How Fast Would NASCAR Cars Go at Daytona without Restrictor Plates?

Doug Yates was guest on Dave Moody’s SiriusXM Speedway last week. He brought up a conversion you hear a lot in the week before Daytona and Talladega. Every 25 horsepower in the engine translates to about a 1 second decrease in lap times. Dave did the math: Removing the plates would increase the engine by 450 horsepower. Four hundred and fifty more horsepower equates to 18 seconds off the lap time, assuming all other things equal. That last part was a very important qualification. It will come back to haunt us in a moment.

Next-Gen Tires: Chewy on the Outside, Crunchy on the Inside

Listen to SiriusXM NASCAR radio, or peruse any of the racing websites and you will find a lot of theories about how races should be changed to make them ‘more exciting’.

With no series points on the line, that should have made for an exciting evening of hard driving and competitive racing.

Pit Road Speeding Explained

The black helicopters were out over Indy on Sunday, or so suggest some Juan Pablo (a.k.a. Juablo) fans. This happens every time someone leading a race (or contending for the lead) gets a pit road penalty. On This Week in NASCAR, Micheal Waltrip opined that if NASCAR caught you speeding,…

Behind the Science of Speed

The Science of Speed video series is now up at We did a press conference at Texas Motor Speedway Friday April 3rd afternoon announcing the series. If you told me three years ago I’d be sitting at a racetrack in-between a real racecar driver and an official from the…
