Fantastic
I do indeed sam its a large port to small port to allow for the stepdown of the bjx head i want to keep it in ass it keeps the inlet temps way down and i find it helps.Have you a phenolic gasket between the head and inlet mani Jack?
Suppose you need it for a smooth transition from large to small port. Every little helps with flow so may as well keep it, just be interesting to see a difference in dyno figures between your intake and a normal BAM one for example.
maybe not best for you to remove your injectors too often though, can’t have you burning your eyeballs each time
Would you not be better just enlarging the ports on the head and giving them a wee polish while you're there? Not a massive job to do and will improve flow a great amount.
You could enlarge them ports no problem at all. Essentially all you're wanting to do is match it to the gasket and manifold to make the flow as smooth as possible. Nothing worse for air flow than hitting a flat surface.
But you don't want them too big either, they need to match the actual flow through the engine.
I guess all this tedious flowbench work and actually measuring stuff and doing some actual calculations is overrated these days, just get a dremmel in there and work away
Ill get a few sent through tomorrow butLooks great! I've it on good authority it sounds good on boost.
Need videos!
