Baseline pull in the CTS-V 509HP on 91 octane

Car has not been modified since I bought it 2 weeks ago:
AR Headers
2.55 Pulley
Upgraded Heat exchanger
Someone's tune on 91 octane - tune is locked so we can't access it.

Car will have the following installed this week:
ID1300 injectors
ZL1 lid
Kenne Bell Boost A Pump
Nitrous kit with progressive controller.

Looking for 600+ HP without nitrous and will be spraying a 100 shot at the throttle body.
 
Impressive! ... and sweet lookin' too!  If you have 509/465 now... do you plan to retune so you can build on what the dyno tells you after the mods?
 
I bought a used ecm and had it matched to my car by a gm tech that came to my house. Car will get a new tune from the shop its at. Doing a flex fuel sensor setup.

I forgot to mention, I"m doing the fuel mods so I can run E85. HUGE power gains on this platform for E85. Usually 80-100HP.
We'll see soon enough!
 
I'll be very interested to see the gain with E85... and what has to be done to the fuel system/tune.

Factory the V has dual in tank fuel pumps with a fuel computer, you feed it with 15volts (no more) to get an increase out of the pumps.
Install new injectors and you're done, just need a tune.
Recently it was found you could buy the GM Flex fuel sensor and put in a new wire in the PCM that was previously vacant to allow for automatic flex fuel adjustments. You can turn on full flex fuel adjustments from E0 to E100 with a custom timing table that is enabled via HP Tuners. Super cool as I can fill up with E85 then if I can't find it just top off with E10 91 octane and the timing will adjust appropriately. All of this was figured out in the last 6 months so perfect time for me.
600HP on drag radials is good for 10 second passes for most people, we'll see if it works for me. The nitrous will just be a guarantee, some guys with a 100 shot on top of 600HP are trapping over 135 in the 1/4 mile!!!
:)
 
Unbelievably simple sounding.
That's the way to have it... your way (no matter what happens).  Don'tcha just love it when their engineers help you out like that!
 
I just want to see 600+ UWHP (USABLE WHP), Mike!  That's where you left off with the Flex :)  After that, 1000 UWHP!!!

Drag radials make things pretty decent, I'll find out in Jan. :)
I also have my M&H drag radials from the Flex 275/50/R17 that will fit, just need to buy some Weld wheels (only ones that will fit) in 17x10's for it, bad thing is they're $1K a pair for the rears :(
 
Your fuel system is the best one GM offers.  It has more capacity than ZL-1.  As I'm sure you've checked, your friends at Squash can help you gain more if needed.Another great source is Greg at Pace Performance.  He personally has a GXP stick with a 2300 Magnacharger and lots of fuel mods etc. Very well versed in this GM supercharged CTS-V (and other GM vehicles with stock SC). From what I understand it is basically a 1900, with rear air inlet.

Isn't it nice how much easier it is to switch ECM's in GM cars!  Are you going to ask original owner about who tuned vehicle?  Would be worth it to have 2 ECM's.  That way, you could have 2 tunes ready, if you decide to run E-10, or have to.  I am able to switch out ECM's in my G8's in a minute.

Does it have a custom CAI?

As for wheels, how about a wheel spacer that moves the wheel out an inch or whatever you need to clear rear brakes?  You can even get them with changed bolt patterns so you could run Ford bolt pattern on your 120 mm pattern Caddy.  Smaller diameter tire like the 17's you had may not have clearance issues with fender, especially if you can firm up rear so it squats less.  I run 17x9.5" Borbets on my 09'G8 with 275 Hoosier DR's.  They are 48 offset (120-63 mm).  Son gave wheels to me.... came off his Firebird T/A.  He has 2 left. Of course I don't have Brembo Calipers.

I have an Airaid CAI (was on the car) which is supposed to be one of the best.
I've already bought a new ECM and had it changed to stock, no idea who original owner is and not worried about it, cost me $99 for the used ECM and $125 for a GM tech to come to my house and program it to stock.

I'll take a look at the wheel spacer as an option, to see if it can be done.
 
Like I said in my e-mail, since the 10" x 17" Weld wheels are 48 offset, the wheel issue for other 17" wheels has to be the thickness and design of the rim that is rubbing on the end of the caliper, not any part of the inside face of the wheel rubbing on the outside face of the Brembo's.

 
Well for the last 4 years it's weld or borbet drag wheels. I put my 17x8 wheel from the flex and it might fit with the right adapter but will the adapter be ok with 600tq...
