I went to the honda-tech meet in Nashville this sunday and they had a dyno set up. I put out 178.9 hp on a dyno dynamics dynamometer with my AP2. According to weather.com it was 99 F and 48% humidity. Everybody was getting low reading. I have an injen cai and espelir exhaust. Another AP2 with 5000 miles on the odometer had a test pipe and put out 173. Supposedly it was reading 13% lower, that gives me 202 hp.

To sum it up, I put out 5 more hp (I/E) than another AP2 that wasn't completely broken in (Test Pipe only).

Low readings due to weather but it was a fun meet.

 

i mean thats a high temperature for a dyno - that could be why everyone was getting low numbers.

 

Bingo. 99F + 48% humidity = Not a good day for accuracy.

 

Could have been the dyno machine as well.
