lasstech,
Over 22% oxygen content in the air in a confined space is considered a dangerous & potentially explosive atmoshere in industrial confined space situations. Next time you get you oxy & acetelene tanks filled ask about oiling the threads on oxy regulator & see what the welding supply...
John,
Check this, Purolator # AS-802 or Porsche # 931-107-221-01. It is vented from the crankcase on a Porsche 924 turbo or 931, drains back to the crankcase, and pulls crankcase pressure to the lower pressure in the air breather housing. The connection on the air breather housing is upstream...
I don't know if engine size makes a whole lot of difference. In the 60s Chevys 6, SB8, & BB8 all used the same one. What would make a difference is amount of blowby & speeds engine is run.
I suspect that a industrial engine would run at a fairly constant & loaded speed. Instead of a...
I would experiment with something on the order of measuring capcitance between a plate located a small distance away from the roller and the roller. The Loctite might change the dielectric constant, therefore capasitanse.

I have seen a system that might work for you, depending on what substance you are regulating & pressure & volume involved. Some Porsche Turbos had what is called a frequency valve to limit the Fuel Injection frequency valve on the K Jetronic or CIS. A control unit changed the duty cycle of an...
Thanks for your answers.
I think I am going to use no pulse, just DC to .9 of my boost, then a pulse, ? freq?, with a 50% duty cycle to start cracking waste gate , then off at my boost setting.

Well I'm not really sure of what you are doing. In my head, I see a big cylinder with a piston in it. On one end of the cylinder is a spark plug & ports for getting fuel in & burned gas out. On the other end is ports from an oil resoirvoir & accumulator. As far as the spark firing the...
Looking at using a NO 3 way valve to shut off the boost signal to a waste gate. Porsche uses one on their 944 turbo to vary the boost as the EEM tells it. Do these valves operate off of straight 12VDC or a pulsed 12V & if so what frequency & duty cycle?

Primary length
P = ((850*ED)/rpm) - 3
rpm = speed tuned
ED 180 degrees + number of degrees exhaust opens before BDC
Primary Dia
ID = SQR(cc/((P=3)*25)) * 2.1
On a 90 degree motor firing such as V8, balance pipe Dia is 1.5 * P

There are some of those ign boves, MSD, Mallory, Crane, etc, that have adjustable timing modules or features. If it is just the ign timing you want to vary you could get one of these.
Something that I would look into is some of these single board micro controllers that program in Basic. They...
Electromotive used to have their manual for their programable ECU on their web site. It gives info on what sensors affect ignition timing & injector duty cycles.
