Henny C8 Exhaust

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? Tell us what you think of this car in the comments below. For more information email sales@hennesseyperformance.com or call 979-885-1300 " width="680"> Check out the wheelie @23 seconds!

Hennessey HPE1000 Corvette ZR1 vs Ferrari 488 GTB

When validating your latest build, it is nice to have a twin-turbo Ferrari for comparison. Previously at Hennessey Performance, their HPE800 Escalade went head to head against a worthy opponent. Now they have upped the ante with a Hennessey HPE1000 Corvette ZR1 versus a Ferrari 488 GTB. We don't know if the Italian is the same car as last time, but it doesn't matter. The Ferrari 488 GTB offers 661 horsepower and 560 lb-ft of torque. The opponent is the most powerful Corvette that Chevrolet has ever sold. In stock form, the Corvette ZR1 has 755 horsepower and 715 lb-ft of torque. Known internally by Corvette engineers as BAS or "Big @SS Supercharger", it was a proper farewell to the front-engine chassis. Those are good numbers for a production car, but we all know Hennessey can deliver more. Ferrari 488 GTB vs Hennessey HPE800 Escalade Starting with ported heads, the car receives a new cam, supercharger pulley, and a full stainless exhaust. Automatic cars need new internals for the 8-speed, so the 7-speed manual is a more affordable conversion. Measured on their dyno, the power at the crankshaft is 1,000 horsepower with 966 lb-ft of torque. If you want more, the car HPE1200 is tuned to run exclusively on 110 octane race fuel to unlock 1,200 horsepower and 1,066 lb-ft of torque. If you want your ZR1 to break the sound barrier, our dealers have a few 2019 examples still available. Click the link below to find yours and stay with us for all your Hennessey Performance updates.

Hennessey Corvette ZR1 Breaks 1/4 Mile Record

Hennessey Performance truly enjoys leveling up cars through their upgrades. For the Corvette ZR1, they have the HPE1000 upgrade which most definitely levels up the American supercar. When installed, the HPE1000 package pushed the car's output all the way up to 1000 bhp and 966 lb-ft of torque. When the car is equipped with drag radials, Hennessey says a ZR1 with the HPE1000 package can run 0 to 60 mph in just 2.3 seconds. To test out their work on the ZR1, Hennessey took one with the HPE1000 upgrade package to a drag strip to see how fast it could complete a 1/4-mile sprint. When the car crossed the mark, it recorded a sprint of 9.52 seconds @ 144.8 mph. According to the Texas-based aftermarket tuner, this is a new world record for the ZR1. Check out the video of the sprint by clicking play above. see all zr1's up for sale Also Check Out: 2019 Hennessey VelociRaptor Ranger vs Stock Raptor McLaren Senna HPE1000 from Hennessey Performance The Rock’s New Hennessey VelociRaptor V8

Hennessey HPE 1000 Corvette Grand Sport is a Supercharged...

If you like the looks and performance of the Corvette Z06, the Grand Sport has all of its features without the big engine. It bridges the gap between the base model Stingray and the Z06, and the LT1 engine offers 460 horsepower. If that is not enough for you, the Hennessey HPE1000 Corvette Grand Sport is a supercharged beast. While most superchargers have moved into the intake valley, centrifugal blowers have made incredible advances in recent years. Starting with a new 416 ci (6.8L) short block, HPE adds cnc ported heads, stainless headers, and several internal upgrades to the 8-speed automatic. The engine and transmission computers are tuned on the dyno before a shakedown at the Pennzoil Proving Grounds next door. This comprehensive upgrade makes 1,008 horsepower at the crank and it is available for manual transmission cars also. Faster and more affordable than a ZR1, the HPE1000 is waiting for you.

2019 Corvette ZR1 Arrives at Hennessey, Gets Dyno Tested

The new 2019 Chevrolet Corvette ZR1 has finally landed at Hennessey Performance. Now, the company will get to work so they can start pushing more power out of the 6.2-liter LT5 supercharged engine. As a stock vehicle, Chevrolet says the ZR1 will lay down 755 horsepower and 715 lb-ft of torque. But Hennessey's version will definitely be more powerful, but they've got a few things to do. For starters, the workers needed to get behind the wheel so they could take the ZR1 out for some high-speed runs. I'd be wrong if I said I wasn't jealous of them.4,000 Horsepower Corvette Takes Flight, Sticks the LandingNext up was the dyno test. This is where the team was able to mash the pedal down and get a read of what they're working with. Interestingly enough, their dyno results showed max power at 654.64 hp and 645.20 lb-ft of torque. Hennessey says their HPE1000 supercharged engine upgrade will bring the ZR1's power all the way up to 1000 bhp and 966 lb-ft of torque.
