Ill definitely flow it just to see what it does and if it does come out to be of definite gains I may make another one and actually see how it performs. Im not really trying to get into the parts manufacturing to much but if they come out to be a quality peice then I may make some more to help me pay for books, tuition and some other bills Ive got.
Yea, previous post was somewhat of a drunken rant, so I appologize if it was rude. But in all seriousness, deveolping an intake manifold can be tricky. There are a lot of factors to account for and some pretty complicated equations to work out. In the end, you want the air to travelling at sonic speed (almost choked) as it travels down the intake runners/head for maximum efficiency (in whatever part of the powerband you wish). Thats where all the runner length, diameter, air flow, and plenum volume factors come into account. Then you always want to reduce head losses (friction), so you incorporate items such as velocity stacks, cylindrical plenum, etc...
Either way, I think fabricating an intake manifold like yours will be a great experience. I always encourage people to do their own work, it helps people really understand how things work. I would try and find some of the velocity stacks I was talking about though!
