I doubt that aerodynamics has much to do with 1/4mi times when
the car is travelling below 100mph.  But yes, aerodynamics does play
a role.

Hp is just a combination of RPM and torque in an equation with a constant
multiplier.

Like, I said, that equation is very rough.  But it is accurate enough to
give you some idea of how well your car will do in the 1/4mi.

Incidentally, a supercharged ram-air convertible Sunfire that Motor
Trend tested only did the 1/4mi in 15.1@91mph.  And that car had
197hp.

I am not sure why people don't think that a turbocharger is a brute
force way of making power.  I mean, shoving 24psi into a 2L engine to
produce 600hp, and getting the car down the track in 9 seconds isn't
brute force enough for you? :-)

Turbochargers are anything but modern technology.  I bet that they
predate your friend's 40 Ford ;-)
