There can’t be that many people out there who would say that power is one of the things that the Dodge Viper ACR – one of the fastest and most track-focused cars in the world - needs to try to improve on. Because, for most people, 645 horses and 813Nm of torque is more than enough. That naturally-aspirated 8.4-litre V10 sure is producing the goods, and with exclusive equipment including carbon ceramic matrix brembo brakes, a unique track suspension and special tyres, there isn’t much else the model can do to be better – but not according to GeigerCars. It has found a way…

The German tuner has worked its magic on the Viper ACR and gotten 120 horses more out of it. Nope – it didn’t just shove a turbo under that long bonnet and said ‘job done’ it went the old fashioned route of you know, getting your hands dirty. To get to the new 765 horsepower figure, they added larger 2.215in diameter intake valves, a high-lift camshaft, uprated hydraulic lifters, pushrods, and double valve springs. Then, they added catalytic converters, a stainless steel exhaust system and tweaked the ECU some more and made the wild car even wilder. How wild? Try 920Nm of torque wild…

It isn’t just the oily bits that GeigerCars – the Munich-based US car specialist - busied themselves with; they created an ‘Extreme Aero Package’ for the Dodge, which, yep already had a rather aggressive aero package on it! The new bits include a front splitter, twin dive flaps on the front apron, a new rear diffuser and a set of 19in lightweight forged alloy wheels.

Fancy upgrading your ACR to this? Then all you need is $46,000 (Dh170,000). Oh, and a Viper ACR of course…
