TeoAlfa,
A standard gear pump? I believe that if the pump is putting out 7-8 BAR and the pickup is in oil, that the orientation of the galley (vertical, horizontal) and amount of g-force (0-2g) will have little effect on the pressure.

koldone2,
I suggest that you contact Schenck and ask them what options they can supply or get details about the feedback instrument they use. This would allow an instrumentation or electrical engineer to develop a solution for you, if not available from Schenck.

Thanks for all the comments.
I spoke to an NGK technical representative about 10mm surface discharge and fine wire plugs. It turn out there are a couple of problems that will prevent me from using these type of plugs. The most difficult one is the heat range available. NGK claims about...

Did your test conditions approximate higher compression ratios? And, tip proximity close to pistons? If not, any ideas about this?
patprimmer,
Yes, I'm aware of the Side or Wire electrodes. In fact some are shown on the NGK page that I referenced. Not as many heat-range choices...
I’m building a 4-cylinder, air-cooled, twin-plug, ~1.9 liter autocross engine. The cylinders are
Nikasill with JE Pistons. The pistons will be TB coated on the top and have anti-friction coatings on the
lands and skirts. The combustion chambers have been reworked to unshroud the valves
and...
I'm looking for a table or calculation that will allow me to determine the volume flow rate of an automotive gear-type oil pump. I'm guessing that I need gear pitch. diameter, length and pump RPM. Anything else?
Thanks,

Typing "water copper contact angle" into Google yielded 1,800,00 hits. You might try that with some additional terms or exclude nonsensel terms.
Good luck,

IRstuff,
I'm not sure how additional info will help... but-
We are studying phase changes in Liquid Crystals. The setup involves viewing LCs with a simple microscope through crossed polarizers. The LC sample is heated (working range 30-60*C) using Thermo-electric coolers... (reversed). A...
Hi,
I'm looking for a source of 25 x 75 mm microscope slides with almost any thickness from 0.1 to 3mm. The material needs to be relatively tranparent and have high thermal conductivity. I would appreciate finding the manufacturer, vendor and part number, if possible.
Thanks,
Rink
Hi all,
I like the way this discussion is going. I just used Google Scholar and, using the search term "cryogenic treatment of crankshaft," got 96 hits. Some of those are books, some papers and some are patents.
Using other search terms, I see a lot of references to Cryogenic treatment of...
Okay, thanks for input.
I have revised the order in which the processes should be done:
1. Crank magneflux & inspect
2. Cryo treat
3. Grind (if necessary)
4. Remove/clean/replace passageway plugs
5. Balance
1. Rod inspect/straighten
2. Cryo treat
2. Rebush small end, 'trim'/hone big end
4...
Hi all,
Engine- Flat four, air cooled, was 1588cc - soon to be 1883cc, head/valve work, twin plug ignition, split-lobe cam, etc.
Service- Dedicated, lightweight autocross car.
Hoping to achieve 35-40% power increase but mostly a higher and wider torque band. I have been advised to cryo...
Hi all,
Looking for a very small quantity (a gram or less?) of a material that is non-spherical, with a diameter in the range of 1-15um. We're looking at defects in a thin film of Liquid Crystal and would like something besides round latex beads. A rod-shape (d~1-2um, l~5-10um) would be...
This thread is related to a recent one here in this forum, posted in mid January 07-
"Flywheel/clutch weight issues"
Based on the feedback from that discussion I am planning to go ahead with a lightweight flywheel/clutch.
How effective will an electronic rev limiter be in this...
