Finally Took My 'Stang to the Dyno
343.9 RWHP and 373.5 ft-lbs torque. Here's the graph of my final run. I didn't realize until I got home that they had MPH running along the bottom instead of rpm. Peak torque was at about 4250 rpm and peak hp at 5500. The crossover the torque and HP curve is at about 5250.

Nice numbers. especially the torque!
The 11.8 af ratio that was the lowest, right? looks like it was in the low to mid 12's most of the run.

Thanks. I wish I did some runs before I changed my intake, cam, injectors, and MAF meter so I would know what I netted. It definitely feels quicker so I'm sure I didn't lose power.
11.5 is the lowest it hit and it looks like it was at about 11.8 for most of the run and then it climbed to about 12.3. It was about 12.2 for most of the first two runs I did and climbed to about 12.8. The curve was fairly linear for every run. My first run showed 325.8 hp and 352.5 ft-lbs. I bumped the timing from 12 to 16 and it went to 335.2 rwhp and 365.2 ft-lbs. I reset the computer and let it cool some which brought me up to 340.2 hp and 367.4 ft-lbs. I had a fourth run in there but I guess I forgot to get the printout on that one. I posted the last run.
