2012 CTS-V 630HP Upgrade Kit - DYNO TEST

[JSE]

Hello - I have a 2012 CTS-V Sedan . . . automatic.

I had the Lingenfelter 630HP upgrade kit (pulley, intake, thermostat, filter) installed with the ECU tuning software . . . I was wondering if anyone who has installed it can tell me what their's does on the Dyno. Mine Dyno'd at 505 HP and 505 Torque - which seemed low to me . . . but the shop I was at contends that their Dyno reads about 20-30 HP lower than most.

Thanks!

That does seem very low. We saw 477hp and 501lb/ft at wheels on a stock ZL1. 492/513.6 with a canned tune. Your horsepower should be about 50 higher then that. Have you done any data logging? I'm wondering if you might be getting some knock retard. I was getting a fair amount until we tuned it out.

I'll be dynoing mine in a couple of weeks, but its not gonna show anything related to yours. I have the equivalent to LPEs 650hp package (9.55" crank pulley, 95# injectors), with a better intake, better heat exchanger and CMR tune.

I just had my 2011 CTS-V manual done here in Denver. It Dyno'd at 557 RWHP and 556 Torque. I would think the altitude may take some of the power away? It seems like something is wrong with either your tune or their Dyno. I had Lingenfelter send the ECU with their base tune here but was causing some crazy spark nock and needed to be retuned here. Crazzy fast now!

My 2012 CTS-V (automatic) is at the dyno now, & I am hoping for 525-550 RWHP (corrected) with the LPE 630 HP kit. It made 474 RWHP, stock. Good luck.

So what did the Dyno show today? Thanks.

Hope to pick it up early next week, & will post results at that time.

473 RWHP & 474 RWTQ "Before", and 531 RWHP & 545 RWTQ "After". Lingenfelter 630 HP Kit, nothing else, installed by Futral Motorsports, Walker, LA. It was & still is a BEAST...LOL. Only in America...

Does anyone know what Bosst level the 2012 Caddy CTS-V makes "stock", & then "after" the above described changes to the Pulley, K&N, PCM, etc.? See the Before & After HP & Trq #s above also. Thanks for sharing.

8.5psi stock. Should be around 12 with a 2.55 upper, 13.5 with a 9.55 lower and stock upper (650hp kit).

[fofo]

Thanks. My 650 HP kit was installed by Futral Motorsports, purchased from Lingenfelter, & the stock Boost gauge is "pegged" at 15# when I stand on it. This was kinda surprising to me, especially after I see your quote of 13.5# with a 9.55 lower & stock upper. Maybe the calibration is off a tad on the Boost gauge, or maybe it indeed is making slightly more Boost than expected. Iwas very pleased with the "after" # I quoted above from the dyno session.

Thanks again!
