2013 ZL1 Pulley & Fuel System Upgrade

After becoming accustomed to the added power of an intake and header set up on his 2013 ZL1, this customer contacted us to add more boost and strengthen the factory fuel system. We baselined this car at a healthy 557 rwhp & 513 ft/lbs tq.

We turned to Fuel Injector Connection for a set of 1000cc injectors, and also topped it off with an MSD Boost a Pump. Using Metco for the pulley set up, we installed their overdriven crank pulley kit (which features an innovator’s west pulley), and also their interchangeable upper hub. This set up allows him to run appropriate boost for now, but also to turn it up later on if he adds a cam or heads!

The car then went back to the dyno, where it laid down 617 rwhp & 590 ft/lbs tq, for an impressive gain of 60 rwhp & 77 ft/lbs tq!

“Hi Kelly! I’m about 100 miles from Richmond and the car is running great! Beast mode lol! I wanted to thank you again for everything.. you and your staff are excellent and when I can save enough $$, I will be back for a cam! Take care!”
