I just want to add my 2 cents here. I went with a rsx-s from a roll at about 30-35mph. He had a intake as far as I know. I had a UTEC and full exhaust along with a up pipe. Well needless to say I pulled on him on every gear. We went to about 100 and I had 3 cars on him. Now stock for stock, the rsx-s would probably pull from a roll, but not by much. Thats my alnalysis.
