Former VWDieselParts.com Forum

Thank you for the assumption on my objective and for the explanation on the intricacies of IDI vs DI (TDI included) diesel engine design, but unfortunately I fail to see the relationship of your answer to my question.

My problem is that I want to build a bench tester for the pump and need to figure out which electric motor and pulley setup I will need.

Well, I did not know I this forum would also take gasoline engine questions, specially since it said it was more for pre-TDI cars. That is really nice to know!

However, I had a Bosch VE series pump in mind. If you run gasoline on it too, you sure are way braver than me!

When VW made the TDI head, did it move the location where the precombustion chamber exited the head to put the TDI injector? Ok, this may not make much sense, so let me rephrase it: if you have an IDI and a TDI head and flip them upside down, is the distance between the injector hole and the closest...

How much power is it required to turn a TDI fuel pump? I want to build a jig so I can play with the pump on a bench and need to figure out what kinda power I need to make it happy.

Odd question: how much power is it needed to turn the fuel pump?
