>At 4800 rpm the car showed 232 rear wheel horsepower and 415 lbs torque.

It's easy enough to check since (horse)power is the rate of producing
torque. The governing equations is:

HP = (TQ*2.0*PI*RPM)/33000

where:

TQ = torque in ft-lbs
HP = power in horsepower
RPM = engine speed in revolutions per minute
PI = the mathematical constant PI (approximately 3.141592654)
Note: 33000 = conversion factor (550 ft-lbs/sec * 60 sec/min)

Plugging in numbers for 4800 RPM and 415 ft-lbs of torque:

HP = (415*2*PI*4800)/33000
= 379.3

That doesn't match the number you were provided, so someone has made
a mistake. In general, the torque and power peaks do not occur
simultaneously. Typically peak torque will occur at a lower RPM
than peak HP will.
