so i hear the new v6 has an electric power steering pump. wonder if its the same on the newer GT's too?

if so, i wonder what it would take to retrofit an electric power steering pump to our cars? i'd like to remote mount one so i could free up some space, my turbo comes fairly close to the PS pump as is.

notable things to mension is, yes i realize i'd need a new belt, and yes, the brakes are hydroboost. i wonder how the new 'stangs work this out? do they also use hydroboost?

137 views, guessing that means there's some interest?
anyways, from what i've found, i can delete the pump, and run an electric pump from an MR2. the only problem is that the amperage draw is pretty significant, i've heard anywhere from 30-50 amps, so a good alternator is in order.

and since i cant find jack for lines, i guess i could probably use double flared solid stainless steel brake line? thats what the stock lines seem to be made of anyways, that or aluminum. now the question is, what diameter is it and what threading do they use...

I cannot answer any of your questions except, as far as lines go, you can have hoses made at a hydraulic shop. Afaik Napa still does this, but there are shops out there that cater to heavy equipment technicians and the like, but usually they can make P/S hoses. Maybe look up your local Parker fluid power dealer and figure out what ittings you would need. Just my 2 cents.

yea, but what would that cost? i read steel brake lines can hold up in excess of 10,000 psi? the only limiting factor would be the connections and flares... the pump only makes like 2,000 psi tops (at load). the setup i saw it made a max of 1500.

Well, I cant really give you a cost estimate, maybe 50 bucks each tops? Thats a very wild guess though. With brake lines, i dunno if it would work. You have to consider fluid flow. Too small a line will increase pressure and heat and cause the pump to be less efficient and work too hard, causing pump failure. Besides, i think i would rather have a flexible line, be easier to deal with as far as routing and working around them later on. You have several options shen it comes to hoses too, single and double braid, synflex platic coated, or rubber, and different capacities etc.. and they make them right there for you while you wait in many cases. Then you dont have to mess around with flaring the lines and all that. They'll cut them to the length you want and crimp the fittings on and done.

I don't understand what advantage you are seeking?

It takes power to run a hydraulic pump and whether that power comes directly from the crankshaft, or indirectly from the crankshaft driven generator, makes so difference--other than that the direct mechanical drive will be inherently more efficient than using mechanical force to make electricity, to run an electric motor to convert back to to mechanical force, to run a mechanical pump.

The only advantage would be in a temporary burst situation where the battery's reserve could power the electric pump. This will be very short-lived however as a typical electric power steering pump draws 12A continuously and 40-50A in bursts when being asked to do some real work.

The OEM electric power steering units in most cars do not operate in the conventional manner. The electric pump is part of the steering gear and only runs on-demand when its assistance is needed--this is where the energy saving lies, not just because it is electrically powered.

Here's what the 2011 Mustang power steering rack looks like, perhaps it could be installed on our cars with relative minor modification--IF the computer control is separate from the PCM, IDK about that...
