Do these numbers seem right? Torque numbers low?
Do these numbers seem right? Torque numbers low? In the past at same shop with same mustang dyno, just headers and cutout I put down 330rwhp/312rwtq
Now.. I went back today with mods in sig on mail order tune and stock injectors and put down 383rwhp/331rwtq
Now heres the odd questions.. why is my torque so low, why can I hang with and in most cases beat people with 450rwhp. Example being a friend who i looked at his dyno graph down there, same dyno, put down 480rwhp.. yet 20-150mph were dead even, neither of us get ahead. The shop owner mentioned that the 4.10 gears may somehow be skewing the numbers but I still find that a little odd.

50 views and no comments? Seriously you gotta be blind to not see something is wrong with my torque ahaah
HP = TQ * RPM / 5252 Based off this calculation.. shouldn't I be hitting also around 410rwhp at 6500 rpms?

I'll agree it's odd, I have no explanation of why the torque is so low, or why you run even with a car with 100 rwhp more than you. Unless the other car is 4500 lbs.
Try another dyno if the numbers bother you. Or you could just tell people its a 380 hp car and wax their asses.

This is what boggles my mind. Hp I can accept a 380-390 range being on a mail tune and stock injectors for a mustang dyno. But the torque is just plain nonsense. Most of the cars I run with are between 4-500rwhp depending on weight etc. So it makes me so worried that either I think something may be wrong with my car.. or something is up with the dyno and I should just grab a run on a different dyno to be safe it isn't my car. I just don't understand picking up about 15rwtq from headers, how on earth that could even be realistic.

Verdad Gallardo 28's I believe due to being a 1998 fbody. I was told a while back by a local tuner that my injectors were trying to run almost 120% duty up top. I'm not sure if that is killing it alot or not but it would make me feel better if that was a big reason
