Fuel injection in NASCAR

The idea behind fuel injection
Fuel injection
Fuel injection is a system for admitting fuel into an internal combustion engine. It has become the primary fuel delivery system used in automotive petrol engines, having almost completely replaced carburetors in the late 1980s....

History

Back during the 1957 NASCAR Grand National season, the then-current president of NASCAR, Bill France, Sr., immediately banned fuel injection and superchargers from NASCAR before they could race due to the domination of the 1957 Chevrolet. The 1957 Chevrolet was one of the first fuel-injected vehicles to become mainstream in America and enough were sold to allow it into NASCAR competition due to homologation

The first race in NASCAR Sprint Cup Series history to use fuel injection will be the 2012 Daytona 500; which will take place on February 26. The first series of tests that were applied to the new fuel injection system began on the Thursday practice prior to the 2011 Quaker State 400

 was the fastest driver inside a fuel injection vehicle and Ford was the quickest vehicle. Stock car racing technology had fallen behind the technology used in vehicles that are mass produced for the general public. The reason behind this is that NASCAR didn't take advantage of fuel injection when fuel injected vehicles started to almost completely replace carbuetor-powered vehicles during the late 1980s.

Outside the NASCAR racing circuit, the American automobile manufacturers would make the final two models to run on carburetors: the 1990 Oldsmobile Custom Cruiser

s, however, will remain in the series for an indefinite period of time because major accidents at Daytona and Talladega made it necessary for a device to slow down the vehicles to half of their normal horsepower. Sprint Cup vehicles (powered using carburetors) can only go up to 185 mi/h at a typical Daytona 500 race while the NASCAR Camping World Truck Series pickup trucks can do up to 190 mi/h and don't require restrictor plates. The fuel-injected NASCAR Sprint Cup vehicles may run slightly faster than their predecessors; also making new challenges for the restrictor plate manufacturers.

Fuel injection allows a precise amount of fuel to suit the amount of air flowing through the engine; making it more efficient. Fuel injection is also used to regulate the horsepower
