Well if you want another 100RWHP then you either need to go forced induction (blower) or a nice heads/cam combo to get up to about 460RWHP. Now hitting 460 means you probably need a decently sized cam so what are you looking for as far as driveability? A blower will drive like stock and have more power down low. Also it would be cheaper to go the N/A route versus the blower.

paxton does not make a kit for the v. I think the car would have to be pretty driveable wife drives it a lot. but we both like more power. i just think 75 to 100 hp would keep up with the new vetts and put a real beating on the father inlaws stage 3 roush. the v weighs about 3900 so it needs a little more. thank for hel and suddgestions.

You forced induction guys are straight bastards. 
Your throwing him right into the modding CRACK HOUSE... He'll be wanting so much more.
Actually either path will be a bit of a spend, and a chore to do. It's up to you which way you'd rather go.
Either way a Cam'd caddy with a "lope", or one with a super charger "growl", is gonna sound bad ***.

I have an 05 gto that I put headers and a maggie supercharger on. Went from about 350 rwhp to 477 rwhp. Maggies are easy to install yourself and very reliable power adders. Problem is that once I did that I kept wanting more, so now its an ongoing project and a money pit

Go with the blower...more $$$ on the initial outlay, but you keep the integrity of your stock engine, can re-sell the blower separately if needed and the car drives like stock when needed.
Andy at A&A Corvette got my LS6 to put out 593 RWHP on a stock engine...that equates to 700HP at the crank!!!
I did add a Methanol injection kit for safety, but the boost is set at a mild 6-7 PSI.

100%The rear in the CTS-V is marginal for stock power levels..... add another 100 rwhp not to mention the gobs of torque from a FI set up and your putting together a recipe for disaster in terms of rear end carnage. I would strongly consider this before modding since I can assure you it will void any factory warranty you may have, its not a cheap rear to fix either. If your looking for a little extra umph then you might want to consider some bolt ons and a good tune, it will be noticeable power but not too much as to where your gonna have to worry about tearing the driveline apart.

Yeah, always go from a 2nd gear roll. Sometimes you just can't. I agree with the SC guys. On a Caddy, the Maggie is such a nice power adder, and looks uber-trick. I don't even think you have to replace your hood, but not sure about that. Devil's advocate....a lumpy cam sound coming from a CTS in traffic would be way cool, assuming you have the exhaust system to announce it.

the car is under warrenty for a long time and i was on cadilacforms.com and there are a few dealer that are ok with modded car and will replace the rear because they know it was not built strong enough. there are some guy on there 6 or 7 rear. there is also someone who biult a steel case for the rear and justed finished it has a 150 mile on so far the whole cts v crowed is excited. more power no breaky.
