I had the day off so I went to a performance shop with a new all wheel drive Mustang dyno.
It was low 80's and raining. First pull (3rd gear) only yielded 248 hp and 228 torque. Man o man sheeesh. Well after trying to do better we decided to do a 1/4 mile run. More problems. The traction control was kicking in because the tires were loosing traction on the rollers. He just couldn't stop it from happening. Then I pulled fuse 17 and 18. Then the dyno showed a 13.9 at 106.9158. That is the mph I get at the track with a 13 flat. The problem, no fat guys at the shop to sit in the trunk and loosing traction on the rollers. But the dyno operator pulled up the hp and tqe from the 1/4 mile pull which was 291 hp and 283 torque. AFR was 11.4. Still not what I thought I'd get. Now I understand all the back and forth about dynos! It's not so simple as strapping down and reading the printout. So who wants to guess what I really have considering it's a Mustang? I won't be torturing myself on a dyno again for a long time.
