Meet the 1st 10-Second Manual Transmission Hellcat Challenger

by Patrick Rall on


We have seen Dodge Challenger SRT Hellcats running in the 9s and 10s, but all of those cars were fitted with the quick-shifting 8-speed automatic transmission. This past weekend, the first 10-second run by a Hellcat Challenger with a manual transmission was recorded by Jon Sipple, who broke way into the 10s with a very short modification list.

Some folks from the Ford camp have long insisted that the Hellcat Challenger is nowhere near as quick with the manual transmission. Basically, Mustang fans insist that the Hellcat is much quicker than the previous Shelby GT500 solely because the Mustang only had a manual transmission.

Jon Sipple and his manually-shifted Challenger SRT Hellcat have proven that, with some sticky tires, the supercharged Dodge muscle cars are every bit as capable of running low 11s and high 10s.

Before getting into his 10 second runs, some quick background on Jon Sipple and his claim as the quickest manual Hellcat. According to the gurus at, Jon’s best time last December of 11.18 at 125 miles per hour made him the quickest manual Hellcat driver in the country. At that time, Jon’s only modifications were a stronger driveshaft, a cold air intake, and drag radial tires. Since then, there have been no other reported times quicker than that 11.18 – until Jon his Hellcat Challenger hit the track with a few new modifications.


Since his last trip to the track in December, Sipple added a Diablosport tune, a light cooling charge of nitrous, and a set of big, fat drag radial tires. His goal was to break into the 10s – but he did far more than just break in.

On his first run out with the new modifications, he was able to stop the clock with a time of 11.000 at 130.83 miles per hour, the blink of an eye from the tens, with a 60 foot time of 1.937. On the next run, Sipple got off of the line a bit better and ran an incredible 10.86.  Finally, on his last run of the day, Sipple laid down another 10-second run with a 10.89.

Sipple drove his Hellcat Challenger two hours to the track, raced all night and drove two hours home – getting 22mpg on the trip.

Jon Sipple plans to spend some time on the dyno with his Hellcat Challenger next month and after that, he might be much further into the 10s. We will keep you posted on that, but in the meantime, check out the videos of Sipple’s record-setting runs.
