I was able to make seven passes.
car: 1988 Mazda RX7 SE
Engine: 1999 Chevrolet LS1 5.7L (stock)
transmission: 4L60E (stage 2 Performabuilt), 3500 stall
Tires: Mickey Thompson ET drag 28x9-15, MT ET fronts 25x4.5-15
Mods: T2 diff, 5-lug swap, poly bushings, KYB AGX struts, 150# rear springs, Hurst Quarterstick shifter, shorty headers, X-pipe.
will post up a pic of the timeslip if you'd like later...
the best run, 12.113 @ 112.44, had my worst reaction time... best R/t was .170. I need to work on that.
r/t: .968
60': 1.669
330': 4.961
1/8: 7.725
mph: 88.6
1000': 10.109
1/4: 12.113
mph: 112.44

yes, in fact the T2 diff can go up to ~450 hp/tq. some guys are going faster than me with NA diffs(but not many). when I first put the car together, I was launching hard on an NA open diff. it all just depends on how hard you're hitting them, manual transmissions are much harder than autos on diffs, a clutch drop transfers a much greater shock load to the ring/pinion/axles... most likely fail point is the stub shaft, occasionally other points.
Oh sure, I forgot you were running an auto tranny and that does take a huge load off the diff when launching. That's definitely a respectable e/t without engine mods and using an auto.

yeah that is a good time on the stock motor, im running a close set up, but lt1 instead of ls1 and a 700r4 with full corvette internals and b&m shift kit, but no slicks, just some proxies. but are you going to the track any time soon again?
