I know that’s what it seems like from gathering your data from above, but for what it’s worth I lined up with a 9th gen si a few weeks ago and we both we both got on it at the same time. Needless to say I walked away from him hard. My only mod was a ktuner with Vit Stage 1 (unnoticeable from the 23psi base map). I since then have only added a flex fuel kit and I go out to local meets with cars that are in the 102 mpg trap speed in the 1/4. I either stay with them or gain a slight edge from a rolling start.
Now a full bolt on 8th/9th gen si CAN pull away from a ktuner/ hondata flashed 10th gen, but it will take a lot more money.
My point is I have 2 mods and a bolt on previous gen si wont touch me. We do need more time slips of other cars for comparison though. I know someone on this board has an ex-t and traps 102 as well.
If anyone here is in south Florida and wants to ride to PBIR tonight for test and tune let me know !
I'm in SW FL, closest quarter to me in Bradenton, Immokalee has an eighth mile. Definitely down for meeting up and see what the cars do

Back at the track again, and at the very least---it's time for new tires!

Played with a few tunes last night. Here's the 21.5psi Si KTuner basemap (on-the-fly configuration 3), sport mode on, VSA manually disabled, and launch control was set at 3150rpm. I got some unexpected wheel spin combined with a little rev-hang (and my sloppy shifting) from second to third---but the fastest run I've had so far. I was lined up with a Camaro of some kind.

r/t: .587
60': 2.289
1/8: [email protected]
1/4: [email protected]
mpg: 31.3 ;)

I would dare to say if you if up your boost ramp rate and run 23psi you’ll trap closer to 98-99.

I’m running 23psi with flex fuel on stock clutch. Going to be my first time with this car at the track next week. I am hoping to break into the 13’s. I’m untuned, only running the base map, but it’s holding the power as long as I don’t punch it at a low rpm, i.e
4th at 3,000 I’ll notice the clutch slip

Quite a few CVT's trapping +100mph on just the Ktuner 21.5psi tune... I beleive it is the 1-2 shift that hurts the Si the most... even with all the nannies disabled.. I havent followed along too much but and engine and transmount upgrade should help this. I think an Si should trap the same as the tune only CVT's but something in the gearing is too long... so yes 23psi should get you there.

I am planning to go up to 23psi myself to hit a 101-102 if possible. Tune only. I have two friends with 10th Si's and we have gotten to track together a fair bit.

The one Si sedan I roll with is now dropping his Vit tune.... he has been stuck a 14.55 for his best time, at 95.5mph and is going to try setting up his own tune himself using the Ktuner.

It's not looking good for me either, already well into overtime and probably be working all weekend. Definitely not a typical work week for me but we had 2 guys quit this week and we fell behind on a 2 week remodel. Never know tho, miracles happen lol

Alright so I just got back from my first time at the track.
Let me just say, wow this car has the worst wheel hop I have ever experienced. It shows in my first time slip of the night:
60’ 2.620
ET- [email protected]
Run 2 (missed 4th)
60’ 2.248
[email protected]
Run 3
60’ 2.319
[email protected]
Run4
60’ 2.282
ET [email protected]

Tire pressure was 34 and it was 86 degrees out.
Was hoping to break 13’s and 100 trap speed but it didn’t work out tonight.

Not bad at all. A 2.18 60FT should have put you at 14.1. - 14.2. Looks like you'll need fairly cooler weather, or more power (trap 102-103) to break into the 13s though.

Any recommendations on tire pressure ? I tried the launch control at 2800rpm and I thought I was gonna drop the tranny there with the violent shaking lol
