For everyone that is planning to go to a 82mm throttle body for your M113k/55 AMG. You will need to replace all the old seals and gaskets from the supercharger with new ones. I didn't the first time and used the old seals and gaskets. I had CEL code p0505 the whole time. I finally got feed up and did it the right way. Remember our cars are over 11-14 years old. They total to just around $60-$100 depending where you get them. Also get a new map and IAT sensor. Silicon used Permatex Ultra Black on all the gaskets and under the adapter plate of the 82mm throttle body.
I disagree with using the that black sealant the better one to use is The Right Stuff it seals better and works faster but I would only use it on the supercharger to the intercooler connection that doesnt come from the factory with a gasket. You can buy the gasket for it but most recommend not using it and say it seals better with the sealant .... having tried both ways I say the sealant way is much better. Just make sure that you clean both surfaces very well use a blade to get off any excess sealant that is left over and then clean with a wire brush and lastly prep both surfaces with brake cleaner. The seal for the bypass to the supercharger is a MUST, this seal gets old, hard and brittle after all the heat. Take this time to also clean your intercooler of oil that has contaminated its vanes ... this lowers its efficiency spray some brake cleaner in there and then rinse with water til clear.
As for the other gaskets I dont think I would use the right stuff on those I prefer to use good old copper spray gasket on both sides this provides a very good seal and not as messy and less likely to smear off when mounting the parts together. I have done several of these and never had a leak, and when you need to disassemble there is almost no cleanup compared to sealant on everything
I have re-used my bypass gasket multiple times and just applied a light oil smear to to let it slide into place and not grab the o-rings and move them out of position. I use silicon instead of the gaskets at the tb, adapter and intercooler. I also re-use my surge tank gaskets with no silicon. I have no leaks, idle problems, CEL, surges or hiccups.
If the bypass tb seal is flexible and not hard, reuse it.
Also instead of the good ole reliable permatex red, black, however you like your girls. I would recommend
petroleum resistant and 10-20 dollars can't recall
Anyone know the part numbers for 24 and 74? Hoping to do this install next weekend
I use GenuineMercedesParts website for this kind of stuff. Here is a link to our engine and you can pick which part of the engine from there. Lays out a diagram similar to above with part numbers: https://www.genuinemercedesparts.com...-v8-gas-engine
Are you guys using bolt-on adapter plates or did you weld? Wondering if that makes a difference in how likely you are to see problems.
I’ve only used it with the bolt on adapter plate. I put the silicon gasket maker between the snout and the adapter plate. Let it dry and remove any excess carefully.

You got a leak,,I know you hate to hear this but you do..You need a proper smoke tester with high psi and to be held for 5 min to fill the system wit smoke.

I’ve had a feeling but here’s what I don’t understand, maybe you could help me understand. If I have a leak why doesn’t it do this on the stock throttle body? I’ve had the P0505 code come and go on the stock throttlebody probably once a month but it never goes lean and never throws the p0106 and never goes lean.
