darrenjlobb's Project M-TDI Twin Turbo Supercharged Derv Bus

[darrenjlobb]

Despite the current restriction of air / boost, as the car stood, with everything maxed out, the injectors could only really move enough fuel for 140-150hp at most, which although was all very well and good to run it in, was really starting to get rather boring by this point, so it was time to start playing...

I have already built a VE pump capable of moving some fairly serious ammounts of fuel, which on an IDI would be all I needed due to the nozzles being so free flowing as stock...but with DI, its a very different kettle of fish, which nozzles in the injectors always being the next big fueling restriction, so I needed to find / modify some to fit!

A few emails / phone calls later, and a 3 weeks wait all the way from Texas USA, these turned up at my door:




So after some brief prayers for the poor DW10, it was time to make them fit...as with everything in this build, its not just a case of bolting them in, despite being fairly custom made anyway, they simply dont fit my current nozzle holders without "modifications", so, out with the grinder on one of the most precision parts of the entire injection system....






Then was time to test them / shim up the springs to get them popping off at the correct pressure, notice the rather chronic amount of fuel exiting the nozzle!!!



So for all the people wondering, that's what the delivery from the states was all about!

Now we need more air, badly!!
