Just thought I'd share a few things I've been working on recently.
First up is an exhaust manifold with the turbo flange an additional 30mm away from the engine, but in the same orientation to aid clearance against the engine / bell housing when fitting large a turbo.
CAD design, jig and tacked together part.
I've also made the jig to suit standard exhausts.
I plan to put a brace inbetween the exhaust flange and the turbo flange to help support the turbo and so reduce the risk of cracking
The jig has a small hole in the turbo flange mount so I can purge the exhaust when fully welding it.
The manifold will also have a external wastegate with the pipe coming off the side above the turbo flange, which I'll cut in after
I've also drawn up all parts including a jig for a 3" elbow and started looking at the flow through them.
