RENNTECH SL65 Black Series churns out 1000 LB-Ft of torque!

Tuesday, July 20th, 2010

RENNTECH and Domani Motors are proud to present this gorgeous SL65 Black Series equipped with RENNTECHs Performance Package 1.




RENNTECH also outfitted the vehicle with a Transmission upgrade and 100% Locking Rear Differential. These modifications are essential when attempting to transfer ridiculous amounts of power. It’s amazing how the upgraded differential completely transforms the cars driving dynamics. The driver can now feel in command of the vehicle when pushing the Bi-turbo V12 to its limits. CLICK HERE to check out all of the RENNTECH SL65 Black Series performance products that are available.





In the end, this project was truly a great experience with the team over at Domani Motors. Now enough chit chat lets get to the good stuff, check out the pics and video…

RENNTECH FOR SLK350 V6

Wednesday, February 4th, 2009




RENNTECH’s new $3995 performance PKG1 for the 05-08 SLK 350 boosts the output of the 268 hp V6 to over 300 hp. That’s 40 horsepower for under $4000!

This level of performance and torque comes from new RENNTECH headers and a RENNTECH ECU upgrade, which also raises the car’s top speed from the factory-limited 155 mph to over 170 mph. As the copy above states: this package will change the way you look at Mercedes’ 350 series cars.

Currently available for 05-08 SLK350 and GLK350

750 HP SLR – ON THE DYNO

Wednesday, January 14th, 2009




The video above shows a fantastic Switzer-prepared SLR McLaren coupe putting out 600 hp at the wheels – that’s almost 750 hp at the crank!

This SLR makes use of RENNTECH’s SLR PKG1 performance upgrades and the latest version of the RENNTECH’s SLR McLaren software. Each SLR engine is assembled by hand at AMG, of course, and there are sometimes slight variances, but this is still a STRONG build – Switzer (our primary Ohio dealer) did a fantastic job getting the most out of this McLaren on pump gas (RENNTECH advertises 722 hp, or just under 580 hp at the wheels).
