Default Place to do injector test at 100bar

Does somebody know a place where they can test fsi injectors at operational pressure of 100bar?

Yeah in the Netherlands. Would have to post them anyways, we haven't got that here.

Most of them say they can do direct injection injectors but it's only at the pressures of normal ones.
You sure they can do it at 100bar?

It is important because people found out that if they leak this usually occurs at around 30bar upwards. Won't see that at 8bar tops.

Diesel testers surely should have the kit that can do hundreds and thousands of PSI, so it's just a case of getting adapter to connect and putting different fuel in the system.

If everything else fails, there is a gap in market which could be filled with some DIY getting FSI fuel pump and driving it from electric motor to generate pressure.

I haven't found information on diesel testers.
About the ASNU fsi/gdi box (gdi meaning gasoline direct injection nothing Diesel) I also found this technical info:
http://www.asnu.com/downloads/low-pressure-gdi.pdf

All great and well and indeed testing abilities at low pressure are also important, but besides that it is a big bunch of BS, fellow audi enthusiasts on an American forum have found that leaking FSI injectors from our S6 and S8s will only start to lose fuel above 30 bar system pressure.

I've got some hydraulic equipment that can easily be reduced to produce 100 bar and filled with another liquid. I'm slowly leaning over to getting 10 adapter bungs machined and buying 10 borosilicate lab flasks and a pwm driver board.

I just wish I could outsource the testing
