RSX Intake Horsepower Test
Intake Test #2
We are starting with this test because it is the most in-depth test and is a much better representation of the performance of each intake. The second intake test was done on January 31st, 2002. We tested all three of the intakes again, the Injen short ram and the AEM cold air & short ram. We used the same AEM cold air and Injen short ram as the first test but we did use a second AEM short ram because of poor results from the first test. Because of certain member opinions from the first test, all of the installs were done by Tobi Connell of TC Performance and no one from Club RSX installed any of the intakes. This was done to ensure the accuracy of each test. There was no change to the car from the first test other then doing an oil change an hour before the test was done. After poor results from the first intake test, we did follow AEM's dyno setup and procedures that they use when they test intakes. This included a fan at the front of the car and at the rear of the car and had a time period of three to five minutes between each dyno pull. These tests were done on the same DynoJet as the first intake test.
This was a better overall test procedure wise but we feel the results were mixed. The Injen short ram produced almost the same numbers as the first test but the AEM cold air and short ram did quite a bit better. We are not sure why this was but we feel that you can't look at each test by themselves but look at the results from the first test to the second test together to make up your mind.
Order and Temperature
The Injen was first and the temp range was 71.4 to 68.8. The AEM Cold Air was second and the temp range was 67.8 to 61.0 (the actual last run with the AEM Cold Air the temperature reading was off, showing a 54.6). The last one tested was the AEM Short Ram and the temp range was 63.8 to 59.5.

Intake Test #2.5
This test was more about testing two new intakes then it was comparing intakes all together like the first two. This time around, the car was much different and had a lot more modifications done to it. This time the car had a Hondata reflash, Jackson race header, and an Injen SES exhaust. This test was to see how sell the AEM V2 did compared to the Injen cold air intake. The tests were once again done on the same DynoJet as the first two tests.
Injen Cold Air - Average: 194.5hp & 135.6lbs
Run #1 - 98.2hp & 129.9lbs - Aborted Run - Problem with tach signal

Run #3 - 194.7hp & 135.7lbs - 5 minute cool down before run

Injen Cold Air (Hot Run) vs AEM V2 Short Ram (Hot & Cold Runs)
Intake Test #1
The first intake test was done on December 17th, 2001. We tested four different intakes: the stock air box, the AEM cold air & short ram, and the Injen short ram. We did at least four pulls for each intake and we did the pulls back-to-back. We did it this way to simulate real world driving and to see what would happen with each intake as the motor got warmer. The dyno used was a DynoJet roller dyno. The only modification done to the car was a Magnaflow exhaust which was the same size as the stock exhaust. Overall the Injen short ram out performed both the AEM intakes in both normal and high operating temps. The one we were the most disappointed in was the AEM short ram. We found it lost power over the stock air box for some reason.-
