NASCAR team owner Jack Roush talks possible Cup engine changes

3 Comments

With NASCAR indicating that it will make engine modifications for the Sprint Cup Series sometime in the future – which could involve a reduction in horsepower – one of the series’ most prominent team owners has an idea on how the sanctioning body should do it.

Jack Roush, owner of Roush Fenway Racing, told NASCAR.com that the modifications should include “a restriction on the intake side” that doesn’t involve restrictor plates, such as a reduction of the throttle bore size.

“[It is] straightforward and it is easily reversible if you decided that the quality of the racing was hurt by it,” Roush said. “If they want to take 100 horsepower off, reduce horsepower significantly, the least expensive and most palatable way to do that is with a restriction on the intake side.”

Roush also hoped that NASCAR would take the costs incurred upon the teams into account as they go about making the changes, saying that his and other teams can only afford to change so much at a time.

However, Roush feels like the sanctioning body could ultimately wind up simply reducing the RPM on the engine and add a requirement that engines must be used for two races apiece.

“By reducing the RPM, you reduce the power available for the car without changing its restriction or changing its displacement,” he said. “By making the requirement that an engine be run twice before it was subject to rebuild, we would have that opportunity to reduce costs to the teams.”

NASCAR CEO Brian France first indicated earlier this month that engine changes would come sometime within the next two seasons.

Shortly afterwards, Dale Earnhardt Jr. declared that a horsepower drop was inevitable and also, his hope that the engine would be smaller to preserve throttle response from the cockpit.

Supercross points leader Eli Tomac finds silver linings in interruption

Though his Monster Energy AMA Supercross championship charge was put on hold, the novel coronavirus (COVID-19) pandemic had a silver lining for Eli Tomac.

Off the road while the season was postponed for nearly three months, the points leader was able to be present as his girlfriend, Jessica, gave birth to their daughter, Lev, on April 26

“A huge blessing for us there,” Tomac told host Mike Tirico during a “Lunch Talk Live” interview (click on the video above) in which he also joked about becoming a pro at busting off diaper changes. “That was one good blessing for us as we had our daughter on a Sunday, that would have been on a travel day coming back from the race in Las Vegas.

“That was probably the only positive out of all this mess was being able to be there for the birth.”

But there also could be more good fortune for Tomac as the series resumes Sunday at Salt Lake City, Utah (3-4 p.m. ET on NBCSN, 4-6 p.m. on NBC).

The final seven events will be held over 22 days in Rice-Eccles Stadium, which sits at just over 4,000 feet.

The elevation could favor Tomac, who was born and lives in Colorado and is accustomed to riding and training at altitude, which is a departure for many Supercross riders (many of whom hail from California and Florida).

“That’s going to be the test for us,” said the Kawasaki rider, who five of the first 10 races this season. “We’re at elevation in Salt Lake, so when you’re on a motorcycle, you have a little bit of a loss of power. That’s just what happens when you come up in elevation. And a lot of guys train at sea level, and we’re at 4,000 to 5,000 feet, so cardio-wise, we’ll be pushed to the limit.

“Most of our races are Saturday nights and back to back weeks, but this go around it’s Sunday and Wednesday, so recovery is going to be key.”

Supercross will race Sunday and Wednesday for the next three weeks, capping the season with the June 21 finale, which also will be shown on NBCSN from 3-4:30 p.m. ET and NBC from 4:30-6 p.m. ET.

Tomac, who holds a three-point lead over Ken Roczen (who also recently visited “Lunch Talk Live”), told Tirico he had been riding for 90 minutes Thursday morning on a track outside Salt Lake City.

“Most of us we can rely on our past riding pretty well,” Tomac said. “The question is if you can go the distance. That’s what a lot of guys have to train on is going the distance. We go 20 minutes plus a lap. That’s what you’ve got to keep sharp is your general muscles. Within two to three days, your brain starts warming up more if you take a few weeks off the motorcycle.”

Here is the schedule and TV information for the rest of the season:

  • Sunday, May 31 (3-4 p.m. ET, NBCSN; 4-6 p.m. ET, NBC);
  • Wednesday, June 3 ( 10:00 pm – 1:00 am ET, NBCSN);
  • Sunday, June 7 (5-8:00 p.m. ET, NBCSN);
  • Wednesday, June 10 (7–10 p.m. ET, NBCSN);
  • Sunday, June 14 (7-10 p.m. ET, NBCSN);
  • Wednesday, June 17 (7-10 p.m. ET, NBCSN);
