Ever since 2011, when Chrysler introduced encrypted ECUs into their vehicles, enthusiasts looking to eek a few more ponies out of cars like the Challenger, Charger, Chrysler 300 and RAM pickups have had a much more difficult time going about it – especially when a new model debuts.
The Challenger and Charger Hellcat have been available to the public for nearly a year now, but we’re just starting to see some aftermarket tuning solutions that don’t require swapping out the entire engine management system of the car, running alternate fuel or other tricks that either require an extensive (and often times, unreliable) reworking of the car’s on-board systems or a metric ton of cash to accomplish very minimal results.
These folks managed to knock a few tenths off their quarter mile time in an almost entirely stock Charger Hellcat with an unnamed female pilot at the helm using just a few subtle tweaks.
As far as mods go, there’s a lower overdrive pulley from ATI to up the boost by about 2.5 pounds, MS109 fuel and some ongoing ECU test and tuning with the folks at Diablosport – and aside from the non-stock rubber out back, that’s essentially the sum total here. The result though? In showroom stock configuration the car put 643 horsepower to the wheels, now it’s up to 730 ponies on 93 octane fuel, and over 750 on the MS109 fuel.
It all results in a fastest time of 10.67 at 130.85 mph – a seriously fast time for the mostly stock vehicle, and one that’s claimed to have made this the fastest Hellcat Charger in the world. So far.
