When it comes to enhancing the performance of a vehicle, especially a powerhouse like the Grand Cherokee SRT, enthusiasts often seek the best upgrades available. One such upgrade that has gained considerable attention is the Hennessey HPE700 kit, which promises to elevate your driving experience to new heights. In this article, I will share my personal experience with the $1,200 Hennessey HPE700 kit and how it transformed my Grand Cherokee SRT.
The Initial Impressions
Before the installation of the HPE700 kit, my Grand Cherokee SRT was already a formidable vehicle, boasting a powerful V8 engine. However, I was eager to push the limits further. The sleek design and aggressive stance of the SRT were already captivating, but I wanted to enhance its performance capabilities.
Upon receiving the Hennessey HPE700 kit, I was impressed by the quality of the components. The kit includes a high-flow air intake system, upgraded fuel injectors, a new throttle body, and a reprogrammed ECU, all designed to optimize performance. The installation process was straightforward, and I decided to tackle it myself, which added to the excitement.
Installation Process
The installation of the HPE700 kit took me a weekend to complete. I gathered all the necessary tools and set up my workspace. The first step was to remove the factory air intake system, which was surprisingly simple. With the right tools, I was able to detach it without any issues.
Next, I installed the high-flow air intake system from Hennessey. This component was designed to improve airflow to the engine, and I could already envision the performance gains. After securing the new intake, I moved on to the throttle body and fuel injectors. Each component fit perfectly, and the instructions provided by Hennessey were clear and easy to follow.
Finally, I connected the ECU and uploaded the new performance tune. This was the moment of truth. Would all my efforts pay off? I took a deep breath and turned the key in the ignition. The roar of the engine was music to my ears.
Performance Enhancements
After the installation, I took my Grand Cherokee SRT for a test drive, and the difference was immediately noticeable. The throttle response was sharper, and the acceleration was exhilarating. The HPE700 kit increased the horsepower to an impressive 707 hp, which made a significant difference in everyday driving and during spirited runs.
Here are some key performance enhancements I experienced:
- Increased Horsepower: The jump to 707 hp was a game-changer.
- Improved Throttle Response: The engine felt more alive and responsive.
- Enhanced Sound: The exhaust note was more aggressive, adding to the driving experience.

Daily Driving Experience
While the performance gains were impressive, I was also curious about how the HPE700 kit would affect daily driving. I use my Grand Cherokee SRT for commuting, errands, and family outings, so comfort and drivability were essential factors to consider.
To my delight, the vehicle remained comfortable and practical. The ride quality did not suffer, and the added power only enhanced the driving experience. Merging onto highways and overtaking slower vehicles became effortless, and I found myself enjoying the drive more than ever.
Fuel Economy Considerations
One concern I had before the installation was the potential impact on fuel economy. With increased power, many assume that fuel consumption would rise significantly. However, I was pleasantly surprised to find that my fuel economy remained relatively consistent.
Here are some observations regarding fuel economy post-installation:
- City Driving: Minimal difference in fuel consumption.
