RENNTech SLR Shows Extreme Performance From Minimal Mods

Some people just have no respect for the Mercedes engineers who spend hundreds, if not thousands, of hours testing and tuning the carmaker’s products for the best performance. And that’s actually a good thing, because if there were no tuners like RENNtech who seek to obtain the ultimate performance from cars they lay their hands on, we wouldn’t be seeing this video.

Billed as the world’s fastest Mercedes-powered Mercedes, this video shows a RENNtech-tuned Mercedes SLR McLaren doing a 10.31 in the quarter mile. With a trap speed of 136 mph, it’s pretty quick, considering that the mods done to it consisted only of bolt-ons. Combining a smaller supercharger pulley, upgraded intercoolers, revised ECU and a sports exhaust resulted in an output of 770 horsepower. As you can see, the tuner left well enough alone but even with these relatively minor mods, the resulting performance was enough to turn in a pretty quick time.

 

RENNtech CL65 Lays Claim To Fastest Mercedes Quarter-Miler

Publicizing performance numbers of your modified cars is part of the tuning game, as it entices would-be customers towards particular products or vehicles that capture the public’s attention. True to form, RENNtech has trumpeted its quarter-mile time of 10.27 seconds as an achievement to which it is claiming the title of being the world’s fastest Mercedes.

This quarter-mile time, together with a trap speed of 137.46 mph was hit on April 1 of this year at the Palm Beach International Raceway. The CL65’s previous time of 10.51 seconds had been bested by a nitrous-powered C63 and so RENNtech set about to rectify this situation by having its engineers find the extra power necessary to shave more time off the CL65’s already fast 10.5. Mods include a race only tune, upgraded transmission internals and a prototype torque converter. The previous modifications like upgraded ECU/TCU, carbon airbox, limited slip differential, high flow exhaust, drag radials, modified heat exchanger and intercooler pump were retained. Additional lightweight components were used to make the power-to-weight ratio more favorable. According to the tuner, “RENNtech looks to continue shattering its own records and will be further modifying the CL in search even more performance in pursuit of the first 9 second Mercedes Benz.”

RENNtech Brings CLK 63 Black Series Carbon Upgrades to Market

RENNtech, one of the premiere Mercedes-Benz tuners, had been providing some CLK 63 Black Series one-off carbon fiber aerodynamic add-ons to a select group of people such as Indy Racing driver Tony Kanaan. Now, the company is making these upgrades available to the general public, mainly due to interest and demand from consumers.

The carbon fiber aero add-ons available include the following: a full-carbon fiber front splitter ($2,450) for that aggressive styling up front, increased brake cooling and improved handling via additional downforce; front air ducts ($1,250) that increase air flow to the brakes for better cooling and reduced pad wear and brake fade; a redesigned full-carbon air box ($2,795) with a new carbon vacuum chamber box, optimizes path of airflow and increases volume as well, up to 10hp added; rear diffuser ($3,250) that increases downforce and reduces drag, plus it also redirects air to help the rear differential oil cooler; a carbon DTM adjustable rear wing ($3,350) for improved styling plus increased downforce and stability; and front && rear adjustable camber bushings ($1,250 for front, $954 for rear) for adjustable handling to accommodate a variety of tracks as well as driving styles. The individual parts are available in gloss or matte finish.

As you can see from the prices of those aero upgrade components, there was really a reason why they remained exclusive options until now. Still, one can’t argue with the effort and engineering it took to come up with these carbon fiber upgrades.

The Renntech C74 Performance Package unleashed

Germany’s not the only country with its pool of talented Mercedes-Benz tuners. One of the best MB tuners in America, Renntech, now offers their latest take on the C63 AMG.

They call it the Renntech C74. The modification package includes upgrading the stock 6.2-liter V8 to churn out 605hp and 555lb-ft. This means the quarter mile run will take merely 11.4 seconds, while top speed is pegged at around 204mph. Lots of credits for the power improvement go out to Renntech’s carbon fiber airbox and high performance filter, a custom air inlet panel, 82mm throttle bodies, more aggressive camshafts, ported and polished cylinder heads, ECU with updated software, stainless steel headers,  performance exhaust system, a 100% locking limited slip differential, fully customizable sports suspension system, Renntech’s Stage 3 Performance Braking Kit, and carbon fiber stabilizer bars for both front and rear.

In case you’re scratching your temple on how Renntech came up with the 74 badging, let’s just say that it’s purely based on the width of the rear wheel track, which measures 74 inches. This allowed the rear drive axle to be able to accommodate up to 11-inches of rims and 315 mm tires.

Of course, it wouldn’t be complete without its host of carbon fiber exterior enhancements, not only to make it look meaner but to make it behave a lot better on the road. These consist of carbon fiber rear decklid spoiler, front splitter, rear diffuser with integrated exhaust tips, 3-piece forged aluminum wheels and Nitto INVO performance rubbers.

Price of the performance package? $11,900. Not bad eh?

The Domani Motors-Renntech SL65 AMG Black Series

Ready for a little bit of madness? Some time back, the guys down at Domani Motors were able to get their hands on an SL65 AMG Black Series, and put it in their showroom. However, they weren’t really intent on keeping the car in ‘stock’ form. They felt that the car was capable of even more awesomeness, and so that’s what they did. They perked up the car and made it even more other-worldly than it already is. They did this with the help of their pals down at Renntech, whose Performance Package 1 was just what the doctor ordered to make their dreams come true.

For those of you who are boggled out of your minds, it’s sort of PCP for the Silver Arrows. The teams worked together to remap the ECU, install a more open exhaust system plus a few other neat tricks to manage the impossible. The end result is around 805 horsepower and 1,000 pound per feet of torque. And what’s even more impressive is their brainchild is completely streetable, albeit with a few reminders to whoever is going to drive it. There’ll be cops on the loose, mind you.

If you do end up driving one, might we suggest that you take note of the 100-percent locking rear differential that the guys put into place. It takes all the power the engine can muster and throws it without any consideration to the rear wheels. Remember, this sort of hardware is almost similar to a spool, which is ILLEGAL in most states in the US, by the way. It’s the sort that race cars come equipped with to tear down corners on a race track. The car also comes with an upgraded tranny to comfortably handle the immense power of the engine. Excessive? Not quite. Fun? Undeniably.
