I do like the look of this but have a couple of queries.
In diagram part D there is a cutout which I assume the cooler welds into. Given the dimensions there my cooler is too broad for the space and to cut it broader would also
shorten the height of that particular piece. This will be fine. Get the manifold all tacked together and then modify the opening to suit. You could also cut the coolers end tank at a point where the opening will be closer to that of the manifold.
Another concern is having to remove the entire manifold to then remove the rocker cover. A bitch simply for tappet adjustment and the like. You can take this design further like one of the ones pictured earlier and flange the cooler to the manifold. Although removing the manifold is really not a hard job to do.
My thinking was to weld the correct size pipe into the plennum and join cooler to plennum via silicon hose, thus facilitating easy removal for access to rocker cover. The idea of the large opening is to help slow the air down into the head to reduce vacuum locks in the runners. If you reduce this down from cooler then increase into the manifold you get velocity changes which arent ideal. If you are set on this method then it will need to be a 4" connection.
The other matter is, how easy is it to roll the large section A down and around sections B? There should be a template on one of those drawings which you bend the described peice to then tack into place. You can just print out the reference peice and use a bit of cardboard to bend the plate to.
Given that it is 4mm aluminium is it easily acheivable by tacking / heating / clamping / tacking and repeat? Use a press if you can and get to bend as close as possible prior to tacking. Being 4mm it will be an extensive exercise trying to tack, heat and bend.
The upshot is I like the look of the unit, far better than I had in mind, and will run with it if It can be done without the cutout in part D.
Perhaps I can simply weld in a piece of plate when it hits the ground here?
I will put it to my brains trust today and get back to you. When do you intend to place your order? Will fit in with you if I can get a definitive answer this end. Order has already been placed I just asked them to cut a couple as I figure I could probably move them on if needed. The cost doesnt change much whether I get 1 or 5 cut.
Thanks mate!
