Anyone ever heard of a turbo freezing.I went out early this morning to drive my 94 turbo wagon and it would'nt make any boost.It was below 0 this morning.It's been sitting in the sun for a couple hours and now it's fine.I thought at first one of my intercooler hoses had come off but they are fine.I've got new silicone hoses so I dont think they are collapsing.Anyone have any thoughts?

 

i'm gunna say it's normal? cuz the car is solid frozen
not gign to lie i'm the same, you have to warm your car up first, i've driven my car waking up in the morning with the car being at -13 degress celcius let me just say i'm not expecting dyno numbers in that weather, the car performs HORRIBLY straight from cold...

 

Do you have the stock reverse intercooler setup?
If so then yes it is common that is why Volvo did away with it.

 

is there a way to "unreverse" it?

 

You can get the necessary pipes to run the normal intercooler set up, probably get them all from FCP.

 

Or go to a junk yard and pull them off of a junk car.

 

how do we know which way all is hooked up now? what exactly is the diffference to be looking for

 

If it is the old style it looks like the RIP kit alot of places are selling.

 

ooh... I think some of you are misunderstanding Tech... some early 1994 Turbo 850s had the intercooler piped in reverse from the factory... the original design was in the top, out the bottom, like some of us have paid big bucks to get... They then recalled those early cars due to problems with that setup, and the fix was the convoluted intercooler plumbing that the late 94-97 850s come stock with, as well as the 98-00 S/V/C70s. So if he has one of those early 94 850s, he actually needs to go to a salvage yard and get all the intercooler plumbing off of an 850 with the "standard" setup to fix his problem.

 

so why is it a mod to do a RIP kit?

 

Because the current set up has the piping from the turbo entering at the bottom of the intercooler going to the top, the RIP enters at the top and going to the bottom. It is believed to be more efficient going from the top to the bottom, mostly because of a thing we know as gravity. But, IIRC, they had problems with oil going through the hoses and then traveling down the intercooler, kind of mucking it up. The set up now leaves the oil at the bottom of the intercooler where there is a drain to drain it out and fresh air coming out the top.

For the most part, adding the RIP kit doesn't give you noticeable gains, it's more so for aesthetics, although with supporting mods and what not, if may be more effective. Before I would ever do a RIP kit I would go for a FMIC, more effective for those running their cars harder.

However, the current set up/intercooler is pretty efficient, as tested by IPD, and is good up to 350 hp I believe.

 

I have my intercooler frozen very often when outside temp drops below -10 C.
Can you put a scheme of intercooler and how it can be updated?

 

I will see if I can find one.

 

krs2 and irmantas855,
make sure your intercooler drain hole is not blocked....so it can drain out water and condensation. you can also remove the bottom intercooler hose to see if it has ice. google any online parts store for "intercooler" and you will get a diagram of where all the hoses connect.
