The Quantum has 132 teeth on the flywheel. Turbo bearings don't require much pressure and the larger return helps to lower pressure in the turbo. If pressure were allowed to rise it would screw up the turbo.
Hi Mike,
132 teeth sounds reasonable at first; but where did I get my totally inaccurate figure from?
What I have done whilst checking pump setting was:
Set car to TDC on flywheel
Checked cam slot accurately aligned.
Inserted gauge which reads in 0.0005" per division.
Backed off (anticlockwise) until gauge stabilised. Reset to zero.
As soon as gauge started moving I moved crank 1 tooth at a time until the gauge peaked at 0.0865" This I deemed to be the peak of the cam plate for #1 cylinder. This corresponded to midway between 26/27 teeth on flywheel. A further 27 teeth on the camplate seemed to (symetrically) bottom out again. However from the previous peak to next rise is 40 teeth 40 + 26(7) is 67 times 4 is 264(6) AHHHHHH DUUHHHH! I've just realised crank turns twice speed of pump!!! so it is 132 on the flywheel thanks :roll:
I'll still post this, as I will add the list of readings in 'thou' that I took so, people can create the shape of the cam on the injection stroke and where the operating region is. Maybe I'll jpeg a diagram in the future. To convert to mm x by 0.0254
:idea: Interestingly my initial timing for TDC 0.0365 or 0.93mm is almost a flywheel tooth out :idea:
0, 0.25,1,3,6,10,14,
19,24.5,30.5,36.5,42,47.5,52,
57,61.5,66,70,73,76.5,78.5,
81,83,84.5,85.5,86 #86.5# 86
#mid tooth#
Maybe coupling these readings with piston movement around TDC would be interesting for future development work.
:?: Mike are you agreeing with my hint of a possible increased risk f frying/ life shortening with lower flow bearings?? :?:
