Just finished...World's Only SLK65 AMG V12 BiTurbo

We often get many requests for special projects, modifications, and high-performance work. This project, which was completed after nearly two years of engineering and work was one of the most difficult creations I've ever endured. Customer request...install the largest, most powerful engine and transmission from Mercedes-Benz... A V12 Twin-Turbo from a CL65 AMG into a little SLK...and make it look, drive, and function like it came from the factory. Well, here it is....the only SLK65 AMG in the world built by us. 750hp, 900 lb-ft of torque.

Wow! Very cool. I would have left the V12 emblems off and went hunting.

What an audacious concept. It certainly looks OEM to me, very clean engine bay. What kind of rear tyres does this thing have? Surely traction must be an issue with so much power and so little weight over the rears? Alo, videos are a must please!

It has Michelin Pilot SuperSports in 19" staggered setup. Yes, the car roasts tires from a hard launch. Once you get used to the throttle though, you can launch this thing like a rocket ship. Keep in mind, it still has the 3.06 rear axle ratio from the SLK55! 40mph-120mph thrust is an out of world experience!

Does this car ever go straight? I'd think it would be sideways all the time. At least my old 55 did!

I wonder how long it will take for someone to post a pic in the poser section. SLK65 Ha.

Would love to see this beast run some 1/4s.

Damn I want a reinforced 3.06 pumpkin! Surprised slk stockers lasted even at oem power levels? I know of 1 cl65 that ran 2.82 but from Maybach 67 S supposedly heavily reinforced, as norm sl55 2.82 was tried on 65 & blew its bags shortly after install. Hard to believe the delicate slk 3.06 is not only holding oem power but moded to 750/900 is extremely hard to believe..

I'm imagining it might survive, as if the 3.06 is still stock it prolly doesnt have LSD & just does mile long peg leg burnouts? (not being negative, just trying to understand how stock 3.06 on slk can handle any of this extra power, the torque output alone is nearly tripled, what trans is it using? If stock? I'm dumbfounded)
More info please sounds/looks like you did some quality work..

We reinforced the differential early on. Yes, it DOES have LSD as you can see by the burnout on our Facebook page. Two nice black linear stripes follow the car. A modded/tuned V12 ME 2.7.1 typically makes 750hp easy. Most of the tuners offer this...ie RennTech, Kleemann, etc.

This car has the V12 CL65 AMG transmission and matching EGS52 transmission control unit as well. There are no cats either.

There is an early (with the old wheels) video on our Facebook page (just search for Motorwerks) and it's on there. There'll be more. Stay tuned...

How did you reinforce the differential?

Are your power numbers estimated based on other cars performance?

Did you tune the EGS52?

Would love to see some 1/4 mile runs

Thanks

Wow, amazing that you pulled off something like that!

If you had to pick between this and an SLS roadster, which would you have?
