RENNtech sets a new SLR world record…Again!

Living life a quarter-mile at a time.

On April 22nd, 2011, RENNtech Inc. set a world record for the fastest Mercedes-Benz SLR McLaren at Palm Beach International Raceway with a 10.439-second at 133.04 mph quarter-mile time.

For those that aren’t familiar with the Mercedes-Benz SLR McLaren, it is a super car that was joint-developed by Mercedes-Benz and McLaren, and was inspired by the 1955 Mercedes-Benz 300 SLR. Under the hood is a hand-built 5.4-liter supercharged V-8 engine that produced a maximum 13 PSI of boost, 617 horsepower at 6,500 RPM, and 580 lb-ft. from 3,250 – 5,000 RPM.

RENNtech has modified the SLR to crank out 770 horsepower with a host of in-house products. To achieve such a fast quarter-mile time engineers installed a RENNtech modified supercharger pulley, retuned the ECU, a new RENNtech transmission cooler upgrade, RENNtech sport exhaust, new heat exchangers, a larger intercooler pump, and Hoosier drag radial tires.

Packed with 770 ponies, RENNtech headed out to the track to break their own world record. The first run yielded a 10.29-second at 134 mph quarter-mile time, setting a new world record. The second run resulted in another 10.29-second at 134 mph quarter-mile time, supporting the fact that it is the world’s fastest SLR McLaren.
