Hi all, this is going to be my first post here and I’m pretty excited about it.

I have an Auto 2012 CTS-V Coupe. It has a few mods already but I’m trying to see what it would take to install some more.

What’s installed:

1. GP performance stage 2.5 cam
2. Double valve springs,
3. Chromoly pushrods,
4. Trunion bearing fix kit
5. New high pressure high volume oil pump
6. Long tube headers, no cats with full 3” exhaust all the way into the stock muffler. The electric cutouts are right in front of the muffler so when they are open it’s straight piped.
7. Transmission replaced about 5000 miles ago, installed a one piece upgraded aluminum drive shaft at the same time.
8. Porcelain tip spark plug wires to keep the headers from burning them acolder spark plugs for more power
9. Varimax heat exchanger coolant pump
   
   What I have that is not installed yet:
10. 2.55 supercharger pulley with a new belt in a box.
    I will need bigger injectors before it can go in.
    Should I invest in anything else? Like a new supercharger isolator coupler? Also how much power can the auto Trans handle? Should I get a trans cooler before the pulley goes in?
11. I’m not exactly sure how much power I’m making currently, I would assume somewhere a little south of 600 hp but I could be wrong. With the pulley installed it should be making around 650 hp maybe, but correct me if I’m wrong.
