How to determine the torque of a bolt?
The wrong way, asserts Archer, is to pick a number off a standard engineering table or to rely solely on the classic equation, T = KDP, in which T is the target tightening torque; K is the coefficient of friction, or nut factor; D is the nominal diameter of the bolt; and P is the desired tensile load on the bolt.
How do you check the torque on a car wheel?
One way to check is to torque the bolt as you normally would dry then draw a line across the bolt where it meets on the wheel. Take it off then torque that bolt again with lube finding the amount of torque needed to line it up as it was dry.
When does engine torque reach its peak value?
It also means that the engine can move the vehicle quickly from stand-still, pull heavier loads or climb a slope relatively easily as the case may be without revving hard. The engine torque reaches its peak value at a speed where it is most efficient.
Which is the correct formula for engine torque?
What is Engine Torque? Torque, in simple terms, is ‘ Twisting or Turning Force ’. It is the tendency of a force to rotate an object about an axis. In automotive terms, it is the measure of rotational effort applied on engine crankshaft by the piston. Torque= Force x Distance.
Why do we need a torque specification for a TTY bolt?
This torque specification applies the proper clamp load to the joint while accounting for friction provided by the threads and the underside of the bolt head. Today’s engines require higher clamping forces (due to increased combustion pressure) which cannot be achieved with conventional small diameter bolts normally found in these engines.

How much torque do you need on iron block engine?
Westech’s Steve Brule was torquing the head bolts on an iron block LS 6.0L engine that had just received a new set of heads. We were using ARP head studs and the torque spec called for 70 lb-ft of torque. But something was definitely not right and Steve could feel it in the torque wrench.
