88turboma71 said:actually i have read the flow chart. i see the turbo can flow enough for 680 horse power but the exhaust housings that u can get with it are limited to an
a/r .68 or a 1.06 according to the guy i spoke to at precision and i was thinking about using one in the .70s, so a .68 may not give me enough at the top and a 1.06 may not give me enough at the bottom
My GT4082 has an .81 a/r.
