In NASCAR discussions recently, debate has centered on the current engine power limitations and calls for a boost. Many participants argue that 670 brake horsepower (bhp) no longer meets the demands of top-tier NASCAR racing, and Denny Hamlin shares this viewpoint. The driver advocates increasing the engine output to at least 750 bhp, while noting that 800 hp would be optimal, although he prefers to accept any change without prolonged dispute.
Background on NASCAR’s Engine Power Restrictions and Proposed Changes
Historically, NASCAR intentionally reduced engine horsepower to enhance race competitiveness and close the gap between leading teams like Joe Gibbs Racing and Trackhouse Racing. However, these measures have sometimes led to less exciting races. Consequently, there is current momentum toward allowing engines to produce more power, potentially raising the limit from 670 hp to 750 hp. Hamlin welcomes this potential adjustment.
During a recent episode of the Actions Detrimental podcast, Hamlin elaborated on his stance, favoring an 800 hp target but choosing not to press the issue aggressively. He urged acceptance of incremental improvements.
I think we need to just take whatever they’re willing to give us and shut up and move on. Because it will absolutely be better than 670, which we currently have,
Hamlin said.
Anticipated Effects of Increased Power on Racing Dynamics
Hamlin expressed that while more horsepower will enhance performance, the impact may be moderate, perhaps improving results by five to ten percent. He also expects additional power to increase tire degradation, thereby influencing race strategies. This change could affect how teams set up their cars and even influence decisions about driver selection.
Furthermore, Hamlin emphasized his hope that engine builders maintain economical modifications to the existing engine when increasing power, avoiding extensive complexity in upgrades.
Technical Insights from Hendrick Motorsports on Power Increase Feasibility
Supporting Hamlin’s position, Scott Maxim, Vice President of Hendrick Motorsports’ Powertrain Department, recently discussed the topic. Maxim explained that current-generation engines are capable of producing more than 670 hp; however, engineers utilize a tapered spacer to reduce power output. Modifying the size of this spacer could easily raise horsepower.
Maxim noted that his team has prior experience with this adjustment and regards the necessary changes as moderate rather than drastic. He expressed confidence that they possess a strong understanding of how to implement this power increase efficiently.
Potential Implications for NASCAR and Its Participants
An increase in engine power, even by a moderate margin, could revitalize NASCAR races by making cars faster and more demanding to drive, leading to strategic shifts for teams and drivers alike. Hamlin’s pragmatic approach reflects a desire to embrace improvements without overcomplicating the transition. With backing from both drivers and technical experts like Maxim, NASCAR’s possible move to uplift horsepower suggests a significant development in the sport’s competitive landscape.
