If you take a look at Harris's Acrocanthosaurus reanalysis published in the
Bulletin 13 of New Mexico Museum of Natural History and Science at page 72
to 75 for the matrix and 54 to 55 for the cladogram you have a lot of
outgroups more conservative than Abelisauridae such as Torvosaurus,
Afrovenator, Eustreptospondylus, Piatnitzkysaurus etc...
