The NHRA continues to research ways to reduce horsepower for their professional nitro divisions.

NHRA has worked earlier in the season with Tim Wilkerson Racing and on the day after the NHRA Las Vegas Nationals at The Strip at Las Vegas Motor Speedway, expanded their data gathering program to Cruz Pedregon Racing.

The NHRA continues to research ways to reduce horsepower for their professional nitro divisions.

NHRA has worked earlier in the season with Tim Wilkerson Racing and on the day after the NHRA Las Vegas Nationals at The Strip at Las Vegas Motor Speedway, expanded their data gathering program to Cruz Pedregon Racing.

Pedregon’s team tested a combination comprised of a single magneto, one less clutch disc and a smaller fuel pump.  Currently, nitromethane race vehicles employ two magnetos in their engine set-ups.  Overall, the test was encouraging, although further testing will continue in the weeks and months ahead.    NHRA’s Dan Olson, Pedregon, and his crew chief Rahn Tobler worked together on tune-up changes and strategies between each test run. 

“I was very encouraged by the test,” Pedregon said.  “We obtained some good data that will give us a great starting point for further tests.  We were pleased that NHRA allowed us to participate and Dan Olson, Rahn and the entire team worked hard to yield some great results.”

NHRA will work with Cruz Pedregon Racing to schedule more testing during the off-season.  In addition, NHRA will continue to work with Tim Wilkerson and his team on the combination tested earlier in the  season which included decreasing displacement, use of a smaller capacity fuel pump, decrease in percentage overdrive in the blower, a change on the rear-end gear ratios, and the use of 90 percent nitromethane.

NHRA reiterated that this is strictly a testing and research project at this point.  It remains too early in the process to discuss any implementation plans or dates.  Once any decision is finalized, NHRA will give ample time for teams to adjust accordingly.   There is no completion date scheduled for the research/testing phase of this project.
