Looking at getting an RB engine for buggy, I had great luck with them in the past, but have some questions, is the Killer 9/Killer 10 a decent engine, I know these are no longer nova based, or is there another recomondation for a decent RB engine at a price less than $250
I'd say its a great engine for the price. It can hold it's own against some of the best motors out there. Its been one of the best motors I have owned and I've had WsIII and c5 and c6 motors. the low end is better than the ws3 and top end like a s7. For the price you can almost get 2 k9s for 1 b9/10.
mine pulled on a vspec pretty good in this video and I could have caught him but he would have put me into the wall if I did lol.
