Hennessey Upgrades the 2011 Nissan GTR800 image

For some time, Hennessey was holding its steps to lead forward due to a number of different models such as Cadillac Escalade, Dodge Ram HPE500 and the very recent but attractively tuned Nissan GT-R.

The major focus of tuning the Nissan GTR800 was on the power of the vehicle. Hennessey has added a standard 3.8 liter V6 engine that produces 800 horsepower. As compared to the last tuned up project what Hennessey had brought out, the new one has got more attention under its hood. Where the standard engine produces 800 hp, the additional power comes out due to the following upgrades.

  • SUMOTM Turbo upgrade
  • SUMOTM Stainless Steel Midpipe Exhaust
  • SUMOTM Intercooler Piping Upgrade
  • SUMOTM Stainless Steel Turbo Downpipes
  • SUMOTM High-Flow Cold Air Induction
  • SUMOTM Intercooler Core Upgrade
  • SUMOTM Inlet Piping Upgrade With Blow-Off Valves
  • SUMOTM Wastage Actuators
  • Modified Factory Mass Air Sensors
  • High Flow Fuel Injectors
  • All Necessary Gaskets and Fluids
  • Chassis Dyno Tuning and Engine Calibration
  • Serial Numbered Dash and Engine Plaques
  • Hennessey Premium Floormats
  • Hennessey and GTR800 Exterior Badges
  • Clutch Pack and Transmission Coller Upgrades Recommended
  • 1 Year/12,000 Mile Limited Warranty

Due to these modifications the car will get more power of 813 hp and can make 0-60 mph in just 2.6 seconds. Besides, 0-100 mph can be made in 6.2 seconds. Apart from this, Hennessey has also kept the optional upgrades such as:

  • SUMOTM Electronic Exhaust Cutout (75 mm)
  • kW Variant 3 Adjustable Coilover Suspension Upgrade
  • Transmission Clutch Pack Upgrade
