The NHRA kicked off its 2018 season with the Lucas Oil NHRA Winternationals two weeks ago. We gave you a recap of the top NHRA class winners here, but here’s a rundown of the Sportsman class winners. As the son of legendary NHRA announcer Dave McClelland, Kevin McClelland is no newbie to drag racing. In fact, his Super Gas victory at the Winternationals earned him his fifth national-event Wally. “This is really special,” McClelland said. “I won this race 21 years ago at my very first national event, and it’s been an awesome run.”
Upgrading a few bolt-ons at the same time makes sense. Here are some popular choices. (Note: In the links below, sort by year, make, and model to find the right part for your vehicle.) With stock pulleys, the blowers spin around 16,000 rpm at redline. Changing the pulley sizes can spin it faster and increase boost. The next step on the upgrade path is a pulley swap. The chart below will give you some idea of what to expect.
Upgrades are usually done in stages. Each level will provide more performance than the one before it. However, they will also be more involved and expensive. The first upgrade we recommend is tuning the computer. This involves changing the fuel and ignition curves to optimize performance. A good tune can gain up to 40 hp on a stock engine. (Any significant upgrade will require re-tuning the computer.)
The build took Edwards more than two years to complete, and he funded the entire build out of his own pocket. “This is a completely home-built project, no professionals involved,” Edwards said. “From the design and construction of the frame to the finished paint, it was all home-built.” The belly tank racer was built with strict adherence to the SCTA rule book, and Edwards intended to race his creation at the Utah Salt Flats Racing Association‘s World of Speed event in 2017.
