Aftee the dif swap, 180lbs weight reduction, wider stickier tires and lighter rims. Ive currently beaten Audi S3, New Mercedes C43 AMG, Mustang Mach E, and 6th gen Camero SS. All from stoplights and im never fully hooking, with trac control off i spin enough to trail smoke behind me.
Dragy coming in on friday, im expecting high to mid 4s 0-60 and maybe mid 13 quarter mile, i need to tune the speed limiter out as it completely halts power at 105 now and i assume that will affect 1/4, otherwise itll just help with my speeding habits haha.
It will be 5.6 at best is my guess but we will see, 1/4 will be 13.7 at best if you did the diff swap but trap speed will be down
The halt of power you feel is the diff gearing I told you about before, it's out of ratio at speed so the top end falls on its face. Same issue as the IS350 of the same vintage with the "party trick" 0-60 gearing special Lexus used in those.
Power over time is power over time. You didn't increase HP so your bottom end is better from gearing but the top end suffered, its physics. You didn't increase the overall amount of work that can be done in a given time/distance just the amount of force under the curve at various points, that reduces it in the top end.

The current fastest recorded ls 460 dragy time is 5.2 0-60 and he was on 235 all season tires. On 255 P Zero summer tires stock i was spinning bad on launches. Traction alone should make my time close if not better. All I lack is a tune and a prepped surface which he had.
There is many YouTube videos of a Ls 460 with a 4.08 swap that was tuned racing up to 150mph. The behavior im getting at 105-110 is speed limiter behavior I still have 2 or 3 gears left.

Correct, you don't have traction and will not especially with the diff swap unless on glue.
The gears do not increase power, they just move the force peak around. You will be slower from a 50 roll vs stock gearing

Im ware, but you gotta factor in the 8 speed too. It’s not the same as a 6 speed is 350 which drops farther out of the power band with each shift. Yes power cuts at 105 but it pulls hard all the way there. The dragy comes in tomorrow ill do some runs tomorrow night.

Yeah....I know that, I have one of these cars lol!
Called it, nothing I did short of an actual track surface got mine under 5.4 actual, more gear just made more spin and KILLED top end.
When you feel a car that actually does a 4.5 you will see the massive difference and how the LS has low end issues on top of traction problems. It's much better IMO to just accept that and use the high end vs pointlessly fighting the launch.
Or get another car, my fast one is 2.2 sec 0-60 but I went with something that is good at being fast instead of trying to force it out of an LS

Best runs of the night, didnt follow through with weights and kept psi 26-28. it sucks because every run I had wheel hop all the way to 10-20mph, on a prepped surface I feel like my current setup is a high 4s car all day. If i do put more money itll probably be a tune or slicks, the 1st gear rev limiter definitely takes a good amount off my runs.

No I knew it wouldnt be a fast car necessarily, i just saw the potential to get #1 on leaderboard and wanted to try it haha. My plan has been to get an ISF this year, ill really try with that car. It would be cool to get high 4s still though.
I tried it at 1500 and 2000 rpm, theres just too much power in my rear for brake boost I fully spin out. Same thing with flooring it, I have to ease into first before hammering throttle and still i get wheel hop.
