Engine torque specs:
The following factory torque specs are meant for stock bolts torqued with light engine oil applied to the threads and the underside of the bolt head. Other lubes, like moly, offer reduced friction and increased bolt tension, which will affect the torque figure.

Aftermarket performance bolts (ie: ARP bolts) may come with their own recommended torque specifications.

Note that some specifications are in inch-pounds rather than foot-pounds.

Common electrical formulas:
W=watts, V=volts, R=resistance, kW=kiloWatt, I=amps

amps = W/V
amps = V/R
amps = kW(1000)/V
amps = sqRoot of W/R

watts = v^2/R
watts = R(I^2)
watts = VI

kW = VI/1000
