Hennessey Released New Shelby GT350R Upgrade – One hp for $44.5

Hennessey released a simple upgrade for the most track-ready Mustang ever – the Shelby GT350R. Called the Mail Order Update, the basic kit consists of a simple cold air intake and an ECU remap. And yes, anyone can install it. Ok, not anyone, but not-so-experienced mechanics can. This is the beauty of it all. Hennessey released pictures of the car rigged at the Dyno measuring its power output. In fact, installing the “Mail Order Update” will release more hps and more lb-ft. After all, Voodoo V8 churned out 490hp and 411 lb-ft of torque to the wheels. Stock, it’d do 460 hp and 385 lb-ft of twist.

Now, Hennessey offers a whole set of different upgrades for the GT350R. Superchargers, new engine internals, even more extreme ECU remaps and all other stuff could potentially improve the engine output to more than 700hp. Hell, one can even order an HPE800 upgrade. And we all know what the number after the HPE means.

However, one does not have to go all the way to HPE800 to get its Shelby more punch. Hennessey crafted the HPE575 package. It gifts us with 575hp at the crank. To achieve 50hp more than usual, Hennessey engineered new long tube exhaust headers in addition to Cold Air intake and an ECU remap. Sure, the sound will go from epic to insane when this script is finished. After all, Flat plane crank sung songs of its people better than any other muscle car engine. And Hennessey just improved it.

The Mail Order Update does not even cost that much. For 30hp and 20 lb-ft of torque more Hennessey charges $1,295 plus $40 shipping. That is $44.5 per hp.

And yes, Hennessey badge included. You’ll want to put it on the GT350R. After all, none of the upgrades here will void manufacturer’s warranty and it is simple to revert the car to stock specs if needed.

I do not have spare time. All there is is car time. 12 years and counting. I am a Central European gearhead, but you are probably thinking - aaa a disposable Borg drone! Well, actually, I like to dress up like James Bond too. The only thing I need to be him is an Aston Martin (and I love DBS more than DB5 because, reasons). That's something I guess.
