My friends, I’m having fun to say the least!

See updates in comments with times for 7 launches (3 on track) and another video with the view from the stands.

Update: Took morning off PTO to assemble data, videos, pictures... long and arduous. But here are initial best splits / times of three runs. Not the best, but keep in mind only had ~70% battery charge, NOT in Unbridled Extend track mode, tire pressure may be high at 42psi, etc. Definitely probably will do better as soon as I get back on the track with some changes. Still pretty good 0-60(1ft roll) at 3.78 seconds (on road).

Track Splits:
1/4 mile: 12.657 sec @ 100.02mph
1000ft: 10.433 sec
1/8 mile: 8.03 sec @ 86.67 mph
330ft: 5.26 sec
60ft: 1.99 sec

Dragy in same run:
0-10 in 0.58
0-20 in 1.20
0-30 in 1.80
0-40 in 2.44
0-50 in 3.21
0-60 in 4.12
0-60(1ft) in 3.89

On road test 40 minutes later, I recorded a 3.78 0-60(1ft roll) and 192.13 distance, no squeal of front wheels. (again, all traction control on)

Notes:
  • Will publish more tonight/tomorrow
  • Full road safety measures on - this is NOT in track mode (ie. called Unbridled Extend), so all traction control, etc. are on. Next time will try with track mode turned on. Likely get better results.
  • First time on track, but think I did pretty well at launch hitting the last yellow/green.
  • Battery charged at only 72% at start of track tests --- traveled 50 miles to nearest charger 20 miles from track, charged to 80% then drove to track, result 72% at track
  • Tires - cold pressure are 39psi, warm was reporting 42psi
  • Top speed seems to be governed with little acceleration past 100mph, max got up to about 108mph without Unbridled Extend turned on.
  • Admittedly, driver/owner is heavy set - plus video & photo gear, mounts, +125lbs over std driver with no cargo
  • Track was heavily used for three days, I get in at very end and had the last two runs of the day. Temp 79 degrees.
Questions/Notes:
  1. How to charge near 100% at track in rural areas? Track owner and I chuckled when I asked if he had 240V outlet anywhere.
  2. Should tire pressure be lowered for test on drag strip? (if so, what pressure?)
  3. Front tire squeal due to front end rising at launch, creating lower traction, does it make sense to add weight to the front for more traction?
  4. In Unbridled Extend mode, if no traction control, is it best to keep the go pedal at max and spin the wheels? Or lighten up? That could take some trial and error.

Road time - 6:22pm - this one, I may have let up on the throttle towards the end.

It actually squeals when it takes off, awesome! I'm sure all the questions will be answered when you post more.. like its times and if you had the "defeat" button on (making traction control fully off), state of charge during runs, etc..? ( :

Thank you for posting. I know what it is like to be busy with work. I'm just glad it was you that got your gtpe first and not me. 😛

I'm equally glad to see you having some fun. Well deserved. Thanks again. Still waiting for mine. Good things come to those that wait. 😀

That's about the same amount of wheel spin I got on dry pavement jumping on the interstate (even while cornering). I'm not sure if the VHT at the strip was fresh or not, but I would expect it to just hook and go. Curious if you had TC off when you launched?

Well, I did it! Gotta get to bed but have some great stuff to share in the next few days! My friends, I’m having fun to say the least!

Fun. Looks like the wheel spin was caused by the front end lifting up at start.

Bold predictions:

60ft time between 1.77-1.88 secs
330ft btw 5.15-5.25 secs
1/8 mile ET btw 7.95-8.04 secs
1/8 mile MPH: 88.00-89.5mph
1/4 mile ET btw 12.2-12.40
1/4mile MPH: 111-113.5mph
Caveat on the 1/4 mile ET/MPH: predictions based on OP staying in the throttle through the traps, I’ve seen way too many people lift early in my time.

That said, it appears the OP left on the third yellow in order to cut a good light, and leave on green, so, I’m thinking he’s done it before 😎
