To much oil pressure

[TalonspoolAWD]

I have a AGP turbo on my car. IT is a RS49. I am oiling it from the filter housing and i am reading about 20psi at idle and as soon as i crack the throttle it jumps to about 90psi. I talked to AGP about a restrictor and i was told to use a nitrous jet. I went to a local shop that builds hoses and has fittings and they told me a few things. They had a adjustable FLOW CONTROL valve that would fit off the oil filter housing and there is a locking knob to adjust how much goes through. The guy told me that restrictors would not lower pressure just flow. I dont see how a restrictor would lower pressure either because your making the let smaller and it would increase pressure. I am just wondering if i choose to buy this unit if it is a good idea. I tried blowing through it and as i srewed the knob outwards it would allow a little more flow slowly,BASICALLY A ADJUSTABLE ORFICE. People say that a restrictor or adjustable orfice would lower the pressure and volume, i dont see how thats possible because looking at that equation PV=C (Pressure,Vollume=CONSTANT or a #) if you were to increase pressure volume would decrease. If you were to increase volume pressure would decrease. Basically if 10*6=60 to satisfy that equation 6*10=60 the 10 being pressuer in the first case and the 6 being pressue in the second. MY turbo is smoking when i rev the car up due to haveing the gauge jump to 90psi of pressure, i elimintated the Balance shafts too. I just cant take seeing the smoke anymore. Should i put a adjustable restrictor in or am i going to have to buy a regulator to regulate them. A restrictor will only lower the volume. I was wondering if anyone had ever even put a guage on there car after installing a restrictor. I do NOT WANT TO BURN THIS TURBO UP. AGP says nitrous jets but they dont know what size. I cant get a adjustable flow control which is the same thing. What should i do to keep this thing from smoking.

I'm kind of having the same problem with mine but I do not have an aftermarket gauge to tell exactly how high the pressure is climbing up to. Only thing I can think of right now is perhaps our pressure relief valve on the oil pump cover assembly is getting stuck somehow. I took mine off last weekend and there was what looked to be DIRT particles in it, so I cleaned it up and re-assembled . . . but it didn't help. (perhaps I didn't clean it well enough . . .)

Mine is around 25 at idle, and 90 psi at 3500k cruising.

The adjustable valve will work it is going to let a smaller ammount threw in to a larger pipe on the other side lowering preshure ..

Are you sure about this cause were talkin a $800 turbo thats brand new

 

[Defiant]

Press AGP for a specific answer. It's their product, have them tell you how to set it up. $800 is too much to cowboy around with.

Don't get all scientific about the orifice thing. It's how it's done.

 

[TalonspoolAWD]

i am not getting scientific, its just what would happen. One thing increases the other has to increase, there indirectly proportional. I talked to AGP and they said try nitrous jets, start with a large one and work my way down, I DONT KNOW WHAT KIND OF ANSWER THAT IS, TO ME ITS A LOUSY ANSWER. THE FLOW CONTROL IS A ADJUSTABLE ORFICE, BUT LIKE I SAID, ARE WE TRYING TO LIMIT VOLUME OR PRESSURE, ONLY ONE CAN BE DONE WITH A REGULATOR.

Using a NOS injector should work. Only the side of the injector that is getting the pressure from will be high still.

The small orfice will be shooting oil into a bigger opening, causing that area on that side of the injector to not be as pressurized, as long as the hole for the oil to exit is as big, or bigger.

Am I making enough sense? If not I will try to draw a diagram or something.

 

[TalonspoolAWD]

i understand what your sayin, does anyone know what size to use, cause i can get this orfice that is adjustable also.

I would try the adjustable one, it would just be much easier. Also where are you measuring the oil pressure from?

 

[TalonspoolAWD]

my oil pressure is measured off of the filter housing that my turbo is feed from. THere is a T inline half goes to turbo the other side to my gauge.

Hi,sorry to drag up this post but it is suddenly relevant.I have an rs49 just installed it.As per their instructions took oil off the filter..pain in the butt.I have big clouds of oil every time I floor the car and my turbo is putting out no boost at all,maybe a few pounds.This is the first day had it running.I bought it last oct or so but didn't install it till lately ,had to get supporting mods.
My car ran ok with the old 14b and didn't blow out in clouds out the back.If this is in fact true AGP better send me a restrictor jet.They had zero instructions with their turbo.I had to hack the factory fan big time to get the turbo in my car and the lower intercooler pipe is kind of crushed in there now.That is not big deal but whats up with this crap.Why do they recommend the line and filter feed if it dont' work.This is crap.I have a call in to them and
email.
Also can blown head gasket cause oil in clouds out the back or just water..will the turbo boost with blown head gasket.Although again my car was ok with the old 14b.And how can I blow the headgasket with no boost.It might get three or four pounds but the oil cloud is embarrassing.
Also all the rings can't go at once and then give zero boost.The turbo will still boost with worn rings won't it..
