Tuhia he tomokanga mō tēnei wāhanga - I te tīmatanga o te tekau tau 1970, ka tūtaki te kaihautū whakataetae a Yip ki a Sid Taylor, ā, ka whakaae ki te tautoko i a Vern Schuppan i te Formula 5000. Na tenei i arahi ai a Yip ki te tautoko i a Schuppan i te Formula One me Ensign i te 1974. I whai ake ko te whakauru atu ki Amerika me Schuppan, katahi ka tautoko i a Alan Jones i te raupapa US F5000 i te 1976. I Ahitereiria, i wikitoria a Schuppan i te Rothmans International Series mo Yip e taraiwa ana i te Lola T332-Chevrolet i te 1976. I taua tau i whakatuhia e Yip a Theodore Racing. I whakahaerehia e Taylor, a, i whakauruhia he Tohu mo Patrick Tambay i te F1. Whai muri i te tau uaua i te tau 1977, ka tono a Yip ki a Ron Tauranac kia hanga i tetahi motuka F1. Ko te waka, i huaina ko te Theodore TR1, he uaua, a, kaore a Eddie Cheever i eke ki Brazil me Argentina, engari i muri mai ka riro a Keke Rosberg, ka wikitoria i te International Trophy i Silverstone i te wa makariri, ahakoa kotahi noa iho tana tohu mo te GP i Awherika ki te Tonga
He aha? I whakarerea te motokā i waenganui o te tau. I te US, i tautoko a Yip i te kapa Eagle a Dan Gurney.
