Disclaimer: the title above should've contained "once again" and that's thanks to the fact that Hennessey is not at its first Venom 1000 package.
The Texan tuner also played with a Viper about a decade ago, working on the Gen 3 (it was actually the pre-facelift second generation) Dodge supercar and upping the ante to a rounded 1,000 horses.

With the Gen 5 Viper (you know, the third generation), the Lone Star State aftermarket developer has taken things even further, punishing the rear wheels with 1,120 hp at 6,200 rpm, up from the factory 640 naturally aspirated hp (the company says its kit covers the 2013-2015 Viper).

As for the torque, this jumps from 600 lb-ft to an asphalt-damaging 1,092 lb-ft (1,481 Nm). Given the standing start traction issues such muscle brings, we'll warn you that the standard performance numbers, as listed by the company, won't reflect the entire real-world potential of the machine.

Hennessey explains the 0 to 60 mph sprint is covered in 2.7 seconds, while the best quarter mile attempts saw the TT Viper pulling a 9.7s run at 152 mph (245 km/h) - these figures were achieved using drag radials and the prepped surface of a drag strip.

Unlike in the case of the previous Venom 1000, Hennessey didn't stroke the V10, so it only comes in the standard 8.4-liter configuration. Given the forced induction conversion, the tuner has lowered the compression ratio.

Let's go through the complete set of changes made to the car:

• Forged Aluminum Pistons (9.2:1 compression ratio)
• Forged Steel Rods & Wrist Pins
• ARP 2000 Rod Bolts
• Thermal Coated Rod Bearings
• Computer Balanced Rotating Assembly
• Twin Precision Ball Bearing Turbochargers
• Front-Mounted Air-to-Air Intercooler
• Polished Stainless Steel Inlet Tubes
• Custom Intercooler Hoses with T-Clamps
• Stainless Steel Turbo Headers
• Stainless Steel Turbo Down Pipes
• External Wastegates
• Stainless Steel 3 Inch Exhaust System
• Upgraded Fuel Injectors, Fuel Pump & Lines
• Upgraded Fuel Pressure Regulator
• All Necessary Gaskets & Fluids
• Engine Management System Upgrade
• Engine Management Calibration
• Hennessey Shift Knob
• Hennessey Premium Floormats
• Hennessey® Exterior Emblems
• Venom® 1000 Twin Turbo Exterior Emblem
• Serial Numbered Dash & Engine Plaques

There's nothing mentioned about the transmission department. If the stock Tremec six-speed manual was left untouched, it means the gearbox is the one the sets the limit here.

The upgrade has been ready for a while, but since Hennessey likes to play the Easter Egg game, we haven't noticed it until now. Oh well, we guess it's never too late for such an octane behemoth.
