I agree 1/4 is not be all end all performance test but like others said, its gonna be tested in the 1/4, and there will be people who take it there. Maybe the OP just wanted to know if someone challenged him at a stoplight how the Z/28 would fare, or maybe he was just stirring up some conversation.

these are just some of the posts that came off to me as a bit aggressive, its not like the OP asked what it was gonna take to put it in the tens.

And I see where all the Z/28 purists / corner carver guys are coming from too. Yeah the Z/28 is not gonna be a monster on the 1/4 but thats because its going to devour pretty much any car on the race track because thats what this car was built for. That is where this car will excel.
For sure it's all about the track and whatnot...I get that...but to not take a 427 Camaro down the 1/4 mile?....Who could resist that?...lol...

I wouldnt be able to resist that. Hell if I had a Z/28 I would hit up the drag strip for sure, then the next weekend hit up a road track and vice versa.

One of the reasons I would hit up the drag strip, to piss people here off hahahaha but the real reason would be bc I can bc it would my car and I can do whatever the hell I want with it.

I'm afraid that drag racing a cornering car is one of those "hot-button" topics that will always attract a few heated responses. Just that it may not be widely recognized as such outside the realm of corner-carving.


At my own levels of dragstrip skill(?) and (in)experience, it wouldn't be a snap decision for me to ever drag race a Z/28 even though Atco (apparently one of the places with generally better atmospheric conditions) is only 15 or so miles from my house. Too easy to embarrass both myself and the car. I wouldn't even bet on salvaging enough for a good "if only" bench racing/excuse session afterward.

.....ZL1 is made to launch hard, at high RPM's, and even with slicks on it...it's been beefed up mechanically to unbelievably high standards for OEM factory equipment..., now as far as the 1LE, Z-28 rear axle and shafts <likely they will be the same>....dicey proposition for drag racing with hard launches...just sayin...not designed for it, But they will be at the track horsing around in the '1320 non the less. Dumping the clutch isn't required in road racing....and there may be something in the warranty to reflect that. Who knows...

a couple of guys have gotten a bone stock with stock tires Z06 into the 10s. A lot are in the 11s.

With drag radials a few more have gotten into the 10 second area.


This camaro is what 300-400lbs heavier but with a drag radial and a great driver - i would think a very low 11 or maybe a high 10 would be possible.

Dumping the clutch at 5000rpm is never ideal (unless you have a beefed up drivetrain and proper slicks) for a launch.

With drag radials and with the gearting - i think this Z/28 could be a monster at the drag strip. I expect to see a few of them once they start rolling out of show rooms

A Z06 is actually about 625 pounds lighter than a Z/28. According the Chevy website the Z06 curb weight is 3175. Everything we have seen on the Z/28 suggests it will weigh about 3800. I doubt it will come anywhere close to a low 11 on just a DR

I had this in a different thread, but thought it fit here better.


This IS "Over" 500/500

POWER-TESTING THE FINAL PRODUCT
Livernois Motorsports is experienced at building all kinds of LS engines for street
and racing applications. The company likes the LS7 as a wet-sump engine
because it makes just as much power throughout the rpm band as the stock
dret-sump, installs anywhere a normal LS V-8 engine would go, and has incredible
street cred. The wet-sump LS7 is not for customers wanting a track-ready Pro
Touring car—in that case, the dry-sump version of the LS7 is ideal.
Note: Power numbers are all corrected using correctionf factor SAE J607 (29.92
Hg, 60 degrees F, dry air) and testing was performed with the GM Performance
Parts controller (GM PN 19166567) handling fuel and ignition.

Well said!
I recall close to a 100 lbs were saved using the 1LE diff and half shafts over the ZL1 unit.
Additional factors that may hurt the launch is the reduced weight transfer due to stiffer shocks/springs and lowered stance.
The last item I have not researched thus am just guessing, but typically track cars have closer gear spacing between 2nd, 3rd 4th and 5th leaving a tall first gear and big gap to 2nd (not good for the drags with sticky tires, easy to burn clutches and/or bog).
I believe 6th will still be used to knock down the effective final drive using the 3.91 rear to get good mpg.
If any one knows the actual Trans gear ratios that would interest me to compare to ZL1 and SS

Is this testing on an engine dyno? If so, then the 555 hp @6100 rpm would net 471.75 rwhp with a 15% parasitic loss, correct? What modifications were done to the motor for them to have gained an additional 50 hp over what the Z06 had?

No modifications on left side dret sump, converted to wet sump on right side.

So just changing one side to wet-sump adds 50 HP?

No one side of the above spreadsheet. The engine obviously has more power than GM has advertised. Hence the "Over" 500/500 in their Z/28 marketing.
