Its time for our weekly Friday tour around the racing world. From hot laps to the main event, heres whats on our mind this week.

Hot Laps: Quotable

Juncos Hollinger IndyCar Series driver Sting Ray Robb had an interesting line when asked about his car during testing this week at Indianapolis Motor Speedway.

IMS is a crazy track to drive an Indy car around, Robb said. Youre either having the best time of your life, or youre scared out of your mind.

Qualifying: The Good Doctor

Famed neurosurgeon and consulting doctor to many of NASCARs biggest stars over the years, Dr. Jerry Petty died earlier this week. Hendrick Motorsports will run decals in his memory on all four of its Cup Series cars at Talladega (Ala.) Superspeedway this weekend. Petty was 90 years old.

First Heat: Hope & Pray

Its time for another Talladega (Ala.) Superspeedway wreckfest for the NASCAR Cup Series. Kyle Larson was asked during testing for the Indianapolis Motor Speedway, how he would change his mindset from Indy to Talladega.

Yeah, I dont know, Larson said. Just hope and pray you miss a wreck and can get to the front and stay up front.

That says it all about Talladega.

Second Heat: Supercars

Everyone knows Kyle Larson is among the most versatile drivers in the world. This week, he told the media he is interested in racing in an Australian Supercar event.

I dont know, one that kind of stands out to me and hopefully we can kind of put it together down the road would be Id like to run a Supercar, in particular in Adelaide, Larson said Wednesday at Indianapolis Motor Speedway. Its their finale. They have a sprint car track in the city, as well, so I could do both.

I would like to do that. Theres been some conversations. Well see where it kind of goes.

Third Heat: Kez & The King

Brad Keselowski recently spoke at length about having recently spent some time with seven-time NASCAR Cup Series champion Richard Petty during a trip to Washington, D.C.

The 2012 Cup Series champion, who also called Petty the greatest race car driver that ever lived, closed his remarks by encouraging others to stride to do things theyve never done before.

What are the things that 10-20 years from now youre gonna say, I wish I would have taken advantage of that opportunity and regret I didnt do it, Keselowski said. Richard was one of them for me and, given what I know about this room, probably the same. Hes got so many amazing stories and has lived the fullest of lives. Hes lived 20 peoples lives.

Dash: Driver Shopping

After only three races, Shark Racing parted ways with veteran sprint car racer Cale Thomas, and after a few days of shopping for a driver, announced Ashton Torgerson will pilot the No. 1a sprint car for three races this weekend in Pennsylvania. Torgerson, 18, is from Oregon and has 23 410 winged sprint car races on his résumé.

B Main: Missed Opportunity

Everything set up perfectly for last weekends NASCAR Xfinity Series race to be a huge home run for NASCAR and Rockingham (N.C.) Speedway.

Instead, it was a rotten egg on Easter weekend.

A sold-out crowd, a stellar field, 80-degree April day and a perfect television window on a holiday weekend were an ideal set up.

However, there were 14 caution flags for 83 of the 250 laps and the race took nearly three hours (two hours, 59 minutes and 38 seconds) to complete. But the capper was when fans in attendance and watching on television learned several hours later, or the next morning, that race winner Jesse Love had been disqualified.

Feature: Two Series

My opinions continue to change regarding the presence of two national touring series for sprint car racing. When High Limit Racing came along, I firmly believed it would fractionalize the sport of winged sprint car racing as it had in the past when the National Sprint Tour and USA challenged the World of Outlaws.

It would appear the opposite may be happening.

Last weeks Outlaw race on an off weekend for High Limit drew 62 cars to Knoxville Raceway. Many good cars and drivers did not get to race, whereas on weekends where both series race, the majority of those drivers are on the track, getting better, and making a few bucks.

I firmly believe that there need to be five to eight weekends a year where everyone in sprint car racing races together for big money. There are about five such events now.

Other than that, the more races, the more exposure in different places for the sport, and the more opportunity for racers to race and fans to watch the cars they love.

Regional tours including the NARC 410 Sprints, the POWRi 410 Sprints, IRA sprint cars and the All Stars are also having positive impacts on the winged sprint car scene.

Theres a lot to follow.
