[cobra 23]

if a new supercharged z28 is made, how much do you think it will weigh?

Who knows.... Its all guessing right now!

im thinking about 4200 with the supercharger, intercooler, and heat exchanger.

Who knows???? We dont know anything about it....

Perhaps the question could be, "What do you think it needs to weigh to deliver the performance of the past in today's world?"

If that is the question, would the target not be about 3,500 pounds?

REcently a magazine stated that it would be 200-300 lbs lighter than the CTS-V. The CTS weighs almost 4300.

I'll opt out of the intercooler and heat exchanger if mine has a supercharger...

I was told the workbench for ordering will open in may 2010 by the fleet sales at the dealership I use, I'll be there for a Z28 first, vert second choice. Either way I'm getting a top of the line, loaded and hopefully under 10k VIN of every year in this generation.

Just curious, what do you think about the past would even come close to today's SS?

Todays SS makes 426 HP SAE Net. This is, and someone correct me if I'm wrong, approaching 500 HP gross as reported back in the 60s (which what I think you are saying). The IRS, the Brembo brakes, 6 speed transmissions are all things in the today's world that even a COPO couldn't touch. And that doesn't even come close the weakest link in the old cars..........tires.

This is a great discussion, it's like comparing athletes from different eras as to who is better, but the only thing I see in the older cars is a bit lower mass and that is made up for with the structure and safety hardware required in the modern era.

Seriously, I would like to hear what in old cars a modern Z28 would need to do/be.

Don't get me wrong, I LOVE the old cars. They just don't hold a candle to todays car other than the mystique that's great to talk about.

I was not clear in my post and, up front, I agree with you that the cars of the past, while special, are not the match for modern ones.

What I was addressing with the weight had to do with my sense that the original Z/28 was a great road course car and for that to be true today, we have to fight the weight monster. It is the reason I went with a Shelby GT (the one he builds at his plant in Las Vegas) rather than a GT500. Too much front end weight with the 5.4 motor.

Today's cars make more horse power in factory trim than we could have ever imagined in the 60's. The SS makes plenty I agree.

In my perfect world, there would be a Z/28 that was small block powered, supercharged, and weighed 3,250 pounds. Maybe that is my fantasy world, huh?

This is actually a VERY big topic right now, i think the Camaro's biggest obstacle is the same as the Challenger's except GM has overcome it better, that would be having a 2-door car on a 4-door platform, you're just wasting weight in that scenario. As far as the engine goes expect an extra 150-200 pounds if its supercharged, another reason im not a big fan of supercharging the Z/28, id rather see a cammed LS7 putting near 600hp with less weight and a meaner roar If people want a good comparison of what the Z/28 would be like supercharged then look at the GT vs the GT500, the GT is like 3500lbs while the GT500 is around 3850lbs? Hopefully GM will see this as a problem and take measures to overcome it, im hoping for lots of parts swapped for lighter parts, lots of emphasis on weight savings in the new Z, otherwise you might as well just supercharge your SS right?

The LS7 is done. GM isn't going to be putting it anything else.

Yeah yeah ive had to hear that everywhere i go, LOL

i still believe if the demand was good enough GM would put the effort into bringing it into a new generation for the Z/28, i just preffer it because its lighter than either the LSA or LS9, and with a simple cam swap can put out 580+ horsepower (as seen in the LS7 SEMA Camaro). Other than that im just a fan of N/A engines, haha, that parts more personal based than factual based

why? those things allow more boost. without an intercoler and heat exchanger 6lbs is prob max. not to mention compression will have to be lowered. then itll have less hp than a gt500. but still more weight?

[Mr. Wyndham]

The CTS-V weighs about 4200 lbs. May I ask if anybody would not buy one of those (assuming you had 60 grand to spend) just because it was heavy?

Motortrend seems confident that an LSA-equipped Camaro will come in some 200-300 lbs less than that. We shall see....

Having said that...weight is 90% perception, imo. Look at some of the highest-regarded "supercars", and only a few of them would be considered feather weights, and nearly all of them will cost your first-born AND $100,000 dollars. With the right suspension, and adequate power, you can overcome the weight imposed by safety standards, and structural rigidity.
