Looks nice so far.
I read in your other post, you are only looking to make 400 HP???
If that is the case,this turbo manifold is a bit overkill.
You can make a plane jane log type manifold for 400 HP.
But since you are making a nice manifold & you are probably having fum making it,as I would also,keep it up,you are doing a good job!
B.T.W.,those are stainless schedule tubing,how much have you spent on materials so far?
