THE ENGINE DYNO RESULTS ARE IN! 150HP MORE THAN STOCK LS3!
Here is our latest testing of the LS3 / L99 MAX Performance Head & Cam Package.
We’ve taken the goodness of the LS7, and adapted it to the LS3 / L99 platforms, to create a package that is the best of both worlds! The MAX Performance Package is built with an LS7 Cylinder Head, which lets us run a smaller combustion chamber, with additional piston to valve clearance, and still run a lot of camshaft. This seems to be the perfect combination.
After many months of working in secret – we are proud to introduce the GPI MAX Performance Head & Cam Package for LS3 / L99 applications!
This package is not for the faint of heart. With a huge powerband, torque down low, and an explosive LS7 top end – this is a no compromise NA build.
This first test build made 542rwhp, and we’ve just started working on the next build #2!
