For three races now, the NHRA tech department has been gathering data on the centrifugal supercharger as a possible fourth power adder in the Pro Modified division.
On Friday and Saturday, racers John Strickland and Lester Johnson made laps with respectable results.
“John ended up running within four numbers of the leaders each round,” Kevin Rivenbark, a racer who has participated in the testing, explained. “In the last run John went a 5.791, and earlier went a 5.77. There’s a lot of potential, just need to get in more runs.”
Rivenbark said he believes working in the centrifugal supercharger into a challenging three power adder class will not be as difficult as some might think.
“Just a matter of working in the transmission, converter, and the rear gear,” Rivenbark said.
Stevie “Fast” Jackson spent much of Monday at the NHRA Carolina Nationals, multi-tasking, and in the end, succeeded on all counts. He clinched the NHRA Pro Mod championship and the event title. – https://t.co/nRWIFpAP5Q pic.twitter.com/lelP5JhjFY
