Quick question, I saw on the description for the chart that included the RH, and not just the intake and IMG. It says:

We used a DC race header and stock cat back.

We used both the AEM and Injen (short ram), in different dyno tests.

excellent, that was exactly what I wanted to know, thanks for your quick response. I would guess it is safe to assume that with a better flowing catback exhaust we would see a slight gain in addition to what is already shown.

Last question. In your testing, between the short ram (Injen) and the CAI (AEM), did you note any major differences? Was there a reason you chose to pair the short ram with the race header as opposed to the CAI? what were the differences in loss or gain between the two when paired with the RH or without the race header.

Thanks again for your help.

Many cat-backs lose power. Be careful.

The Injen made more power than the AEM on the dyno. However, since the Injen is a hot air intake you would have to do timed runs to see if there was any difference.

A Greek magazine www.powermag.gr had an excellent article a few months back where they tested a dozen intakes, both on the dyno and time to speed for different speed ranges. Some intakes made power on the dyno but were slower on the street, some intakes lost power and ran faster. Some lost power and were slower than stock. Of course, the best intake made power and ran faster...

Question??? I am looking into getting your new re-flash for my 06 civic si and i have done some engine mod's to it already..ie AEM long tube intake and Greddy EVO cat-back exhaust.Will i gain HP by doing the re-flash or is it going to hurt me with what i have done already,im only asking because you said some mod's will hurt you so im wondering if i chose the right mod's so far? Thanks...

You will make gains in the mid range from a lower VTEC, and possibly elsewhere. The only way to know for sure is to dyno before and after.

You will only know once you get the reflash and dyno the car. You should do before and after dyno runs.
