yeah i have mate, im not a "daddy bought me a fast car" boy or a "if i put a max power sticker on, it will go faster" .ive grown up around fast cars, and been in the trade for a fair while. ive had a few , just never a standard cosworth, thats why it just seems too slow! the last one i had was a crystal blue e reg with 200 block, polished crank, low comp, big injectors, t4 turbo etc, did a couple of bits and bobs to it but thanks to a pillock ruining it, instead of painting it put me off so looked elsewere to the m5, skyline, evo group for my thrills, just isnt the same. should be still on the restoration forum somewhere. ive always bought them at a good spec allready needing a little tlc and never built one up from a standard engine,just wanted some advice before i did what i thought was right at the time, i would rather ask advice than blow my engine up because i was too stuburn to learn something new, just trying to find my feet back in the ford world again.
anyways anough of the chest puffin, i did what you advised and took a look at the dump valve, turns out there was a split in the diaphram, gave her a full service, fitted a boost gauge and now shes kicking in strong at 4k and running at 0.7 bar....so thankyou for the advice, its not something i would of looked at!
