Went to the dyno to see if or how much the headers helped my car and I was amazed...
On Rick's Mustang dyno at Amazon, I dyno'd it in February it made 480/482. The only thing different to the car was a 3.73 gear was put in place of some 4.30 gears, and the long tubes were installed. The car made 503/507 on the first pull. We let it sit a couple of minutes and on the 2nd pull it made 507/520. Needless to say I was pretty damn happy. I compared dyno logs to when I was there in February and it picked up 27hp and 38tq. I looked at the logs and compared and it actually picked up over 25 hp at certain rpms.
Im definately pleased with the long tubes performance and cant say enough about the sound. Im still working on getting some video of the car to show, lol. :beer:
Was this drive up and dyno or did they spend time retuning your car?
