The pumps ??? 1.5L NA 1.6L NA 1.6L turbo --- 4 cylinder.
It took me a lot of time to get the spec.'s for internal pressure. If one o=
f you can verify that these are the numbers please let us know. At issue is=
the timing system. It takes a lot of force to overcome Torque and friction=
of roller assembly in housing. Besides the return-spring is one stiff cust=
omer. I shall test spring some other time. Piston is about 2 cm ( about 1 "=
) in diameter. Here are the figures : at 500 rpm 2.4 to 3 Bar =
at 750 rpm 3.5 to 4.1 Bar at 1000 rpm 4.6 to 5.2 Bar. S=
o now we can test those delightful little masterpieces of German engineerin=
g=2E.
I have a special test banjo and 1.5 inch gauge that I am willing to let o=
thers use according to some rules. The test-gauges do turbo boost and pump =
pressure while driving. Mounts just in front of windshield. In gap between =
hood and body. Can also tell you how to make the banjo. =

PS: I understand the rpm to be pump , remember 2 to 1 ratio..
