Vengeance Racing C7 | 739RWHP/739RWTQ |Currently the most powerful C7 in the world! I tip my hat to Nitro Dave and his crew @ Nitrous Outlet for producing yet another high quality nitrous system!! We have been a loyal Nitrous Outlet dealer for many years and we are always impressed with what Dave delivers. Quality/Fitment/Performance always exceed our expectations. To be quite honest Dave has such an outstanding product and reputation that certain competing nitrous companies have to GIVE their product to shops to get them to use their systems.
For anyone not familiar with our current modifications...
Next up was the Nitrous Outlet Plate Kit. Knowing fuel supply could be an issue we decided to go with a Nitrous Outlet dedicated fuel cell as well.
Our complete kit consists of:
Nitrous Outlet C7 Specific Plate Kit
Nitrous Outlet Stage III Accessory Pack
Nitrous Outlet Dedicated Fuel Cell
NOS Launcher- Fully Programmable progressive controller
All of these items can be found on our online store if interested.
Vengeance Racing
Here are a few pics of the system installed on our C7. We actually removed the gauge attached to the fuel solenoid after setting fuel pressure and tuning on the dyno for a cleaner look.
The dedicated fits perfectly into the driver/rear storage compartment for a stealth install
Knowing that tuning the new Gen V LT1 was going to be different than previous Gen III/Gen IV LS engines/ECUs we started with a small shot and worked our way up...
35 Nitrous Jet and 18 Fuel Jet
112RWHP/136RWTQ gain
After reading plugs and reviewing the datalog we stepped up to a 52 Nitrous jet and a 28 fuel jet
169RWHP/197RWTQ gain
We made a few pulls dialing in the set up above then read plugs and switched to 62 nitrous jet and a 33 fuel jet.
226RWHP/290RWTQ gains
At this point we are out of tuning capability with the ECU. If we get an update from EFI Live or HP Tuner before our blower gets here we will jet up once more to crack 800RWHP ( or a piston, whichever comes first)
We will get to the track as soon as we can get some decent weather. Monday it was -3* and today its 40* and pouring rain.....
Stay tuned for more results as we continue to push the envelope on our C7. Next up we are installing an ECS system and meth kit. To keep things interesting we plan to leave the Nitrous Outlet system on the car as well

Excellent work guys!
Questions:
-Stock bottom end I assume?
-Stock intake?
If the answers to these questions are yes it will make 850 with an intake, 88 jet and a conservative tune.

It was a 150 shot to achieve the 739 number. The power falls off at the end due to running out of tuning ability. The computer has an odd "desired torque" issue that everyone is fighting right now. Hopefully we will have an EFI Live update in the next month that will clear all of this up.

That nugget of probably useless info out of the way, I got to see this car in person (not running though) this past weekend and it was gorgeous.
