As for who done it first i'm not sure, the first one I made was in sep 99 along with an external wastegate set up using an ex cosworth F1 turbo,this was state of the art in the cossie world back then as I should have been running a T4
anyway while mapping with the first inlet and monitoring EGT it was clear that the inlet wasn't perfect so I went from box design on to the rounded tapered design which was made in early 2000, this proved to work good and I have sinced reproduce my manifolds to this design, I have not had them flow tested but in the past 6yrs there never been a fault from a result in using my inlets. I've alway ran one, Brom and SEAN B had them, Steve Scott Has one on his Fiesta after blowing a copy one apart then the same 'Coff' back resulting in blowing the ISCV apart and not effecting my inlet that is still fine to this day, The actual one made in 2000(first good design) is on Comedy Dans saph cossie that runs around 430RWHP andf that inlet is 6 yrs old.

Back to who was first with the idea I'm not even sure there the same but there BOTH good weather its mine or from Mike, just dont risk your engine to save a few hundred quid cus ya mate can work a welder, theres more to it than that!!

Look out for Performance Ford mag soon with my latest one off ST170 turbo fabricate inlet
