After the Galgo IMSA GTO was retired in 1986, ADM followed next year with a race prototype, the Galgo GTP. It was powered by the same Barracuda V8 as the road ongoing version, but bored to almost 6.2L of displacement. It was also the last GTP car to use carburetors. It pushed around 650hp, able to reach 330km/h.

The galgo GTP ran from 1987 to late 1989 with mixed results in the IMSA championship. It ran in the 24 of le mans in 1988 where it managed to finalized, albeit in mid of the pack, given its awful fuel economy.
