Interesting... my best runs, 99 GS400 with SRT intake/ecu:

14.385 @ 99.391 , 60' was 2.181, 1/8 @ 9.311
14.41 @ 101.3mph

Clearly your launches are amazing, 1.9 60' is impressive. What is your technique? Do you hold the gas/brake together off the line? 3.76 LSD and TC are my next mods for sure!

Over a couple dozen runs with only the TC and or headers...heck, even when stock, I found that my ET's were the same whether I stabbed the gas or whether I brought the RPM's up against the convertor.

Since adding the supra rear-end, I am getting better 60' times by launching 'on the convertor' as much as the track will hold.

My 60' was like yours before the TC, when you do get one, you'll go down to the 2.06 range with traction.
The headers brought it down again to the 1.96-1.99 range.
The rear end and new launch technique brought it to mid-low 1.9's. Even a 1.88 once.
I gotta say, my local track has decent prep but I think these Pirelli's at 245x45x17 are also a big help. They just stick!

Your ET/MPH look good to me. You're easily on-track to duplicate or better my times.
