It's all about the total work done by the engine. A one point HP rating don't do that.
This is taking silly to the extreme. The two cars are within 100lbs of each other. One car has 210hp, and the other 180hp. The one that has 210hp is going to be faster unless something really weird is going on. In reality, tests of the two cars show that the one with the extra 30hp was faster. C&D got a 15.3s 1/4 mile time when they tested it. Various publications list the Saturn at anywhere from 16.0s to 16.5s for 1/4mi. So, real-world testing shows what everybody knows...a car with more peak power is going to be faster through the 1/4mi than a similar weight car with less power. Shocking news to some.
Then we get someone posting here that their Saturn can run 14.9s for 1/4mi. That conflicts with common sense, published figures, and reasonable comparisons to similar weight vehicles. There is no way that Saturn is running in the 14s without a major addition of power somehow....end of story. Slight changes in final drive ratio because of a different tire aspect ration simply isn't going to get it done.
Using an online 1/4mi calculator showed 15.6s for the Mustang and 16.25s for the Saturn....pretty close to what actual testing showed. According to the same site, the Saturn would need about 230hp to get to 14.9s. Tire ratio isn't going to make up for a 50hp shortfall.
