I wouldn't reccomend the 3port Rody for ROAR racing, first of all I'm not sure of the port mods Rody did, so it may not be ROAR legal anyway, second of all you'll get a lot better fuel mileage from the stock 3 port and it has plenty of power for a 45 to 1 hour main.
I also have the 5 port Rody for outlaw racing. Yes it is insane fast
