does anyone else have power steering off?

[kenith15]

Whilst tracking a 182, what does everyone else do about power steering, removed or not?

 

[Tomotek]

We have our power steering removed in our race car.. bit of a handful in the paddock, but once about 5mph it’s absolutely fine.. we really like the direct feedback you get

I tried my epas turned right down at Croft and it was like driving a GoKart. You've always got pressure against your forearms and your grip starts to ache after 15/20 minutes. I have mine set some where between 1/4 and 1/3 assistance.
I watched your latest race video in the wet and your steering wheel had some right kick back (when it was attached) looked a handful

Anyone have any experience or know of after market pas pumps? Something electric driven as my steering is a lot heavier than I remembered when I last drove, Im running 4.6 castor but the stability is too good to give up with it set to that.

I've got no PAS, you get quite a bit of arm pump and wrist ache after about 10 laps. Definitely worth it because the car feels direct and above 10mph the steering is pretty much assisted by sheer speed anyway

Some people have used the Citroen Saxo pump if you want to keep the hydraulics.

Ah yes I have seen a couple posts before on the saxo one. My only thought is that the actual steering resistance would be the same or even less.

mines stayed in, but remove some of the fluid b4 the track or it pisses out everywhere as I found at Donnington couple years back

Just change to epas its so much easier.
Clears loads of shite out if the engine bay and you dont have to worry about oil pissing everywhere potentially setting on fire if it gets as far as the exhaust or your pump seizing up with the lack of oil in it which in turn throws your alternator belt off potentially damaging your cam belt which could ruin the engine.
Worst case scenario, just saying lol

Had the same issue at Snetterton.

Just in case anyone is interested, I fit a Mishimoto Cooler into the return feed before the Power Steering fluid bottle, fixed it infront of the radiator and it works a treat. Never had an issue since!

Very interested to know what you have done, ie have you retained the original rack, blanked it off and removed the pump, or is there more to it.
Also might sound a daft question, but what diameter steering wheel do you have fitted?

Reason for asking is my PAS effectively deleted itself today, middle of a wet race at Lydden Hill.
Very weird experience with on-off assistance, while the pump expired and the fluid disappeared.

For the second race we decided to disconnect the pipework and drain out any fluid that we could, but of course we had to keep the dead pump connected to keep the alternator running, being wet had all lights, blower etc running.

Although I'm a bit of a wimp, and Lydden is all corners, and I have a silly little 300mm diameter steering wheel, and I had s**t AD08 tyres understeering all the way, I still reckon I'd need arms like Arnie to comfortably get the thing turned in and held while still concentrating on the apex and getting the power down.
And that's all my excuses done for a fairly crap performance! Oh, not quite, the dead pump seized up, of course it would with no fluid, put massive resistance on the belt and then I was 2 seconds a lap slower than before! When I came in the pump had pretty much melted, engine bay full of smoke! At least I tried, and it was the last race of the season.

I would be keen to just delete the PAS and put a sensible sized wheel back on, but should I also be looking for a different rack?

Many thanks, Andy

@banhama I think the hydraulic rack has more resistance if you disconnect it and dont replace it with grease and bung the holes up, I remember reading

That makes me feel a bit better Zach, i'll hold off on that gym membership until I know for sure if i need bigger biceps.

 

[robzracing]

Not grease. You need to fill the rack with power steering fluid and then loop it with with the proline kit or PMS kit. Or make your own.
If you use a 330 or 350mm wheel you’ll find it easier of course.

Hi Andy.. we use the std PAS rack that’s just blanked off and either side the piston looped.. I can check the size of the wheel but think it’s a 350mm.. check out our build thread

Many thanks for the replies, I think I will be getting the PMS delete and blank/loop kit, and a 350mm wheel and see how that goes. Definitely the cheapest option to start with, then if I still find I'm too puny I'll have to think about electric assistance.

Oddly enough the weight loss will probably mean i'll have to start adding ballast! As I'm in production class min weight is 1075kg with driver, we weighed in at 1078 so getting near the mark. Or maybe I'll just go fully skimmed next season, dump the glass windows, electric winders, OEM door cards etc, and move up a class.

Thread dig to save a new post.

@Tomotek and others that have removed PAS totally on their track cars, how much heavier is it?
Wish you had PAS or EPAS?

My car will have a gripper, 4.5 deg caster, 3.5 neg camber and use full slicks or high grip R spec (Yokohama AO50).
Keen to ditch it (weight and less to break) but also want to do more then 5 laps before arms die

I’ve ditched mine and it’s fine once you’re moving. It’s quite heavy when trying to park or moving at very low speed but once above 5-10mph it’s fine. The feedback through the wheel is amazing without it.
