Intake size

I’ve had the Super Victoria and the original M1 on the dyno back to back and they made with in two or three numbers from 3000 to 6500 rpm. The Super Victoria made a couple more hp on the top end and the M1 made a couple more numbers before 5500.
This was all on a 650 hp 440.
I like the looks of the Victor but the original M1 has a much easier fit especially under the hood with no noticeable power loss and better filter options.
