I've rebuilt and tuned many bosch VE pumps now, I can build a pump fast enough for most people, but if I ever built a big badass motor again, I'd likely be sending my pump to giles. His stuff is great and you can't beat the prices for what you are getting.
Where's the one that shows the untethered 14cm bounce?

That would be the FF horseback riding
:shock: :lol:
don't suppose anyone knows of a 'iles'in the uk? I'm too cheap to ship across the Atlantic... :roll:

Or at least part of the answer. Saurkraut pointed out that the videos I've just posted are a good answer to the question this thread was initiated for. There will definitely be more info to follow, but if you're still curious about what we're doing here that you (or even we) generally couldn't do at home, have a look at
this thread.
In the the boost fuel video I noticed the graduated measuring dealies weren't exactly level. Is that a difference in fueling from the pump, or just the way they're set up? Oh, and now I wanna make my own test bench too. Thanks a lot man, all I need is some other unpossible project. :x
Anyway, how does the machine record timing events, piezos in the injector dealies? Looks awesome man.
The slight disparity in fuel levels within the graduated cylinders in the full-boost fuel video was because we did this video unscripted - you were looking at a preliminary test before Giles had even finished calibrating the pump, so the levels were not yet perfectly even. It was a matter of fuel delivery from the pump; The disparity is well within manufacturer specifications, but ideally (especially in a performance pump) when we're finished, everything is perfectly even.
As far as the timing measurement, that was on the other side of the pump, which we just didn't move to show in the video. It is a mechanical, piston-type timing gauge measured in millimetres to show internal pump movement within the housing.
Glad you like it.
