Weistec Supercharged M156 , Results & photos inside









Trust me when I say the car has transformed into a beastly monster. The most amazing part about this supercharger is that the quality and tone of factory driving has not changed bit. It is truly a A+ upgrade.
I already had LT headers + ECU tune + catless pipes and my car was making 465rwhp. This graph doesnt show the torque value, because initially I did not know where the RPM sensor should have been placed and thanks to mbworld member "Mthis" I learned where the location was. Here is the previous dyno results without the SC:

After the supercharger installation. I recieved the Weistec Stage 1+ tune for my ECU and I hit the car hard after about 100km just to let the SC system adapt. I took it again to the dyno and this was the result
:
All my pre and post dyno runs were done on 4th gear. Maximum HP reached 603 RWHP and 546 ft/lbs RWTQ. I gained about 138RWHP at the wheels. I am really happy with how the car preforms. It was shooting flames at the dyno. I am compiling a video and will post it pretty soon.
I am really excited with Weistec Engineering with the way they transformed my SL63 into a brutal beast.
Enjoy your new power.
If u have trouble spinning the tires drop the top to add some weight to the rear

Are you going to paint the heat transfer/intercooler rad flat black so it disappears behind the grill or leave it as is?
The SL is a sick car. Maybe for my next toy. I am messing with something else right now that I just picked up. That is why I didn't mod my C63 any further. It was mod the C63 or get another toy. I choose the toy and keep my lowly "Tune Only"
