i just switched from a stock ls1 intake and stock tb to a bbk intake and 80mm tb. my dyno numbers went from 365hp 332tq to 386hp 345tq and my et went from 12.20@111mph to 11.82@115mph

pretty straight forward. you have to replace one valley cover bolt on the back passenger side with a button bolt that comes with the intake. on the weiand i noticed that all the machined edges are sharp the the intake uses paper gaskets. the bbk is smooth all over and has plenty of room to be ported. i am very happy with it. i have not seen many ls6 swaps even with tb net a .4 and 4mph gain.

He used to be a sponsor here that did hella business as a tb porter and also cylinder heads. He stopped because he got too busy, but I think he takes on projects... good guy. ~Joshua
