I am sorry but I don't know if you are saying that that the 5252 rpm cross over can be changed ? Maybe I am reading it wrong.
I have owned a few motorcycle dynos in the past and had many of my cars on different dynos in my life.
I do know that the cross point has to be that 5252 ,,and if not something is wrong in the calculations to get the right HP/TQ..
It is explained in this linkhttp://www.onpointdyno.com/?p=3306

Look at the Vertical Axis & curves on the Mustang dyno sheet, the scaling is different for the HP curve (Red) and TQ curve (Blue). Example: 902 WHP & 767 WTQ are both at the same height on the Vertical Axis.

Quote: Its all about where the scaling is set to. Mustangs give you the ability to rescale the y axis as you prefer. For instance if identical scales are forced they will cross at 5252, like on the dynojet. Where as on the mustangs y axis it shows peak torq and peak hp on y axis, not 0 to 1100 for instance. However identical scales can be forced, its just not default setting.
This might help point out what he's referring to.


The Mustang software allows you to, and actually defaults to using different scales along the Y/Vertical axis, but still fit into the same size chart. Looking at the left columns you'll see:
  • TQ Scale: min=-74; max=860
  • HP Scale: min=-93; max=113
  • TQ Scale: increases each marker at +94
  • HP Scale: increases each marker at +111

The numbers are the same, it is just another perspective to read. Unless the scales are set to identical you won't see the 5252 crossover. That doesn't change anything on the car, just how you're looking at the graph.

The cross over doesn't change and if you look at 5252 on both hp and Tq curves it will be the same number. It's not plotted that way because the Y axis was not scaled the same for hp and Tq when that picture was taken.

Here is another dyno from Undercover from when I had 6262s and hp and Tq Y axis were scaled close together.

Great job...I figure about the same as you do, low-mid 9's once you get everything sorted with that MPH and HP

Congrats Mark! Looks like the spool bus is a 9 Sec car! Killer trap speed.
