It feels like two lifetimes ago but I was a race car fabricator/engineer as a young guy, six years in motorsports, including Indycar. As fifty gets closer I, like many, seem drawn to revisit what was fun decades before. That's a big part of the reason for turboing a bike that was already near perfection. Anyway, back to the build.
A turbo inlet flange was cut from 3/8 plate. Unfortunately its mild steel so it will need some coating. I didn't want to loose the weekend to get stainless.
The header was extended back towards the turbo.
This piece will get sectioned later for a slip joint. On a V motor there must be a way to separate the pipes.
Here the tire clearance is being checked with a straight edge. I really cut it close by tucking the turbo in this tight. Its not as bad as looks here though. The straightedge is leaning well forward of the closest point.
