How Does a Rat Rod Attempt?
Introduction
A rat rod is a specialized type of drag-racing or street decalescent rod that has the largest potential engine in the smallest potential oppose. The back site of the vehicle is unnaturally Broad and hovering, whereas the front is all told limited and narrow, with petty tires. As a aftereffect, the comp's shape resembles the rat rod's diminutive, furry namesake.
Wheelie bars can be used to arrest wheel lift before it becomes dangerous, but these bars can and do fail.
Brakes & Tires
The only thing more important than the power-to-weight ratio is the braking ability of the rat rod.Most rat rods end custom racing transmissions. Public choices comprise a Turbo 350 Chevrolet automatic transmission and the older Powerglide two-speed automatic transmission, nevertheless some carry publication four- or five-speed transmissions. All rat rods must keep a Rough ride shaft, owing to the forces applied to it are far in excess of anything a works drive shaft would encounter.
Rat rods acquire their astonishing effectiveness from a aspect common as the power-to-weight ratio. The besides authority an engine produces, compared to the weight it has to push--in this occasion the car--the faster it can accelerate. On account of rat rods are typically small cars with tremendously oversized engines, the possible for velocity is extravagant.
Wheel Lifting
Many rat rods that are built on weaker frames action a instance admitted as wheel-lifting. The front rotate contradiction to the rotational torque--typically the Chauffeur's side front wheel--can lift itself off the ground. This is because the powerful torque applied to the frame is more than it can absorb; as a result, it flexes or twists slightly. Sometimes the twisting is not so slight and can result in frame damage. To prevent wheel lift, hot rod builders must exercise care when choosing a frame and deciding on engine placement.
The idea behind proper engine placement is to put the engine far enough back in the body to maximize power transfer to the rear wheels, while leaving enough weight in the front of the car to keep it grounded under all but extreme acceleration.
Design
Most rat rods annex older protest styles (such as the 1932 Ford Roadster) that acquire had the early engine, suspension, rear borderline, and other parts removed and replaced with racing-oriented parts, such as a low-geared quick-change differential. A extensive block racing Engine, occasionally with nitrous oxide, a supercharger, or both, is normally installed for enhanced horsepower and performance.A car that goes very fast must also be able to stop very fast. Unfortunately, most of the braking power (approximately two-thirds) comes from the front tires. This is because the weight of the vehicle slams the front end down when braking, enhancing the stopping power of the front brakes. This action takes weight off of the rear wheels, which makes them contribute less to stopping ability. As most rat rods have special undersized tires in the front, their braking ability is usually diminished. For this reason, a rat rod builder must exercise care when selecting brakes and tires.
