I know there are probably a bunch of threads like this but I will start this anyway as I could not find one, I think this could help allot of people decide on an engine if we can get some good info in here, so the engines I am trying to decide on to run in my buggy next year are,

RB Killer-10,

Werks B6,

Novarossi-S21P5XLT-21,

O.S .21xz-b (not out yet but it is the replacement for the v spec)

I have links below of all the engines except the .21xz-b

Post your choice, things you like about them things you don't like about them your experience with them or recommend another engine you have had good luck with.

Thanks.
