I am looking for speeds comparable to my Nitro, so about 40mph give or take. I also believe that the runtime (with the ones I linked) would be at minimum 10 min longer than a 5000mah pack. Right?

40mph will be easy for those batts. Run time is kind of difficult to guage but 8000mah will last almost twice as long as 5000mah packs. I am no big fan of 4000mah lipos, but when you parallel them in the configuration they have, they hold their voltage pretty well.
FYI, I took my 7xl out to a parking lot and was about to race a .28 tmaxx with 30 percent a couple weeks ago and everyone agreed my setup was far more impressive on the torque and acceleration. This was with the spc packs peak charged to 7.45. Nitros take a bit to get up and going, but these electric setups just have crazy low end torque.
The Neu batts these guys are recommending though are going to have greater punch than the SPC's, and they make great recommendations, but if I get any more torque in my setup somethings is going to give. Right now it holds nicely together with all of that power.

So you have the 8000 SPC lipos then? Are the battery temps good?
I think that it is a close one between the SPC's and NEU packs. I can't decide which way to go.

Just buy the Neu or FP and be done with it.
