Newb with FI on 347 Questions... Hey guys, Ive been lurking for a while in the Classifieds and searching through old threads but I have some general questions still. Forgive me if I am sounding like an idiot or overlooking an obvious thread with these answers.
I am looking at an 05 CTS-V with a D1SC on a stock bottom end LS6. Car is running 7lbs of boost right now, the cam specs are 231/235 .617/.621 115 4 and is running stock heads with PRC .650" dual valve springs. Car has a FAST 102 intake and Nick Williams 102 TB along with LSXR fuel rails, siemens 60# injectors and a Kenne Belle Boost-a-pump.
I am looking at different options for 'turning up the wick' so to speak, the car dyno'd at 562/461 with this set-up. I am gathering that at a bare minimum more boost will necessitate better rod bolts, forged rods and pistons. With this mod only, what can I shoot for boost and power wise? Would the stock heads become the next major limitation? Is this fuel system capable of 10-14psi or 600-650+whp/500-550wtq? Which for now is probably my goal unless costs get overly prohibitive. Im sure I have more questions, but this is a start lol
Thanks in advance...

Putting in forged rods/pistons will make the motor safe for north of 650rwhp, how much, who knows, but it's won't be your weak link. Your biggest concern is probably going to be the fuel setup. I'm not familiar with the CTS-V's fuel setup and how much volume a stock pump plus boost-a-pump will support.
