With the way your shooting nitrous now a 1.7 60ft which is the lowest short time recorded on an IS-F with drag radials, should yield you a 10.80 at lower MPH.
I would, shoot less nitrous off the line in 1-2 gears and ramp it to full power in 3rd, using a progressvie controller like Staman mentioned. This should get you a 1.5-1.7 short time and get you a 130+trap,good for a mid to low 10 sec time.
Slay nailed what I was saying, Im guessing this direct port is easily topping a 250shot to get that sort of MPH. A 250 shot may sound extreme but it really isnt for a factory built 5.0 V8. I would say its more extreme, or ballzy to subject the stock trans to that abuse. They may work great but the up/down shifting solenoids have busted on these trans with less tq.

Video of the Pass:
It was done on Michelin PSS 275/30/19s - Full Weight. Could prolly hit 10s with DR's and a better 60ft. Im most impressed with the trap speed! should have seen 10s with a 133mph trap but traction is a killer! anyways enjoy

Yeah I agree. Id be a lot more worried about the transmission and the rear differential than the engine internals, especially in a drag scenario. The ISF has a tough V8 so i wouldnt worry about the rods or the heads etc...What I would worry about is the detonation and the timing with 250 shot. You can probably stave off the detonantion with race gas and colder plugs but I don't see how to solve the timing issue. The timing can be retarded but apparently the F ecu immediately changes it back. I havent tried personally. Slay, rider, dv8, what are you guys doing about the timing.....
Having driven extensively an ISF with and without LSD, I'm sure the slipping that you feel is the LSD. Post-LSD ISFs might be faster than pre-LSD ones around a road course, but not at the drag strip. I hate that "delay" or "slipping" feel that you refer to, I have it on my 2012 and never had on my 2008.
I wouldnt pay much attention to the pre lsd diff. it seems pretty stout and i didnt pull any one leggers.
I never ventured higher than 175, and that was on the street. I was going to run it at the track but, I got the GT-R instead. I never ran into any issues other than having to refill the bottle. Best way to describe the ISF on nitorus is smooth-fast-with an awesome tone.
I'd love to race me some Slay in GT-R come April
I know you like beating them in the F.
