Adding Hydro boost, P/S pump?

[bohochg]

I'm adding Hydro Boost to my 71 Charger brake system.
Will my stock power steering pump be adequate?

Already upgraded to Borgeson steering box.

Don't no much about Hydro boost?. Why not just a PS cooler?

Hydro Boost is a Ford design that uses Hydraulic fluid from the power steering pump instead of engine vacuum for your power brakes.
I don't know what stock pump you have. I imagine if it was a disc brake pump it may be adequate.

The pump should be OK if it operates properly now. I would recommend adding a cooler for the system.

I have it newly installed on my 70 duster and have it for many years on my 66 Satellite. I love it for a huge cam that creates almost no vacuum. It makes for a very easy pedal. The only down side (beside a bit of extra weight) is there is very little feed back before brake lock up, But you just get used to it and it's never really been a problem. My Satellite traps at 136mph and I can easily slow the car down to grab the exit @ 4050 lbs, 4.5" skinnies and, willwood discs. I think the biggest issue with the stock box is that if its a older style Federal pump, the hose fitting are next to impossible to find. If its a Saginaw pump its much easier. Borgeson sells the correct hoses for the Saginaw pump but not the Federal. Any stock or aftermarket Saginaw pump will work.

Not the point at all for the OP, but now you got me thinking....i always thought that was a Delco Remy creation. My first experience was a '74 Chevy cube van, but i know they had other applications prior.....
My dads 84 MarkVII did have it too.


EDIT.....looks like it was Bendix, all the way back in '68.

Hydro boost is a similar set up used on many medium duty trucks above 1 ton, they are also equipped with a electric back up pump motor in case of engine failure. GM/ Ford/ Ram all have pretty much the same set up and it has been use for many years. There is plumbing ,space and weight to be concerned with as well as the correct pump. Pretty expensive way to deal with a large cam and have poor pedal feel. Just my opinion.

And dont stall the engine, because you dont get one or two free assisted backup pumps of the pedal like you would with a vacuum system.

The hydroboost systems I have seen do have an accumulator cylinder to allow for a small amount of reserve boost.

According to a rep from CPP I talked to at the SEMA show a few years ago, HB needs at least 3gpm and I think it was more than 2k on the psi. You need to be able to operate the steering and the brakes with no pressure or flow loss. Check in with the supplier. This company is supposed to be knowledgeable on the subject.

Saginaw pumps don’t put out that much usually so I think that guy may be wrong.
Saginaw pumps have been used in GM trucks with hydroboost.

 

[ckessel]

True but the spec's may be different between non HB and w/HB. Something to look into.

Would I add the cooler to the pressure side or the return side?

Return side.

My car has a factory cooler on the Saginaw P/S pump.
I'm going to put a gage on the pump to verify pressure.
I'm not going with a purchased conversion kit.
I'm building my own system the help of a friend who built a system for his big block Chevelle.
I'm reusing the original master cylinder.
With the reman. hydro boost pump, lines, & fittings I'm all in at less than $400.00.
That doesn't include upgrading the P/S pump & cooler, if needed.
I've machined my own firewall & master cylinder adapter plates.

I'll post what my stock P/S pressure is.
