Thinking Abou A 9L Setup?

[Qball76]

I'm currently running the Novak HV setup and I really like it, but I can't help think that I'd like to give the 9L setup a try, but first I've got a couple of questions for those of you running them.

1) Is anyone running this setup with stock diffs and not ruining them immediately. I don't mind spending cash to upgrade but I would like the initial cost to be within reason. (Translation-I've spent about $1200 on my maxx in the last 3 months so I'd like to buy one of these setups without buying UE diffs right away.)

2) What kind of run times are you guys getting with these under race conditions? Will I be able to finish a 5 minute main running 7 cell GP 3300 packs?

Thanks for any help guys, depending on the replies Mike might be getting an order tonight!!!
