[53], The last race with the original restrictor plates was the 2019 Daytona 500; after that race, the cars moved to a variable-sized tapered spacer already used at all other tracks, with the exception that the spacer would have smaller holes than the ones used at the smaller tracks, to ensure speeds stay under 200MPH. The off-throttle time is what we want to see, and what the drivers want to see., NASCARs turnaroundfrom a low-horsepower, high-downforce package to the oppositemight seem sudden. (The 2010 Aaron's 499 had 88 lead changes, but the 88th the race-winning pass by Kevin Harvick was on the last lap of the third attempt at a green-white-checkered finish). Kudos to John Probst and Eric Jacuzzi for working together and working with us to get a good test together.. "The first year is going to be expensive. Contact them directly: caleb@thedrive.com.

Per Fox Sports' Bob Pockrass, this will drop horsepower from roughly 510 to around 450 and reduce speeds 7-10 mph. As a safety measure to reduce speeds at the two high-banked superspeedways (Daytona and Talladega), restrictor plates are used. The bottom graph shows how many points Elliott earned in each race. Buschs win at Talladega last week, his first at the 2.66-mile track in 15 years, gave the team a boost.

A key feature of the FR9 is its superior cooling system, which allows the engine to maintain maximum power at high operating temperatures. The following race at Talladega that year would be run with a smaller carburetor, however, NASCAR mandated the use of the restrictor plate at the end of the season. WebThis prompted NASCAR to cut horsepower to 550, this cut has been seen as a bad move by NASCAR, but whats considered too little horsepower for NASCAR? Do NASCAR Cars Need To Be The Same Shape?
