DYNO & TRACK RESULTS

DYNO 1: Stock 48mm TB, JET airfoil, ported plenum, SLP fully siamesed runners, Edelbrock base not  ported, stock 1987 Pontiac GTA 5.7L bin
                 and Accel 24# injectors set at 46 psi.

DYNO 5: Swap to the HSR only. 46 psi.

As you can see it just traded where the power band is at. Also, the air/fuel ratio has went very lean starting at 4200 rpm. This is due to the increase in volume of air this manifold can flow. With additional tuning there is more power to be had in the upper rpms. But, I wanted to show what would happen just swapping to the manifold only.
