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. Norm |

.....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 |

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 |

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.
