I think I have seen some info on 1.8:1 converters versus the stock 2.2:1 (torque multiplication factor) - that may be all there is.

So if Stage 2 is 280 x 2.2 = 616 ft-lb input into trans
and 616 / 1.8 = 342 ft-lb crank torque(not bad).

I've been thinking about this. Here is what I came up with. As long as you don't hammer it in low or autostick 1 you will be okay. If you do hammmer it, all you are going to do is to go up in smoke anyway. Another thing to consider is where are you making max torque at. There will be lot more strain on the drivetrain with 342 ftlbs of torque at launch then at 40mph. looking at the S1 HP/Torque chart max torque was made between 3.8k and 4.8kRPM. The car should be doing between 60 and 80MPH by then. So the additional torque shouldn't be a problem. Finally, I'm making 258flbs of torque at the wheels now which is 327 ftlbs (corrected) of crank torque. S2 will take it out to 270 ftlbs or so of torque at the wheels. But even then I "won't" make max torque at my launch (1500 rpm). Finally as we change the engine configuration the HP and Torque curves will change also, however the RPM range should be about the same since longevity was taken into account. All this was taken into consideration by the PVO team during RTD&E.

So my points are:

1. As long as we are below the max torque rating for the tranny at launch we should be good to go.

2. We are making 300+footlbs (corrected) torque at the crank with S1, now.

3. S2 should get us (est) 342.09footlbs (corrected) torque at the crank (270ftlbs of torque at the wheels). We should still be okay as long as we launch correctly

4. As long as we launch correctly we should have nothing to worry about.
