Do the. S'S and Z/28 have the same rearend? How do you know the rear end is safe, do you have test results?

Those who drag do not use the Launch Control. They just turn TC off and launch by feel. It's faster. And damage is avoided by operator skill.

LC is the main source of broken parts. Let's hope the Z/28 does not have LC. If it does experienced drivers will avoid it.

The point is the LS7 is not a HP monster and the stiff sidewall tires are likely to be loose. The "sticky" 1LE and ZL1 Goodyear F1s do not hold as well as the SS Pirellis. So I do not think Z/28 will not be any worse off than a bolt-on SS with regards to breakage. SS axles and gears have broken, but it is not common.

Understood, for sure...I never use it either at the drags...lol...But the factory does...It's a part of the design....Just sayin', I know anything can be drag raced. If the Z/28 has Launch Control to "help" you drag race better, I would think it's not strictly Verboten to drag race it.

BTW, Launch Control can be useful for standing-start auto-X, a motorsports forum the Z/28 should be rather well-suited for...

The “Little Hoss” Z/28 after it was repainted to jive with the Harrell race car color scheme.

A couple of Z/28s for your enjoyment...

...since the Z/28 is a dedicated road course car, I would surmise that LC is not part of the electronics. If they did include it, it would water down the product in my mind.

LC, & no-lift shift is all part of the PTM suite...which the car does have...

It is unlikely they would take out a feature that costs nothing to include (software), and weighs nothing (). Would it be engineered as anally-specific as the ZL1 was? Probably not...thinking along the lines of a 1LE or SS's version, instead.

But I could be wrong...just seems to make sense to me to put as many performance goodies into your "go-fast" Camaro as you can...

...and that makes sense, since it's an integral feature previously used. And GM does have the habit to use across the line features in new adaptations without change. Until they break ground with something new.

I had no idea what WORD means in cyberspace, sorry. I saw that it is connected to the smilie. I've seen the smilie version in posts that seemed to mean "in agreement", but the smilie holding the sign sure doesn't look agreeable... so I never did figure that out and didn't care. Not knowing this and reading what you posted made it appear to me that you were jumping off the cliff on me, which isn't the case and didn't seem like you. No disrespect here lowdown. At least I now know what it means.

Some different hardware. But do you think Chevy will build the Z/28 to be less beefy than the every day SS? I would hope not. So if it is at least as sturdy as the SS drag racing will be no problem at all. The Z/28 is no more powerful than a lightly cammed bolt-on SS.

if you look at the SS, ZL1, and Z28 rear ends, they are all different. Why would they use a different rearend from the zl1 to the z28 if there wasn't a reason, the zl1 is bombproof, the z28 is not and designed for the track, the zl1 for both. I would imagine they might try to save weight there, strong enough for tracking but not hard launches on a strip.

Speaking of drag racing Z/28s, I'd be remiss if I didn't share THE most famous one, ably wheeled by Dave Strickler. 1968 NHRA World Champion, Super Stock Eliminator. Prepped by one William Tyler (Grumpy) Jenkins. It was restored and sold awhile back... Other than the '68 Convertible, this may be as expensive a Gen-1 Zee as you're likely to find!

Didn't they do like 1000 hard launches on a zl1 to test it?

I think it was 600 redline clutch dumps or along those lines...but yes. That's why I love your phrasing - because it's true!

It was absolutely weight as to why the ZL1 rear end wasn't used.

That's one thing I wish they could have put on the Z/28 but I totally understand why not.

Okay so this whole thread is a bust. No one will be taking their Z/28 with the delicate diff and axles to the drag strip for testing. We may never know how fast the Z/28 is there.

I just hope some Z/28 owners will upgrade to the SS diff and axles so we can find out.

Don't think it's a complete bust yet....For sure the rear end of the Z/28 is primarily/optimally made for the road courses....How will it do in the 1/4 mile?....I'm sure it can and will be done, but if it can't take a beating that way, don't think it will be something that's touted as part of the whole package...

From reading some of the above if I was a die hard drag racer, why not change out the rear end with a ZL-1s, and be good to go for both strip and track?...

Might be worth the hassle to get the best of both worlds...

Strickler's Old Reliable was purchased by Camaro expert and drag racer Jerry MacNeish in '93 and fully restored, Jerry raced it in '94 in NHRA Stock Eliminator and won two Division Points Meets and many class wins. In his own '67 Z/28 that he built, MacNeish set the D/Stock Eliminator record of 10.45 at 126.221 in 2010.

I'm awful curious how the consensus has become that the Z/28 driveline components are....."delicate"?

Just because they didn't use the Abram's differential from the ZL1 doesn't mean it'll shatter if you take it too close to a drag strip.....

A sound bite for the competition to seize upon...

GM has stated the Z/28's primary purpose is NOT drag racing, and I doubt their "track warranty" will cover banzai launches on super-sticky 10.5" slicks. Other than that, in the immortal words of Darrell Waltrip, "Have at 'er, boys!"
