The New Engine

 

After a couple of weeks scanning the various websites, I saw a chap on the YAHOO BEC bulletin board mention that he had just purchased a brand new Yamaha R1 engine for a company called PDM RACING. So a couple of telephone calls later and I had secured a brand new engine, complete with all ancillaries/looms. 2 Days later and a courier arrived to deliver it.

 

I have taken the throttle bodies off, hence the big inlet holes. I am keen to put them somewhere safe for a while and block the holes to stop unwanted bits getting into the engine. I have also taken off the thermostat housing from the top of the engine that would have connected to the brass pipes sticking out the top. This will need to be relocated once the engine is installed.

The above picture shows the exhaust outlet. Again, I am stunned by the technology here. The circular alloy unit at the bottom of the engine is an oil cooler! That's a water to oil cooler as part of the standard install. Apart from the oil filter (in black) the other parts of note are the emission control unit that has a pipe going to each exhaust port to ensure any unburned fuel is burned in the exhaust by adding air to the hot gas, before it reaches the catalyst.

The side profile of the engine is really small, I guess due to it being 1000cc, so it's only 250cc per cylinder. The complete engine/gearbox is about 65kg complete and I can carry it around the garage, although it is a bit awkward.

The throttle bodies below are a work of art, so small and neat.

In this picture are 4 throttle bodies, the fuel rail and pressure regulator, 2 sensors, 4 injectors, the loom, a throttle cable setup and all of the pipes. It even includes some other air control looking thing that I haven't quite identified yet. I just can't get over how small, light and impressive the parts of a bike engine are.

The picture below shows the output shaft, which will have the prop shaft connected to it. My first impression is that the position couldn't be better. It sits about 4" above the sump and looks like I should get a really good and straight prop run to the diff.

 

Just to put the size of this engine in perspective, from the bottom of the sump to the highest point of the engine is 19". I have taken a picture with my brother, James, next to the engine. Both so small yet so powerful!

So, the next step is to look at baffling the sump, and have placed an order with a company called ALLBIKES for one of their DIY baffled sumps. This will involve taking the sump off and drilling/tapping a couple of holes in the engine crank case to keep it in place!! These sumps have been used by the bike engined sidecar boys for some time and have now been used successfully in several R1 powered BEC's. This will be enough to avoid oil surge when driving even on track days. I must say, I am not looking forward to drilling holes in the crankcase.

I have attached an image of the sump baffle below but I think I will wait until I have started the build before attempting the fitting - I'll wait until i'm a bit more familiar with drilling and working metal. I think this may be a very bad first job of the build!!!
