I am interested in your work on tuned pipes, I don't know much about the boats you run. Will the boat accelerate and come onto the pipe without any any outside assistance?I run tethered cars but we have a guy in the centre who will horse them up to a speed were the pipe will start to work and the car then accelerate away that speed is around 100mph.
James, I'd like to switch gears for a minute and ask about the billet block construction of these engines. Did you possibly use a broach to cut the crankcase transfers in these? Are you willing to share photos of the transfers and or the process to cut them? Beautiful work BTW.
