We received our Halltech CKN system yesterday. After opening the box and inspecting the unit we went straight to the dyno.
As with all Halltech systems the CKN for the C7 is extremely high quality and looks amazing. I am not a huge "bling" guy, but the carbon fiber under the hood is awesome. If I wasn't installing an ECS blower next week I would be adding the carbon radiator duct and engine covers from Katech to compliment the CAI.
So back on the dyno we go. We make two baseline pulls to ensure our #s are consistent. We are down a few HP due to having the colder nitrous plugs installed, but we still manage 513RWHP/448RWTQ...
Leaving the car strapped in place we removed the factory air box and installed the Halltech system. Install was a breeze and we were ready to spin the rollers in less than 30 minutes.... Results blew me away!!! Our lil cam/header car obviously NEEDED additional airflow.
19RWHP/21RWTQ INCREASE!!!
For anyone who isn't familiar with our C7 modifications...
Halltech CKN Cold Air
Vengeance Racing Custom Camshaft Kit- Retains VVT/Deletes DOD
American Racing 1 7/8 Longtubes with CATTED X pipe
B&B Fusion Exhaust
Nitrous Outlet Plate System- Tested 50/100/150 HP settings
With these basic modifications we have picked up over 100RWHP @ 6000rpm and over 130RWHP @ 6500rpm....
This graph is the first pull our C7 made on our dyno Vs final #s with the modifications above.

Next up is a cam swap and an ECS blower. We also have several C7s in the shop right now for various modifications. We will post the results as they become available.
