How much bhp is needed to run the power steering?

[MarkCup]

What do we reckon?

I've heard 2-3 bhp, and also someone claiming 8-10 bhp.

I'm going to get my car on the rollers soon to see for sure...any predicitons?

 

[Marky_]

Have you done away with the power steering??

 

[ben_p]

1-2

 

[Mark One]

Have you ditched it then mark? mkII ran without PAS for a while and thought he could feel the car pick up a little better (1.2 8v)

 

[MarkCup]

Have you done away with the power steering??

Yep, mine's now gone.

Picking it up tomorrow once everything's been realigned again.

1-2 bhp will be disappointing!

 

[Marky_]

Legend.

I'd be hugely surprised if it were as high as 8-10.

 

[mini-valver]

Get a saxo pump if you want to keep PAS but not on engine power....

 

[fuel_slut]

Maybe 1-3 bhp, but dont forget the pump, pipes and fluid must weigh abit! So that might be worth 1 bhp alone.

 

[MrMark]

i thought the power steering was electric and didnt use pumps

certinally isnt on clios. Even if twas electric, it still has to get the energy from somewhere. Doesent matter if the altenator takes the power or the PAS pump does

 

[MarkCup]

It's hydraulic on the Renault Sport Clios, electric on everything else.

The whole rack, hydraulic fluid resevoir, pump, and associated pipes/tubes etc. all weighed approx. 20-25kgs.

Manual one? Maybe 10-15 kgs?

So a 10 kgs gain in therory - would up my power to weight to 192/ton...add another 2 bhp as well, and I'm at 194/ton.

So if that's the case, I just need to change the passnger seat and take their airbag out and I'm at 200.

 

[Michael172]

dude, you may as well shave the plastic off your wing mirror.....

 

[172blue]

Be interested to hear the answer to this Mark, after all my Elise has no PAS either....

So here's a question, does power steering increase your emissions?

No because the engine is exactly the same.

Although in theory it affects your MPG as it weighs more and saps a bit of power.

So removing it does reduce your carbon foot print, in theory of course.

taking stripping seriously.

 

[Iridium]

Surely, none on the rollers, because whilst the wheel isn't been turned the pumps aren't running?

[MarkCup]

The pump still needs turning so it will drain some...just not as much as when it's under full load.

 

[Jaff]

put some expression/authentiques dash stips in they are niticeably ligher than the silver pained ones lol.

what else is ther in your car to lose appart form going with carbon fibre body panels.

 

[R20 CWH]

i love these weight saving mods, next it will have 3 wheels :rasp:

 

[Jaff]

cling film rear windows FTW lol.

Sadly very little.

As before passenger seat and airbag next...but apart from that there's not a great deal that the car doesn't need.

Smaller battery maybe, lighter suspension possibly, but after that I'll be adding weight again with a cage

Yep. Which is all any of us have to go on when talking about car performance after all.

what mods do you have?
what weight will your car be once the seats are changed?
I ask because Id love the magic 200hp / ton in my ph1 172

going to aim for 925kg and 185bhp personally
