    Default 2011 CTS-V Modding

    In May 2016, I traded in my manual 5th gen SS daily for an auto CTS-V (V2) sedan, non-Recaro car. 2 tone interior, painted silver wheels, sunroof, nav, and all the standard options like big brembo brakes, mag ride, etc.

    These are rated at 556HP at the crank at around 6000-6100rpm I believe. I bought the car with an Airaid CAI and otherwise stock. I'm the third owner. An old lady bought it new and racked up the miles, then a middle age couple bought it as the wife's sunday driver. I grabbed it with 25k on the nose and it sits at 33k, nestled in a garage for the winter.

    For anyone wondering - yes, the T/A project is in full swing and exciting things going on there, but I like to live dangerously and have a few projects going at once.


    So here we go - a thread dedicated to my LS daily.

    2016 mods:
    - CAI
    - Street Tune (HP Tuners, done with a wideband obv) by DiabloFormula Racing. We leaned it out a bit, but it's still pretty fat.
    - "Valve mod" - free mod that's common in the LSA world.
    - Dipped front grills in black plus clear
    - PowerStop carbon ceramic pads (GREATLY reduced brake dust and noise)

    When I'm a little more awake, I'll link the dyno video. A local shop just set up a Land & Sea dyno, which is a serious heartbreaker for those only familiar with Dynojet numbers (like me). The car made like 451rwhp at 5800rpm and they didn't run it past that.

    2017 mods that have been PURCHASED:
    - 2.5 supercharger pulley, hub & solid isolator
    - Catch can (Vadder)
    - Chinese stainless longer tubes and offroad X
    - plugs, wires, sleeves, gaskets, o2 ext, stainless hardware, may get some band clamps yet
    - Differential fluid change
    - Motor oil change
    - Green air filter
    - Dipped wheels
    - Interior/exterior LED swap
    - M105/M205...the detailers will know what's up. This car is ROUGH! I'm very unhappy with the quality of the paint/clear. It's a giant eye sore and pisses me off that the previous owners couldn't take care of the car properly. /rant

    Some things I'm on the fence with right now:
    - Fuel injectors likely will go to FIC
    - I want a nicer HID headlight bulb and matching fog setup
    - This is basically the "stage 1.5 mod list", but "stage 2" may be later this year, after the T/A is back in action. That will consist of heat exchangers, lower pulley, idlers, and some other odds and ends. I want to do a cam and ported blower/snout in a year or two.

    The V2 is and has been nothing short of amazing. There are issues/quirks that the platform in general has that I can attest to, that you will not find in any YouTube review.

    Excessive brake dust and noise

    Suspension/camber setup likes to eat front tires and feels like a truck locked in 4wd occasionally when doing sharp turns in tight spaces

    Limited slip diff causes driver side axle to feel like it's binding up when the fluid is cold and thick

    No Bluetooth audio streaming in the 09-11 cars? The hell!

    Black Raven is probably the weakest paint and nearly impossible to mask blemishes

    No HID fog lights and many exterior/interior lights are not LED

    Cadillac tax (see:corvette tax)


    There is more, but now I can talk about the positives. The car is smooth like a Caddy, but with the mag ride, a push of a button transforms it into a race ready beast that will outperform MANY cars out there in stock trim. My 5th gen had a bunch of suspension mods, but doesn't turn nearly as good as the V.

    The auto trans (6L90E) is a beast. Once it's in sport mode, the magic happens. It suddenly has firmer shifts and every gear is wound out longer in the RPM range. Also, 1st gear is activated but honestly, it's pretty useless even in stock form. You can shift manually or let it shift itself. When I was at the ocmd cruise, I found myself shifting manually only from a roll but letting it auto shift afterwards, which is complicated to explain. Guys making more power will overfill the trans to prevent parts from drying up under heavy load, which extends the life substantially.

    Best of all, the platform is solid. Guys are easily running 700-800rwhp with a stock converter, trans, and rear. No need to throw money at gears and shift kits, driveshafts, etc. The bottom end holds up very well even with miles. The tech and powertrain in this car is light years from anything I've driven for fun, previously. Most do not install headers as one of their first mods, because more power can be had for the money by investing in a pulley setup or even a cam. All American headers are well over $1000 on this platform.

    The only way I'll let this go would be for a V3.

    Anyway, more pics and vids coming as I have quite the project this winter

    451 is a great starting point though. How much boost was that at?

    Also, maybe I missed it but any plans to do gesrs with the 6 spd?

    Finally... dyno day should be a great day for u on the Dyno Jet this Easter!!!

    About 8-9psi. I didn't have them hook up the sensors, so I'm not 100% sure.

    The factory gearing is optimal for this platform.

    We discussed this a little before. I need to seriously fix the top coat before a ceramic coating is applied. I'm not sure if I can get it 100%. I've been watching CQuartz applications for a while and can do it myself, but I think I'll eventually have the car wrapped. Black Raven just sucks to maintain. Maybe the Meguiers treatment will whip it into shape and make me want to do a ceramic coating. Doubtful lol!

    I'm excited about the dyno day regardless of which vehicle makes it....or even if both make it. I'd like to see what the V does with the pulley and headers and then compare numbers with the Land & Sea dyno.

    BTW- I need to talk to you to see if "LTXTech" is interested in sponsoring a dyno day at that shop in Hamburg. Maybe a season ender dyno day or mid summer. Otherwise I might work with the owner and throw something together that's a little more low key.
