Dirt Brandon Pesz points PJS Racing in new direction By Ian Tocher Y es, those were three distinct shift changes you heard when all three of the four PJS (Pesz-Jones-Sitton) Rac- ing entries covered the eighth mile during the U.S. Street Nationals at Bradenton Motorsports Park in late January. Father-and-son teammates Jeff and Justin Jones were running a pair of Larry Jeffers-built C7 Cor- vettes in Pro Mod, while Jeff Sitton’s Bickel-built 2018 Camaro was outfitted with drag radials for Radials vs. the World action. All three cars were tuned by Brandon Pesz, who will join the trio with 22 | D r a g I l l u s t r a t e d | DragIllustrated.com his Garrett-built ’53 Corvette later this season, mak- ing the jump into the Radial vs. the World waters. Some observers during pre-race testing at the historic south-Florida strip suspected there were five-speed transmissions in use, similar to what Jim and Jon Salemi have experimented with on Melanie Salemi’s PDRA Pro Boost entry. Pesz, however, says no. “Well, it is a four-speed with a lock-up, so when that lock-up kicks in it might sound like a fourth gear change, but it’s definitely a four-speed,” he insists. “This is our own stuff. Just something we’re trying out and it’s working pretty good so far. I put it together, but it’s actually a Lenco transmission with four special gear sets and then it’s got a Ty- Drive in front of it.” Pesz explains the advantage of adding a gear change, especially for roots-blown entries like Sit- ton’s and Pesz’s or screw-blown beasts like the Jones- driven Corvettes, is the ability to keep the super- charger wound up throughout each shift transition. “You’re RPM-dependent on a blower motor be- cause the faster the blower turns the more boost it makes, so with the four-speed you have just small drops each time it makes the gear change. So say it shifts at 10-thousand (RPM) and it only drops to 92-hundred; whereas, in a two-or three- speed it might drop to 85-hundred or so. The four- speed keeps the blower turning faster so the boost stays up, too, and that’s where you’re making your power,” he says. After Pesz and Jeff Jones teamed up the last couple of years, Sitton joined them late last year and all four cars are now housed under one roof Issue 142 Strength in Numbers
