Speed Society once again welcomed our team with open arms as we made our way back to sunny San Diego just before Thanksgiving to put together an extreme performance package on a recently purchased 6th gen Camaro ZL1. The goal on this build was to take performance just one step further than the previous Z06 build, as well as offer a more unique underhood aesthetic flare to make the car perform equally well both on the track, and at the local car shows and cruise-ins. Being that the previous car essentially maximized performance on the stock 1.7L LT4 supercharger, we knew that we had to add something special to the engine to help push the bar even higher on power. This was done with the addition of Whipple’s all new Gen 4 2.9L supercharger, as well as Lingenfelter’s all new high-side fuel system and DSX Tuning’s low-side fuel pump kit so that we could run up to 15psi on boost on both 93 octane and E85 without the need for methanol injection!
The rest of the build was centered around our Stage 4 performance package that offers a set of LME CNC ported LT4 cylinder heads, custom hydraulic camshaft kit with VVT-delete thanks to the LME front cover, and a full Kooks header and exhaust system for both flow and sound. Boost was provided by the Whipple 3.5” upper pulley as well as the addition of an ATI harmonic balancer and DSX Tuning 9.06” lower pulley wrapped by a Gates Green HD supercharger belt to minimize slippage and belt failures. To cool intake air temperatures at this boost level, Weapon-X Motorsports provided their “Triple X” heat exchanger upgrade kit that substantially lowered temperatures as well as offered quick recovery on the track. Lastly, our custom billet valve covers were powdercoated in a red finish to match the supercharger and installed with our coil pack relocation kit to really dress up the engine bay.
