Cause of multiple engine failures in Las Vegas Truck race revealed

Leave a comment

NASCAR and Ilmor Engineering announced Thursday the results of their investigation into multiple engine failures at the Sept. 13 Gander Outdoors Truck Series playoff race at Las Vegas Motor Speedway.

Five trucks – including three from ThorSport Racing – suffered engine failures during the race. ThorSport drivers Grant Enfinger, the regular-season champion, and Johnny Sauter were both eliminated from the playoffs after their engine failures. ThorSport teammate Matt Crafton also had engine failure but managed to advance to the second round of the playoffs, which begin October 12 at Talladega Superspeedway.

Ilmor’s NTI engine was introduced to the Truck Series before the 2018 as a cost-effective alternative to engines developed by teams and manufacturers. It is used by most teams.

Here are statements from both Ilmor Engineering President Paul Ray, as well as NASCAR:

Paul Ray: Ilmor Engineering is committed to our partnership with NASCAR and to the long-term development of the NT1 engine. To that end, following the issues experienced by a number of different teams and competitors during the Sept. 13 race at Las Vegas Motor Speedway, engines were returned to the NASCAR R&D Center for technical inspection and data review. The combination of the high engine load condition combined with the extreme weather conditions in Las Vegas resulted in some engines suffering severe detonation. Ilmor is taking new measures in engine calibration to ensure to this situation is corrected for all future races.

We deeply regret the impact that the engine issues created for our NASCAR Gander Outdoors Truck Series partners. We have requested every engine that raced at the Las Vegas event be returned to our technical facility in Plymouth, Michigan. All the engines will be disassembled and inspected by our highly experienced team. Any damage as a result of the Las Vegas event will be corrected and the engine returned to the race teams as soon as required.”

NASCAR: We commend Ilmor Engineering for their thorough review and the forthright way they’ve claimed ownership of the engine issues suffered by teams during the Sept. 13 race at Las Vegas Motor Speedway. The NT1 engine has played a vital role in the health of the NASCAR Gander Outdoors Truck Series and that’s been evident in the tremendous competition we’ve seen all season. We’re confident that will continue in the years ahead.”

Following the Las Vegas race, Enfinger told FS1, “It’s just a shame our season hopes come down to quality control on a spec part that we had nothing to do with. I definitely share our owner’s frustration with the parts.”

Sauter’s team tried to repair the issue and got him back on track, but he didn’t complete a full lap before the engine let go for good, ending his night.

Just inferior engines, I guess, I’m not sure,” Sauter told FS1. “It’s just disappointing that our season comes down to that. This is a fresh engine, obviously something’s wrong with it. … It’s just a shame … but if something happens and it’s out of your control, what are you going to do?”

LAS VEGAS (AP) — Kyle Busch extended his NASCAR Truck Series victory record to 57 in his hometown Friday night, leading 108 of 134 laps at Las Vegas Motor Speedway.

The reigning NASCAR Cup Series champion swept both stages and finished 5.958 seconds ahead of Johnny Sauter. Busch has won seven straight races in the series, including all five he entered last season.

Austin Hill was third, followed by defending series champion Matt Crafton and Ben Rhodes. Grrant Enfinger, who opened the season with an overtime victory at Daytona, did not finish after an accident with 43 laps to go.

Christian Eckes was right behind Busch in the opening two stages, but he finished 23rd after an early final-stage wreck.

Jimmie Johnson was the fastest driver in Friday’s second and final NASCAR Cup practice of the weekend at Las Vegas Motor Speedway.

Johnson and his Chevrolet were followed by five Fords.

Clint Bowyer, who was second-fastest in the first practice earlier in the day, was once again second-fast in the final session at 179.271 mph.

Aric Almirola, who was fastest in the first practice, was third-fastest in the final session at 179.170 mph.

Next goals for Daytona winner Denny Hamlin: double-digit wins, Cup crown

Leave a comment

There was a time when Denny Hamlin’s best memories of the Daytona 500 were to just go home relatively unscathed.

Consider this: In Hamlin’s first six appearances in the Great American Race, his highest finish was 17th.

But after a breakthrough 4th-place finish in 2012, he has become the best overall performer in the 500 among active drivers.

“I don’t know what it is, but I think I started studying more about superspeedway racing around that time because I had been so unsuccessful for a very long time,” Hamlin said Friday during a media session at Las Vegas Motor Speedway.

“We went a long time and I’ve won a lot of the Clashes and Duel races, but not many like Talladega – I think I have one win there – but it just seems like it’s that seven or eight years ago that the car came around and whatever techniques I use or I’ve adapted to this car have seemed to work.”

In the last seven editions of the 500, Hamlin has finished 2nd (2014), 4th (2015), 1st (2016), 17th (2017), 3rd (2018), 1st (2019) and 1st again this past Monday.

Do the math and that’s three wins – making him only the sixth driver in NASCAR history to win the 500 three or more times – and seven overall top-5 finishes in the last nine season openers.

Hamlin knew that getting his second 500 win in a row – both outcomes being the closest finishes in the race’s 62-year history – and third in the last five years was basically going to come down to a battle between him, Ryan Newman and Ryan Blaney.

With emphasis on Newman, that is, before he was involved in that horrific last lap crash on the front stretch heading toward the checkered flag.

“I pulled the block on (Newman) coming to the white (flag) and I stayed in front and I knew he was going to back up to (Blaney),” Hamlin said. “I was trying to back up myself, but once (Newman) was attached (to Blaney), I knew they were going to come with a run I could not stop.

“I just held my line because if I started going sideways, the next thing you know (Newman) starts moving sideways and (Blaney) is already hooked to him, so he’s probably going to push him sideways into me.

“I just wanted to hold a straight line to let them know hey, pass this way, and when I did I was able to back to (Blaney) and was able to unattach him from (Newman). When I slowed his momentum, that allowed me to really tuck in right behind him. I don’t know if he checked up to keep us attached but once we got attached, I knew we were going to have a run back on (Newman).

“I knew he was going to get there, I didn’t know what was going to happen when he did get there, but certainly it worked out in my favor. I thought I was going to get back around (Blaney) at the (finish) line if there was no crash, but I wasn’t sure I was going to get all the way back to (Newman). I knew those two were going to jostle and I was just hoping to be in the right place when it happened and I was.”

Not having any 500 wins of his own, Joe Gibbs Racing teammate Kyle Busch is envious of Hamlin’s three triumphs.

“Denny has really gotten way better ever since this car,” Busch said of Hamlin and how he’s adapted to the Gen 6 car in recent years. “He was always an aggressive plate racer, one that would make moves that you’re kind of, ‘Man, if he would just stay in line, I think this would turn out better.’

“He still does that today, but he’s making it work for himself, that not staying in line is better for Denny. I think since this car came though, he’s been a real good plate racer.

“He’s been fantastic at the game, he’s understood it, he’s made moves that I sometimes wouldn’t make that have worked, he’s able to pass a guy to get in line. … He’s very knowledgeable and skillful In making his moves and passes.”

Going forward from Daytona, Hamlin said his next goal is double-digit wins this season. If so, he’d become the first driver to earn 10 or more wins in a season since Jimmie Johnson did so in 2007 when the seven-time champ won 10 races.

“I’d be satisfied with that and then beyond that would be nice,” Hamlin said. “I think that the championship is an easy goal that anyone just throws out – win a championship, but that comes down to one race.

“If you can win a significant amount of races, it shows a bigger picture of your full year. If you make it to the Final Four, that’s a bigger picture of your entire year (Hamlin has reached the final four just twice since the format was introduced in 2014 — third that year and fourth last season). I think the championship – a successful year is making the Final Four. Anything after that is just whatever it is.

“Certainly we set lofty goals. I think everyone sets huge and lofty goals, but certainly we’re going to push ourselves to better what we did last year and it starts with Daytona and we’re able to repeat there so then let’s get a win now before we get to Texas to keep ourselves on pace or better from last year.”
