Whakaotihia te rerenga e whai ake nei: I tiimata te PC1 i te 1974 Canadian Grand Prix me Donohue e tohu ana i te 24th ka mutu i te 12th. I wehe atu a Donohue i tana whakataetae kāinga me Penske i te whakataetae i muri mai
1974 United States Grand Prix i whakahaerehia i Watkins Glen i muri i te tohu 14th, kaore i taea te whakaoti i te whakataetae na te ngoikoretanga o te whakamutu o muri.
