I run no PCV and VTA on that side. I run a baffled catch can with stock routing on the VC-->intake pipe. No issues here - 9 turbo with many miles and many hard miles. No failure. I believe maintaing the intake "pull" is beneficial under high rpm situations to properly vent the crank case. Many have been successful without it though.

 

I've only used it on one setup. Had a breather filter on the valve cover on one end, then on the other end of the valve cover it had the line run to a baffled catch can. From there, another hose ran down to the valve.

This was on an MR2 with basically a downpipe and then a muffler on the end. The slash cut went right before the muffler. Smoked on decel and occasionally under boost. Not terribly bad, but enough you could see it easily. The motor didn't smoke before that setup.

My friend had a Celica all-trac. It gummed up on him on a long road trip and stuck open and then I think it caught on fire. Didn't damage anything, but fire is never good.

 

True they saw a demand for larger stock frame turbos and boom look at what can be done. I make NO quick decisions when its time to upgrade a major part ( like a turbo). I did look at FP turbos and CBRD. I did NOT like reading how long they took to do the work and I read on some of the failures. I went with the new and for the most part untested BBK full. Thing has been FLAWLESS, and on all my engine upgrades from 2.0 to 2.3 and now my 2.4. The 2.4 runs it out of breath in the upper RPMs thou.

 

hey any updates from FP?

 

could it be that all bigger journal bearing "stock like" turbos are weak by design? same thin center section, larger wheels = fails sooner rather than later...

 

yeah, this one takes the cake.

blaming VTA crankcase on failed turbos. I have heard it all now. Thats about as stupid as it gets.

running recirculated is about as stupid as it gets as well. there will be oil in the line no matter how good your catch can is. you dont want oil in the intake. kills intercooler efficiency in a heart beat. oil in combustion chamber also very bad stuff.

 

Pulling a vacuum on the cranckcase at all times, especially at boost, assists oil movement. An open system does not allow this lower sump pressure while boosting

 

we all agree with that, but the downsides outweigh the positives. if you have good ventilation to keep pressure from building up, it is 100% fine vta.

 

I HIGHLY doubt you are pulling any kind of a vacuum and I'm sure even if you do manage to get a little, I doubt it's enough to do anything over venting to ambient with proper sized lines/breathers.

I haven't tested it with a turbo inlet pipe, but I have tested an actual mechanical vacuum pump, and you are right, there are gains to be had. But it takes a vacuum several PSI below ambient to see anything. Even at that, the available gains come more from being able to use lower tension rings to reduce friction.

 

EDIT: It was not a DBB FP BLACK it was a JB and I did buy it rebuilt Second hand... Sorry for the confusion. I am currently trying to get this resolved with FP and Understand the risk of buying second hand stuff....

 

Well im runnin a recirc Cusco oil catch can for past 50k, no issues my fp red has about 50k....only reason I could see a vta catch can cause an issue, is depending on location of catch can, if the catch can fittings and hose ends sit higher in the engine bay then the fittings on valve cover even with the force or the crankcase pushin the pressure out it might not fully exit the valve cover....kinda like pinchin your straw partially then tryin to sip it, compared to normally sippin it. So i would assume as long as you have the proper an fitting and hose size to accomodate your potential positive crankcase pressure....it shouldnt be an issue. Imo.

 

sorry to hear z32cctx , warranty on jb black now that s a novel idea .

 

Just my Opinion on early turbo fails.....if balanced right the bearings would last you quite some time. Does this increase cost...yes...but still cheaper then a new turbo.

i have been trying to figure out what kind of turbo i want to go with for my goals, and lately from what i have seen, im convinced stock frame turbos are not going to work out for me. im not a fan of spending 1500-2500 dollars every 12k miles. i also am not looking forward to b.s. excuses everytime there is a failure. lets face it, when you blame a catch can, its time to move to another company. sure they have had a lot of success, but can you take a chance that you wont get that b.s. excuse if it happens to you? is your money that frivolous to you that you can just blow that kind of cash, have the turbo malfunciton and then get that excuse on the phone?

i personally think people deserve better for their hard earned, but apparently from what i am hearing and seeing, fp just isnt concerned with providing a genuinely strong product to their customers, and more interested in coming up with new things to blame

whats next? "oh you have a jdm squash air freshner? yeah, im afraid that caused the failure, we cant warranty this, the scent fumes got into the air filter and caused the compressor wheel to fill with lemony freshness and created an unbalancing situation of the impeller cartidge."

im not an engineering major and all that but this is ridiculous. all the b.s. i have been hearing about fp with the zinc oils and all this other stuff, the catch can takes the cake.

 

@rick1024 lol....words I don't have them. I'm not trying to start a forum war here but...this is a ridiculous thread/comment(s).

I had a failed FP black, one of the first actually. FP is a great company, fixed it no questions asked.

Fast forward, and I was one of the first with a DBB FP Black. It's been running strong and I've had no issues at all. 34 PSI boost and many, many miles.

The original JB units were fine, unless you over-spun them. Think of it like overclocking a computer, you keep upping the voltage so you get more speed, until the processor does not accept any more voltage and it pops. Same thought process can be applied to that of a light bulb. You can apply 24v to a light bulb in order to get it grow brighter, but it was only built to accept 12v. Same thing with JB stock framed turbo's....they can only accept so much until they blow.

What we don't know is what happened during @z32cctx's tuning process. What was the boost level? Timing? Fuel used? For all we know he may have had a boost leak that caused the turbo to over-spin to make up for the loss of boost, causing it to fail.

With that said, the ball-bearing units are FAR superior to their journal-bearing counter parts. Think of the older journal-bearing units as Windows 98 and their new ball-bearing units as Windows 8, big difference. Just like computer operating systems, turbos advance with time.

And yes I would recommend FP to a friend.

Anyways, enough rambling....Happy New Years!
