You can see the injector lines are T'ed in the vid, but here's a pic.

Double stock pumps, no breakey drive shaft at high RPM, well not the pump drive one anyway.

you in theory have 2x fueling with 2 pumps, at the same RPMs, right?

wouldnt it be pretty important to have both pumps tuned IDENTICAL?!

Post by: rallydiesel on October 30, 2012, 12:40:58 pm: That's nuts. I've never seen anything like that with a VE pump. Anybody know where we could find more info on that one?

Post by: smutts on October 30, 2012, 03:00:47 pm: All that smoke shouts that it doesn't burn too well. Drilling and tapping an extra injector into each of those combustion chambers must have been bit of a chore. What is the horsepower limit of a single VE pump? 25kw per pot? x4 pots, x1.34102209 for horsepower, gives 134 horses. Okay I see why they might try this. Heath Robinson and Rube Goldberg would be proud. ;D

Post by: 745 turbogreasel on October 30, 2012, 03:04:10 pm: I don't think the timing really does have to be spot-on, plenty of OEMs use split shot injection.

There is no extra injector, just a T in the delivery pipe, and delivery valves keep anything from going the wrong way.
It also lets you get a ton of fuel without a big heavy plunger that doesn't like High RPM, and a nice gentle camplate that won't skip as easy.
Makes sense, but seems like a lot of work to get right.

Added bonus, limp home if a pump fails.

The VW one had two sets of injectors.
