Hello guys,

Ive just come across this website.

http://www.xtra-power.com/index.php?...roduct_e63.php

Its a tuner that fits kompressors on the E63 AMG, boasting power goes up to 660 hp and 595 lbs/ft of TQ.

Anyone know anything about them or have any info/feedback regarding such a conversion?

Mmmmm..... Sounds interesting.

I emailed them and got some more info. Here it is:

1. MCT gearbox on the w212 is able to handle the extra torque.
2. ECU will not be remapped, as the kit comes with their own "ECU box". (Which I assume is a piggyback ECU?)
3. Kit does not include an exhaust or manifold.
4. Kit includes the following:
•Eaton Supercharger
•Complete Xtra Intercooler system
•Servo brake fluid container
•Complete belt system
•Xtra Fuel rails
•Complete intake manifolds
•Xtra ECU

However, I know that the 6.3l AMG engines are already very high compression and I thought bigger cylinder heads would be needed for any forced induction. However, I think all these guys do is use 'colder spark plugs', does that seem safe enough for the engine?

Xtra Power and Weistec both have supercharger kits available for all 63 AMG models. They are more known in the C63 section of the forum due to all the threads started about them in the past 3 months or so . There are a couple of members who will be installing the Weistec system soon and will review it completely, which may help you make a decision

That would actually be excellent, to get some feedback off them. I think I should start looking at the C63 forums a bit more

Evosport is installing Weistec's on JrCart's and eCambell's Black Series. I believe they are picking their cars up on March 26th and will heading down to the Benz meet at the Hooters in LakeForest, CA.

Man, hats off to any of you who would consider strapping an S/C to a 6.2L. That motor seems so high rung in N/A form (High Compression, masterfully engineered to be close to all it can be in N/A form), and assuming internals are not forged, etc., it seems like something you'd wanna be careful about.

The good thing about a supercharger, compared to a turbocharger, is that the 6.2 will keep its legendary exhaust note and most likely improve on it with the extra air being force-fed into the cylinders

How much is the kit ? interesting that 7speed tranny can handle this massive torque !

Poison

I got quoted an approximate price of 24k USD.

K-A

That cheap? Lol.

Poison

Well that price includes shipping, taxes, and installation in my country as far as I know :P

Racing Dad

OMG!! R you serious? Then it definilty includes more than just the SC. Well, at least i hope so. Maybe some new pistons / piston headsmm or at least a spacer to bring down the CR.

Then you can turn up the boost a little. How intresting... that's a little out of my price point. I would trade in my car for a brand new one and probably pay about that much in difference.

24K !!! That is crazy id rather go with a 2k nitrous kit or even better sell my car get a new TT 63 and do a tune and make as much power and about 100 more lbs of torque .

Racing Dad

FYI there is's a moderately more affordable version now that is $14K

Still not cheapm, but relatively speaking, it's an improvement.

otakki

I'll pass on that.

I concur with eurowerx on rather go on to a TT 63 instead for the same price.
