Dyno'd the Magnum.
Pretty awesome numbers! Are those the Mopar RT aluminums?
The Quickfuel Q-750 is what I'm running on my car. It seems to like it a lot. Driveability seems better than with my Street Avenger 670 if you can believe that.
The real Air Gap is worth a ton over the knockoff. My experience is only with the LA intake, but they're probably both the same.
