Weistec update
Well after a long wait the the car is almost back in my hands. My new HREs arrived yesterday and when 305 rear tyres arrive hopefully on Monday they should be on the car. My DTM rear spoiler is going on this weekend and the Weistec supercharger has been installed. I myself have not heard the car at all but have been told it sounds beautiful. I am meeting the installers at the dyno this afternoon so will have some dyno numbers. Sorry dodger63 but thats all i have time for at the moment!. No 1/4 miles yet
At the very least i will have some baseline numbers to compare the gains made by the supercharger on a totally stock 63 engine.

Ok guys the numbers are in!!
I don't have the dyno chart yet but hope to get it soon and will post so you can see the different curves - i have yet to see them myself as i had to leave before we could even start the dyno
Anyway here are the peak numbers at the wheels from the before dyno:
Torque Power
Stock: 513Nm @ 5300rpm; 309kW (418hp) @ 6500rpm
This was done on a dynapack dyno and we therefore lost around 17-18% through the drivetrain versus the official crank numbers for the CLK BS as published by AMG of 507hp and 630Nm.
After the installation of the Weistec supercharger the numbers at the wheels looked like this:
Torque Power
S'charged: 669Nm @ ?? ; 385kW (517hp) @ ??
Working back to the crank numbers using the drivetrain loss 17% from before yields peak numbers of ~806Nm and 464kW (623hp). Weistec claim the Stage 1 system will get you 747Nm and 626hp so i was bang on the estimated hp number and presume that the extra 50Nm of torque vs their stated peak number is possibly due to the new tune i received for Australia's 98RON fuel. What ever its due to, i aint compalining
I guess the outright numbers are not critical, we are all more focussed on the incremental gains from such mods and as you can see, they are pretty reasonable at 25% increase in power and >30% increase in torque.
Recal that this was on a Black Series and whle the peak numbers wont change, those members with a C63 will get an even bigger incremental gain
The car drives like a dream!!! I am told by the dyno operator who has nothing to do with Weistec or the team at Ramspeed in sydney who performed the install that the tune was perfect in all respects AFR etc. PM me or post here if anyone has other questions regarding the Weistec supercharger.
I believe that these are the first independent numbers published for a STOCK 63 car with a supercharger and hope other forum members find this helpful.

Ramspeed actually mounted a camera above the car I'm their workshop and have reduced the whole procedure into a minute or so time elapse video which I believe they will put in YouTube.
I will have more pics etc when I get the car back next week, by then the new wheels and DTM wing should be installed and I will definitely put up additional pics

Dynapack dyno has least amount of parasitic loss vs ANY other dyno as they remove your wheels & bolt actual dyno to your hubs eliminating hp/tq losses due to actual wheel weight & varying losses in actual wheel/tire diameters easily add extra 25+ rwhp & rwtq using Dynapack
http://image.modified.com/f/29496309...apack_dyno.jpg
The normal drivetrain loss on say a DynoJet or DynoDynamics is 17%-18% as the wheels/tires are still on the car vs Dynapack actual loss is much much less ie depending on what % dyno operator is hopefully adding back to account for removing wheel/tire part of real world rwhp/rwtq when vehicle is actually being driven etc..

i love to see your car in action ,live,0-200km/H etc. theres a clip on youtube by some RADWAN that shows what he claims is a e63 amg weistec supercharged,it goes 0-200km/h at about 14,5 seconds , http://www.youtube.com/watch?v=90uFVzXu93E ,thats exactly the numbers for a stock e63?????i base my buy of a weistec supercharger on your acceleration results,please let me know as soon you get the car
