Exotic-metal55

I have searched all over the site and below are the two best threads on the topic. After all this reading, I am still not comfortable on the correct part numbers for the plug and play TB, Y-pipe and gasket.. Can anyone confirm the numbers or clear this up please?

It seems the 2007 SL55 or even the 2007-2008 G55 parts may bolt directly on to the 74mm blower inlet?

Jangy,

Is this what you have? Or you have the VRP kit?

jangy

The new VRP, which may be the same. VRP's original 80mm TB was from an early ('03) version setup that needed some wiring done. I know of 4 that used the parts listed.

Thank you for the info!

One more question. If I find/order the 4 parts below and not get the 80mm SC inlet and gasket; will the 80mm TB bolt on to my STOCK 74mm SC inlet? I would prefer to just port match the stock 74mm S/C if that will all plug and play?


137 141 07 80 for the tb gasket
113 140 01 04 for 80mmTB
113 094 02 03 for elbow 80mm
113 141 15 80 for elbow rubber gasket

jangy

I was going to do the same, but never tried it since it became costly for me (machine shop). I dunno if there is enough meat there, though. The rest is PLUG and PLAY.

JosephLINY-E55

Please pardon the question? Does anyone have approx costs associated with all of the required parts and some assembly instructions or is it fairly easy for any MB Tech? Many thanks from a new E55 owner... Kindest regards, Joseph

jangy

When I was looking into it, my cost for all the parts was $1200 and that was with a minor (maybe 10%) discount. The install is straight forward. Basically, disconnect wirirng, Remove the SuperCharger, undo bolts, reverse. it took about 3 hours total.

Exotic-metal55

So, if you use a die grinder and port match the inlet, what would you say for time? 1 hour to 1.5 only and save 300 for inlet and gaskets? Are we sure the bolt pattern on the 80mmTB will match stock 74mm SC inlet?

rflow306

You need the new Kompressor inlet the bolt pattern is different, the stock inlet can be used but it will require some machining and welding .

jangy

NO!! We are not sure!! If I remember right, the inlet was too thin walled to do it, but I do not remember. Yes, I'd say 1 - 1.5 hours to port match and polish.

If anyone is buying the parts or has access, maybe they can test fit? Most of these parts can be returned.

jangy

Thanks for the reply. what kind of welding? Is it to add a piece on or to actiually weld parts? Also, I think I remembered that part being fairly cheap?

Thanks to Vrus, link below.

His later tb kits had the amg 80mm inlets with the bypass valve hole.

Exotic-metal55

The part number for the 80mm TB listed above from Jangy ( does not have the PCV inlet on it and the butterfly opens bottom of the TB,, not the top like the stock 74mm. That being said, is the below info TRUE about the wiring too?


This Y pipe part is also the same part as the stock 74mm pipe and will not fit the 80mm TB..


Is there a trick to make this a plug and play? Are the wires the same? how can you work around the PCV not being on this part number and valves opening opposite? Some of the tuners must use a different 80mm tb and not the one from the 07 Sl55.. They seem to have the pcv on theirs..

jangy

I have a spare 80mm y pipe piece, so I'll check it. Also, I'll get the full scoop on all the parts and the install.

Exotic-metal55

Thanks you have a PM..


Any reason everyone seems to be keeping all the 80mm TB numbers secret? It seems there are at least 4 different 80mm TB`s to choose from. Not sure how may are plug and play (no altering wiring pins) ..

These are all just off the shelf AMG parts and be nice for the forum to get together and come up with an accurate list? Am I wrong in asking here?

I will be glad to post all the pictures and parts I have.. Even what I learned from these parts in just a few days. Just trying to get the 80mm on so CAM`s and tune can follow before it gets cold...

jangy

No, you are right and also it is nice to know I wasn't off on price.

There are a number of TBs. They had them in the maybachs, then I think a few early 55s had them and now the the SL (last of the 55s). There are likely more.

I have the VRP (newer version) one and some parts from the '07SL. I'll look to see if I can see part numbers. I remember that there was going to be an issue with the CF airbox fitting on the 07 SL55 setup, so I don't know how the configuration went.

I bought a throttle body and adapter a while back and have not had it mounted yet. I didn't see a number on the TB but the above number is the one on my adapter. It is supposed to be Renntech.

Exotic-metal55

Thanks for the inlet number.. That seems to be a very consistent number for the inlet.. Does your 80mm have a PCV (1/2" pipe) under the botom of it like your stock 74mm tb? Can you tell what side the butterfly opens from? Top to back or bottom to back (Back=towards inlet)?

jangy

OK, I only got a little data. There were indeed a number of 80mm (or so but all called 80) TBs that MB had, BUT only the one from the '07 SL55 is a plug and play as it is. All of the others need to be modified. The tuners do the modifying.

While we are getting so intimate with this, has anyone looked at that area to see what the absolute largest TB openning could be supported by the blower inlet?

waxking1

There is a 1/2" pipe on one side. The butterfly opens inward on the same side where the pipe is located.

Exotic-metal55

I will mic. all this next week. Of course a larger s/c inlet could be easily cast once someone makes a nice 90mm plus TB for the 55..

Exotic-metal55

As promised, I mic-ed the TB (inside and out) and the Blower inlet openings several times. If you were to machine out the 80mm inlet, 86mm would be as far as I would go taking that route. As people port heads and add more aggresive cams,, then a larger TB will make a difference. If you molded a new inlet, then a lot of creative things could be done, including improving the air flow insdie the inlet, not to mention adding a larger aftermarket Throttle body. It is all manifest destiny!!

If a 90mm TB came on the market for the 55, then a plate could be welded onto a machined out 80mm inlet and adapt 90mm TB to the inlet. Could be a nice kit , if done properly..

The current 80mm TB has "virtually" no room to be opened up.. With a lot of carefull machining and some hand porting,, 2mm may be possible at most out of the current 80mm TB.. Not worth it.. IMO. I say 2mm , as I came up with the butterfly only being 78.4mm.. The flanged edge of the TB is 80mm and just inside it goes to about 79mm.. The actuall butterfly is 78.4mm. per my digital Mic.

We are only talking about a hole that is barely over 3" that feeds the entire car. How can that not be a restrictive point? I'm trying to deal with 3" tubes on each intake side and 3" tubes on both sides of the exhaust but just can see how getting enough air to give a solid top end is possible without better airflow.

Exotic-metal55

80mm TB can flow around 965 cfm! Yes, through a small 3" hole There are a whole lot of other factors to consider before doubting that 3" hole. You can put 5" TB and large exahust but if the heads /valves can not take the 965 CFM capability of forced industion,, then it is all a waste.

Most decent tuners can calculate and even measure if 80mm is enough for your combination pretty easilly. There are 500 CI motors with super chargers making opver 1000 HP off of only a 90mm throttle body. Your bore, stroke and cam event duration also comes into play on being able to stuff the CFM capability of a 80mm TB above 5000 rpm.

It is highly possible that the heads/ valves and cam could be the restriction and not the TB,, at this point. Here is another area to consider.. The blower inlet that you changed to 80mm. It has a HUGE cast venturi in the mouth of it to direct air flow into the SC? Can that inlet handle over 965 CFM? Lot of areas to consider before picking on that little 3" hole

I am curious to find all these answers out as well, before specing custom cams and having custom head work done.
