Engine for Z/28

Here are the numbers that I posted in a thread back in Jan. of 2012, all of my numbers come from GM documents (press releases, etc.) and not from magazine articles/suppositions. I think my numbers are right on track and show what we should expect from an Alpha Camaro:

"Given that the original numbers were taken from somewhere other than a GM press release, I went and located the official GM press release to verify some numbers.
"All three engines support the ATS’s agile and lightweight driving dynamics. With an estimated curb weight of less than 3,400 pounds (1,542 kg), it offers a more favorable power-to-weight ratio than key competitors. With the 3.6L V-6, for example, there is 1 horsepower for every 10.8 pounds of vehicle weight. That’s better than a 2012 Mercedes-Benz C350’s 11.9:1 ratio or the 2012 Audi A4 sedan’s 16.6:1 ratio."

Now if you plug in their 320 est. HP to their 10.8 lb per HP, you come up with 3,456 lb for the DOHC V6 ATS. Now plug in my numbers from earlier where there was 70 lb difference between V6 manual and SS manual (and they are currently talking about the DOHC V6 in the ATS with auto only, no manual which would make an even better number for us), then you arrive at 3,516 lb for a V8 version. And if that translated exactly to a 6th gen Camaro, we are still at 333 lb less than the current SS manual. Go read some of the press release about their weight reduction strategy, every part of the car was looked at for weight reduction, they concentrated on reducing weight by grams not pounds throughout the car, the made use of high strength steel and ultra high strength steel to allow parts to be thinner/lighter yet as strong or stronger. Almost all of this should move over to the 6th gen Camaro, I think the naysayers will see a difference if they look carefully at what GM has done with the ATS. These weight saving steps are a mere glimpse of GM's future production techniques."

The thread in it's entirety is here:

I think that at this point in time it is very clear that the 6th gen Camaro is going to easily be 300+ pounds lighter than the 5th gen version. All that being said, I too see no reason that there could not be a 5th gen Z/28 to pick up the slack until they get the 6th gen Camaros in production.

OK 300 lbs instead of 200. I'm not saying I'm not impressed with the weight reduction. My point is aimed at those calling the 5Gen a pig. If 200 or 300 pounds makes a car a pig or not is the question. Some say that a 5Gen Z28 is out of the question due to its weight, I'm not buying that. There is also the placement of weight, center of gravity, etc. To consider. While weight savings is great (very great) 300 lbs should not prevent a 5Gen Z28 from coming into existence.

As I said, I see no reason there could not be a 5th gen Z/28, so I'm in total agreement with you there. And lets be real here, the 5th gen is a pig when the ZL1 weighs over two tons!!

I know you're good with a 5Gen Z28.

A pig of a car is one that is not capable of providing enjoyable laps at a track. So even at its weight (which could be less) the ZL1 IMO is not a pig. The funny thing is many of those complaining the 5Gen is a pig put weight adding items on the car.

Imagine if you will the same ZL1 with 250lb off the nose of the car!

I've imagined it many many times (-100 plus lbs. off the nose).

So does the supercharger and heat exchanger really add that much weight?

I don't recall the exact weights, I think it would be at least the 100 lbs that 2nd Chance mentioned, my number is more oriented to the total weight difference between the SS and ZL1. Heat of the moment and all, you know.

Keeping things retro; a high reving small block would be on order.

I agree. Make mine an LS7, thank you.

I think many people that post don't realize that the LS7 is an SBC! And usually what they really meant was something closer to 5L displacement.

I agree. That is what prompted my answer.

Enough talking. Time to build it.
