Okay, I don't know really that. But now that I have your attention;

I bet the Z will be increased to 550 HP for 2010.

Hear out my logic and follow my numbers....

I know, I know...GM now certifies their HP ratings. But you are dead wrong if you think that GM doesn't tweak the HP using their own tests and instruments to get it into the desired range before the official tests.

Lets look at a previous HP comparsion between the C5 Coupe/Convertible and the C5 Z06.

2002 to 2004 Coupe/Convertible = 350 HP; the 02 -04 Z06 = 405 HP

So the C5 Coupe/Convertible made 86.4% of the HP of the Z06.

Fast forward to the C6. GM stated that new new C6 Z would have a greater % inc. in HP over the base C6 and sure enough it did.

LS2 Cars made 400 HP while the LS7 makes 505 HP. So the LS2's made 79.2% of the power of the LS7 Z's.

However, the LS3 debuted and it was certified with the bi-mode exhaust at 436 HP. Why not more? Well b/c at 436 HP the LS3 made 86.3% of the HP of the LS7 Z, just about right on the dot that the C5 LS1 made compared to the LS6.

Now let's go father and use some of this logic...lol

The LS7 at 505 HP makes 79.1% of the HP of the new LS9 638 HP ZR1!!! Yep, almost the exact same % the LS2 made compared to the LS7! Sooooo....GM who obviously loves the numbers 79% and 86% may just bump up the LS7 Z to 86.4% of the HP of the new ZR1 which would equal 550 HP!

CORVETTE!

We'll see if this is in the big announcement from GM tomorrow.

Hope your right. It was mentioned that there where going to be upgrades to the 2010 models

ATC399

...Lets hope they dont drop the Z/Vette...I know the sky is NOT falling

PureSwank

Sounds legit...I just dont like that fact that 2 years from now a gain of what 45hp increase on an engine.......really really sad!!. If thats the case then let me just ad a cam to my 07 z06 and have it kill the brand new z06, and lord know how much its goign to cost then. What chevrolet should do Is really bust out with a 600hp+ Z06 stock for the 2010. Or just end the damn thing every year a new car comes out with 50 brand new horsepower addition to the previous one eeewhhhh!! Man just make a car with 700hp and end it!!!!! that way you'll be ahead of the game for 5 incoming years!!!. If I was chevrolet you know what...Id make a 800hp corvette and relax for then next 7 years from competition. They keep making new ones with weaker horsepower!! lol

MyBeaches

I remember these same threads for the 2008 model, and then the 2009 model. Glad those threads were right.

NEVERL8

If the Z gets 550 HP I will be at the dealer tomorrow putting in my order. Now all Katech has to do is make a decent set of gears for the Z and I would be at their place the day after with my down payment.

Also, I think the forum is full of enough garbage that we don't need to be posting untrue announcements in the subject of the post to get people to click on it. Before you know it that will be all over the internet because somebody "saw it on Corvette Forums".

Katech_Zach

RPM already has them. When are you dropping your car off?

Halltech

Something tells me that Jason already knows the answer to this question.

Don't mean to be the voice that 'rains on the parade', but I don't see GM spending the EPA certification money on more hp for the Z06. Also, if the increase brought an increase in fuel averages, how much? Enough to tip the Z06 into a gas guzzler tax?

It would make sense to offer the different sized ZR 1 half-shafts to reduce wheel-hop. No certification problems and a reduction in a warranty causing problem. Also cuts down on maintaining different parts in the inventory. If it happens good for us, but I think the horsepower race is very close to being over and the ZR 1 may have been the last hurrah.

I highly doubt it....

With GM in the situation they are - I don't think adding 45HP to a 500HP+ car is at the top of the list of "Things to Do"

Not being negative - I'd love 550 from the factory, but just being realistic.

NytmereZ

Your logic is more wishful thinking than anything, I do see the Z06 getting up to 20 more HP in 2010, no way in hell it gets 45 more. Gm isn't going to spend the money to get 45hp more, they will do minor things like they did to the 2002 for marketing purposes, the 2002 wasn't any quicker than the 01. If GM gave the Z06 45 more hp, it would be way to close(actually probably even) with the ZR1 in most acceleration tests, they would be shooting themselves in the foot. As of right now the Z has more than the rated 505, Ive had plenty of High horse cars, there is definitely more horse than 505 in my 06, and it is stock (for the moment)

My guess is that they could add about 25 hp to the Z06 with Direct Injection AND increase fuel mileage slightly.

Halltech

My guess is Flex Fuel. E85 compatible, which on its own, will not increase HP.

If GM wanted to do it right, they should bump the static compression ratio to 12.5:1 and run VVT and FlexFuel. This may be too much CR when running E10, which is 93 Octane out here, but a separate timing table could be integrated for E10 use, with slightly lower timing.

I run 5 to 7 degrees more timing on my E85 Escalade and get 16-18 mpg on the hwy vs. 14 to 15 with stock timing.

Then E85 would, with its native 105 Octane, coupled with 12.5:1 CR, net another 20 to 25 HP. Tuners could safely bump timing to bring another 5 to 10 HP to the table, without messing with the air fuel ratio of 9.8:1 when running E85.

DOD, would also add to fuel mileage on the road without sacrificing power.

One more thing. I compared my E85 Flexfuel Escalade to the Corvette C6 LS3 ECM and all the E80 tables (Open Loop PE) and stoich tables (there for some time now) are identical. I suspect, but would not recommend, that the LS3 and LS9 could run E85 now, with the necessary fuel pump change (not sure about this) and injector sizing. My best guess is that the fuel pump could handle E85 with larger injectors, but I could be wrong.

vray

If they announce a HP bump for 2010, who is going to buy the glut of 2009/2008 inventory? Dealers will have to give the suckers away! Oh wait, the already are!

jschindler

There is just this one little fly in the ointment - E85 is harder to find than a priest in a strip joint. This is just one more way the government has actually subsidized the large SUV market. There are hundreds of thousands of Tahoes and Suburbans on the road that are credited with getting 40 mpg for CAFE purposes because they are E85 compatible - even though probably not a single owner of one has ever run E85 in theirs.

I heard GM will announce a few things tomorrow, some good news some not. But the big announcement will be the takeover of Chrysler.


Our national obsession for getting things on the cheap – the “Wal-Mart” syndrome - isn’t helping, either. We have become a nation of bargain hunters, consumer zombies addicted to deals that feed into our instant gratification and “right now” mindset. Unfortunately that mindset is helping destroy our country from within by contributing to the decline of our manufacturing sector. And this is having a devastating effect on our long-term strategic future too.Let me get back to the issues facing the domestic automobile industry, one of the pillars of our manufacturing base in this country. The threat to the “Detroit 3” has far-reaching implications for all of us. One in 14 jobs is either directly or indirectly connected to the domestic automobile industry. Repeat that figure to yourself because it’s daunting. We’re not just talking about the threat to one of America’s core industries here, and it’s not just Michigan or the other scarred “flyover states” that will be devastated by this either, because there are automotive suppliers and dealerships big and small all across the country that would be immediately affected if Detroit is allowed to go bankrupt. And for a nation teetering on a deep recession, I don’t need to tell you that a bankrupt Detroit could send this nation over the edge – and right off a cliff.Spare me the free-market proselytizing and the collegiate level economic theorizing that is popular with so many whenever this is mentioned, because there’s no time for that anymore. The debate about whether or not Detroit needs financial help? That ship has sailed. We’ve gone way past the point of no return at this juncture because Detroit is just months away from catastrophe. Now it’s only a question of how much money and how soon it can get here. I’m sure you and your advisors are well aware of the urgency at this point.Mr. Obama, you come to be the 44th President of the United States at the most pivotal time in our nation’s history. Not since the calamity of the Great Depression or the harrowing threat to our democracy in World War II has this nation been on the brink of unfathomable disaster. The posturing, stump speeches and pat speeches that went over so well on the campaign trail count for exactly zero right now. We all know the difference between campaign rhetoric and substantive analysis, discussion and decision making, so at this point we’re not really interested in hearing one more word.Instead we want rolled-up sleeves, clear thinking and a clean sheet of paper. We want the Best and the Brightest that this country can muster, and we want those individuals to attack our problems with a zeal that we haven’t seen in Washington in at least 40 years.We need action, Mr. Obama, because for too long we’ve seen inaction, excuses and a general shirking of responsibility and accountability at every turn in Washington. But most of all, sir, we need hope. Hope that our representatives will have the strength, the courage and the vision to step up and deliver the kind of leadership that this nation so desperately needs. Hope that our nation is not on the precipice of a cataclysmic decline but instead is on the verge of a great new era of innovation, creativity and global leadership.And finally, hope that you can make a difference. Hope that you can get this country back on track. And hope that there’s somehow and some way that you can bring us all together again. We’re counting on you, Mr. Obama. Thank you for listening.

Yeah, I actually thought about that long after I posted but I left and headed out to an ice hockey game. I promise not to do that again, however there will be many more on here AS ALWAYS that will keep up with the BS.

but I do 100% believe the Z will have a bump in HP next year. And I do believe it will be close to or dead on 550 HP.

CORVETTE!

The LS7 is already at its limit based on the emissions, noise and durability requirements, so a HP increase isn't going to happen. Besides, they already have a new halo car with more HP in case you haven't heard...
