High rpm Power Steering whine

[SR71-SVO]

Hello all i have a question for anybody who can answer does anybody know where we can get a better power steering pump,maybe better pullies or something.The reason being i got my car out the other day and raced a z28 camaro and when i got home it was making this god awful noise no it is not low on fluid and no it is not leeking.Ever since i got my essy head on it i redline at 7500 that is what i figured hapened to it let me know what ya think thanks jim

ford power steering pumps have always wined -- ocasionally you run across a quiet one but most are noisy.

under drive crank pully?

I guess you could somehow fit a Honda S2000's pump into the SVO. They have a redline of 8,000 rpm.

I think you will have to make a custom unit to get what you want.

I just killed the power steering pump on the 300zxtt that my friend got. The ecu that it has does not have a rev limit on it. I saw 8200 rpms and it was still pulling.
Custom pully from Ess. and a new pump would be my guess. I think they have them.

IMO, all the pumps whine. The louder they get the more likely that its on its last leg and the wheel will start getting "jitterry" soon enough.

Just some food for thought, but if someone was looking to underdrive it...I wonder if there is a slightly smaller pulley from an older ford with the dual belt set up and press on style that would work.

When I looked into making an evac pump I searched the yards for older F-150 /E-150's for different size pullys.

By the way Jim, next time you start a new topic, could we ask that you out the problem in the title of the thread ? Helps us out a bit more. ( For Example: maybee this thread could be titled "Power Steering whine." Thanks man. )

power steering problem

I will do that gator sorry about that to everybody's response much appreciated, but this is no whine i have delt with whining power steering pumps before and i already have a pulley on the crank i was just wondering if there was anything out there that could handle the rpm's it was a pretty new pump.

(Larger press on pulley would underdrive it)

D'OH !! What he said.

Maybe one of these will work http://store.summitracing.com/defaul...1&autoview=sku

Here is some info I found on the web: "Besides the efficiency and horsepower gains, most stock accessories are not designed to run at higher than stock RPM's. For instance, OEM power steering pumps have been known to self destruct in racing applications. At a certain RPM the internal bypass becomes restrictive and pressure builds up. As the internal pressure continues to build, the fins on the impeller start to bend, fatigue and then break - there you have it - no power steering."

Or you can always go with a manual rack.

Now thats a good question. I have only see one setup where someone was NOT running PS and I can't for the life of me remember how their belt setup was, except that they were running a serpentine setup.

Anyone have pics or input on how the belt setup would be w/o PS? I guess one could use the early mustang n/a alternator bracket (like I have in my 81, which a 2.3 n/a w/o PS).

I ran a mannel rack for a while. Used the vbelt setup and just cut the power steering pump out of the braket. Smaller belt.
It was a 20 to 1 and 4 turns stop to stop. May go back to it for the street, strip car but not the autocross.

High rpm Power Steering Whine

Thank's again everybody, the thing that bug's me a little is that the pump was making no noise at all not even a little, and now it's like a growling moining kinda noise weird all at once to i have drove it kinda hard raced it once on the track got into a few run in's on the street 3 car's so far 05 gto ,02 or newer M5,and now a 93 or newer Z28, beet the Z28 bad 05 gto tie and about the same with the M5 it started to detonate i had to lift i am not tering it up for the heck of it. The motor really whent lean after putting on that aluminum essy head have to work on the tune a bit.

Underdrive Crank Pulleys

Barry Dean has underdrive crank pulleys for the SVO that might ease your high rpm situation. He doesn't hang out here, but can be found on the Turboford board and goes by the handle Turboalpine (yes he's got one with a 2.3 turbomotor ).

Where can you find a manual steering rack for an 86 and does it come with tie rod ends??
