Hi,
   How was your application runnin on non-RAC machine? Was it running fine or are there any problems? If you have problems on a single instance, then there will be lot more problems on RAC database.
What's the biggest wait event on the RAC database? is it "gc cr block 2-way"?
What's the parallelism of the indexes that are highly used? If the parallelism is set to a high value, then there will be processes started on all the nodes for each query and there will be lots of inter-node traffic which will effect your performance on RAC database.
Can you please send the AWR report of the instances? It would be easier to monitor the RAC database on Oracle Enterprise Manager.
HTH
Regards,
Badri.
