First let me say that my dyno #'s from over a year ago where 304.6 rwhp and 338 rwtq. That was with FMS shorty headers, MAC h-pipe and a Flowmaster catback. That was probably at ~160,000 miles.
Now I've added a Magnaflow catback, Pypes X-pipe and BBK long tube headers. I currently have 176,500 miles on a stock short block.
New numbers from the same dyno. 301 rwhp and 323 rwtq. Got the same numbers adjusting the A/F ratio from 12.5 to 13.1 The car blew out a ton of smoke after the run, and smelled really rich.
The parameters on the new dyno say 84 degrees F, but it was around 68. And it also says 8% humidity? This is an import dyno shop, there were 7 VTEC engines laying on the ground (seriously!). The manager was convinced that my AFM power pipe was a turbo. So I'm not sure if the lower numbers are from the high mileage and abuse or the dyno operators. Most of my friends in town have gained alot of hp and trq switching to long tubes. Unfortunately the next closest dyno is 2 hours away.
I'm hoping to get out to the track on Sunday to get some numbers. The guys at the dyno had difficulty printing out a graph and could only give me a speed vs hp/tq variable. I'm hoping to get a rpm chart tomorrow. The pull started at ~3500rpm and stopped at ~6200rpm
I'll try to post some graphs later tonight.
