In this "before" photo, you can see the restriction imposed by the stock inlet elbows and stock MAF meter. This is how we ran Magnum TPI at the track for its best-to-date run of 12.30/109.4. The heavy-breathing 396 tuned-port motor had already been converted to speed-density via a Gen 7 ACCEL/DFI, but the MAF was retained for plumbing. A 3-inch "Home Depot" PVC pipe and 3-inch conical K&N filter did alleviate some restriction, but it was still far from ideal.
