im designing an UIM
 

Yea im in the middle of designing an upper intake manifold, and probably a lower manifold, With the upper i was trying to utilize a bigger, better flowing throttle body. ive got it all drawn up on Autodesk Inventor, the only thing im still trying to figure out is what to do about the TPS. other than that its all done. as for the lower im still in the planning stage i know im going to design it with 4 injector bungs for more even distribution of fuel. I just started getting supplies in to start the building process. if anyone has any suggestions or anything please feel free to say something. im definitely looking for input on the matter.

Lets see a drawing of the throttle body to see how the tps can be installed .

Unless your doing this to run over 700 hp it is pointless, it will look good though...
The stock UIM is very well capable of going over 700hp...
Would like to see your design though as I would like to change mine as I don't like the look of the stock one...

As for the TPS just look at the stock TB and try to incorporate that in your design.

Do you plan on having these casted once the final product is made? I mean there is alot more work to take into account when designing something that complex. I hope you would flow bench the system to see how much better it is than stock. I would like to see the drawings as well.
