With a 6MT, AWD, and those mods, you're probably looking at a 12.8-13.2@107-109mph depending on 60' and density altitude conditions. The problem with the 6MT is that you can't build boost on launch, don't have a torque converter to increase torque multiplication on launch, can't hold much boost between shifts, and the gearing is rather long. The 8AT AWD is far better suited to 1/4 ET. The 6MT is more ideal for roll racing. And a hell of a lot more fun to drive.

Haha. The car stock with 6MT and AWD runs around 13.0 - 13.6. If I can pull off a 1.6 60' in a Z28 with street tires, I'm sure I will be fine launching this car. I only take my cars once or twice to the track just to see how I do. Besides, all tracks are different, but I will be going to the same one I've used in the past.

I got the manual because I love driving. If I do end up spending time on a track, it will be doing autocross.

A 1.6 in a z28 on street tires? Are you talking about drag radials? I too had a 4th gen and drag raced it a ton. I know what those things are capable of. A 1.6 on summer rubber ain't happening. LOL

Tires like the Trofeo R are not drag radials, but they are sticky as hell.

Properly prepped tracks with VHT make a huge difference.

Last time a bunch of us rented out Atco Dragway, and I plan to do it again.

I probably would have destroyed the rear end on the Z28 I owned using radials.

The Trofeo isn't what I had. This was back in 2005. I believe they may have been the Hankook Ventus Z211 or something similar. Sticky, but still considered street tires.

I guess i could see that with some super sticky road course type tires and good prep. I'm convinced the air at Atco is 50% nitrous as that track kicks out absolutely bonkers times compared to most any other track in the nation. That should definitely help.

Be careful with that 6MT and AWD with a hard launch. Don't dump the clutch. You need to launch quite high but with a decent amount of clutch slip. It will be hell on the clutch, but it will save you from snapping something and bogging terribly.

Dyno Tune Results

Finally picked up my car yesterday. I was wrong about it being a Mustang dyno. It was a Dyno Dynamics dyno which is even more of a heartbreaker than the Mustang dyno.

Here is a good article that explains how the different dynos work. http://www.superchevy.com/how-to/ght...el-horsepower/

Overall, I am very happy with the car. Power delivery is much more consistent. The additional torque is great. No issues like I was having with the JB4.

Ok, I was wrong about the 60' time. I actually found my time slip from 2004.

60' ... 1.866
330 ... 5.193
1/8 ... 7.906
MPH ... 90.88
990 ... 10.162
1/4 ... 12.188
MPH ... 115.70

1.6 should be possible with AWD, but I already had to replace my transmission once and will likely be a bit more gentle.

No way you are going to do a 1.6 in the XDrive without launching it hard. Still will be a gamble. Clutch slip will definitely be the drivetrains friend.
I definitely donít launch mine heíll no.

Yeah, I am not going to take a chance dumping the clutch.
