Weistec Engineering M113K Supercharger Upgrade...Progress
I think the early adopters here will get the best deal, selling their OEM supercharger.
It's all about the delta.




Weistec if your listening I would buy this at >5K tomorrow...
The Best of Mercedes & AMG




+1 about $10k + installation.

I'm hopeful that Weistec has been as thoughtful about the E55 market as they have about the design itself... clearly, a $15,000 supercharger "swap" kit for a used E55 that routinely sells now for maybe $25 - 30K is a total fail.
Admittedly the dyno graphs on their website for the E63 show massive gains over stock, but that is to be expected when adding a SC to a normally aspirated car. The power increase for the E55 is likely to be a lot less dramatic.... though I'd love to be proven wrong on that one.

It's all speculation without some pricing and/or power numbers..... but their own post indicates that they "get it" about being affordable and competitively priced.
Unfortunately at this moment, there appear to be a number of aftermarket "power adder" initiatives being developed on this forum (Evo's TMC, smaller SC pulley, cold air intake, low-cost airbox / python tubes, etc) and it doesn't appear that any of those mods are going to be compatible with this one.
Additionally, the guys who have already dumped several thousand dollars into traditional Stage 1, 2 or 3 power packages may already be "in too deep" and won't be able to justify spending this kind of money for an incremental improvement in HP over what they already have.
It's possible that most of the common upgrades will also work with this new setup: (headers, larger TBs, cooling mods), but there will probably be significant restrictions on the crank pulley sizes that will be supported, and based on how the TB attaches on this new design... anything intake or airbox related is probably going to get scrapped to get this system installed.
Just a few random thoughts to consider....

E55 guys already got LOTS of options to make big power, and there IS price competition out there on the E55 platform. The "money-no-object" guys aren't driving E55s anymore... they've moved on to a newer platform and will happily drop $10-15K on mods. In the larger AMG picture, I understand that I'm just a "bottom feeder" now. Vendors who still want to tap the E55 market successfully can't keep charging "baller" pricing for mods on this platform and expect to sell anything.
EDIT: Gaspam, missed your last post while I was trying to put my own ideas together... I think there are some significant differences between the E55 platform and the ones you listed. The "all in" price (car + mods) seems to be lower than the E55 which I think is significant, and the cost/HP-gained ratio for those guys makes it easier to justify spending big coin on a blower installation.

for a new person to the e55 that doesnt have pulley, headers, TB, etc... a straight $12K single mod that gets them to 600+whp might be a bit more appealing than piecing together many mods to get to 500whp.
and i think with prices coming lower and lower on the e55 you will see a lot more people in their early 20s coming into them...
same thing happened in the audi world with the twin turbo s4's... no significant HP mods until about after it was 5 yrs old and then all the stage 3 kits came out nearly doubling stock hp and then after the b5 s4 model was like 7yrs old you started seeing all the GT and tial turbo kits coming out that tripled/quadrupled HP over stock...
its just the nature of the game, the older a car gets and the cheaper it gets, then the more mods come out for it because more of the types of guys like you and me that want to mod our cars, can afford them now

The E55 may be in a bit of a transitional period. It's still a tad too expensive for the youngest enthusiasts. You can still get a full-warranty and banks will still finance them (mostly) at the current asking prices...
Before much longer, there won't be any such thing as a 3rd party warranty... almost all of the cars out there will be have 80,000 - 100,000 miles on the odometer and the prices will be falling fast enough that people may not need financing to pick them up anymore (at least not 100% financing)....

If they are using their own supercharger they have the supply of parts just modding and few things like software and adapters to make it work.
As far as platform there are other 55's besides the E so a lot of people might be on board.
They know that it will be a hard sell if they go over 10K.
The 63 kit is a totally different beast N/A and new software to write or learn to write.
Our 55 software is known and there are many files out there for it. And examples of what to do and what not to do.
I just wish they would throw some numbers out there to stir the pot I'm not talking prices in the ballpark but maybe the parking lot.

the perfect storm for new high HP mod developement




I do see the point of being "in too deep", but many of these mods that many have already done, need to be done to support such a high hp engine...
