Video: Jeep Grand Cherokee SRT8 twin turbo runs 9.46sec

Check out this for the ultimate soccer mum’s car. It’s a 2007 Jeep Grand Cherokee SRT8 twin turbo capable of nine-second quarter mile passes.

The Jeep Grand Cherokee SRT8 is already a fairly stout machine, coming equipped with a 6.1 HEMI V8 producing 317kW of power and 576Nm of torque. It’s capable of running the quarter in 13.2 seconds. Someone in the US decided those standard figures were a bit tame. Fair enough.

This example features a Gen III 426 Hemi twin-turbo conversion which takes power levels up to a truly colossal 852kW at the wheels; that’s 1142hp to all you old-fashioned types. Not a bad effort indeed.

The owner has managed a quarter mile of 9.56 seconds at 233km/h (144.55mph) with pretty ordinary tyres. With some more decent treads on all four wheels, the Jeep Grand Cherokee SRT8 twin turbo conversion smashes the quarter mile in just 9.46 seconds at 234km/h (145.35mph).

According to the owner, it is a daily driver. He even drove the Jeep Grand Cherokee SRT8 twin turbo 11 hours to get to an event to run some times on one occasion. On arrival he simply swaps the tyres.
