HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

If using a hydroboost system with a manual steering rack how do you plumb the lines? It looks like the power steering box could be replaced by a cooler or reservoir. Is that correct?

In my set up we have the Turn one pump, Ford Mustang GT Hydroboost Brakes, Sterring rack, filter, cooler, reservoir. It would seem like you could just remove the PS rack from the flow route.

There might be a pressure adjustment that has to be made, I will let more knowledgeable people talk to that.

I have the manual hydroboost with manual steering. You need to get a fitting for the power steering side and convert it to to an an fitting. Brake the opening closed and dirll an oriface. I can tell you the opening size if your interested and then (what I did) is plumb it into a transmission cooler then back into the reservior.

Thanks, that is what I thought. Did you mean braze the openening closed, not brake? Will the stock LS1 power steering pump produce high enough PSI or is it necessary to get a new pump?

Turn One told me that to function for hydroboost, the F-body PS pump needed to put out higher pressure, but that the volume remained the same.
The Porsche rack also expects higher pressure. So essentially, it's the same mod whether for hydroboost or power steering on these cars.

Which leads to the question--if you're going to run hydroboost, why not run power steering as well?

Sorry I was tired, yes braze. My stock LT1 pump can keep up and since the BMW setup only requires about 500psi your better off using the stock one.

Oh yeah, sorry...i should mention that my information above was for the Mustang GT hydroboost and the Porsche rack. Sounds like the BMW system requires lower pressure.

Well, I already removed all the power steering lines, cooler, reservoir and canablized it to make my manual rack fit late offset. The first part I bought was the dual master cylinder mount and the plan is to run a manual rack and brakes. I am just planning in case that doesn't work out.
