Cts-v

[daviebushongjr]

I have a 2004 Cadillac CTS-V with some small engine modifications, like air intake, custom exhaust, and a preditor tuner. I woild like to know what external bolt ons we can do to get me as close to 400 rwhp as possible.

How much power do you have right now?.. What do you consider an external bolt on?.. Simple bolt-ons wont net huge gains..

Oh and welcome to LS1.com..

not sure what power car has now. wasnt looking to do cam or head work

[Cutlass]

Long tube headers, catback exhaust without cat converters, air intake, port and polish throttle body, FAST intake manifold, and a dyno tune should get you in the 375 to 390 RWHP range.

What Cutlass said.

nice to see another cts-v on the site

a maggie will get you well past that and I think would be emissions friendly for Cal

Maggied CTS-V...mmmmmmm *Homer Simpson voice*

And then you need to invest in a couple replacement rear diff center sections because those things are weaker then the F-body 10 bolts. And I'm not aware of a drop in upgrade yet, but there are a couple custom rearend upgrades out there. Big $$$$

maggie?

[jetaws6]

magnacharger you see alot of them on gtos. make excellent power with a little bit of boost. I know a guy making 500 rwhp with a maggie on 6lbs of boost and long tube headers on his ls2

I didnt know that was possible lol

I was told the rear in the CTS-V and GTO were stronger than the 10 bolt.

Welcome from Livermore.
If you don't mind swapping out the headers every 2 years those will get you close to your goal.

I was told the rear in the CTS-V and GTO were stronger than the 10 bolt.

I may have exaggerated a bit. But, yes the GTO rear is stronger, the 1st gen 04-07 CTS-V rear isn't too great. Ring gear diameter is 7.625" (same as the F-body 10 bolt). So, put a weak 10 bolt in an aluminum housing behind an even more power LS V8 engine and BOOM. They blow up.

I have heard horror stories about the CTS-V rear. Some folks have told stories about 5k launches and then BOOM. The new design took me by surprise as the rear is more offset to the driver side and one axle is shorter and of a larger diameter than the other to offset wheelhop.
