Volker Mornhinweg, the AMG boss, declared last week that the horsepower war is over and they won’t try to reach extreme performances with the cars they modify. Hartmut Feyhl, the boss from Renntech, still likes powerful cars which can reach incredible speeds and he announced that his company will reveal Renntech 777 Mercedes SLR McLaren, a car developed to celebrate the company’s 20th anniversary, which has 777 HP. The car tuner says this is a completely new street legal track car and it will have a new body kit with improved aerodynamics, a big rear wing, new splitters and new side skirts. The car will be powered with a modified 5.5L supercharged Kompressor V8 engine and it will feature a new suspension, driveline and a special slip differential made by Renntech.

When Mercedes decided that it’s time to boost the engine power for this lovely SLR supercar they created the limited edition SLR722. A lot of people thought that 722 comes from the power developed by the 5.5L V8 engine of this car while others thought that there will be built only 722 cars like this one. But they were all wrong. In fact the car’s name comes from the Mille Miglia from 1955 where Stirling Moss and Denis Jenkinson won with a Mercedes-Benz 300SLR in front of race favorties like Ferrari and Porsche. The car had the racing number 722 which was the exact hour of race start 7:22 am.
Last year, the car tuning company Renntech ended this confusion and boosted this car’s power from the initial 650 HP to 722 HP. The PKG1 kit included new intercoolers and modified engine cooling unit that will add this slight boost of power. [click to continue…]
As a stock car, the Mercedes CLK63 AMG Black Series is one of the most extreme cars ever built. With a body kit that looks like the one used at DTM cars, an interior with carbon fiber elements and a powerful V8 engine that develops 507 HP and 630 Nm, this car seems perfect and you can’t make it better.
Of course, it seems that nothing is extreme for the guys from Renntech and the car tuning company from Florida has added 43 HP to the car’s V8 engine by modifying it’s engine cooling system and installing a new high performance exhaust system. With this extra power this car will accelerate from 0 to 100 km/h in less than 4 seconds and it will reach a top speed of over 300 km/h. [click to continue…]
Mercedes S65 and CL65 is definitely a dream car for most of us and we’d be delighted to have one, but… there are some people that don’t believe this car is great enough and they’re trying to improve it, and fine tune it’s performances. The guys from RENNTech thought that 500 HP is not enough for this Mercedes and they wanted to improve the car’s performances. They’ve modified the V12 engine and after a couple of days the engine could develop 695 HP and a maximum torque of 895 Nm. This performance tuning kit is called “stage 3″ and uses improved engine cooling unit that would make your car’s engine “chill out” after a short race. [click to continue…]
