We recently had a client from Maryland contact us looking to build his C7 Grand Sport. Erin’s goals were to improve performance but also wanted to improve the looks under the hood. After talking over some different options we put together an awesome build list that met Erin’s needs. For this build we decided on our Stage IV Supercharger Package along with a couple additional options. This build featured:

• ECS Novi 1500 Supercharger system
• Vengeance Racing CNC Ported LT1 Cylinder Heads
• Vengeance Racing Cam Kit Plus with Stage II Camshaft
• American Racing 1-7/8” Longtube Header system with off-road x-pipe
• Vengeance Racing C7 Catch Can System
• Corsa Xtreme Axle-back exhaust
• Vengeance Racing powdercoated/Engraved valve covers with coil relocation

Once again our friend’s over a TPM Transports were called on to transport this beautiful Grand Sport to our facility in Georgia from Maryland. Once the vehicle arrived at our facility our technician got to work.

For this build we chose the ECS Novi 1500 Supercharger system. This blower coupled with the other modifications was a perfect option for a daily driven reliable LT1. To this we added our Vengeance Racing Cam Kit plus with our stage II camshaft and our Stage 2 CNC Ported LT1 Cylinder heads. Our stage II camshaft give an aggressive lope at idle while maintaining excellent street manners. Our CNC Ported LT1 Cylinder heads offer greater flow over the factory Cylinder heads. These also feature a multi angle competition valve job, Ferrea exhaust valves and come loaded with BTR .660 lift dual valve springs with titanium retainers. We also installed our C7 Catch Can system in gloss black and our Vengeance Racing custom valve covers with coil relocation to clean up the look of the engine bay.

With the install complete it was time once again to head over to our Dynojet Chassis dyno. With this combination Erin’s Grand Sport laid down an impressive 624rwhp and 607rwtq. This is combination made for a fast street setup while maintaining excellent reliability and drivability. With the build wrapped up and final number gained our customer flew to our facility to pick up his car and made the 12 hour trip back home
