The supercharged one would be easier to improve performance upon with a simple pulley swap.

Improve performance? We're talking about FIVE HUNDRED FREAKIN' HORSEPOWER!


The extra weight, cost, complexity and mass is simply not worth it to me, personally.

I'll highlight the important part...
Fortunately, timing is on the auto maker’s side. The recent introduction of the ’08 Corvette’s 430-hp LS3 V-8, along with the release later this year of the ’08 Chevrolet Tahoe Hybrid’s 6.0L V-8, represent the last editions of the Gen IV engine family, Stephens says.

All subsequent introductions will be of the Gen V architecture and could have DIG fueling integrated from the ground up, especially considering the refinement of the current test engine’s operation. The greater specific output provided by DIG also would allow for greater engine downsizing, thereby improving fuel economy even further
All future engines will be Gen V according to Tom Stephens, group vice president-GM Powertrain and Quality.

Now, how many of you would change your votes?

You've never owned a modern supercharged vehicle have you? I was in your shoes until I did. Those things you fear are insignificant. The extra weight is minimal. The cost? Possibly a little more, initially. However as most of us modify our vehicles, the amount of extra paid for performance improvements will be lower for the Camaro that comes from the factory with a supercharger. Complexity? No more than the factory N/A Camaro. Mass? Seriously? It aint as much as you are scaring everyone into thinking it is.

Face it Charlie... you must give in to the darkside... embrace your fear.... otherwise, your next "dream" Camaro may be an SS, not a Z/28.

This is pointless in a way....

GM has a target HP mark they want/need to meet. If they can meet it N/A, they'll do it. If they need a power adder to get there, they'll use it.

Simplier is better for everyone. Its easier and cheaper to assemble a N/A engine too.

I remember that...but the "timing" aspect was speculation, on the authors part.

Remember that contract thing between GM and the UAW? the very few Gen V items were all set for 2011, granted, they were truck engines, but still...and we all know Camaro will be built in '08/'09....so

I'm not holding my breath on generation V architecture, for that reason only. I hope I'm wrong.

How about we ask it like this; "Would you rather have an expensive, thirstier, less driveable 500hp 6.2 or a effiecient, driveable, gas friendly 500 hp 6.2 that you could up to 700 hp at a whim?

Wasn't there a turbo f-body a couple of times? At least once for sure.

Because people fear what they don't understand.

I don't know maybe it's the gearhead in me but I would get complacent with 800 hp after a while.

A whole screw type supercharger assy. (blower, aftercooler, plumbing, fluids, etc.) isn't going to weigh more than a 100 lbs. Coming from someone who has completely removed the S/C assy. from several of our Ford counterparts as well as seen and felt the gains associated with just a pulley swap I would have no problems whatsoever in choosing an FI car over a N/A setup.

Exactly.

Turbo Firebird / Trans Ams. Twice. Never a Camaro. Never a supercharger.

Holy crap.... and you don't see a problem with that?

Not true.

I've put 100,000 miles on a supercharged vehicle I bought new, a Corrado G60. I've also driven many SC'd W-cars, blown Cobalts and Ions, MN12 T-Birds and Cougars, an SN95 Cobra, probably more I can't think of.

My take away was, there's nothing like a sharply tuned, normally aspirated, engine. Sure, if a blower is the only way to get that power - that's one thing. If you can get the same power out of a normally aspirated engine efficiently - that's a whole different story.

100lbs on the front end...bad.
So these SC 6.2 motors will be Gen V's? So I ask again, what will make the Gen V's different then the Gen IV's? Will we see NEW displacements? They say they can downsize displacement now that they can attain much more power out of what they have. So will we see the 5.3's stroke added to the 6.0 adn 6.2's engine block? 5.4 and 5.6 liters of displacement, 2 new engines to be work horses in the GM line up, and will be able to use the L92 cyl head design as well as the addition of DI.

Al, I think I answered you in the other thread.

Displacement: 5.X and 6.2

Heads: completely different than what we have now. Forget the L92 heads.

And LOTS more technological enhancements beyond just the addition of GDI.

As far as these blown motors being Gen IV or V. I don't know, I think not Gen V, I'm working on it though.

You could say that about a great many threads here, but we still talk/debate.

I'll take the N/A motor, please, for many of the reasons mentioned above.

And I certainly have had high-HP forced induction cars (2004 KB Cobra and an 88 Twin Turbo 5.0 Coupe).

But of course, to each their own.

Well, if the Camaro is going to come packaged with a direct injection engine, I'd say make the Z/28 a real high revving screamer. low 5.X liter displacement, 7000+ RPM, 400 horse, the best handling package, naturally aspirated. Crazy 500 horsepower handbuilt engines are nice, but the Z/28 should remain an accessible muscle car like it was for the last generation....with some crazy screamer built in to honor the old ones.

And I think the SS should be more powerful but also less focused on overall balance. Let it be the drag car while the Z/28 cleans up on the M3's and G37's.

I like the sounds of this.
