I don't know what your Riptide weighs but I think it is fairly short and should have very good performance. I think the complete header system adds about 50 more hp on the 8.1. Headers,FF mufflers,CAI on my old 454 added about 80 hp. This translated to 40-60 mph test going from 19 sec to 14 secs. Increasing the timing from 4 degrees BTDC to 9 shaved 2 secs more to bring it down to 12 secs. I don't know how it will effect the performance on the 8.1 but for no cost it was a great increase in performance. You might try this 40-60 MPH test first to establish a base line, then you can see what the performance mods actually do. Also once you know your baseline you can extrapolate what others have posted about methanol cooling etc. It's hard to find actual performance data most just report a big improvement or some other subjective words. A guy I met added a cooling system to his and I think it took 2-4 secs of his time if I remember correctly.
