Our RENNtech modified SLR McLaren yet again breaks its own recently set World Record time of 10.43 @ 133 mph with an incredible 10.29 @ 134 mph pass. Immediately after besting its own record, the SLR backed up its newly set time with yet another 10.29 @ 134 pass, proving this SLR is consistently a record breaker.

The SLR sports a hand-built 5.4 L (331.9 cu in), supercharged, all-aluminium, SOHC V8 engine with three valves per cylinder. When stock, the Lysholm-type twin-screw supercharger produces approximately 0.9 bar (13 psi) of boost and generates 617 horsepower (460 kW; 626 PS) @6500 rpm.

In addition, this vehicle is equipped with our latest proprietary transmission cooler upgrade, RENNtech sport exhaust, modified heat exchangers ,a higher volume intercooler pump and Hoosier Drag Radials.
