    NHRA allows PSI Screw blowers and IHRA only allows HH Rootes blowers. Probably around 500 HP difference (give or take a little)

    ihra tafc

    does anybody know why ihra only has the tafc using the roots, and doesn't have a tad class using the roots? looks like it would only make since to have both.
