Sidewinder sv2 5700kv vs Sidewinder sct 3800kv

Hey guys I'm new to this forum and brushless setups and Im stuck inbeetwen these two setups... I have been doing my research and I can't decide on one. The new 5700 is now 4 pole like the 3800 and that's basically what's making my decision hard. Btw I have a hpi blitz to install this on. I mostly bash and street race with friends and really want my truck to do wheelies an I could care less about being over powered. " i wana go fast" ricky bobby. So which do you guys think is better. I wouldn't plan on changing my gearing unless needed and it's 18/83.

What batteries do you run? The 5700kv will be faster, but you might have to change the gearing if it runs too hot. It would be too much rpm for most tracks(just wheelspin and lots of it), but if you're just bashing then it'll be fine.

I run 2s 5800mah 30c lipo. I was hoping for more speed. I have seen guys hitting 50mph with this motor but have no clue what the gearing is. I guess ill just need to experiment a little bit. Do yo think i will have to gear down or gear up? My current gearing is 18/83. I've heard of guys running 23/87 with temps no higher than 130.
