9-Second Stock Challenger Hellcat

November 20th, 2018

Greetings drag racing fans and welcome to Atco Dragway in scenic New Jersey, USA. On tap today is a stock Dodge Challenger SRT Hellcat that is capable of blowing through the quarter-mile in just over 9-seconds (9.17-seconds @ 150.58 MPH).

Knowing that the Hellcat package includes a supercharged (707HP) 6.2-liter HEMI engine, you might be wondering how fast Dodge says this cat can claw through the 1320. Strangely enough, Chrysler only has its flagship coupe getting through the quarter-mile in 10.8-seconds. So, where did this racer shave nearly 2-seconds?

No hard parts have been changed and neither the engine nor the supercharger have been opened for mods; although porting and polishing the cylinder heads and blower would be a definite improvement. No intake or exhaust manifold enhancements – it’s all factory. The rear tires are a bit fatter than factory but what gives this car the edge to call itself the World’s Fastest Stock Hellcat? It is all in the tuning.

Barth Tuning in Freeport, Illinois is the difference in this equation. Check it out.
