    '12 LSA making some power

    I'm reading more and more how the '12 LSA is putting down some power. I think some of the changes made for the ZL1 trickled over to the V unpublished.

    Good article:

    Wow, very interesting. It's also in Opulent Blue, which I want to trade my 2009 sedan in for.

    Re: '12 LSA making some power

    I have a brand new 2012 auto wagon - wouldn't mind putting it on the dyno to see if this was a one-off factory special or if the 2012's really ARE putting more power to the wheels. Anyone here in the Houston area want to offer up their dyno for a quick test?

    I had heard that the 2012 V's had 580 hp.I cannot remember were I heard it. I remember them saying that cadillac was keeping it under wraps and 2012 owners were the testing arena....They wanted it to contend with the new M5.. A friend drove my 2012 auto- vagon and he said WOW!!. He has an 09 coupe manual. very interesting to say the least. Anybody have dyno numbers on a stock 2012 ??? let us know.

    bbang - if you've got a 2012 wagon as well, maybe we can get both of ours on a dyno soon and post the results. I would say if BOTH of our cars test out as well as the one that started this thread, then maybe we are onto something. If I can find someone to dyno mine here in Houston I'll do it and share the data, but I don't know if it's worth me shelling out cash just to find out - I'll do that when it's time for my first round of mods in a few months. But I sure would like to know now.

    I thought the ZL1 was getting it's extra power from an updated intake and a few other bits - it looks like our 2012's are identical to previous years, so where's the extra power coming from?

    Re: '12 LSA making some power

    ...and I thought several places have already dyno'd a 2012 CTS-V. I saw a wagon tested that was by Insideline that did 492hp and 502 tq at the wheels (manual). Still, that would indicate that the engine is making more than 556 hp. If you use the standard 15% powertrain loss (which of course is an estimate) then 492 at the wheels comes out to 578 at the crank - pretty close to the claimed 580 of the ZL1.

    I guess I have to get mine checked out - would love to know what kind of baseline I am working from.

    It mainly comes from the ZL1 having electric assisted steering. No power steering pump to rob the power.

    My blue 2012 feels slower stock then my 09 did. Haven't put it on a dyno yet, I highly doubt I will until its pretty heavily modded.

    Re: '12 LSA making some power

    I have an '11 V Coupe with auto trans (built 2/11) and mine put down 470 RWHP (Dynojet) bone stock with 400 miles on the engine. I am sure it puts down way more with the W4M full cold air intake, Borla catback exhaust and W4M tune now that I have over 14K miles. GM has always under-rated their vehicles.

    How many miles were on the engine when you had it dyno tested? Was it on a Dynojet?

    Yeah that's what I was wondering too. The type of dyno makes a HUGE difference since some read much, much higher than others. 490 on a dynojet could easily be 450 on a mustang dyno.

    Re: '12 LSA making some power

    Not all brands of dynos, and even the same brand of dynos, report similar horsepower and torque ratings. For the same car, some dynos report higher numbers than others and vice versa.

    The April GM High Tech Magazine Dynojet 224X test of a 2012 CTS-V waggon reported rear wheel power output of 525 HP / 521 Lb Ft Tq, very high numbers for advertised crank power output of 556 HP / 551 Lb Ft Tq.

    The May GM High Tech Magazine Dynojet 224X test of a 2012 Corvette LS3 Grand Sport reported rear wheel power output of 415 HP / 409 Lb Ft Tq, also very high numbers for advertised crank power output of 436 HP / 428 Lb Ft Tq.

    Therefore, the high rear wheel power output reported by the April GM High Tech Magazine Dynojet 224X test for the 2012 CTS-V waggon does not, in and of themselves, provide sufficient evidence of an increase in power output for 2012 CTS-V LSA engines.

    Regarding the higher 580 HP / 556 Lb Ft Tq crank power output of 2012 Camaro ZL1 LSA engines, the May GM High Tech Magazine article on that car describes a number of power enhancing differences not found in CTS-V LSA engines.

    In light of the power output war now being waged by BMW with their 2012 M5 and Mercedes with their 2012 E63 AMG, it is highly unlikely that Cadillac would choose to remain silent about any power output increase for their 2012 CTS-V.
