However, the only way I personally have been able to ensure I'll finish a 20-minute main (I also typically run with nitros) without a battery swap is with a "high-voltage low-Kv" setup in my buggy. e.g. Tekin RX8 - T8 1400kv - 6s (3s+3s) 4200mAh 40c LiPo (some people get 20 minutes w only 3300mah, I got 19 minutes
)The High-Voltage Low-Kv setups run cooler and longer while producing the same amount of power. This type of setup should also carry the equivalent (or less) weight due to the lower mah (capacity) batteries required w 6s.

Thorns, I've seen others make 20-minutes with a Xcelorin sensorless 2100kv on a 4s 5000mah Losi battery.

edit: Also, is there any benfit running two 3s packs instead of one big boy 6s pack?

Unless you are using a saddle pack configuration then no. With two 3s packs you have more wires to deal with. There could be other factors though. For example it might be hard to find a 6s pack of the right capacity that fits in the Ve8 battery compartment.

The advantage is substantial if you have a saddlepack configuration as you are able to maintain a lower Center of Gravity by lowering the elevation of all that battery mass/weight by 50%. I can run a 6s system (3s+3s) and have a lower CG and better balance than a buggy with a single 4s battery that is sized for equivalent runtimes. (and obviously a much lower CG and way better balance than a single 6s battery)

I live in So Cal too.
I race 15 to 20 minute mains on 1:8 scale outdoor tracks every weekend unless its raining.. the 5 to 7 minute mains are only at the indoor tracks which are actually 1:10 scale tracks that put up with our 1:8 scale buggies, and a pretty good source told me that West Coast would like to phase out all 1:8 scale racing.

1700 does GREAT on 5s... BUT.. With the new RX8 software you can run the 1700 on 4s with TP2 I believe and have great bottom end thats easier to put to the ground, Good speed, better run times then 1900 AND cooler temps.
So dont be scared of the 1700 on 4s, just ask for settings on the RX8 thread. ACTUALLY I think randy has his 1700 4s setup on tekins site.

Thanks again guys, I'm sure I'll be back with plenty of questions. Oh, and your chassis is next on my list. I actually ruined the stock chassis during the build when I was installing the steering posts
I stripped out the plastic "square" that holds the posts in place. I had to make a quick order from A Main for a new chassis lol. Afterwards I saw your chassis thread and wanted to kick myself for wasting $50 on another composite chassis.

Well I went ahead and picked up the Rx8/1700kV! Getting closer to getting this buggy out on the track. I have a few more questions though!
What length sensor wire do I need? He's sending a 200mm wire but I'm not sure if that'll work. I saw a link in this thread for one that's 270mm so I may just order that one.
PINIONS! I'm going to pick up a few sizes. Anyone have any they want to get rid of?
Based on HH's post, I'll probably start out with 21, 22 and 23. Is there anything special I need to do for those pinions to fit? The reason I ask is I saw something mentioned about the larger pinions not fitting correctly (or I thought I did, I could be mistaken LOL).
That's all for now haha. Thanks for the help everyone.

Besides, running 1/8th scale there has become an exercise in futility. Good luck getting any kind of practice time there unless the track is empty, a rare occurrence. That's why I rarely run 1/8th scale there at all.
