While I took some time away, it was obvious a lot of work was still going on elsewhere and, case in point, is our friend, Russell Sutton. His 14 cylinder Yamaha XV radial engine project is moving right along due to his dogged persistence and commitment to making it happen.
When you look at the engine, you'll see he's managed to fit exhaust manifolds from each of the 14 cylinders which join the ring pipe in the rear while still providing clearance to neighboring cylinders and parts. The coils are LS1 units and there's a turbo which compounds the difficulty of running the exhaust.
Next up is finishing the oil pump manifold and then fitting the injectors into the intake manifolds which he says he hasn't quite figured out how he's going to do yet, but judging from the progress to this point it's a pretty sure bet he'll have it handled soon.
I still haven't quite got my head around designing and building a 14 cylinder twin row radial engine using cylinders from a motorcycle, but the simple fact that there are builders out there who can come up with an idea like this and then do it, makes the world a better place. I'm really looking forward to seeing this beauty spinning up.
