[@1jzfc999]

I see luke find just said on one of his videos this week that hes now going to run his elec hydro pump in the passenger foot well as a power steering specialist said having it in the back may have been contributing to his issues with them. Just a fyi

[@02honeydew]

Hopefully he sees this and some of the other posts about things that'll help.

[@mrguybrodude7373]

That was my first thought as well because that is way too far for that pump to be able to push that fluid for anything more than your drive to the grocery store.

[@dylanburch5379]

Yea these guys are on the money luke Fink has a good video on it pretty much explains how having it in the back drops pressure and adds alot more fluid which holds more temperature also you could try running a little trans cooler between then rack and line to save it turning back on its self.

[@Taylordrifts]

I just wonder if that would pass tech. Having hot PS fluid and pump inside the cabin.

[@1jzfc999]

@@Taylordrifts be worth asking. Could always build a box around of some sort and if the lines are AN hoses and fittings have a bulk head fitting. Similar to a fuel set up up at the back.

[@3694-k5s]

I would mount my pump as close as I could to the rack or box. Keep in mind that you're losing response time and line pressure as you increase the pressure line length.

[@nickquatrini]

Has anybody tested this to confirm? I'm doing the install soon and I'm not sure where to mount the pump. But I would think in a hydraulic system the length of the line shouldn't matter because fluid doesn't compress. Therefore once the pump generates pressure that pressure would appear on the other end of the line almost instantly since the fluid doesn't have to flow to build pressure. I would think the flow rate of the line would be more vital than the length of it. Thus, if he is having issues with response he should opt for a thicker feed line, not a shorter one. Its the opposite of intercooler piping because air compresses, fluid does not. But if you have real world experience with this, I would be curious to hear what you have to say.

[@3694-k5s]

@@nickquatrini I wasn't saying that the fluid would compress. The pump still has to move the fluid and that has weight and resistance. The longer the hose the greater the resistance...the slower the response time. The wall thickness and material does expand and contract and will have an effect as well. I would want the lightest system with the least resistance and deflection. A heavy or thick hose adds weight to the vehicle...not what I'd want.

[@Blakelikesfood]

My receipe: 1)Saxo/Clio pump (Europe EBay)2)100A relay to run it 3)1-100Sec time delay relay, wired to 100A relay so pump comes ~5seconds after car starts so doesn't fight starter/ hord all volts.

[@KARR]

Hey dude Check out kmiata they have a really cool electric steering setup. Its mounts on the column like chevy and has a pwm. I was gonna get it but never did.

[@joshuagamilla643]

I think there’s a possibility your first pump went bad from when you welded the mounting brackets with the pump still attached. I’ve had electrical components such as o2 sensors go bad from welding an exhaust. But it’s also highly possible they gave you a bad pump.

[@thecannabiskidfortier6219]

I think the reason why the steering is stiffer, it's the length of the hose for the power steering

[@SirVic42]

The length of the hose and then that 180 just before the fitting to the rack may be crimping the flow.

[@chasemeyer6688]

TheCannabisKid fortier or the electric one doesn’t output the same amount of pressure as a manual one

[@BOOT]

Electric any pump puts out a constant psi, usually more than idle and about 3000-4000 rpm-ish. Since Taylor is use to high rpm manual pump psi it's gonna feel harder and of course the long lines n fittings will drop it some.

[@max_coast]

It's years after the fact, but that Volvo unit puts out about 600psi and the Miata rack in an NA needs about 1100 or 1500 in an NB. A Holden Astra unit is popular and outputs 1500psi. Some people use MR2 units, but they're worse for this application at about 300psi.

[@SwaggyT91]

PUMP IS IN LIMP MODE Somebody still has not cracked the CAN signal, i have the same pump and its stuck in the middle, when it does not have a CAN sig its not strong enough for parking and a little light at speed.

[@CoreyStatler]

Yep, used this same Ford/Volvo pump on my 07 Focus and had issues when at auto-x, kept hiccuping which led to cones being hit. It is now gone. It was fine for daily use but anything fast it wasnt having it.

[@eddiereichel9354]

Im pretty sure its not CAN but PWM. Can is a communication protocol.

[@CoreyStatler]

It might be PWM controlled internally but the signal comes from the CAN interface of the vehicle to talk to the pump. I think the default is to run at 70% but that is not enough when tasking it with a load in drifting or racing.

[@Taylordrifts]

@@eddiereichel9354 From the diagrams I looked it it was can H can L so i think it's CAN operated.

[@eddiereichel9354]

@@Taylordrifts that may be I guess I just assumed PWM. I mean unless you can find a stand alone controller the only option for this pump to develop the pressure is going to be pair it with a lower pressure rack that or design a controller to go behind the canbus. Can is just a communication protocol. There has to be a workaround because the pump "receives" the signal over can and the controller just turns something on or off.

[@Watchmedome3017]

Luke fink did some research and a power steering expert told him the biggest mistake people do is mount the pump very far away from the rack. It’s better to mount it as close as possible to the rack it’s self.

A lot of good brainstorming in the comments. One comment about the voltage dropping on the skidpad runs, looking back at the video it looks like there is even a yellow light flickering every now and then(warning light?) and it looks like a low to no charge situation. Also a comment about the long runs of the fluid lines. Possibly replace with a hard line and possibly larger diameter for more volume, especially on the return. Another point about the pump possibly needing another input for full pressure output, but I assume that this pump shouldn't need that if it's been spec'd for universall use.

That Volvo P1 pump needs CAN bus communication to run at 100% power. If you just wire it up and turn it on it'll run at 70% all the time. MaxxECU can control that pump so that you get all the power.

[@timsminigarage]

You could see the voltage dropping to 10-11V when lapping on the oval - mostly at full lock. That could cause both the power steering to be weak and a misfire?

[@blingdesigns]

That’s a diesel pump which is ecu driven. Need a twr ts astra pump and also putting it in the boot will cause pressure drops and delay In the steering when you first pull the wheel on initiation. Also the belt set up is not ideal. Routing it with the smaller belt means you have lost 2/3 of the belt wrap on the Front pulley. Best way is buy a pulley for a vf commodore from Australia. They have a pulley and bracket that bolts straight onto the bolts where the alternator was and it’s about $50. Then you can still have full wrap around the bottom and will have less chance of belt slip under revs. I have all the gm part numbers for the pulley and bracket if u need them.

[@aflea8272]

2 pins need the stock ecm to tell it what voltage. if you want that alt will work just needs a new voltage regulator with a 4pin. its more or less a 20$ part and 30 min or work.

To be accurate, this is an electric-powered hydraulic pump, replacing the mechanically powered hydraulic pump fitted as standard on the LS engine. Electric power steering is something different, where there is no hydraulic system, and is used on many cars.

You’ll be on the net looking for the parts the instant you see them jack up the car. Not exactly an electric power steering system. It’s an electrically driven hydraulic power steering system. A true electric system doesn’t use hydraulics it uses a manual rack and a motor on the steering shaft.

[@rallias1]

You mentioned the power steering pump can pull up to 80A. Are you providing the power directly from the PMU? According to the ECU Masters PMU documentation, you're getting the following amperage available. 10 x 25A(cont.), 6 x 15A(cont.) with overcurrent and overheating protection. Outputs may be paired to increase continuous current capability. Current and voltage is measured for each output Are you giving it enough whatyamacallit's to supply 80A of current?

[@gordowg1wg145]

I was thinking just fit a smaller auxiliary drive pulley on the crank, but I see why you didn't go that route. The 'binding up' is usually because the pump cannot keep up with the flow required to match the rack movement and, in extreme cases, there may be problems with the fluid overheating and boiling - that may be part of the issue with your installation - have you upgraded the cooling for it's fluid* as the OEM cooler is often just a run of plain pipe in front of the radiator and it will certainly not be up to 'spirited' driving. Some of these electric pumps can draw a LOT of current, so that may need to be taken into account. Some are also controlled by either voltage or PWM, and can be modified for manually selecting the amount of assistance - you may also be able to have it driven by the ECU, if it supports it and, if you're fortunate, possible by the gear. Provided you use a reasonable size for the fittings and hoses, a rear installation shouldn't cause too much of a problem - I might suggest an accumulator (mounted to the front?), to help maintain a consisent pressure to the rack under extreme direction changes. *A small oil cooler on the return line should make a significant difference.

[@Taylordrifts]

My thoughts are still on bad pump because even just sitting it was stiff. But if a new thoroughly tested pump doesn’t solve the issue then it’ll be time to change and do electric column or work on solutions. I didn’t route it though my cooler because from what I’ve seen it doesn’t overheat like a normal pump would.

Another thought is just like electric...

[@mrguybrodude7373]

Taylor, I hope you see this and other's comments man. Your pump lines are too long. I understand the pump setup wanting it to be in the rear but it just isn't going to be at its full potential like you want. You will either need to put it in the cabin somewhere, maybe there is room left under the dash because otherwise the passenger floorboard is the only place unless you can magically make space in the engine bay for it. Also, that tight bend and the hose wrapping around is being way too restrictive. (Source, I have seen many try to make it work in the trunk and I have as well on small and big cars and moving it forward to shorten the lines by half of what you have or more will make a world of difference.)

so something you need to look into and I just thought of the terminology is it but it's called pressure over length of run that use it in plumbing of houses and basically you have to know the pressure coming from the main or from the city whatever your supply isand then the length of pipe to know the pressure drop but it also will change by the diameter of the piping and you can achieve different things if you need more pressure or if you need more volume
