I didn't feel like creating a new thread, so I'm gonna dump it here until I unlazy myself and create a journal for this car. I went out to the drag strip again yesterday while everyone was getting $hitfaced for St. Patricks day. I was hoping to hit low 13's @ 105 mph. I know the car can go faster, but conditions were not the best. It was about 71 outside and 85% humidity on my best pass. I was running on stock tires with plenty of tread and 32PSI per tire. I made no PSI adjustments, literally just drove up, turned off VDC and went. Bradenton Motorsports track is 19ft above sea level. DA was calculated at 1020ft and a relative density of 97%. I was able to hit:
13.466 @ 104.67mph with a 2.134 60ft
13.572 @ 104.85mph with a 2.21 60ft
13.604 @ 104.35mph with a 2.204 60ft
I was averaging 13.6 unless I missed a gear or bogged the launch. I hit 104.88 a few times, not quite 105mph. My previous best with just intake and exhaust was a 13.695 @ 102.79mph.
A normalized time for my Jan run is 13.624 @ 103.296 MPH
A normalized time for my last pass is 13.328 @ 105.756 MPH
A normalized fastest trap from Jan was 104.2mph
A normalized fastest trap from last night was 106.3mph.
I would say the 15whp I gained from a tune is definitely showing up in my 1/4 numbers. I improved by 3 tenths and 2mph from just RTP's and a tune. I was hoping to see a true 13.3@106 mph last night, but I'm happy with my results. DA correction at least tells me its perfectly capable.
On another note, adding headers, upper/lower manifolds, and those new filters from Z1 and a retune, I think I can crack 13 with my crap launches and possibly hit 108-110mph on stock tires. I'll post up a video of that pass later tonight. I'm at work shamming on the370z.com.
