I was wondering how hard it would be to drive to the staging lanes and then stage and run the 1/4 and then turn off the track back into the pits with the powersteering bypassed? What would I gain in the 1/4 mile? I have heard as much as nothing to .3 secs????? I have no smog pump so I was thinking about routing the belt like in the the pic below:

 

Driving w/o the PS is difficult, But I did it for literally 3 months because Im a Lazy poor *** .

AS far as power gains, Nothing worth the effort of Heaving the Wheel around and risking breaking your steering colum (ask Me how I know)

I belive some Dyno Tests Have Shown about 2 Hp gain From removal Of the PS pump. Your better off skipping breakfast.

On the PLus side, It did wonders for My Lats. Seriously.

How do you know! You knew it was coming.

Why was the AC still connected? The engines that I work on need 40 ft-lbs to turn the accessories at idle. That's AC PS VAC ALT the list goes on. Moral of the story no accessories = 40 ft-lbs. You don't even need the alt connected if you're just running 1/4's

The hardest part of driving with no PS is gonna be staging. Getting it lined up will be a fight as you won't be moving much.

Now here's a fact. On my 85, i tried no PS for a few runs one night. Net result, no gains in ET or MPH. NONE.

Now the science...why no gains? Simple. The PS pump is basically along for the ride when you are going in a straight line. Hydraulic fluid isn't going anywhere, therefore the pump doesn't do much work.

Any gains you hear from someone swapping to manual steering can be attributed to the weight loss, which is significant.

First of all... Many older cars don't come with power steering at all... therefore driving without the power steering connected will be very doable.

Second of all.... thats cheating anyway. You might get better times out of it, but you want to know what ur car can do in driveable street form right? I mean... if you are racing a Mustang on the street on your way home from work, you will have the pwoer steering connected then... so dont you want to race the car that way?

Anyway, if u must... you might as well take the AC belt off as well while ur there.

First of all, cars that did not come with power steering come with completely different steering boxes with MANY more turns lock to lock than a PS steering box. This is so it requires less effort to turn the wheels (just like gears in your rear end, and why 4 and 6 cylinder cars often come with much shorter gears than V8 versions of the same car) Also, not many cars w/o PS have to turn 2 nearly 10 inch wide tires with nearly 60% of a heavy cars weight sitting on them.

I'm not saying it isn't doable, it will just be VERY difficult. When i ran my car w/ no PS i was only running ittle 215/65s on the front, and that was quite hard enough thank you. Unless circumstances demanded it, i would not drive one of these cars with the PS disconnected again. This is entirely different than converting to manual steering by swapping to an S10 steering box, which will have more gear reduction to aid in turning the steamrollers..

 

How could you possibly test this?

 

Dude, you could probably drive around town without powersteering.

My little red '85 S-10 does fine, it lacks power steering AND brakes.

 

you answered your own question...

"would not drive one of these cars with the PS disconnected again"

there you go.

 

These bastards are amazingly hard to turn at all without the powersteering. At low/no speed it's almost impossible to turn the damn wheel. Rolling around the staging lanes would be pretty hard...

Huh? I never asked a question. I was just pointing out that even though there are millions of cars that have been produced w/o PS, that does not mean that driving a thirdgen with the PS disconnected is reasonable for the average person. It's not my opinion, it's fact that non-PS cars get an easier to turn gearbox on their steering, which is a completely different animal than trying to turn a quick ratio box made for PS. Can it be done, yes. Will he get agreat workout, yes. Will he see any gains from the struggle? Probably not, as i said in my experience, disconnecting the pump made no difference.
The 85 S10 example illustrates my point, there are many S10s that don't have PS, and the non-PS steering box from an S10 will bolt right into a thirdgen, and makes it a much more manageable task.

I was just realting fact and my experience, not just anecdoatal evidence that it can be done.

ps, my beater 86 corrolla doesn't have PS either. And even that super light car with freakin bicycle size tires on it it requires significant effor to turn the wheel, even though the steering gear it uses has at least twice if not more the gear reduction of my camaro.

 

I've removed my p/s a long time ago and have had no problems driving around. When your at the strip you bump up the pressure on those front tires anyways, that makes it easier. so it's really not that bad, staging or turning on the return road.
