Ok, it didnt have a missfire it was cos im a mong and didnt set the ignition timing right (was 1 tooth out on the phase sensor thingy) anyhoo that was fine, ran minted other than theres a new crack on the exhaust manifold thats a pain to come on and off, but can live with it for a few weeks I guess....
So car got strapped onto the rollers today, ran it up with bleed valve closed (no shonky EBC's here ) and it ran 1bar of boost and made 282@wheels@7K rpm everything looked minted, small oil leak from rocker gasket but not really a prob, so we decided to give the bleed valve a half turn, that took us upto 1.4 bar and produced 355@wheels (400ish@fly), Again no problems but were running out of fuel and my bottle was going so I 'think' im going to run it like that for the moment, at least for a couple of weeks to get some use out the car, then will get it back on the rollers, give it 2 bar and were 'expecting' to see 440ish@wheels (480@fly).

Couple of pics, exhaust mani paint seemed to last....it's only rated to 650degree's C





Engine bay looks untidy, will sort this in time though, got some bubbly rear arches to sort first
