I was on the way to the Dallas Stars game the other nite and saw a very interesting red car approaching from behind. I slowed to let it pass and get a good look. It was very red and incredible looking. It was clearly based on an SL600. On the rear it was marked SL900 Kompressor. The body/spoiler mods were truly spectacular and the sound that came from the engine was beyond description. I thought it might be a tuner car, but I have searched and search and haven't found any reference to anything remotely matching it. I would fully expect this car to be able to smoke a Lambo. Anyone heard of anything similar?

As far as I know of have ever seen/heard/read the DOHC V12 can only be taken out to approx 7.3 to 7.4 liters of displacement. Perhpas someone had supercharged a SL600 and turned the number upside-down? I don't know of anyone who does superchargers for the M119 V8's or the M120 V12 but just about anything can be had at a price. I have always been told by everyone, that turbos or blowers wont fit underhood of E or SL cars. I believe you saw something quite unique but I have seen many poser benz out there. One of the most common is badging a SL320 or SL500 with the SL600 and V12 emblems. Something akin to all the bimwads putting ///M badges on their non-///M cars. (that means YOU 325i owners) I'm sure the owner reworked the exhaust system pretty heavily. The "Bad Ass Benz" Renntech V12 had a very impressive exhaust note... Every tuner car I have ever seen had enough badges to make their idenity quite clear. (even if the owner removed the badges, little things like muffler tips or front air dam plating would be a giveaway) Any tuner capable of creating something like that would surely want to leave their "mark".

My best guess would be he had a custom exhaust, flipped the 6 to read 9, and plastered a Kompressor badge on to boot. You should of followed him to find out what it was! Line up next to him at a stoplight, if he just wins...its a SL600 with some small toys...if he goes off like a 10 second NHRA car then I could be wrong.

This car was clearly done properly for both the suspension and the body work. I would have guessed a sticker price of 300-400k from what I saw. There are alot of details I noticed that indicated a complete conversion of the car rather than someone just sticking a bunch of aftermarket pieces on. Even the non-car relate details made me think it was for real, older guy driving with very good looking/younger female passenger. There is plenty of money in the area and stuff like this pops up now and then.

There is no tuner that offers anything over 7.4 liters. The 900 portion is obviously something he dreamed up. The supercharging is viable and Lorinser sells them. They have just come out with a new supercharger for the new 5.0 V8.

Lorinser, who bought Mosselman, offers superchargers for the new SOHC 3-valve/twin-plug engines, but I have been told they do not offer anything for the M119 DOHC V8's or the V12. Before Lorinser bought Mosselman, Mosselman tried to do some prototype forced induction kits for 400E/500E's. They were never able to make it work without either hacking the car to death, having massive lag, or both. I knew an individual who had the "donor" V8. According to him there was not enough clearance on top of the engine for a supercharger and not enough clearance between the engine/frame rails for a turbo. A centrifugal supercharger to up front was also dropped but I don't know all the specifics. Just about anything can be done for enough money, but it seems there is no practical way to use forced induction on a W124 V8. W129's seem to be just as tight a squeeze so don't count on anything there. If this "SL900K" was anything, I would guess a SL500 (SOHC variant) with a blower, some exhaust work, various small goodies, and BS badging. More likely it was someone who bought cosmetic bits and had more "bark" than "bite".
