More grunt for your Jeep
With Whipple’s third-generation blower bolted in place, RGMotorsport’s Jeep Grand Cherokee SRT8 6.4 Hemi upgrade produces a Trackhawk-whipping 546kW and 928Nm – enough to propel the burly SUV to 100 km/h in an estimated 3.6 seconds and to a top speed of 290km/h.
That’s the news from the country’s foremost proponent of aftermarket supercharging and with dozens of blowers fitted to American-based V8s (including 20 Mustangs) they have all the experience needed to claim pole position. With the latest Generation 3 Whipple unit nestling in the V of the Grand’s eight cylinders, power is claimed to be delivered in a more refined and effortless manner than before.
There’s more outright grunt too; changing to the latest forced induction technology upped power from the 520kW previously available, with torque climbing by almost 60 units.
The impressive headline numbers are also thanks to a full RGM-Techniflow dual 76mm stainless steel exhaust system along with ceramic-coated headers to blast out the hot gases with minimal delay. An ECU software download comes straight from the Whipple factory and is finetuned by RGM’s team to suit SA climate, fuel and conditions.
Each car is performance optimised on the company’s fourwheel drive dynamometer and, finally, road tested.
RGM’s full-house upgrade costs R268 700 including all management hardware and software, as well as a 76mm stainless steel Techniflow exhaust system with ceramic-coated tubular headers.
The upgrades include a sixmonth/20 000km warranty. – Own Correspondent when they are a puppy or kitten.
