We have been anticipating the release of the 2017 Camaro ZL1 for quite a while now, and are excited to see them finally rolling through the shop doors! This particular ZL1 came to us with just under 500 miles on the odometer, owned by one of our long time faithful customers. After coming out of a Kenne Bell supercharged 5th gen, AGP twin turbo 5th gen that he still owns and races with us, and several other fast toys, this ZL1 was one of the first dropped in Georgia and he knew that stock power just wouldn't be enough. We have big plans of 4-digit power numbers in the near future on this car, but in the mean time he wanted to see what we could achieve with the stock supercharger combination to be a fun and fast street car.
After having many years of experience with the LT4 engine in the C7 Z06 and CTS-V, the blue print had already been laid out for what we needed to do to push the LT4 engine and 1.7L supercharger to their potential reliably. As it is with most of our customers, a heavy hitting camshaft had to be the foundation of the build, but something that was still extremely streetable. We reverted to our Stage III performance package for the 2016+ CTS-V as the foundation for the build on the ZL1, as well as the addition of a dual nozzle methanol injection kit and E85 flex fuel sensor for an added bump in power when the fuel was available. Lastly, a set of BMR lowering springs were added to set the stance up and help the car look as good as it performs!
The total modification list used includes:
- Vengeance Racing Stage III Camshaft Kit
- American Racing 2" Longtube Header System
- AldoWeld Cold Air Intake Kit
- Vengeance Racing 2.38" Upper Pulley Kit
- Lingenfelter Balancer and 9.17" Lower Pulley
- Vengeance Racing Flex Fuel Sensor
- AlkyControl Dual Nozzle Methanol Injection Kit
- BMR Lowering Springs
After the installation was complete, we headed to the dyno to complete the tuning on both fuels for the car. After baselining at 553rwhp and 487rwtq, our final end result on power was an extremely strong 708rwhp / 628rwtq on 93 octane, and 759rwhp / 651rwtq on a 70% content of E85! This was a total gain of 206RWHP and 164RWTQ over stock while still at a conservative boost level and timing!
The car was delivered immediately after installation to our friends at Glasslife Atlanta for a full paint correction and ceramic coating service to protect the exterior surfaces of the car, and we are looking forward to a full photo shoot once this is complete very soon. Stay tuned to see performance results from this car at the upcoming WannaGOFAST 1/2 mile event in May at Heaven's Landing in Clayton, GA as well!
