SPEEDRIVEN is proud to present this new, 750 + hp (91 Octane) tuning program for 600-series V12 Mercedes-Benz (2003 +). This is a powerful, responsive series of bolt-on performance upgrades that improves horsepower and torque without sacrificing drivability and smoothness. In “comfort” mode, the V12 is whisper quiet and nearly invisible – just like stock. In “sport” or the new Speedriven-added “manual” mode, the Mercedes powertrain takes on a more muscular personality, with the big, biturbo V12 charging towards redline.

Massaging the Mercedes-Benz biturbo V12 to more than 750 hp and over 900 lb-ft of torque is just the start, however. For drivers who have access to 93 or 94 octane pump gas, Speedriven bumps the 600-series cars to 800 hp and over 940 lb-ft of tide-altering torque.



The Speedriven package fitted to the W215-chassis Mercedes CL600 shown here features a set of billet-wheel turbochargers, a powder-coated set of Speedriven’s top-mounted water-to-air intercoolers, “scorpion” air intakes, K&N cone filters, and Speedriven’s ECU software to manage the extra air density and extra boost. The car also features Speedriven’s transmission controller upgrades, allowing the car to handle the extra torque and giving the 600 series Mercedes cars a more “true” manual mode to hold gears more aggressively while delivering quicker, firmer shifts in “sport” mode (comfort mode retains the 600′s usual silkiness).

This Speedriven tuning package includes:

- SPEEDRIVEN BILLET-WHEEL TURBO UPGRADES
- SPEEDRIVEN TOP-MOUNTED INTERCOOLERS
- SPEEDRIVEN SCORPION AIR INTAKES
- SPEEDRIVEN ECU/TCU UPGRADES
- SPEEDRIVEN HEAT EXCHANGER
- JOHNSON CM30 PUMP
- AND MORE ...

 

The high horsepower packages dont retain the factory airbox covers ?

 

The larger Speedriven intercoolers occupy the space that is normally occupied by the factory airbox. You can have big hp and adequate cooling or you can have a factory airbox - not both.

Given the limitations of the factory intercoolers, though (which aren't enough for even the factory turbos, IMO) I think the wrinkle-black finish blends in well enough with its under-hood surroundings. What do you think?

 

I've seen a SL65 with the exact same air intake setup here, it's not bad but I would of preferred something that looks more oem.

 

Jo,

It that your daily sleeper?

 

We can do the intakes as a stand-alone item, but it doesn't really make sense. The way I usually explain the steps to building power on these cars is:

Step 1 is an ECU flash, which "derestricts" the car.

Step 2 is the TCU flash, which doesn't make sense on a 100% factory car (because the TCU flash addresses torque limits and high speed/high rpm conditions which you'll never reach with a factory tune)

Step 3 is upgrading the factory IC pumps and heat exchanger, because the factory system can barely keep up with the cars stock. Now you're pushing the factory turbos and you need to keep temp. under control.

Step 4 is the Intercooler PKG (which includes the scorpion intakes) because now that things are cool enough, the choke-point becomes the intakes. More air coming in means more to compress, temps down means we can build more boost, which needs to be cooled by the top-mounts, etc.

Step 5 is the upgraded turbos, since (after step 4) the limitation is the factory turbos. Once you upgrade these, you're making big power, and the only choke-point left is ...

Step 6 ... the factory downpipes and exhaust, which only frees up about 20-30 whp, depending on the model.

Doing things in a different order just seems foolish. Upgrading the turbos without the coolers will just heat soak everything right away, you know? Doing the TCU without the ECU means you'll never feel a difference at all. Etc., etc.

As for OEM-look - we can do something like that on a case by case basis, but from our point of view there was no business case for it. It would add thousands to the cost of the kit, it would be unique to each model (W215 vs. W221, for example), and it would likely not add to the performance of the car.

Like I said, though: if a client wants an ultra-slick 1-off carbon panel, we have the tools and people to make it happen!

 

I wish! I still have the Routan I asked you to try to bail me out of a year ago.

 

How many rwhp does the modified SL65 do with 93 octane ?

 

I have a few dyno pulls showing 680+ to the wheels, on the early versions of these turbos. I'm confident enough to claim 700 with the latest updates.

 

Heck, we can get more than 700 whp on race gas from an SL600, let alone a 65AMG!
