Vengeance Racing pushes the C7 Corvette Z06 LT4 horsepower record to 1088 wheel horsepower on the stock internals

[Sticky]

Incredible numbers here considering the factory blower is still involved. This is not boost only but it goes to show what the LT4 can take. Additionally, the stock fuel injectors and pumps are in the mix although methanol and a fuel cell are augmenting the fueling needs.

This is the mod list:

Halltech Carbon Fiber CKNZ
VR ported Throttlebody
VR 2.38 Upper Pulley Kit
VR Lower Damper (9% OD)
VR Stage III Custom Camshaft Kit-Retains VVT/Deletes DOD
American Racing 2" Stainless Long tubes with 3" ORX
B&B Fusion Catback Exhaust
RPS Triple Carbon Clutch with Tilton Hydraulics
RPM Level VII TR6070 Transmission
Driveshaft Shop Half Shafts
LG Motorsports Drag Spindles
VR Flex Fuel Sensor Kit
Alky Control Dual Nozzle Methanol Injection System
Nitrous Outlet 2 Gallon dedicated fuel cell
Nitrous Outlet TWIN Carbon fiber nitrous tanks
Nitrous Outlet Billet Bottle Bracket
NOS Launcher Progressive controller.

This would definitely not happen on an automatic or at least one that anyone expected to hold together so this is manual transmission with an upgraded clutch.

Fuel is E85 supplemented by meth injection and the fuel cell. A 41 nitrous jet produced 955 wheel horsepower and 936 lb-ft of wheel torque:

Upping things to a 57 jet pushed the numbers to 1088 wheel horsepower and 1079 lb-ft of torque at the wheels for the LT4 world record:

Huge numbers no doubt and it is impressive to see the LT4 holding this level of power but now what we want to see is this done boost only. Obviously the factory blower will have to be ditched for that to happen.
