Took my Z to 1/4mi drag for the first time
 

Hello Everyone,

Past weekend, I took my Z to drag strip for the first time!

The best 1/4mi time I got was 13.6 seconds (about 104mph)
Below were the condition:

2018 Nissan 370Z Sport Tech 7AT (16K miles on it).
VDC Off.
Shifted Manually.
Launched at about 1,200 rpm.
Tires: Continental DWS 06 (stock size), PSI cold was 32 (later got to 40 due to outside temperature).
Outside Temperature: Was about 90F with humidity.
Gas tank was about half full (93 from BP).
A/C was off, windows were closed.
Engine Oil used: Nissan OEM oil
Altitude/Elevation: 515ft

Only Modifications:
- AAM Resonated Short Tail Axleback
- Added weight of about 50lb due to sub/sub box & amps

With the conditions above, does 13.6 seconds sound about right?
Feel like earlier model years achieved better 1/4mi time.

^ For your reference.

Your time isn't out of the range of predictable outcomes.

Some notes:
-1200 RPM launch seems a bit low for an engine with a decided lack of torque. But the 7AT folks would know better than myself.
-Tires: Conti DWS 06 aren't an awful tire, but you're definitely going to lose some performance versus summer rubber (less relevant here but they have the sidewall stiffness of microwaved butter).
-Temps of 90° (and assuming higher on-track temps) will likely rob the engine of a bit of top-end ponies vs say making the same run in early spring.
-Mods: 50lb extra of sub/amp won't help you shave any time off your runs obviously, but it probably didn't add much time on either. Also, your axleback won't really add any power, but I bet it sounded nice to the spectators hearing you rip down the track ;)
