Thread: Good intake manifolds or knock offs??

  1. #1
    I am in the market for a single plane intake. During my research I keep seeing the Porfessional Products manifolds and am curious if any one has run one, more specifically run one back to back against a "very similar" design from a reputable company on a motor or flow bench, dyno etc.
    I know you get what you pay for and I've paid enough so I thought maybe I can get by with a different approach this time. Let me know your experiences and perhaps we can discuss the details.
    And now the merlin
    Now the victor
    Just seems as though they are really close. I called the company and they said "well you know there are only so many ways to make a single plane intake..."
    I asked if they did a 3D scan and re-engineer the parts and their answer was "no" So with all the aviable info and choices, what is a guy to do??
    19' hallett 1800lbs (weighed it last week) 489 BBC solid roller 246 .622 single pattern, 9:1 and a 950 HP DP,air gap manifold, no spacer. Thru transom rewarders. Currently pulling a worn out pump to 5400 at 75 on radar, with the water breaking just behind the dash...(don't worry, pump and set up are next)
