After landing on long-deprived African soil in late 2015, Ford’s Mustang was always going to become a tuner’s delight, and now renowned local tuner RGMotorsport is entering the pony wars with its mighty supercharged ‘stang.
The logical starting point in this case is the normally aspirated 5-litre V8 GT version, rated at 306kW and 530Nm in standard form. With a specific output of just 61kW per litre, this engine was just begging to be tuned, and RG has not fooled around in that regard, with the end result being in the region of 550kW, for a wholesome 110kW per litre, and 895Nm. RG Motorsport also promises to verify your engine’s output on its dyno before leaving the company’s Randburg-based headquarters.
The key ingredient here is a Whipple W175ax 2.9L supercharger, driven by a six-rib belt system with adjustable idler set-up. Imported from the US and configured specifically for this particular engine, the blower is positioned neatly within the engine’s ‘V’. According to RG, the unit’s twin-screw design allows for instant response and loads of low-end torque.
Also fitted is a front-to-back 76mm Techniflow performance exhaust system, which includes branches and a dual sound level function for that appropriately sinister, rip-roaring soundtrack.
Total cost of the upgrade is R199 900 - add that to the Mustang GT fastback's R852 900 purchase price and you’re looking at R1 052 800 for this beastly creation. Compare that to the R1 152 976 that you'll pay for a new BMW M4 Coupe, with just 317kW and 550Nm, and there is big bang for the buck factor here, albeit without the German car's ultimate sophistication or after-sales backup. On that note, RG's purchase price includes a six-month/20 000km warranty on any defects that might be associated with the conversion and clients can also opt for a two-year/75 000km warranty extension, at R13 600, provided the donor car meets certain age and mileage criteria.
