might want to PM them.

look at maxbore.com they can bore your t/b for 125$ and its a fantastic job complete with new butterfly

From the research that I've done, the S600 throttle body is 80mm. I'm thinking that the E55 would work if it will fit. The box on the side would definitely make it more difficult to install.

The E55 has same throttle body as C32, the 600 throttle is 80mm but it will not work with our car, the only one that work is the SL55 2007 one 80mm(113).

So im little confused since i am researchign on what i need to buy as for a throttle body, Someone said the 2001-2002 S600, Then someone said the E55 one... What only concerns me and im sure other members as well are the electronics. I know there will need to be some custom fitting like what Fluid Motor Union Did https://mbworld.org/forums/c32-amg-c...mg-teaser.html
He stated he used the S600, so the question is what works with the electronics with the C32 meaning its plug in play as far as wiring goes? Altering the plenum is not to hard.

TemjinX2

This is what i got, when i put in the part number awhile back on parts.com

loudandheard

I can't find that page on parts.com, love that site by the way.

I'm going to mod the E55 one and see if it works, if not a lucky E55 member is going to pick up a modified throttle body on the cheap.

this is what you want:
80 tb 113 141 05 25
80 y pipe 113 090 03 29
80 sc inlet 113 140 09 12

I still do not really understand what a large throttle body does.

From what I read it's suppose to increase flow, so more horsepower? This mod only works well with the conjunction of other mods? Throttle response increases as well?

E55 (w211) has a different bolt pattern, it is splayed and not square. You can get 78mm out of the stock C32/C55 TB with boring and a new butterfly, but that is the max as any bigger and you interfere with the manifold opening.

We will have our C55/C32 78mm TB tested in the next week or so (extremely busy summer) and will post results. Pricing will be $250.00 plus $75.00 core charge. We will offer GB pricing.

interested. please keep us posted.

Also interested.

Definitely interested if there's power to be gained.

So as an aside and somewhat related piece....what do the other AMG's gain from TB mods? Common on the E55 and SL55's I know...that should give us a yardstick to measure by at least.

jturkel

i'm gonna guess, depending on mods, fuel (if you're already running lean, you may need more fuel) and after tuning, somewhere between 10-15whp

TVT_DESIGN

That pretty much sums it up. The more the intake and the exhaust are opened up the better the TB will be. This does not necessarily mean a larger pulley car will benefit more then a smaller pulley car though, more in how it breathes.

here's my TB and part number on it. forgot what was the reason dealer replaced it under warranty few years back.
