Dyno testing turbo cars

[Flanagan, Steve]

Yeah, but making almost 1800 HP with a small block 302 - single turbo does.

anyway:  

agreed, but these products described use the collected data to determine the
torque and HP curves for the engine and that is useful info to determine
where to shift the car.  I already have data but would love to try to plot
out my torque and hp curves.

any help would be appreciated.

Calculated HP,
Never won anything.
