Recently, the Street Outlaws community has been abuzz with discussions sparked by Kye Kelley's latest YouTube video. In this video, he dives into the intricacies of testing his new car, shedding light on potential game-changing developments in the realm of screw blown combinations on No Prep Kings.

One of the key revelations from Kye Kelley's update is the introduction of new weight breaks for screw blown setups on NPK. According to his findings, competitors running their screw blown setups at 82% overdrive can now shave off a substantial 90 lbs from their base weight. This reduction alone marks a significant advantage in a sport where every pound counts towards performance.
Moreover, another weight break was quietly implemented midway through the season. This adjustment allows those opting for a higher 92% overdrive to trim 40 lbs from their base weight. However, for racers choosing to stick with the standard 98% overdrive, the base weight of 2825 lbs remains unchanged from the previous year.

For racers not utilizing lockups, an additional 50 lbs can be shed, bringing the weight down to 2775 lbs. Further reductions are possible for those running reduced overdrive settings. At 82% overdrive, racers can weigh in at approximately 2685 lbs, and those with pre-1979 built cars can drop an extra 25 lbs to reach 2660 lbs, albeit such lightweight configurations are rare, especially for screw blown cars.
The debate surrounding these weight breaks extends beyond mere numbers. Switching from 98% to 82% overdrive potentially sacrifices 3 to 4 lbs of boost, which translates to a considerable power reduction in the realm of screw blown setups. Nevertheless, history shows that even at lower overdrive settings, such as the 75% used in NH Pro Mod back in 2022, screw blowers can still deliver impressive performance. For instance, Stevie Fast achieved a remarkable 570 at 257 mph in the quarter-mile with a limited screw blown setup, proving that these engines retain their potency across varying overdrive levels.

The implications of these developments are profound. Kye Kelley's new build, coupled with the possibility of exploiting the new weight breaks, could usher in a new era of dominance in street outlaw racing. His meticulously crafted car, optimized for speed and agility, holds the potential to redefine what is achievable at reduced overdrive levels.
As the season progresses, all eyes will be on how racers adapt to these changes. Will more competitors follow in Kye Kelley's footsteps and explore the advantages of lighter weights at lower overdrive settings? Only time and the race track will reveal the true impact of these weight breaks on the competitive landscape of street outlaw racing.
