...........thanks. I have a TB from my G55 that I removed when I upgraded to the Kleeman 80mm TB. I was about to sell it when it occured to me that I may be able to wap it into my s/ced W210 e55. I wonder if it can be a direct swap. I'll ask Rich.

..........JamE55, in an old thread you mentioned that you were doing a TB upgrade. Is that completed? I am looking for a completed kit. I also don't mind having my car used for R&D if the labor can be free. I already have the part.

..............best answer is that I do not know. The W211 E55 guys are getting 15 or so RWHP from the TB upgrade, but their cars are s/ced. I am not very knowledgeable about this and I am looking for someone who has some first hand info. I can only imagine how much it will cost if it was done experimentally at an hourly labor rate, especially if custom fabrication is required. I thought JAME55 has had this done, but I'm not certain. Maybe He will chime in.

Maybe James should head to the dyno and post up his sheets.... 
I am running Kleemann s/c... if the price is right, I'd do it for 15 whp... as long as driveability is not sacrificed. Keep us posted, Ted.

Ok..... if the TB is enlarged on our NA cars, should that make any difference UNLESS the amount of air is increased? Meaning even if putting a larger TB on our cars with the stock air box, that shouldnt yield anything , right? I bought a new OEM TB recently and I was going to experiment with porting/polishing it given that I still have a stock air box...any thoughts?

There was an old member "grumpy666" who knew some pretty interesting stuff. I recall he once wrote about how to tell if a TB was properly matched to a motor. I don't recall if it was applied to N/A testing F/I or both. However, if I remember, it was explained that intake vacuum should be tested at the TB during acceleration to WOT. Our TB's actually have a nipple which would allow this.
From what I recall a properly sized TB should show only the slightest bit of vacuum when the motor is running at WOT, showing no restriction. Where a smaller TB would introduce restriction as sizes got smaller which would be seen as intake vacuum measured at the TB port.
I could be way off with this, but I remember reading it and it makes sense in my head.
I've got an extra TB from an ML55 if anyone wants to play with it....

Anyone want the ML55 TB I have to mess with it. I'll let it go cheap as I keep moving it from drawer to drawer in the garage. I think a few people here had their TB's ported a while ago.

Throttle body is usually one of the last modification you do b/c it requires a decent amount of airflow to net any legitimate high end gains. The gains are always in the last 1000 rpm of the powerband, they prevent the power from dying off as quickly after peak HP is reached, usually the power will just level out instead of falling off, or might even keep going and peak at higher rpm (depends a lot on intake manifold and type of cams the car has).
74-80mm will probably net 5-8 wheel HP on a lightly modded E55 AMG. SC is totally different animal so you can't compare that to the NA 5.5Ls. You probably won't truly be able to unlock its potential until you get high performance headers, X-pipe, high flow filters and some other stuff as well.
Keep in mind though, usually throttle bodies require software upgrade b/c the amount of air entering the engine is significantly different and it can cause you to run a lean condition. The ECU might be able to adapt... it might not
it will of course sharpen up throttle response as well but b/c the cars are autos I don't know how much of that will really be able to be felt
I'd save this mod for last, but if you have aftermarket SC on your car or alot of mods, this one is for you.
