I got a 12.9 on my nova, @103 mph, I only went flat out in first and second though, then just cruised through the other gears as I had a lean spot, until that spot I was ahead of Rob though, my 330ft was 5.37 and IIRC his was 5.5something.
that's good news mate
will you be writing it up for a mag then or was this purely in the intrests of arsing about

Found out in a quite dramatic way, the fuel caught fire, lol, luckily no major damage though, just a bit of loom to remake.
Will be interesting to see what mine can do when it gets a proper run.
this is the bit i can't understand mate, are you saying that the boost was backing up the inlet of the head and pushing out injector number one?
i've sen this happen before, but only in the case of mine and squeaks sierra's where the little 3mm plate used to hold the extra 2 injectors in situ that were stuck into the plemun isn't quite man enough to handle a bar of boost, but not heard of this happening to injectors fitted to the head
is it a simple re-engineering fix or back to the drawing board?
