Nobody mentions filter(s) on low pressure return line, why?>>>
Filters are debatable, change fluid at least annually they are just something else to go wrong. If you collect a lot of garbage in that rotation there is something else going on that a filter may prolong but a case like that needs to be investigated, not covered up.
<<<Saw at least one mention cooler other than radiator, why not more thoughts, Heat Exchangers, chillers, etc ?>>
Factory GTOs use a separate, stand alone "cooler" on the return side in front of the radiator. It is in essence some fins welded to the return line and just this side of absolutely worthless. The only practical purpose it serves is to fill the gap left in the line if you cut it off and threw it away. Using the radiator (assuming you are referring to the a/t side) would be the definition of over kill. Any piece of equipment that transfers temperature from a source to a receiver is a heat exchanger. If there is one thing that might beat out the radiator for over kill it would have to be a chiller.
<<<I am tired of keeping engine clean and sparkling and then seeing or knowing diarrhea in reservoir, am I alone on this?>>>
<<<No mention of reducing heat soak, move battery to trunk and get OTRCAI intake. There is oem outside air intake in oem original air box! Mod the battery area (open up a air intake there).>>>
DUDE- THE TOPIC IS OVER HERE......
<<< What is temp on P/S fluid?. I've seen alternators with fan working from pulley, how about P/S pump with fan,>>>
A pump that may benefit from a fan would explode before you got to the street or so large you'd need a second GTO to carry the pump and third to carry the fan around for you. System pressure peaks reach well into the thousands, clean fluid is not compressible therefore the pump must be strong enough to take that hammering. You would be surprised at how little is inside a PS pump, 80% of one is the casting itself. Oh and adding a fan would also add more parasitic loss to the accessory drive system, it takes power to turn one.
<<< A/C uses clutch logic - can this logic be applied to P/S pump - activated when we turn steering wheel.>>>
That would work if you could get the system to anticipate every move and start before you do. The fact is the system (provided the car is not sitting still, the engine not running, there is no fluid or the belt is off) is constantly loaded just keeping the car straight even though you don't feel it. Attach a digital gauge and log it, it never flat lines. If you drive a vehicle without power assist you will appreciate what an assisted system does other than make it easier to park.
<<<Anybody ever try doing any of this? If so, pls share, I never re-invent the wheel unless I am sure nobody has tried to before me.>>>
There have been attempts at electronic steering, there have been attempts at 4 wheel steering, there were also better than 125 attempts on Hitler's life. Some things just don't work out. I'm pretty sure the wheel as we know it is safe for now.
<<<Reason I ask is my builder will be pulling my engine and trans out shortly for mods, bolt ons and whatever other crazy stuff I want done>>>
If that is the extent of your plan for the engine you should leave steering alone.
<<<or he wants to try.>>>
If you let your builder experiment with you engine you should go back to steering.
<<< He used to own title of Fastest GTO in SC. Well someone beat his time (I showed him link).>>>
And because you can't put anything on the internet that is not true......
<<< Well supposedly he spun a bearing and flattened a lope on his cam,>>>
At the same time? Does that mean his idle smoothed out? And you let him turn wrenches on your ride? Why don't you ask him the steering questions?
<<<That's the story he gave me, IMO he is doing whatever it takes to regain his title again. I am proud to be his buddy and hopefully soon his friend also.>>>
You can't really be one without a whole bunch of the other.
If you go to a professional for any kind of service work (not just automotive) try to keep it at a professional level. If you go to a buddy don't be surprised if he is full send it John Caridin when an experiment goes south.
