mobeydick Posted September 2, 2007 Report Share Posted September 2, 2007 I just took my 07 GT500 to have it dyno-ed, Before I install an Evo. Stage 4. Not the numbers I though I would get. I'm Not very happy!! 368 RWHP 364 RWTQ Brand New Mustang Dyno. Today, Saturday Sept 1, was his first Day of Busness. I don't know if he knew what he was doing.

mobeydick Posted September 2, 2007 Author Report Share Posted September 2, 2007 Was it hot? I think the Mustang dyno numbers are usually low? It was about 80 100% hum. Not raining there but it was everywhare else. Link to comment Share on other sites More sharing options...
GT500FLYBOY Posted September 2, 2007 Report Share Posted September 2, 2007 Very normal. Don't worry. Here's my best stock run on a hot day...it got as bad as 340hp. I'm sure if you looked, your AFR would have been way low. When the motor gets hot, the ECU dumps fuel to keep the cats cool. Drops performance dramtically. The motor runs best in the 60s and 70s. Dyno runs should be done quickly and with a cool engine. Link to comment Share on other sites More sharing options...

kaylan1521 Posted September 3, 2007 Report Share Posted September 3, 2007 Did you put the coil pack covers back on? That makes a big difference on the dyno. Link to comment Share on other sites More sharing options...
mobeydick Posted September 3, 2007 Author Report Share Posted September 3, 2007 He didn't hook anything up under the hood. Only the EDP. Link to comment Share on other sites More sharing options...

BlackVert Posted October 10, 2007 Report Share Posted October 10, 2007 Did you put the coil pack covers back on? That makes a big difference on the dyno. Really? Has this been the experience of many others? Now I'm wondering what my numbers might have been- they were left off yesterday during my dyno...

SteveTheMechanic Posted December 20, 2008 Report Share Posted December 20, 2008 I took my 07 to the dyno in December of 2006, about 400 miles from new, it made 365 hp and 380 torque the first time, now a KB Stage 3, I'll go back & see how it does now Link to comment Share on other sites More sharing options...
