I am looking at a couple of things.. I am talking to this guy and he has a Greedy BOV that can be set up to blow off or bypass boost. What do they mean by Bypass?

Also... I think that my turbos wastegate is directly on it. Would it be possible for me to get another turbo without a wastegate?

Do I need a wastegate? Isnt the BOV already protecting from overboost if the pressure builds to high?

Thanks

You got alot of research to do before you go buying the things your talking about buying. Your wastegate is on the turbo which is connected to the manifold because its "Internally Wastegated" like the SRT-4. You have to have a wastegate thats just how it works. :lol: . In order for you to get a "External Wastegate" you need to get a new turbo and a new manifold.

As far as the BOV before you buy that make sure they make an adaptor plate for your car, because if they dont then its going to be use-less for you.

Why are you wanting to do all this to a Volvo? Why wouldnt you get the car working right under factory specs and just drive and enjoy it stock. It sounds like with your knowledge you'd be alot better off in the long run.....

yes... I dont know shit about turbo components... I know how they work... but eh...

as far as me doing this. I want to do this to rid the car of issues. The car is having alot of "turbo" related issues that is costing me precious pennies. So i figure is I just buy a new turbo, BOV, and all the othe needed components... Everything would be new, and thus the turbo issues gone.

Why not do all this to a Volvo? They are expensive to repair I know, but their safety, and performance is awesome. Besides... not everyone has a modified volvo 850T5. :thumbsup:

Its the gratest family sleeper. Its happens to me all the time, a ricer pulls up with his hot ass gf in the car, and looks over at me with all that baby shit in the back of my "family" sedan, then tries to smoke me.

I just love the look on his face when he is there hitting vtec, and im just tagging along listening to Jazz hahahaha

Its even better when when I switch to sport mode, and watch the look on his face when the turbo spools nice and loud while I rape away his ego. ::sigh:: I have alot of these stories to tell.

So moral of the story... It excites me to want to drive around in the family sedan, and if the car dosent look fast... I dont have to get that "safety" lecture from the wifey.

Edit: Thanks for telling me about the internally wastegated thing... Which brings me to another question. What is the benefit of having an internal wastegate, rather than a stand alone? Thanks for helping man.

As far as the pros and cons of an internal wastegate vs. external wastegate I'm really not sure. Maybe someone else can chime in, that knows.

EDIT: I'd suggest trying to find some Volvo fourms and talking with some of those guys, Im sure thatd be more then happy to help you out and set ou down the right path as far as your car goes.

Thank you sir... But I think that I should just let the pros handle this. I called Independently Volvo (thanks David) and I have an appointment for tomorrow.

LoL O.K. what is it that your trying to do? Replace the turbo and use a external wastegate? Internal wastegates only let you boost certain amount depending on the wastegate which you would have to use a boost controller or just run the turbo off the wastegate and see whats max boost for your wastegate. Extarnal wastegate is more flexible and allows you to adjust the presure by a screw that have on the top. The o2 housing on some turbo allows you to use External/Internal wastegate but External wastegate are mostly for the big toys. There are tons of different turbos out there which makes you think more then twice. Now as for a BOV if you planing for this volvo to be your "badass" car i wouldn't recomend the Greddy Type-S Bov. Why? Different people have different isues with them, some say they start leaking at 20psi other say 22psi but if your going to run high boost on this car chances are is going to leak. So just go with a HKS ssqv or a Tial Bov. Also, just an advice if you dont have big plans with the car just keep it internally gated and you'd be happy so will the car ;) . Just keep in mind that turbo cars are 1:1 fuel presure, as boost increase fuel presure also increase. SO if your going to boost a few pounds over stock you might be fine, or experience a horrible Fuel Cut and even lean out your motor and destroy it. Or you can buy a Walbro 255lph Fuel Pump if they make a High Presure one for your car get it, some injectors and you'd be good to go and happy.

Suggestion, just run a Vaccum test and determine whats leaking, and where it's leaking. therefore you know what it is and where it comes from and u can fix it your self without having to pay anyone. Just remember it can leak from any where a crushed Intercooler, from a copling on one of the hoses, from a bad weld, from the BOV or maybe even just a vaccum leak from a broken hose or anything like that.

Thanks for the info... you answered my question.

However, I am not building a monster. I want to keet the boost where it is, or if anything up it a little bit, like 2 lbs or so. I am not sure what I am running because my boost guage is stock, and it has no numbers on it.

As far as why I was going to just change everything is because, I was having issues with the turbo to begin with. The car would bog out on high boost, or it would just not boost at all, and constantly be in vac.

Dealer replaced a bunch of hoses, and shit, and found nothing. So I took it today to the volvo place, and told them to fix it, and if possible, up the boost a bit.

what is your "turbo related problems" ? yes external wastegate will control the flow better but only if it has a prioritized location. most of the log ( cast manifolds) don't have a prioritized location for the external wastegate, so many of times the internal type are better, in certain cases.

ahh, musta skipped right over that. it very well could be the wastgate, if the dealler has already changed the vac hoses and control soliniods. or the only other thing would be bearing's going bad.you could take off your intake to the turbo and grab the shaft and see what kinda movement it has, up and down in and out. how many miles are on the oem turbo? i'm sure the dealler felt to see if there where any manifold our exhaust inlet leaks, i would think anyway's. you now netics makes some turbo upgrades for those manifolds

two psi over stock is nothing. you can probably do a little more then that. Also, remember the stock boost gauge is a "TOY" dont trust that shit!! If you need a Autometer boost gauge let me know i have one 30/30 ill let it go for cheap since im not going to use it any time soon. Yes, like dave said (i think thats his name?) take off the intake from the turbo and put your finger on the center of the impeller and try moving it to see if it has any play. Seals or bearings might be bad. Best thing to do is do a vaccum leak test. Also, just remember that internal wastegate controls the flapper on the o2 housing. If the wastegate has dirt or anything on the inside, curruption or w/e may be be stock and might be keeping the flapper open at all times causing a boost leak.

Good Luck!

Unless you dont want any tuning done to the car or what not 2psi is fine.

Also, keep in mind what AJ said on the last thread about External and Internal wastegate. If by any chance you tried adjusting the actuator rod on your internal wastegate you probably left the flapper on the o2 housing opened. To check weather is open or close, you would have to un-bolt the down pipe from the o2 housing also this method can be used while adjusting the actuator rond he also had a good point about external wastegates. some wastegates are adjusted by a spring or a series of springs with different tension to allow you different boost. Other wastegates uses a single spring and a screw at the top of the wastegate if you tighten it creates more tention to the spring therefore allows higher boost. other external wastegates uses both methods.

Shit, sorry i keep replying lol. Im mistaken by telling you that the flapper controlled by the Actuator Rod is on the o2 housing. IT IS NOT!! The Flapper is on the Hot Side of the turbo. right before the o2 housing. It Goes Hot Side --> o2 Housing --> Down Pipe.

I've never seen an external wastegate that had an adjustment screw on it. Springs don't control how high the boost level you run, they determine how low you can go. My spring is the standard 10psi Tial spring, I've run 25psi before. Something about a boost controller or something, I dunno. I don't know anything about volvos but I do know about turbos. If your car is MAS air and you aren't maxing the fuel system already adding a few pounds of boost isn't going to cause you to run lean and destroy the motor. If the car is a MAP car you will have to make fuel and timing changes for anything you ever do to the car. I would suggest researching on a Volvo forum before you do anything.

Because you probably never had a Turbonetics external wastegate, but if you want i can show u one ;) got pics.

Well I got the car back. Its running great. Changed the BOV. Car is on 8lbs. I asked what I would have to do incase I wanted to get the boost up, and he said that I had to turn this little nob that located under the hood, and he showed me where. He said that he doesn't recommend that the boost goes higher than stock untill I change the oil pump, water pump. Timing belt is almost time to change too. Then I can go as high as 10 with the stock ECU running 93 gas.

As of right now, its ok that I use 89 as long as I dont plan on going in long hwy trips, or high revs.

Car is great. Solid. I get max boost at 3200rpm. BOV sounds awesome. Instead of a long burst, I get like a bunch of little ones, at a nice low volume. Turbo is nice and loud when I open the throttle wide.

Feels like new. Thanks for everything... I feel a build coming soon with this car. Im already thinking on a complete teardown, and rebuild, with new turbo, K&N filter, 3 inch exaust, S80 rims with 205/50/17's, and a Big Brake Kit with porsche calipers, and a 1 inch drop. Maybe some light tints to help control the sun, and a couple of BABY IN CAR signs. :Evil face:

glad to here it man, so it ended up being the bad bosch valve, very comman on the vw's. at least it was a cheap fix. i wouldn't run 89 though, don't take the chance. as far as that goes the dyno should be here in about 2 weeks if you want to run it and make sure the air fuel ratio is good let me know. congrats

Thats awesome man, good you enjoying it. Like Dave said, dont run 89 use 93 for maximun performance. If you need any help or have any questions here we are.
