What winds did you order? what cells do oyu have?
Dead shorted packs can be the ticket if you know how to set up a mod motor and or have a smooth finger.
I recently just did some tests with sample IB3800 pack, here is what I found:
I took a new pack and cycled it on my GFX.
Runtime was 375@ 35 amps ( this was a low runtime pack to start with) with 6.99 voltage ( 5.40V)
After dead shorting: ( 3 weeks)
Runtime is now 343 and voltage is up to 7.08 ( again 5.40V)
If you take that 343, that is a decent time to be playing with in Mod. depending on your track and your finger you might just have a killer mod set up and you do not even know it.
Remember- last years racing ( or even ROAR this year) was (is) all done on the GP 3300. A good GP pack was in the 345-370 range ( again @ 35 amps)
Most of our team ( SMC) that run a 10 turn limit or our Euro drivers (12 turn limit) dead short their packs.
I don't know what #'s you have or started with but I would encourage you to find a GFX and give them a cycle to see how much runtime has been dropped from DS'ing the pack.
I recently just won a large carpet race ( foam, DC 9x1 UL) with a IB 3600 pack that I was messing with. runtime on that pack was down in the low 300 range LOL...that runtime is pushing it, but was still possible to race hard and win.
I am not telling you to do the above, but just think it out and see what you have before you go out for no reason. If you ordered 7 turn UL's and run on a long high bite track.. then I would be ordering new packs...
Hope this helps
