The first clue is there's over 600 torque showing, which isn't possible.
At first I thought they were scaled differently but that wasn't quite right. Look at the axis labels, torque is being reported in nm not ft-lb
So if you do the math, 600 * .73, you get 438 ft lb, which would intersect...
Here's another way way of looking at your numbers
You said you did a 7.9 100-120 (62-124mph for the rest of us)
That means you'd do about a 9 second 60-130 which is about right for a full bolton Mustang on e85
A stock DH thats running really well will go 10.1 or so
You're only up about 5 in...
It's tuned so they both make the same amount of power according to the tuners....same engine except better rods/pistons (which don't matter at NA levels)
Nobody said they add power. They free up power. Which the dyno sees as more power.
More power to move the car instead of spinning around parts. Not sure why this is so hard to understand.
