Streetmaster to Airgap
I ended up installing a fabricated divider back into the Weiand for my sons 360 powered 78 Magnum as we want maximum torque and lower range power to move that heft.
I initially ran an opened up to 360 port window, deep ported, reworked and contoured plenum Weiand Action+ on my stroker and methodically tuned on things, knocked off et and gained mph ultimately removing the divider and seeing more gains to the point I ended up swapping to an AG and continued whittling away. Initially with just swapping to the AG (carb tuning required was minimal iirc) I knocked off about .15-.20 and gained 1-1.5 mph in the 1/8, I want to say about .20-.25 and 2 mph in the 1/4 over the ported Weiand. There was other testing and tuning with chassis so some of the et improvement was likely due to a few other things but the mph gains between the intake changes was definitely due to the AG. Only one way to find out what’s what! You never know until you try.:thumbsup:
