Yes there is a member here(Rise of the Phoenix) that runs them...not sure what numbers he made or if he has any track times though.

I talked to Phil recently about the two, and he said that the price of Darts went up so he's changing the price on those to somethine like $24xx. At that point, doesn't make much sense to compare the two as they are pretty far apart in price. From the other long thread on the 223s it came out that Phil mentioned those should be good for 10-15hp over the 243s. If that kinda hp is worth close to a G to you then go with the Darts instead.
