Quite a lot of work has been carried out on the hanger since my last update. The initial design wasn't working out that well due to the top rose joint allowing the whole assembly to pivot upwards affecting the chain tension. The next few pictures will show the evolution of what I hope to be the final solution. The real test will be installing everything in the car but so far it's working out well. The original idea

No I am not going to be writing about the UK mobile phone operator! I am turning my attention to the R1 engine breathing requirements.
A number of BECs (Bike Engine Cars) use sausage filters, socks or unfiltered trumpets. Sticking with my theory that I probably can't design things better than Yamaha manged and the fact that the engine would of used an airbox whilst in the bike, I thought I would stick with the same idea and use an airbox. Using an airbox will have the added benefit of reducing the induction noise and it will allow me to direct cool air into the throttle bodies rather than picking up warm air from the engine bay. The question is what sort of airbox, what size and what size airduct ? Although I am still quite a way off from installing the engine in the car and subsequently plumbing in the cooling system, I have started to think about how I might approach it so that I do all the required fabrication before I paint the engine bay or powder coat the engine frame.
Managed to get some more done on the cradle on Sunday. I tackled the lower engine mount cross-member and mounts.
It was tricky to get all the angles accurate as whilst ensuring it lined up with the engine mount holes due to all the different angles at it each contact point. Chain clearance is good and bottom rad hose is clear. |
