Hennessey Performance Customer Testimonials

"The car is awesome and the power is unbelievable. Hennessey did an outstanding job on turning my Camaro SS into a real hot rod. I have had people flag me down to look and take pictures of the car and engine then begging to go for a ride. It should be against the the law to have this much fun. Again an OUTSTANDING JOB!!"

"You guys did a great job. I just can't get enough of driving my Vette. It attracts a lot of attention. People are always taking pictures and video of my car...it makes me feel like a celebrity!"

Ed S. from Chula Vista, CA
2014 Chevrolet Corvette Stingray
HPE650 Supercharged Upgrade

"It gets lots of thumbs up when I'm driving it. It is a fun ride that has power to spare. My wife, Wendy, is amazed at how many people stop and ask about the car and the Hennessey package. I have to thank Good Chevrolet for informing me of the HPE 650 package. Hennessey makes a great addition to a great car! The car is a 2010 2SS with RS package. It is metallic blue with custom painted silver stripes. It also has the Hennessey/Corsa exhaust addition."

David Y. from Renton, WA

HPE650 Supercharged Upgrade

"Thanks to the Hennessey team for putting the HPE650 package in my 2013 GT Premium. This monster is not for the faint of heart. It’s everything I expected and more. I was quite proud when I attended the Charlotte motor speedway Mustangs 50th celebration and with thousands of mustangs there people were stopping at my Hennessey to get photo ops. Love my Hennessey!"

Steve T. from Katy, TX

HPE650 Supercharged Upgrade

"I very much still love my 2013 Charger R/T Road Track 5.7 HEMI upgrade to the HPE500. It seriously performs as advertised. I can't tell you how many people ask about it. I have even been stopped in traffic with a driver wanting to know about the HPE500 badge!"

Russell H. from Cypress, TX
2013 Dodge Charger R/T
HPE500 Supercharged Upgrade

"That's my car and it IS A MONSTER!!! If you think it looks good you should drive it and hear it. I can't go anywhere without a crowd gathering to admire it and ask a ton of questions. If you have a need for speed Hennessey Performance is the place for you. You will not be disappointed. Bring diapers!!!"

It's been 48 hours since you returned my McLaren 12C. After any period of time, one would imagine that any excitement provided at the beginning would start to wear off. In fact, just the opposite has occurred. I gave you an extremely fast car, and was given back a starship with advanced trans-warp drive. The difference in the performance of the car is so astounding that I've been driving with a shit-eating grin for two days. If I made a plaster mask of my face, it would look like the Joker out of Batman.

As you know, I've owned four Ruf Porsches including the famous CTR "Yellow Bird," two Carrera GTs, a GT3 RS, a GT2 RS, two Ferrari F40s, a Ferrari F50, two Aston Martins, including a 430 GT1, two Ferrari race cars, including 430 GT1, and yet nothing has come close to the blinding speed that you have produced in this particular upgrade with my McLaren. I just wasn't expecting that much of a difference. For the first time in my life, and I mean really the first time, I might actually have achieved fast enough, and that is a place I never thought I'd reach. After all, why would anyone mess with the square root of exhilaration? Thank you, John, for making the fantasy a reality. I know, with infallible certainty, that every time I get into the car, I'll piss in my pants laughing.

"Good morning! Just a quick note to let you know how pleased I am with the work done on my car. I have to tell you I was more than a little skeptical that the changes being made would make any significant difference. I was totally wrong, more than pleased. I was especially pleased with how professionally everything was handled.

Everything I was told would be done, was done, the car was ready when promised, the price did not change, the vehicle was detailed, etc. etc. etc. It was a pleasure doing business with your company, if I can ever assist, please do not hesitate to ask."

Best regards,

"The car is phenomenal! Nothing compares to the fun I have had in the two weeks I have owned my 45th Anniversary Convertible HPE650! The car is beautiful (with the wheels and polished super charger) and it is by far the strongest car I have ever had the pleasure of driving. I get looks everywhere I go. I even had a guy stop me at Lowe’s to look at it. He could not believe the sound.

"I entered “Earthshaker” in my first car show ever this past weekend in Richlands, NC. It took 1st Place in the 2000 – newer category! There were other people there with stacks of trophies in front of their rides. They had some great looking custom Corvettes and even a few other Camaros.

"I could not be happier than I am telling people about Hennessey Performance and quality work you guys do. After spending 11 years in the Marine Corps with countless deployments, I require hard work and attention to detail. You guys gave me everything I require…and more! Thanks for everything and you have a customer for life!"

"Just wanted to tell you guys I installed the HPE Air Induction system and the programmer combo I purchased from you guys and wanted to let you know that it is AWESOME!! The throttle response is so much quicker and it just made the truck come alive so much. I appreciate all the phone help too, and next on the agenda is to get you guys to install the supercharger for me. Have a great day and you made a customer for life!!!"

Bill F. from Louisiana
Ford F-150 Raptor

"I have been trying to find the exact words to send to you all regarding the car. I have to tell you that I am still not sure what to say other than, WOW.

The car is a real joy to simply cruise around in and a total rush when I get on it. We absolutely love the look and sound of it. It looks fast just sitting in the driveway and puts any doubts to rest when I start it. This car rocks. 

My 23 year old called it sexy and wants to include it in some of her wedding pictures. I know "Sexy" was not the first word I thought of, but, I can see how she came to that conclusion. We have only had it out a couple times so far and have already received accolades from a Shelby owner, an original Cobra owner as well as a Z06 owner. Heck we even got an applause from the neighbors.

Everything about the build has been incredible. You guys and your team are topnotch and professional through and through. "

Emory, M. from Illinois
Supercharged HPE650 Camaro

"I bought an installed your Max Boost 445 upgrade for my 2011 Taurus SHO earlier this year and I love it! It’s a true sleeper and my friends with their “muscle cars” can’t stand it because my “family car” as they call it will just simply beat them hands down. "

Brad H. from Arkansas
MaxBoost 445 Taurus SHO

"Started her up and the cam sounded perfect. She purred perfectly at 900rpm with no hiccups. Slipped it into first gear and rolled out of Hennesseys, keeping it in first to see if any surging or uneven idles were prevalent. Nothing. Felt stock even. Getting onto I-10 I bring her up to 3500-5000 rpms to test out the new setup. The stock exhaust with the headers is a perfect note. Not too loud... Not too quiet. The boost comes on strong, clutch and transmission feel great and the mid range of this car is simply insane compared to stock. Cruising again at around 65 I put her in 6th gear to see if any surging takes place and again nothing. Thinking to myself this has to be the most tamed "cam modified" cars I have ever owned. Not a blurp anywhere at any rpm. I test out the new suspension setup that Hennessey offers. It honestly feels as good if not better then the ZR1. No popping, rubbing just squat and go.

I get her back home in the garage and look back at the stance, muscle and luxury this car offers. What a machine. For the money you have a 4 door 700hp sedan with an interior that rivals most super-cars and the performance that is on par to some of the fastest production cars in the world. I am even tempted to sell the ZR1 knowing its not going to be driven any more with this sitting next to it.

If anyone is in the market and owns a CTS-V in the Houston area feel free to contact me and I can let you experience this car first hand. Thanks again Hennessey for one amazing machine!!"

Garrett O. from Texas

"The HPE 650 fulfilled more than my expectations my friend,driving it hard or just cruising is a delight. Everything is just perfect but the sound of the exhaust is the best compared to many exotic cars. I have driven and owned Porsches, Lambos and Ferraris but none have what American Muscle cars have, especially if it's upgraded by Hennessey!"

Taher Y. from Panama
Victory Red 2010 HPE650 Camaro

"Driving down the freeway yesterday and I got more thumbs up with this than I do in my Bentley or Ferrari."

Jim G. from California
Aqua Blue Metallic 2010 HPE550 Camaro

"WOW.... This thing is a race car with a/c and a radio, and I don't even listen to. I would rather hear it lope at idle every time I stop at a light. I can't even get gas without drawing a crowd it sounds so good.It looks great and sounds even better."

Devan A. from Texas
Victory Red 2010 HPE650 Camaro

"Well, my baby got home today. We spent the day getting to know each other. Words can not express the power and performance of this machine. It passes all I had ever hoped. The quality of the work and care taken by the crew cannot be matched. Thank you and your crew over and over again.
I love it."

Marshall K. from Tennessee

"Hennessey has preformed above and beyond my expectations. From sales (James H.), to all the guys in the shop. I’m looking forward to my next upgrade."

"My Jeep is amazing. In fact, it's the only one I drive these days. Never got a chance to race Shaun White, but it's fun to blow away every other car in north county. It's running sweet!"

- Tony Hawk, CA


"I wanted to thank you for the superb job that was done on my viper on this build, It sound and runs great, You have a great team of guys that work for you. JT was very helpful at all time and Jason as usual did a great job and treated me like family, I look forward to the next build, Happy Easter."
