In a DC power system on a car, the negative(usually) terminal uses a "chassis ground" for power "return".This is your "power ground". It can have a voltage drop of up to .1 volt across it for accessory and charging loads, and up to one volt for starter loads. For signal circuits, such as sensors, sometimes the .1 volt drop across the frame ground could cause calibration errors, so a "signal ground" is provided. Sometimes the signal can even "float" above chassis ground, as through a protection diode with a, say, .6 volt forward voltage drop. Can't use chassis ground return for such a signal.

The port in the regulator used is not big enough, plus it needs time to react. Who is Walbro, where are they.?? Basically, I am looking for sources for good quality, large volume, but really don't have to be high pressure, submersible fuel pumps. Controlled voltage to a pump is still more elegant than staging, since varying voltage to a DC motor varies its speed (and therefore the volume output) infinitely. Hence the desire for variable speed pump drive. Tom is RIGHT! Running a big pump at lower voltage/speed most of the time will do the job, and increase pump life IMPRESSIVELY! If one wants to get seriously complicated, it is very feasible to vary the speed of one pump, and then stage in a second, constant speed pump for big loads. (The first, variable speed, pump slows back down when the second pump first comes on, then speeds back up as load increases further.) hits the FP regulator . It is way easier (and much more efficient and accurate) to regulate pressure precisely if flow through the pressure regulator is fairly constant. > I only wish to own/operate such a thirsty beast in my lifetime. 8~) The output would certainly be nice, but maybe with about 10% less thirst would be even nicer!! :-) Regards, Greg > Mike V ------------------------------ From: bearbvd@xxx.net (Greg Hermann) Date: Sat, 2 Jan 1999 11:59:16 -0700 Subject: Re: conversion.... >anyone know how to convert inches(mg?) manifold pressure (aviation) to >psi? >thanks, >rog 29.92 inches of mercury = 14.69 psia=1 atmosphere.

For a shunt would DC motor, Voltage relates to speed, Current to torque. Field current and voltage want to be pretty constant for correct excitation. Too high a current (cooks the insulation with heat) or a voltage high enough to break down the insulation are the two failure modes for motor windings (this applies to all types of motors.) For series wound DC motors, more complex, but voltage control of speed still works, and without hurting durability, as long as you do not stall one (with an overload) with too high a current going through it. You just cannot expect to get full rated torque at lower applied voltages, cuz you will not have enough excitation. Even so, with a liquid cooled motor, like most fuel pumps are, it is pretty hard to cook one this way. What you need to watch with a PWM scheme for lowering the voltage to a DC motor is to have good filtering/smoothing on the output to the motor--the high frequencies from the PWM switching can be quite hard on the windings from a mechanical standpoint.

The memory of the computer is stored in RAM that is fed by the car battery (thru the appropriate regulators etc). Due to the low current drain of the RAM, you'll need to disconnect one battery terminal (not both) and probably leave them off for 5 minutes for all capacitors in the ECM to fully discharge.

If you are running headers with a low restriction exhaust system a properly placed air inlet tube in the vicinity of the collectors will draw in fresh air or could be connected to a compressed air tank. Drag racers have been using this method for years to evacuate the oil pan ( neg. pressure) to help seal the rings. A few year ago Car Craft ran an article on a 455 Pontiac race motor and getting it to pass the '92 standards IM240 emission test. They used this method to introduce 02 upstream of the cat's. You need an low differential pressure anti-reversion valve typically used in late '70 early '80's AIR systems. Sure wish that my wife didn't through out that edition. The article ran Aug. '95 or Aug. '96. - ---------- From: Greg Hermann[SMTP:bearbvd@xxx.net] Sent: January 1, 1999 9:49 PM To: diy_efi@xxx.edu Subject: Re: oops...

Mebbe a mottled pattern high intensity light, filtered to match a plate color and aimed at the plate would work better (and cheaper) than an LED screen. (Plus it would, technically, not be "obscuring" the plate.) Make it a thirty second delay, and add a light for the rear plate just to be sure! Nest question--what do we use to trigger (turn on) the same lights in the presence of one of the roadside smog sniffers (which I think are infra-red based.)

There are often "group purchases" going on on the Buick and Syclone/Typhoon lists to buy there products.. The pump I was referring to is an in-tank unit that produces 255 litres per hour at 38 psi..
