OK, so after a bit of a clean, although not a full clean, it was time to start thinking about putting the engine back in. However, before I could put the engine back in, and the reason it is still out of the chassis, I needed to modify the fuel pump arrangement for the new system. As I now have two independent fuel tank, I am using two lift pumps to pump fuel from the separate tanks into a, not yet finished, fuel collector. Then the pressure pump takes its feed from here to the fuel rail, and the fuel rail returns to the collector. This however means a bit of a reshuffle of the pumps etc.

Fuel Tank Pannelling
Sunday, April 18th, 2010With, literally, a few minutes between customer jobs, I thought I should try to get something done on mine. The next job on the list was to panel in the second fuel tank. So it was back to the paper templates…
Fuel Tank Foam
Sunday, April 18th, 2010In order to try to stop fuel surge, I managed to get my hands on some tank stuffing. I had to feed it in through the filler necks in tubes. I haven’t had any surge yet, but while I am working on the fuel system I thought I may aswell.
I have a small amount of foam left to stuff the fuel swirl pot, (when I get it drawn up…)
Refuelling System
Thursday, April 8th, 2010There has been much debate regarding refuelling for SPEED. I have however checked and had the OK to use the ATL dry break system, rather than other systems on offer. This is a ‘proper’ dry break system and as such I am happy to use it. I know that a different system has had the OK, but I am not happy to use it, as there is nothing to ensure no fuel spillage!
Anyway, below you can see the female part that goes on the car. I forgot to take a pic of the dump churns, but all of the CTR cars use these which means we dont have to buy different churns for the cars, hence saving a load of cost. That said the Juno is different but they came with the car!
Generator
Thursday, April 8th, 2010Now, I know I have put up a picture of the old generator before, but I thought I would show the comparison of new and old. You can see the damaged windings in the old, but the whole thing looks a little discoloured. This may just be a different potting compound but some areas are darker than others. I cant see any physical damage to the rotor, so I can only assume that when the original reg/rec went wrong it may have either been caused by this, or perhaps have actually caused it. But I am not too sure.
