The Turbo TR1 (part 5) - headers are the spaghetti of doom
Just like on a naturally aspirated engine the overally performance is vastly affected by how well thought out the exhaust header design is. On the TR1 it is (even more than on other bikes) a balance between performance requirements and packaging.
The chosen diameter for all the pipework is a mere 40mm for exactly the same reason. The smaller the pipe the faster the exhaust gas will flow and thereby transfer more energy onto the turbo's turbine and hopefully spinning it faster.
... and that's pretty much all there was to it, when it comes to turbo headers!
