Apologies if you've already seen this question
a number of times on other forums []
Has anyone used the Arnworx boost pressure tester?
I've borrowed one from Andrew Sweetenham at Promax
to see if I have any boost leaks anywhere. I don't think I have and I make
a full 18psi with no problems, but at the Weltmeister
Dyno Day the AFR graph showed me to be pretty rich, so I've
been checking things before going back on Saturday for
the 993 dyno day .
I have connected the Arnworx to the intercooler as
pictured and used a spare tyre, an air compressor and
a LARGE stirrup pump to pressurise the system. However
it doesn't seem to pressurise at all. I can even pull
the pipe off the banjo bolt while pumping and no air comes
out. What am I doing wrong?
I don't think I have a leak so the next thing is to
get some updated chips for 18psi and re-test on Saturday
Thanks
