No really experince with them.....They should flow better then stock. maybe even have more surface area which is what your are ultimately achieving, by going to a cone. If you go the panel filter route, you will definitely want to add a forced injection hose for more air..... that will help a stock box a lot. there is also that little shield blocking the tube in the front of the car, where the stock box gets it's air from.....I see some guys cut it to force more air through the opening.

 

You mean where that hose kind of bends down, blocking air straight on and forcing it to shoot up the hose? I think I know what your talking about. I was thinking about even trying to find a fitting that I could put on there that would be larger and have a little bit of a scoop to it to force more air into it.

Cool, Thanks. Nothing hard about that. I'm guessing that makes a pretty good difference.

 

They fixed that on the 850. It's intake faces directly forward.

 

Not on mine it doesn't, maybe it's something they changed in '95, but that's how mine looks on my '94. I think Volvo did a couple changes to the engine between 94 and 95.

 

What is the stock boost on a Volvo 850 turbo?

On the forums I have read it is 7-8 psi and other places I have seen 9.6 psi.

 

I think it's the 7-8, That's what I remember reading.

 

Apparently the T5-R's could do 9.6 psi and since I have a T5-R ecu it worries me that I'm only boostin' 7-8.

 

Shouldn't you be boosting whatever the ecu says, I mean the 850 turbo and the 850 r have turbos. If they ecu says about 10 then you should be boosting about 10.

Where did you get the R ECU anyways?

 

It is actually a T5-R ecu and it was bought off ebay. You should boost what the ecu says unless you have a leak or some other form of error.

In another post I explained how I currenltly am not boosting what I was at the beginning of last week due to some kind of leak. At the beginning of last week it was boosting 7-8 psi and I wanted to know if that is stock.

I just want to know what the T5-R should be boosting so I know what to shoot for to get my car back to stock pressure.

 

OOOOHHH. Ok. nevermind then, sorry about that.

I'm trying to find either an R or t5-r ecu, but I haven't had any luck. How much did you pay for it?

 

About $100

 

Not always true my Yellow one was only boosting 7 PSI and should have been 10 according to Volvo. No leaks or anything.

 

So tech if I get my inmotion ecu done do you think I will only be getting like 12 psi instead of the 15 they set it at?

 

What you order is what you should get. If they say 16psi your boost gauge should read 16psi. Unless they are reffering to boost spiking at 16psi and say you only read 15psi.

if anything else, get a MBC or EBC like tech did and controll boost that way.

 

You should get what it says unless you have a leak.
