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...

  • Vengeance Racing custom spec camshaft- VVT retained/DOD deleted
  • Vengeance Racing Dual Valvespring Kit
  • Vengeance Racing Hardened Pushrods
  • Katech C5R Timing Chain
  • Comp 850-16 Lifters
  • Comp Cams Trunion Kit
  • Comp Cams Phaser Limiter
  • American Racing 1 7/8 Longtubes with CATTED 3" X pipe
  • All tuning in house using HP Tuner & EFI Live VIA Vengeance PCM




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)

Here is a short dyno video on the 62/33 jets


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​

beautiful! enjoy it while it lasts top dog ;)

I do have a question, you seen or heard of any diff issues yet? I've "heard" but haven't been able to confirm that the NOS car that ran 9s broke the diff doing it. I think it had the eDiff. You guys heard any rumors of that? NOS is going on mine too, so I'm not scurred lol just wondering if that was a legit rumor or not.

No diff issues here! And no confirmation on that rumor either. This is the first that Ron or myself have heard of it.

One of your posts said Pfadt headers and this one says AR headers & cats. Did you swap out?

Our car originally had Pfadt headers and X-Pipe. Since then, we have done header testing on Pfadt, ARH longtube and mid-length, and Kooks systems. We also tested catted ARH vs. non-catted ARH with no loss at all, so we left the catted X-pipe on. We stuck with the setup that made the most power overall, which were the 1 7/8" ARH.
