The Ford Mustang Boss 302 is a car that needs no presentation. Every Mustang fan has been impressed by it ever since Ford announced it back in March and most consider the engine’s standard 440 horsepower and 380 lb/ft of torque to be just perfect for a muscle car.

That being said, Hennessey has found a solution to improve it even further, despite the fact that the Mustang Boss 302 is about as awesome as any Mustang can get nowadays. In any case, the whole package revolves around the performance improvements on the car. At the heart of it all is the installation of a new supercharger system that boosts the output of the muscle car by over 600 ponies, which is to say that the rich just gets richer.

On top of that, the package also includes a few visual additions to ensure that whenever people walk by your Mustang Boss 302, they know without a hint of doubt that they’re looking at a Hennessey-tuned muscle car.

John Hennessey has run the whole gamut of American muscle cars under his company, so it’s no secret that the Ford Mustang Boss 302 has been taken in for some upgrades too. On the outside, there doesn’t appear to be too much of a change from the standard set-up with the exception of the carbon fiber door sill covers, a number of Hennessey badging and plaques, and premium floor mats. For an added option, buyers can also get a carbon fiber racing splitter and a set of Hennessey monoblock wheels.

Other than those minimal additions, the overall make up of the car remains largely the same. But make no mistake; whatever it lacks in aesthetic upgrades, it more than makes up for in performance tweaking.

The Ford Mustang Boss 302 carries a 5.0-liter V8 engine that produces 440 horsepower and 380 lb/ft of torque, but that’s before Hennessey worked their magic. Thanks to an Eaton TVS2300 supercharger that has been configured to pump out 10psi of boost, the new Mustang Boss 302 HPE650 performance package sends power levels through the roof, hitting a staggering peak of 650 horsepower.

On top of the new supercharger, the Hennessey HPE650 program also carries a new strut tower brace, a throttle boy upgrade, an air induction system, fuel injectors, and a custom engine management calibration, among other things.


According to Hennessey, the HPE650 Boss 302 upgrade package will cost $15,995. On top of the package, this price also covers professional installation, dyno tuning, serialized dash and engine plaques, and a 3 year / 36,000 mile warranty.

The added options that come with the package also carry individual price tags with the carbon fiber front racing splitter priced at $2,500, the Hennessey monoblock wheels going for $5,500, and the mounting kit for non-Laguna Seca models costing $750.

The choice between a Ford Mustang Boss 302 and a Chevrolet Camaro is made all the more difficult if you factor in a Hennessey tuning package. Granted, the American tuning firm offers programs for each model that improve the output to 650 horsepower, but while we’re pretty high on the Camaro against the Mustang in standard format, the allure of a Hennessey-tuned Mustang Boss 302 just might be too sweet of an apple to resist.

In the end though, these two models are pretty much evenly matched so while we say one thing, other people might say another. Either way, nobody’s wrong; one car’s as good as the other.

This is one of the great cars coming from Hennessey. The combination of its colors are perfect.. It’s like a customized car.. Its body design are very good in every angle specially the yellow one.

I was wondering if Hennessey is not satisfy with the figure performance of this car? Well, aside from the modification in the exterior of the car which really makes the Boss 3302 more sporty. Its a good thing that they offer an engine upgrade as well.

I have to admit that I already fell in love with this car on my first glance of its first released! I’m impressed with its aggressive styling and high speed performance.

We all know that Hennesey is one great tuning company and what they’ve done with this Mustang is really great. Well, the engine upgrade is quite impressive too but in exchange, the price is doubled. Do you think it is reasonable?
