actually, i've possibly gone a little backwards! ha ha!
i thought i'd have a giggle with a very low budget balancer, and a gunson colourtune, which as yet, has helped me about Zilch much! haha!
in fairness, i messed about with it for ten minites when i should have been helping kev load his car up, so i could do with a proper play with it later on.
on a similar note, having seen some diy 16v carb manifolds now on that ex Paul Sandiford race motor, i think i can see a reasonable way round the coolant circuit outlets, and if that works out, i see no reason why i can't recreate this whole item in stainless tube for the smoothest of bores on the inlet, and laser cut stainless flange plates top and bottom for accurate meeting faces and mounting. Possibly include an extended top flange plate to provide mounts for a heatshield and fixings for an isolated airbox.
ooh, don't i waffle!
it was nice to see how Paul had overcome certain things, including a similar air route to your own Bryan, but into quite a different idea of airbox, whilst not pretty, probably quite effective.
i'll knock a doodle up for Tom to cast his eyes on, but, you can possibly help me another small query please?
I was thrashing the idea out with Kev, and wondered why the area was so large within the currently avaliable manifolds, both the oe TB and made uop carb converters, for the coolant just to bounce around in?
to my knowledge, the links to the block opening from the stat housing are just that, pipework to move it all around, so Kev suggested that maybe there is the larger cavity for the coolant to stall for a moment to help with carb icing,
could this be case Bryan?, is a little heat transfer through the manifold metalwork important?
i know of carb icing though my bike experience again, Kawasaki's ZXR 750's were known to suffer with it if you had a european import model without the carb heater circuit that the official UK bikes had, but it had to be pretty bloomin cold to occur too!
