82mm TB for C55
I'm having an 82mm TB installed on my car by Vadim. He told me if there is enough demand that he would make a kit out of it which includes a custom intake system to match the much wider diameter.
Not sure if NA'd C55s would be interested but it would sure pair up well with Hooley's long-tube development. More air in, More air out.
Any interest? Stock TB is 74mm. Big difference in how the car will breathe.

I'll post pics when it's done. As of now only Renntech started selling the 82mm TB kit but the price is ridiculous. Mine cost less than half of that.

Just curious, is the opening into the intake manifold (where the tb mounts) on the NA m113s 82mm?
The opening on the m112 intake manifold is only 74mm, hence the recent movement for 74mm throttle bodies on NA m112s.
I figured the intake manifold would be similar between the NA m112s and m113s? This would also imply that the NA m113's ID on the MAF is larger than the 74mm ID on the NA m112 MAF also?

I guess my questions aren't so much for the sake of the C55 crowd. Ive always been curious as to what parts would be interchangeable with the NA m112.
I'm no pro at this, but how much sense does it make to make your throttle body larger than your MAF's ID?
How large IS the stock ID of the MAF on the C55 (m113)?
Ya posted at the same time I posted. I cant quite read that pic, what are the numbers on it?
Thanks!
edit: wait... we know the stock tb is 74mm, how big is the ID of the MAF? Thanks again...

How will an 82mm throttle body fit on the intake manifold? I just happen to have a few of these sitting around. My garage is turning into a Mercedes used parts depot.

You can only go as large as the intake manifold opening itself. Some Mercedes have a much bigger opening on the intake manifold than the throttle body, others don't and are pretty much the same. You could always machine the opening but that's labor intensive and costly.
Furthermore, if you go too large on the opening, you have to then get special software specifically for that TB simply because the ECU can only adapt to so much new incoming air. All of these are key factors, furthermore the throttle bodies are one of the last bottlenecks on the AMGs and this should only be a mod of last resort (meaning you have put every other possible bolt on mod first and you have nothing left to do). If your car is lightly or even medium modded, it is simply not worth it (at least on NA applications).
just being honest.

That thing your holding looks vaguely familiar to what's sitting in my garage as well.
A good point though...as NA'd C55s would need further mods but Vadim says he wants to make this a kit if there is enough demand. I can measure it tomorrow and compare it to your measurements. I believe the opening is 78mm which would be fine for 78mm kit but not 82mm.

To chime in on AMS's comments about needing retuning with larger (than usual) throttle bodies that require opening up the intake mani... I just figure if I am going to install a new intake manifold, why not spend the time/effort to open it up a bit to prepare for an even larger throttle body + retune since it would be one of my last mods anywhoo? BUT if the MAF's ID can not be increased, then this would be completely moot
Thanks for chiming in fellas.

Edit: Just measured it myself this morning and its 3 inches/74mm all right. Vadim can open her up easy though.

You talking about the 82mm TB or the car? I think you mean the car right? It will be in the low 10 seconds 1/4 ET at over 130mph therefore will break the all-time MB dragtime record this June with just the SC. After the bore, stroke and TT, this will be into the 9's by Q4-2009.

No doubt accounts for a fair portion of their relatively broad torque curve.
Shouldn’t be too much effort bore its opening for a larger TB – mounting stud spacing permitting.
Snazzy shoe you’re wearing, hooleyboy.

Trust you’ll continue to keep us updated with its progress.
