Glad someone understands

 

It is also the oil return lines and intercooler piping stay stock. The only thing that has to change is the down pipe. And how many people have a stock one anyway. The Manifold is always the most expensive part of a turbo kit. The FP Manifold is as inexpensive as they come and is a cast Manifold which will make more maximum power than a stocker. The funny thing is so many people complain about this necessity for a down pipe which is a huge performance gain with external wastegate boost control and power but have no problem spending the same amount on a stock replacement tubular Manifold which offers far lower performance gains! But it is pretty! And then most of the complainers will spend 450 or more on an O2 housing with a dump. Get your heads out of your butts and realize the SS housing is probably the best advancement for stock style turbos in existence.

 

I got the FP manifold when it was $300, my Megan o2 was bought used for $40. I don't have any bling or anything like that on my car

I don't think anyone is saying this housing is crap. I want for the housing to have an o2 like the old AMS turbo kits that didn't require custom fab. For me I have to find someone who is good enough to keep my exhaust in line since I run the AMS 3 bolt system.

Start from page 6 post 78 and read forward not only do we post our own results but a write up on the same subject from a Garrett turbo engineer and Holset's own white paper on the matter.

Being that our stock frame turbos are one of the most widely used turbos in this sector it's no surprise to see our name keep popping up when dealing with this issue. The majority of people with these BB units on their vehicles never have an issue, but they're not the people who hop on EVOM and make threads about their perfectly working turbo.

but have you seen the prices for the downpipe for the new SS housing? it is like 600 bucks!!!!!! if you're spending that kind of money why would you not get a aftermarket turbo setup like precision which the turbo is significantly cheaper to replace when it goes out compared to an FP turbo which costs upwards of 2K to replace

 

If you're in a state like CA where getting past smog is harder and harder these turbos make absolute sense.

If you like stealth then these turbos make absolute sense.

If you want no more then 550ish (I know some FP blacks have made more) on pump gas these turbo's make sense.

For the rest of us there are alternatives that make as much sense

 

Anyone know why fp stopped making bb turbos for real?

 

Nope it's a secret.

when I read that I chuckled ( because the way it was said very clearly )

 

..

 

Well that sounds like a party, I hope we get invited soon .


Any revisions to the 3076, I am thinking about switching to that. I love the tial VBand stuff.

 

Well i just bought a JB red, new from you guys? so is the secret going to make me regret my purchase?

 

Twas a matter of time before this happened ..

I'm curious myself soo... Xanax for me lol

 

I’ve been quite vocal about my Forced Performance black ball bearing turbo and the oil leak it suffered from new. I’ve been on a few threads on EvoM about this problem and had taken on board other forum member’s, and Forced Performances, suggestions about crankcase pressure and its influence on the oil leaks from turbos. I did the whole crankcase pressure relieve bit, added two -10 fittings to my valve cover and plumbed these to a sealed catch can, with a -12 fitting from this to my intake pipe. This probably cost me close to $300, dash fittings and catch cans don’t come cheap and there was hours of work removing valve covers and baffles, tapping out the cover for two -10 fittings and the 5mm holes, x 20, needed to reattach the baffles. All this work was for nothing because the oil leak was still there after this work had been done and was gradually getting worse. There was so much oil coming out of the turbo it was shooting back up the intake pipe and soaking the air filter. It was also going up my short route cold side intercooler piping, after going through my intercooler, going up a 6” hose to my BOV and was coming out of the BOV and covering my engine bay with oil.

I took my turbo to a local turbo mechanic to get it checked out, and had a look around his workshop. He showed me his dynamic balancer, which spins a turbo up to 60,000 rpm. I asked him out of curiosity if he had ever put a leaking FP BB turbo on this machine, which he hadn’t. I was thinking about the crankcase pressure suggestion and thought that this would answer that question, as the turbo is spun with air pressure from an industrial blower, so there’s no chance of crankcase pressure as there’s no motor attached to the turbo. The machine fires air into the turbo at 6psi and is fed oil at 65psi. After maybe 20 mins he stopped the turbo.

The end result was that just the act of spinning the turbo with 6psi of pressure caused a pretty major oil leak. I’ve added some video’s, one with the turbo just spinning on the machine to give you an idea on how the dynamic balancer works and one (turned sideways) showing beads of oil spinning around the compressor wheel as it’s spinning. I’ve also added a photo of the end result of this test.

I guess what has annoyed me with this whole thing is Forced Performance’s insistence that there is nothing wrong with their BB turbo, oil leak wise. Even after they removed the BB turbo from sale they insist there isn’t a problem, and when asked why it has been removed the best line they can come up with is “Nope it’s a secret” or “it will all become clear soon enough” , jeez, they even added a smiley face!

I know they have been informed about the problem, and I know it’s a lot more common a problem than they are admitting. I feel that FP would not remove this turbo form sale is there wasn’t an issue. They had stopped selling their stock frame journal bearing turbos and from the look of the BB internals, had spent a lot of money designing and tooling up to build the BB turbos, why all of a sudden stop selling them, pricing them at $9999.99 on their webpage.


Anyway that’s it for me, I’ve had my turbo converted to a journal bearing, at a cost of over $1000, and the builder who did the conversion said that there was no visible fault with the ball bearing cartridge. The only suggestion from FP was to send my turbo back to them, at my expense. This would probably cost $300 in postage by the time I had the turbo returned to me and my car is my daily driver, I just can’t have it off the road for the month or so it would take to return the turbo to the states. I also know another Australian FP BB turbo owner who did send his leaking turbo back to Forced Performance for repair, only to install it on its return and still have it leak oil. I guess it just doesn’t pay to be an early adopter of this sort of product, it’s a lesson that has cost me a lot of money, time and hassles.

Guess i should be glad i got the JB version than.... i agree though... something must be wrong for them to pull it off the market. shady not to say whats up though. Even if "it will all be clear soon" basically all that means is, we are re designing the BB and we still want to sell JB turbos in the mean time ... something is up and its smells fishy.
