Anybody else have one of these? Would love to see other cars times
This was in the rain. Will try and bring to track to compare how accurate it is. If it’s good enough for motor trend and car and driver etc that works for me.

Car is a fbo 2011 g37x 7a/t sedan
Mods at the time of both runs (both runs months apart/ traction control off/second run is in d):
Stillen g3 2.5 inch intake
Oem ported 63mm throttle bodies
Z1 plenum and z1 intake manifold
Stillen ceramic headers
Fast intentions 2.5 inch test pipes and 2.5 inch cat back exhaust
Uprev dyno tuned by Jon at z1 motorsports 2 years ago. 321whp/264tq. Car weighs roughly 3680lbs (without me I’m 170) at time of these racelogic runs (1/4 tank)
Since he tuned it I have swapped from z1 hfc to fi 2.5 inch tp, added gtr plugs, changed the cat back from 60mm top speed exhaust to 2.5 inch fi exhaust


Cooling: csf radiator/z1 oil cooler
Fuel/ignition: factory except gtr plugs (didn’t change gap)
Suspension: stiffest setting all around on k sports/full spl catalog
Wheels: 17x8 rpf1 on Michelin a/s 3+ (35psi)
Stripped trunk 1/2 tank each run (shell first run/bp second)
no passengers

13.0 quarter mile 107.6mph . 1.9 60ft.
4.5 0-60
11.2 0-100
0-100 broke down
0-110
Max g pulled on launch


Another run for before switching setup:




0-60 0-100



0-60 0-100 30-50 50-70



1/4 mile and 60ft time



0-100 breakdown

 

I presume it gives instantaneous 1/4-mile numbers instead of the track's 66' average at the trap. Which means your meter is more accurate but not truly comparable to a drag strip read-out.

 

Ended up running 13.3 @105 in November at Atlanta dragway in commerce ga(first time ever to the track). My 60ft was 2.0 at track when I ran and it didn’t feel as fast as the consistent 1.9 on the street. 0-60 was also worse at track by .3 (4.8 at track, 4.5 on street)

Very accurate. When I ran them both it was within one mph and .1 overall time.

Main reason I collected this data is to see what the new admin 3 inch intakes with eps 70mm Tb along with retune (to get arc update and perfect tune). I’m very happy with 0-60 as it is, but hoping to improve my 60-110 (110 is the highest I’ve tested and have data for on my old setup to compare new setup)

GOAL of all this! To run 0-100 in 10.xx seconds with new setup and hopefully break into 12s n/a without e85. I will re dyno after to see what new setup makes.

 

Try the 0-100-0 test. Nowadays, they run to 150 since cars have become so damned fast.
