Has anyone tried to make a homebuilt setup like this work?

doesnt TPIS offer an ls6 intake with a oval shape mouth to match their oval TPIS 90mm TB?

the round TPIS 90mm TB that just came out is mostly to compete with the fast 90mm TB .... i heard that the FAST TB was having some minor issues

 

Yes, they have a custom LS6 intake with a larger opening grafted onto it and it works with their large (80mm x 90mm I think?) oval TB.
