[O]ne suggestion drivers often make is to give them more horsepower.
“I think there’s a misconception that we could take the existing engines and just throw 200 horsepower in it,” said John Probst, NASCAR’s chief racing development officer, in response to a question from NBC Sports.
“We do have multiple-race engines today that we have to keep in mind. (More horsepower) is something that we are actively discussing, but, obviously, we don’t do that in a vacuum. We do that with the engine builders.
“But anybody that has been around, we’ve raced high horsepower and low downforce before and ended up at some point in time deciding to go away from that to get more entertaining racing. … I think we’re open to entertaining any horsepower gains that we can get with our current (engine) architecture, but anything beyond that is actually not something that can happen quickly.”
