so meassured 2 65 amg tbs today and found some confusing things.
in epc the following part number is given for the 65s: 2751400104.
so checked 2 65s one one the normal 600tb was fixed (2751400625) and on the other one (2751410086 with amg writing on the cover).
so anyway both had the same outer diameter (85mm) and the same inner diameter (79mm)
and now?
any other proofs for the 65 tbs?

When I got my LET tune I asked if they program out the torque restriction, they said yes. VRP says they do it too. Since much of the talk on MBWorld recently concerns the claim that the ECU and TCU work together to restrict torque in some way, I speculate that LET and VRP do it by keeping the BP valve closed.

Until then we're never going to see the maximum power from our Kompressors.
You're only as strong as your weakest link.
Yes, dual 74 mm would be awesome!

Since Vadim let the cat out, adding a second TB is actually very realistic and avoids the issues we are having with the electronics.
I have been looking for a way to get a larger TB for a while and Vadim once suggested that we try the double TB. It would take a modified or replaced plenum and an extra TB. It is an easy enough test fit so maybe we'll try it.
As far as a larger TB, the hardware is easy to get, but I still have not come accross anyone that is willing to work through the electronics. Two guys are saying they have contacts and so we will see.
I really don't think it will be much longer before we see some higher level of mods for the 55k. I find so many companies doing work on them. It is mostly exhaust, which is likely the LEAST bang for our Buck, but marketing is marketing and it seems that all tuners think a cat back is a no brainer...

Although Finny is right on the ball---price per gain is somewhat small considering the price involved.....$2-3k
That said, as Andy mentioned---any improvment on PD blower flow will give you power. Vadim just posted some hard proof. His "FANGS" intake mod---which just opened up the flow of air from the fliter to the TB gave him 12-20rwhp. So a stock car that swaps out their stock intake and inlet system for a 90mm TB and "fang"-like inlet might get up to ~40-50rwhp.
Personally, after running the numbers for SC discharge temps and the low eff of our IC's ---I would rather get the highest HP possible on the lowest boost. I'd like to see what my 420whp stock car will get with bigger TB + Fangs-like intake +headers and proper software that will keep the bypass valve closed. I suspect that combo will make 500whp+ without the drawbacks of the pulley.

I'm hoping to drop the psi and keep the larger pulley.
I was thinking more about the true potential of this and 2 things come to mind.
First, MB places the wire supports in the air tube parts so that the tube does not collapse under negative vacuum. Also, we had the spell of many green filters getting literally sucked out of the seal in the airboxes. This tells me that there is some restriction, especially on kick down or WOT. If we reduce this restriction, wouldn't it hold that we would be reducing the overall psi of the system?
Also, I find it interesting that the E63 runs on 2 TBs, each of which is MUCH larger than the one on the E55k.

i cant wait to see these results! twin 74mm TB, 94mm or whatever else is being worked on.
i guess im really going to have to get rid of my VRP CF airbox if i want to go bigger than 80mm for the throttle body huh?
