Hennessey has just released a new package for the Ford Mustang Shelby GT350, which was last put on the dyno previously. The video showed that the 526hp/582 Nm 5.2 litre Voodoo flat-plane crankshaft V8 pushed out figures of 482 hp and 551 Nm at the rear wheels, that’s roughly around 530 hp and 607 Nm at the crank – more power than what was expected.

Now, the Texas tuning company has come up with a new custom modification pack called the HPE575, which extracts more power from the naturally-aspirated 5.2 litre V8 mill. To be exact, with said modification pack, the Shelby GT350 will be able to churn out 575 hp at 7,700 rpm and a massive 692 Nm at 4,600 rpm. There’s a more potent HPE800 pack with 808 bhp – but that involves a supercharger system.

All it takes to achieve that 575 hp figure is a high-flow catalytic converter, a stainless steel mid-pipe exhaust, 1.75-inch stainless steel long-tube headers and an engine management upgrade. Said items are all part of the HPE575 kit. That’s not all, Hennessey also provides chassis dyno calibration, Pennzoil Ultra Platinum synthetic oil and filter change and a full tank of petrol, at that.

Other items that are thrown in include a serial numbered plaque, unique badges and floor mats too. In addition to that, once the kit has been installed, Hennessey will carry out road tests in the modified Shelby for up to 160 km, while a three-year/57,000 km warranty comes as standard.

As for the prices, the HPE575 kit can be had for less through mail order, which is packaged at USD$4,995 (RM21,850). To have it installed in-house by Hennessey, owners will need to fork out USD$6,950 (RM30,400), instead. A total of just 100 kits will be produced for the 2016 MY Mustang Shelby GT350, while all cars will come with individual Hennessey serial numbers, from 1 to 100.
