I would be surprised if a female athlete turned into male athlete would beat a male. Males have more muscle mass by default.
There are some sports were technique and experience is quite more important than raw muscle. But I do imagine that will be hard to come to a case that a trans male athlete even with testosterone on the level of male will be able to compete to the point of being olympic champion or whatnot.
