compressor manifold ideas/questions

i have a couple questions about the stock compressor manifold on a 96 7.3 stroke. has anyone ever modified the stock y pipe b4 with out doing the intercooler way. i was thinking about a prototype stainless y pipe that i could fab out of 3" or 4" stainless pipe .... but heres the catch if you look at the stock y pipe it looks like it has a big egg shape with the two outlet pipes sticking out the under side. now i was wondering if there is a required mass of air that builds up in this space like the exhaust pipe on a 2 stroke dbike/quad where you build up the powerband. there is two ways i want to try... 1st would b like a big 4 inch can with the two 2 inch stubs out the bottem to make the y. 2nd i would try to make just two 2 inch pipes off a very short short splitter only like a inch long at the max. kind of like the exhaust on a old triumph. it would look like a thin capital a shape rather than y. any input on this would b cool. in my own head the there is only two outcomes. either it looses all the air mass that it needs to power the motor..... or in the worst case it will over charge the heads and blow the headgaskets or worse make the lower end of the motor explode. like i said im going to try and make bothmad:

I don't think that unless you are somehow going to fit a much bigger turbo that has a huge amount of air flow over what you have that the work to gain ratio would be worth it. If you made something like banks uses to plumb into the intakes with their intercooler system you might see a little gain.

I don't think your going to overcharge it, the turbo is only going to put out what its currently putting out. Even if you did use 4" tubing, the intake manifolds on the head will need to be modded. In my mind, you'll gain nothing but lost time in this.
