Best P-body 60 foots?

[Ondonti]

Wondering how much farther until I hit a brick wall on 60' improvements.
This is with a 5 speed.

Have a glazed clutch so I decided to do more careful 2nd gear burnouts (clutch would still slip a little at the end of the burnout). Pretty weak burnouts.
After bogging my first run friday night and talking to my friend who mentioned he was pulling 8psi in his car running off his 8000 rpm rev limiter (sr20 that ran 12's on friday) I decided to launch off rev limiter for fun.

Datalogged and I instantly build 5psi boost on my t67 P trim when sitting on the limiter.

Pulled a 1.75 60' Clutch slipping badly though..hitting the limiter multiple times in first.

went 1.83 because I short shifted (hard to tell when to shift with the clutch slipping or possible slicks slightly spinning)

1.76 when I decided to wait to shift when acceleration seemed like it was slowing down.

I was happy with the 1.75 and 1.76 but I dont know if I can get much better. I am hoping if I fix my clutch that I can get better burnouts and be able to put more power down in first gear. Not switching to auto anytime soon.

Launching with 5psi is great and the moment I drop the clutch I get full boost (whatever I have it set to). I know at higher boost levels this wont work because the slicks wont handle it but I dont really care about those power levels right now and at that point I would probably look at boost per gear setups.
