Review: Owl Grenadier Steering Pump Upgrade

[ecohen2]

I don't actually mind the noise, I just wish I could reduce the amount of assist... It is way too light so you don't get a sense of what is going on...

was there any difference in tone? has this been put on a noisy pump? just curious if some of this noise is high frequency valve chatter.

Yes, the factory pump was much quieter after the boost kit was added.

What exactly is in their kit? they keep the stock pump and just change the valving and remap how it reacts to input based on speed?

and what is this pump cooler that you need to add?

Do you need to remove the pump to put the kit in?

I am interested in understanding how involved this job is as well. I watched the video for installing this in a jeep and all of the work is in removing the pump. Changing out the adjustable spring assembly to increase the psi is very easy if you can get access to it.

I did not remove the pump, it's straight forward if you're a mechanically competent person.
Tip: loosen the pump from its mount completely in place.
As Apex states, "DO NOT lose any parts"

I did not add a cooler... no issues in 25K plus miles.

The Apex kit?
* Spring
* Custom plug to replace the plug that holds the spring, allows for adjustment
* Manifold to TEE in the PSI gauge to set pressure

Ordered and look forward to installing once back in Cape Town

So strange how did you make the connection that this item would work with the Ineos ps pump?

45 years of experience doing stuff outside the lines and great connections.

Welp, unrelated to the new pump, but my steering shaft rubbed through a coolant line today. Has anyone seen this before?

Well, my issue has been, electric motors are very consistent when manufactured, you dont get 10% of motors coming off the line as being noisy. lots of NVH and heat tend to be your cues for impending doom, and yet we get mostly quiet units with some squealers as far as the pump assemblies go, and nothing is failing. so, I'm not sold on the actual motor being the assembly culprit just just yet, I'm still leaning towards it being the application, like a cheaply constructed or poorly designed impeller with bad bearings or out of balance, or a valve.

This is 100% electric motor.

Upping the pressure might help due to increased load on the motor maybe.
