I hereby enter this thread! I did four (4) runs in my rather heavy
98 4wd Neo/VVT RB25DE powered Stagea wagon last night. In order they were:
- 17.627 @ 77.21mph with 2.587 60'
- 17.765 @ 76.81mph with 2.636 60'
- 17.758 @ 76.67mph with 2.595 60'
- 17.163 @ 78.57mph with 2.379 60'
And for that last one, here's the slip:

The day before race day, I went to retrieve the caravan to populate it with things and stuff and found this:

Earlier in the evening when we showed up FULLY prepared our secure storage race head quarters looked a lot like this:

And the sky looked like this:

And all was well and right in the world. Some time later my car looked like this:

That's after returning home and getting a spot of rain overnight. The focus wasn't on my car or efforts, as this was just a baseline, so there aren't many/any more photos to share of the mighty Stagea from yesterday evening.
What differed between the runs? Well, in order, these were the approaches:
- Floored it on the green and went
- Held it on the torque converter and got off the brake on the green
- Held it on the torque converter and got off the brake on the green
- Pulled it into drive at 3k to 4k and floored it simultaneously
As you can see, that last ruthless brutal run produced a significant half second improvement over my best run prior. Who knows how many launches like that it'd do before leaving a puddle of ATF on the ground, and not intending to find out, nor wanting to waste fuel on slow runs, I opted out of the free-for-all of grudge racing runs throughout the night and did just these four. The last run technique resulted in a chirping of briefly spinning tyres off the line and then a very similar run the rest of the way down the track except passing the line at a clearly higher speed further into third gear.
State of the car:
- Floor mats removed
- Spare tyre and toolkit removed
- Floor of rear cargo space removed
- Bone stock vehicle with HPR10 group III oil, normal coolant, 200ps when brand new, unknown ATF, unknown diff oil
I reckon with a manual box and a good clutch there'd be another 0.5 seconds out of that time and a much better 4wd 60 foot time. You could probably just dump the clutch at 7k or so and keep it pinned until you hit the shift point.
