Like I said in the original M1 post that intake surprised the heck out of me as delivered out of the box. I didn’t pick up anything like I usually do on an intake but I believe it’s going to be a much smoother flowing intake throughout the rpm range. I know how good a Victor340 can be with some work and because of that placed my Super Victor on a shelf to gather dust. I do know the Super Victor sure didn’t impress me the first time on the flowbench.
