Hi chaps, Finally might have the funds to pursue this, ie. Remove power steering pump from factory location to free up the inlet to the turbo to add things instead like move the AFM, a large bell mouth and compressed air jets, gas feed, heater/feed for vapourising alternate fuels etc Other than an electric power steering pump with the appropriate load torque sensor to spool it up etc I have obtained an alternator from a ford transit diesel which has an air pump on the back. Have taken the air pump off and it reveals a shaft with nice splines and a couple of fitment points, all I need to do is get a pump, machine it to put matching boss for the splines and plumb it in place. It is a little tight behind the alternator but think I can live with that. The pulley size will mean the ps pump might run a bit faster, so I was thinking of running a smaller pulley but add an external voltage regulator to get more charge from the alternator as it would be turning at lower revs during that time at idle etc... ie By feeding more current to its field coil, Anyone done anything like this yet ? btw:I might have posted similar request some 3 years back or maybe on aus.cars but my memory is leaking, <sigh> cheers

has p/s technology progressed since 1986? are there smaller p/s pumps from say, newer cars that you could use??

In any case if I do go for a smaller pump I wouldnt really care if the effort to steer went up a bit as a consequence, would mean I prob wouldnt need to get my upper body work as much at the gym, its just bad having to go through doors sideways Some original photos have not been recovered yet.

i think itd be a lot easier to get a top mount manifold and to relocate the turbo rather then the power steearing pump... you can pick a fairly decent one up for real cheap... been hearing decent things about the cheap ass manifolds.... just dont buy there turbos ahahha...

I'm being stingy as I already have the alternator and its also a 100Amp unit ! Besides the number of times I get stopped, the first things the cops check is my turbo and I'm guessing I'd need a permit for a high mount, then I'd need a insulator so I dont flake the paint off above it in one spot and all the turbo messing around etc, New dump etc .... Putting the PS at back of alternator seems the lowest cost combination and wont attract the plods attention and get to try something different,

Do whatever u want and goodluck to you..... Personally i would just go topmount. How much is there really to gain performance wise for the cost and hassle What kinda turbo you got?

T3 high flowed and added a turbine speed sensor to the inlet, one of those high speed types with 5 nanoSec response. This allows me to check not just speed of the turbine but the rate it spools up, ie Acceleration since I get a pulse for each blade, working out how to make a dash display is another issue I'm expecting to see more rapid spool as there will hopefully be less vortex type turbulence at the comp blades, ie Starts out more laminar. Going top mount will cost me more and mean greater things to mod, as well as attracting more attention from my many inspections, putting the ps pump on shaft on back of larger alternator I already have seems to be fairly easy in short term - dont know re long term reliability of the extra straing on the pulley bearing or belt, but hey its worth doing something different, Some original photos have not been recovered yet.

good on you for thinking outside the box! Results will be interesting.

Yes, keep us updated. Some original photos have not been recovered yet.

FYI power steering pump on the VN-VR is the same as the later VL's, with a different pulley. Looking at some modern small cars I've noticed that pumps are smaller these days so it might be worth looking into that.

Yeah I dont mind a bit more force on the steering now and then provided it wont suddenly seize up due to not enough flow, will take a look around the local wreckers then get specs from the dealers.Vane pumps are pretty simple devices, and they may well now have smaller hubs and still flow as much as the older ones, thanks
