My understanding was the BS had a few more things that reduced weight. Seats, Door panels, wider fenders. The benefit of the CF on the roof is the lower center of gravity for the car by reducing the weight at the top height of the car. While I understand that removal of all the hardtop motors reduces weight I'm not sure it was a good thing. The F/R weight percentages must get even worse.

There are other small things like a difference TCU program for the tranny.

As to boost on the 5.5NA motor ... all of these boost kits for stock motors are running less than 7lbs boost. Thats why the modified 5.5 FI motors can make so much more HP. THey are running at MUCH higher boost lvls.

Regarding Dan's engine ... your looking at brabus specs for just the displacement increase. Dollar for dollar the supercharger kit from Kleemann and Renntech are cheaper per hp than the displacement increase.

Heh my wallets weren't as deep as Dan's and also Brabus never told me about the 6.1 S ... DUH.

BTW Dan,

Anyway you could send me the TCU program from a blackseries SLK55?
