First of all, I used pre-preg CF and it’s a great improvement than CF and resin!
I made two carton wings useful to create a separation plane (see pic above).
Then I attached on the body of the gummy manifold some detaching tape.
Using 4 x 0.4mm pre-preg CF layers, I made the external mould.
Then, internal and external vacuum bag, oven 70° Celsius for 5 hours, 6 holes on the wings for guide dowels and the mould is done.
Now, after painting with detaching varnish, it’s time to laminate the manifold on the two halves, having care of let the CF longer in one part than the other one (in order to close the gap between the two sides).
After all, join the two halves, internal and external vacuum bag, oven 120° Celsius (no more original rubber manifold inside to be protected at only 70°) for 5 hours in autoclave and the job will done.
Note that I don’t want to fix it directly in the car but I think to cut it shorter than the original in order to use few cm silicon hoses.
