Graham pop down and see me mate, we have taken on a Cosworth specialist and you can have a chat with him. We have an escort cosworth on the dyno we were mapping today and it made 544bhp at the flywheel. Our cosworth guy also owns an ex-WRC escort cosworth, it's here too At the moment we also have a Fiesta being prep'd for a magazine, a Cosworth powered combi and a mk2 Fiesta with a cossie lump too.
And I have to say, I'd definitely have the one on the dyno - very nice But then I am an 80's boy Although I'd definitely have a smaller turbo, good grief is it laggy !!!
