Hennessey Hellcat vs Demon

By Andrew Nabors –  February 09, 2021

2018 Dodge SRT Demon vs. Hennessey HPE900 Hellcat Charger

Every automaker is on an electric push while Dodge has stuffed their supercharged Hemi into the Jeep Wrangler and the Ram TRX. To see how capable it truly is, let's watch a 2018 Dodge SRT Demon vs a new Hennessey HPE900 Hellcat Charger. For a quick refresher, the Demon was the most powerful muscle car in recent history. When the fuel tank sensed race fuel, it unlocked 840 horsepower and 770 lb-ft of torque. While this package was not offered on the 4-door Charger, they share the same architecture. While John Hennessey and his team have offered 1,000 horsepower examples for a decade, one lucky customer chose the HPE900 kit because it isn't as thirsty. Removing the upper and lower supercharger pulleys, their master technicians port the intake and fabricate an all-new stainless exhaust. Without removing the blower, heads, or touching the cam, the car receives a 200-mile shakedown along with a street-tune for the highest octane you can buy at the pump. This results in having 912 horsepower and 873 lb-ft of torque without having to spend big bucks on race fuel. Should the customer ever want to reach 1,000 horsepower, most of the hard work is already done. Tell us which car you would choose in the comments below and stay with us for all your Hennessey news.

Henny C8 Exhaust

By Andrew Nabors –  June 03, 2020

Hennessey Performance C8 Corvette Exhaust Screams on the ...

Engineers are forced to walk a tightrope when designing exhaust systems. Cars like the Camaro ZL1 and the Corvette ZR1 are not allowed to be sold in many foreign markets because they are too loud. They weren't meant for export anyway so we can enjoy the roar. However, the new C8 Corvette for sale was built as a global car. Therefore it has to be quiet to please everyone. Being a true-dual system from the factory, massive mufflers are needed to quell the beast. That is why John Hennessey and his team developed the first system with a crossover. Turn up the volume and listen to the Hennessey Performance C8 Corvette exhaust scream on the dyno. Hennessey Performance 2020 Corvette Sets New World Record PRO TIP: Exhaust crossovers make more low-end power than isolated "true dual" pipes. The opposing pulses also cancel each other out, so the car will gain horsepower, torque, and a great personality. Hennessey Performance spent hundreds of hours crafting this mirror-imaged system to have an optimal length. Not only is it appealing to the eyes, but it is also a truly tuned system, a lost art in the aftermarket. Your Corvette will lose 10 lbs while gaining 21 horsepower and 19 lb-ft of torque. Pricing is set at $3,495 plus shipping and the company is offering a special price of $2,995 for the first 100 orders. Learn More

Hennessey HPE1200 Corvette ZR1 Lays Down Incredible Numbers

As gorgeous and potent as the new 2020 Corvette is, the mid-engine layout is not for everyone. That is why the 2019 Corvette ZR1 will shine in the history books as a proper end to an era. It is still available as a coupe or convertible, with a 7-speed manual or 8-speed automatic transmission. In stock form, the supercharged LT5 engine offers 755 horsepower and 715 lb-ft of torque. Known internally by Corvette Engineers as BAS (Big @SS Supercharger), Chevrolet was able to make this power mostly with the larger blower. That is where John Hennessey and his team realized the car's potential. After working their magic, the Hennessey HPE1200 Corvette ZR1 lays down incredible numbers. After removing the supercharger, it is ported by hand. It is then treated to a larger throttle body and two new pulleys. The heads are replaced by a pair of ported ones loaded with bigger valves and stronger springs. Toss in a custom ground camshaft and you have incredible power. Automatic owners are forced to upgrade the internals to handle the power, but the 7-speed stick can take the abuse. The final step is a full tank of E85 and tuning on the dyno. This allows it to make 1,200 horsepower and 1,066 lb-ft of torque. If you choose to run this car on 93 octane pump gas, power is limited to only 1,100 hp. So what does this mean in the quarter-mile?

Henny Goliath Feature

By Andrew Nabors –  July 17, 2019

Hennessey Performance Unveils the 1st Production Goliath 6x6

Bob Berrard had a problem. He owns the largest potato farm in Wisconsin and he needed a new truck. A full load of spuds is heavy, even for a 4WD truck. So he decided to call our friend John Hennessey. Never afraid of a customer's request, the team delivered something massive. Taking inspiration from a biblical giant, Hennessey Performance has unveiled the Goliath 6x6. Starting with a Silverado High Country, the entire rear suspension is removed. In its place is their brilliant tandem axles which share a progressive leaf spring on each side. Four shock absorbers keep the ride smooth, even though it is 8" taller than stock. BF Goodrich 37" All-Terrains are wrapped on 20" Hennessey wheels. Other goodies include a roll bar, LED lights, powered running boards, massive brakes, and more performance. Adding a stainless steel side-exit exhaust and a cold air intake allow the 6.2L V8 to make 450 horsepower. Since the engine is nearly identical to the 6.2 in the Camaro and Stingray, you could always add more power if this isn't enough. Because Bob received the first example, only 24 trucks will be produced. The price of $375,000 includes a new Silverado (or GMC Sierra) and a 3 year/36,000 warranty.
