1981 Suzuki Yanmar Clone Intercooled Turbo Diesel

[Dieselmonkey89]

Here are a few pics of my current diesel bike project. It started as a 1981 Suzuki GS750. I have installed a 10hp Yanmar clone with a rhb31 turbo charger and an intercooler from a Suzuki swift. I'm using a comet 40 series CVT and a final drive ratio of 3.5:1 If anyone has any specific question on parts of the build please feel free to ask.

There's been a lot of discussion about turbo-charging singles on here recently, so my question is - have you tested the manifold pressure, power output and exhaust gas temperature yet?

Not yet, but before I run the bike I am planning on installing a boost pressure, egt, and oil pressure guage. If everything works properly, I'm planning on regulating the boost pressure to around 6 or 7 psi to keep from getting the exhaust temperatures from getting too high. I have not reduced the stock naturally aspirated compression ratio so I'm hoping that 6 or 7 psi of boost will not damage the engine or affect its longevity.

Here is some fodder for you to review about turbo the single cylinder.
