I made 3 pulls on a dyno-jet dyno over the weekend. The car is all stock with a K&N filter. It has a little over 4,000 miles on it. I didn't plan to run the Camaro, but the other 2 projects I had in mind weren't ready. The first pull was 288.6 hp/307 lbft at the wheels. Pull 2 was 286.?? and 307.??. The third pull, I swapped the K&N for the AC the car came with. The hp was back to 288 and the torque was up to 311. The dyno operator mentioned that the engine was a bit leaner as well, indicating better flow with the AC. I've had the K&N on it for about 2,500 miles, it's clean and not over oiled. Does this surprise anyone?

airflow changes must be accompanied by computer changes, otherwise computer predicts one thing, and it gets another, freaks out, go into panic mode, and you get way less power than you started with.
MAF is made to deal with a particular airflow tract, if you change it, then the MAF calibration must change with it. |
