LS1 Datsun 280Z Dyno/Track Results So this past weekend we had a dyno day here in NW Arkansas so I had a chance to get my 1978 Datsun 280Z on the dyno and do a little tuning. My setup consists of a 98 LS1/T56 with 799 heads milled .035 for around 11.5:1 compression. My own custom built longtube headers. Stock LS1 intake, stock cam. Tune that could still use a bit of polishing up, but its decent. Anyways on to the results/pics/videos.
Dyno'd saturday morning on a Dynojet. For comparison a 98 Camaro with nothing but headers and a slight tune put down 330/341 torque. Anyways my final results after 4 pulls and a couple tune tweaks were 348rwhp@~5500rpm and 370rwtq@~4500rpm. Tune could still use some tweaking, tried to do some more logging at the track, my launch/1-2 shift were shorting something out or causing my buddies laptop to stop logging, so I was only able to get one log when I just rolled up to 3rd and 4th gear.
And on to the track results. My best time of the day ended up being and the video is of that pass:
60ft: 2.0217
330ft: 5.3256
1/8 ET: 7.9681
1/8 MPH: 93.91
1000 ET: 10.2482
1000 MPH: 108.04
1/4 ET: 12.1520
1/4 MPH: 118.33
That poor fox body never stood a chance lol.
This is the second time I've gone to the track on the same axles, normally I break them on a daily basis, but the one thats in there now must be made of unubtanium or something! I was shifting hard the last few passes as well, almost WOT shifting 3rd and 4th, launching pretty decent, and was getting lots of wheel hop, and it kept on going.
If my local track back home was a 1/4 mile instead of 1000ft I know it would do 11s without changing a thing, I pulled a 10.06 in the 1000ft at my local track, and my MPH is up 2+ from that 10.06 pass.

Thanks man, its a fun car. Can't wait to get some axles and slicks on there though! Guy I bought it from weighed it at 24xx with the iron straight 6 with a turbo setup, so I'm sure it still weighs in the 24xx range, I took out some stuff from behind the dash as well, no more a/c parts, etc. Can't remember his name on LS1tech, but he has a 280Z with a H/C LS1 and he was running 11.0x on some slicks but was breaking his CV axles that are a "lot" stronger. Pulling a 1.5/1.6 sixty it should go mid 11s no problem
