This chart shows the cumulative effects of adding a number of bolt-ons onto a K20A2 Acura RSX-S engine.

One car was used for the first three tests - stock, Hondata K20A2 flash and CAI. A second car was used for the last two tests, Greddy catback and ITR cams with K20A reflash.

Each dyno chart is cumulative - that is it has all the bolt-ons of the charts of lower power.

The next modifications added will be ITR intake, header and Hondata intake gasket.
