This is seriously close.
The Ford Mustang Shelby GT500 is undeniably brilliant on the track and Ford wants owners to take advantage of its capabilities in the corners, but as you can imagine, a car with a 5.2-liter supercharged V8 producing 760 horsepower is a prime candidate for straight-line racing too. That has made it pretty popular with aftermarket tuners, and two owners have taken their GT500s to new heights with output on each car now at over 1,000 horsepower. However, the owner of each car has gone about things in their own way, and the Iconic Silver model starts the day off with a previous personal best of 9.7 seconds while the Grabber Lime model's owner had only achieved a 9.9. This should be close.
As you can see from the video, the race was remarkably close; so what's the difference between the two cars, and why did the supposedly slower car win? Well, the green car, known as "The Hulk", features an upgraded supercharger pulley, bigger camshafts, new injector fuel rails, a larger throttle body, a revised intake system, and runs on E85. In addition, the rear seats have been stripped for weight reduction. The silver car, on the other hand, has similar modifications but from different companies and runs on One Ethanol Race fuel that is rated at over 85 percent ethanol for an octane figure of over 117. However, this car is a full-weight car. Both 'Stangs are tuned by the same company.
As you may have noticed, the silver car that managed to best its personal record with a time of 9.5 seconds on the day struggled to make a clean start. Although both drivers had excellent reaction times, the silver bogged off the line despite previously executing a flawless launch. The problem comes down to the tuning of the dual-clutch transmission, and the owner has no idea why it's so inconsistent. Despite running the same tune over and over, the results on the track seem to be near impossible to replicate reliably. We're sure that 1320 Junkie (Jason Teixeira) will be able to get to the bottom of it eventually, and hopefully, a rematch can happen so that the Goliath in this story can slay its David.
