Couldn't find any specifics on Larry's Ghia,but I found this:
RSR Aero-horsepower Calculator-RB Racing
It's at the end of the 'document.'
Plug in drag coefficient
Frontal area
Weight
Speed
and hit the button,for
required horsepower
and aero horsepower loss is also provided
-------------------------------------------------------------------------
I did it for Spirit and it gave me 128-mph,at a discounted 147.17 horsepower.
It's out ahead of nothing
--------------------------------------------------------------------------
I threw some numbers in for Gumby's Dodge:
Cd 0.45
36.9 sq-ft
4,000-lbs
130-mph
= 298.82-horsepower (close to my Mini Cooper-based estimate)
-------------------------------------------------------------------------
With same specs and 150-mph
= 453.64-horsepower
------------------------------------------------------------------------
If 'Tonto' was slicked down to Spirit's 2012 drag coefficient he'd need only
281.4-horsepower for 150-mph.But they'd only let him do it for time,not a record.
