I've found that I get generally 2x my limit rate in no limit. So if you usually make 3xBB/100 it'd be 6xBB/100. This could be because I'm a better no limit table. But I tend to think that the bad players will lose a huge amount more often to you then they will get lucky and win one from you. These huge amounts of wins and unlucky losses should end up winning you more money in no limit.
