2012 Z28 HP Speculation
 
After reading all about a pulley change and other minor mods on the LSA to get 620 HP for under $3K, I'm wondering if the Z28 LSA will be rated at 556 HP like the Caddy or if GM is going to up the anty. They could easily push the Z28 to 600 HP without much problem. What do you think the rating will be for the LSA in the Z28?

I really need to take my vote back and put it on the last one.

although I feel the lsa will be under the hood, I think it's too early to claim it as fact.

If it is the LSA it will be more then 556 hp. mainly do to my belief of better intake and exhaust flow like on the v-6.

PeeBee 12-27-2010 09:02 AM

It simply needs more than 556hp.

750-ish would be more like it :)

Shurenuff 12-27-2010 09:15 AM

I'm going to guess 575-ish

:facepalm:

I can't order one yet, and you're already making me think about modding it? :laugh:

it's not fact yet. just because an eng cover says LSA doesn't mean jack. it's not a fact until an official press release.

I've got my fingers crossed for an LSA/LS9 hybrid with forged slugs, etc. While the LSA can definitely compete with the GT500 powerplant stock, it doesn't have near the ability to modded to high HP levels like the overbuilt GT500 engine.

That's one area that Ford definitely has the upper hand if the Z/28 comes with an LSA.

Its as close to a fact as can be, some ppl know more then you think.

and if you know something and are coming out with it. . .putting someones job at jeopardy is never a good thing. in essence that is what you could be doing by saying you know it as fact.

either way it's still not fact until they come out with a z28 and the information about what's under the hood. Things change. up until it's confirmed from the horses mouth it isn't fact.

2SSRS@Gen5diy 12-27-2010 11:15 AM

Non of my info comes from GM employees or GM vendors. But more a common sense, Doing my woke to see what is going on and why, It dos not make any sense to release a new motor in the camaro, AKA gen V motor, and the LS9 will bring the cast to $60k+ on the car so if we all angry that its a supercharged V-8 then what is left to not be a fact.

Next there is timing we all know that a car has a life span for the Wow affect, so 2 years after the release of the gen5 camaro its time for the convertible to come out and now it will be about 1 tear till the Z28 comes out and that will keep the line fresh in the mind of ppl and then there will be some thing new after that like a new ........ and so on.

That is how all car company's work and all manufacturing company's work.

KarFan 12-27-2010 11:31 AM

Speculation on speculation. The LSA is the best bet as it's the only engine in GM performance lineup that is more powerful than the LS3 but not premium priced like LS7 and LS9. So it could be used on a vehicle priced near the main competiton; GT500.

In any event IF the LSA was put into the Camaro I'd expect actual HP to be a bit higher than the level found in the CTS-V. CTS-V exhaust is toned down becuase it's a Caddy.
However even at 556 HP it trumps the GT500's advertised power already and GM Marketing may choose to leave that figure alone. All speculation at this point.

KKreme15 12-27-2010 11:55 AM

580

It's all just speculation. you stated it as fact, and that's just miss information right now. until it's from the horses mouth it isn't fact.
Again things do change. What doesn't make sense to you might make sense to someone behind the curtain. we don't have the whole picture. Maybe just maybe some peoples speculation is right it will be the lower end of the LS9 with the top end of the LSA. . .it's still speculation. They were developing the LS8 for a while. maybe with the rebirth of the z28 they will introduce the ls8. but the last official information about the ls8 was it was scraped. but you just never know until that press release is official. that's all I'm getting at.

FINALLYSATISFIED 12-27-2010 12:30 PM

576hp, :)

midnighter 12-27-2010 01:17 PM

490hp to the rear wheels or something

OldJedi 12-27-2010 04:04 PM

My best guess based on no specific facts is that it will come in around 585HP with some variation of the LSA using the 2300 S/C instead of the 1900. Like I said this is strictly a guess and a wish on my part. Until the New York show in April, we might not know for sure. So step up and place your bets and lets see who comes in the closest to the actual horsepower.

truth411 12-27-2010 05:03 PM

Hopefully about 600hp.

Supercamaro64 12-27-2010 05:13 PM

my hope is around 600, my guess is probably around 580

You never know but the ls8 is dead, long live the LSA.

Dang Straight Shurenuff.

Our beastie will be heavier than the pony and needs the HP to compensate. I think 600 HP is a jaw-dropping number for most folks, so I'm going there. It has the "Holy crap, I want that" factor.

I just hope they managed to attain this given the innumerable variables, along with some outstanding handling characteristics.

derklug 12-27-2010 11:19 PM

595 to get 1/4 mile better than a GT500. Road course performance will depend on price point.

DGthe3 12-28-2010 12:55 PM

I went with #4. I expect the power to be above the CTS-V's 556, somewhere between 570 and 600. But I'm not willing to say definitively that it will be the LSA. It probably will be, but there is a reasonable chance that it won't.

I can switch your vote for you, I assume you picked choice #3?

That's one area that Ford definitely has the upper hand if the Z/28 comes with an LSA.

If there is a hybrid between the LSA and and LS9 I'd put my money on it going the other way. LSA on the inside, with a 2.3L blower.

Isn't the CTS-V essentially on par with the GT500 (or at most, a little behind), with 556 hp and ~4400 lbs? As for road course performance, I have no doubts to the Z28's superiority. There is a lot of potential thats untaped in the SS, and I doubt that was accidental.

tweeter81 12-28-2010 01:08 PM

GM is NOT going to give the new Z/28 more substantially power than the CTS-V for $12,000 less. It's just not going to happen.

People need to use the brains God gave them and look into past performance cars to find the answer to this question. The new engine is most likely going to be the LSA, and it will only make more power than the 556 HP the CTS-V has, if the intake and exhaust are slightly more free-flowing. I would guess a 10 HP bump to approximately 566 HP.

GM has absolutely no reason to push the limits of the motor more than they already have (and for less money, even).

This new Z/28 doesn't need 600 or 800 HP to be competitive and beat the GT500 performance numbers. It just needs high quality, wide, and sticky tires (read: not Goodyear F1s) and a great suspension setup for the roadcourse.
