The final article with my home built 2.1 Pinto where Graham Bahr (Penguin motors) did a final comparison, the journey to get this far was very difficult as 1 set of bike carbs were fitted with a dynojet kit and the diaphragms had shrunk slightly, still perseverance paid off in the end.
I found 2 very old Classic Ford magazines from Summer 2009 & September 2009 where Classic Ford build a project 2.1 Pinto and was the inspiration for my build some years later. I beat their dyno figures by some margin but Graham said my Pinto head (ported, big inlets standard exhaust) could have been better.
