that crack may have been caused by the turbo being dropped.

It could have been if it were dropped from an extraordinary height and I mean 15+ feet. Even then it's more likely to break at the bearing housing register than it is at the turbine housing.

There is a reason they don't offer a TD06/6H variant TD06SL2 is as big as they can go. Any bigger and the housing becomes so thin it will melt, look at my link on the previous page that's just machining out for a TD06 turbine and it became paper thin and melted. There are better chinese housings out there that will allow larger turbine's but it would cut into their profit margins significantly and they wouldn't be able to sell them at dirt cheap.

Interesting how the one and only post by Michael @ FP in the whole thread is to put it down instead of giving good advise or ideas useful to the people trying these turbos out, i was wondering when was this gonna happen, BTW any turbo from any manufacturer it's gonna have failures, it's the customer service that matters most, which i Hear FP is prrety good at, in my own personal experience with the 25G i put over 8k miles at 30 psi and 520hp before upgrading to the billet wheel and overhauling the turbo, not because it needed it btw, just because i was installing the wheel. After selling the turbo it has already racked up 3.5k at 28 psi and 532hp, (video coming soon) , of course that was just my experience.

That is the first type of failure that I have seen like that with this turbo. They have great customer service and offer a 1 year warranty so your best bed would be to email them and see what they say.

Of course a big name is going to come in here to put them down. They are the competition. I am running the feed line from the head on this journal bearing turbo and have so for the past 3-5k miles without any bearing failures .

This turbo works perfectly fine for me and i'm making great power with the minimal mods that I have.

Nobody answered my question but at least this thread came back up... LOL So do i need more than a 1bar actuator spring in my actuator to boost more than 14.7psi?

ok, i'm an idiot

after more and more experiments my hands dropped. i do not know why
the turbine does not boost more then 1.8 bar.
wg works perfectly, spring real 2.0 bar, but we can't see boost
more then 1.8.

it seems that flapper not fully closed or very easy to open, maybe
some problem with 11.5hotside. improperly cast >>> big backpreassure.

Bruce promised to send me a new one, but lost...

I will send the housing with polish to get more smooth boost.
Our warehouse staff are making the custom polish service and will ship it
I'm tired of waiting for an answer and write letters to the void, then I started hearing exhaust leaks, results you see.

I had big hopes for this turbo, but...

Unfortunately, I spent a lot of time and effort into this turbo, for a total of about $1500: Turbo + shipping + installation + tuning (fuel) + removal and installation again. I probably would have been able to fp green and not know the problems. Now, I can just throw it in the trash.

Actually we try not to play the "we're better" game we tend to let our products and customers prove it.

The main reason I'm in here is because I'm an enthusiast and I hate seeing people getting scammed. They're selling you $200 Chinese built turbos that are built out of **** material without any qc and telling you they're quality units designed and built by a team of "engineers". Trust us we've been approached by these people trying to sell us product. We've taken the samples and had them tested and they are consistently extremely poor.

Go to their website and just start reading, you'll quickly notice that their over use of buzz words and bad english scream "WE'RE BLOWING SMOKE UP YOUR ***". It saddens me to see a community targeted by the fly by night leaches that will suck you dry and when the waters get too bloody they back away or change their name and go right back at it.

We've been here for 14 years doing the same thing we've always been doing. If our failure rate was as bad as the internet would leave you to believe do you think we'd still be in business? HELL NO!

So sorry I don't mean to tear them down but they are what they are, and the people that want to save a buck can and maybe they'll get a decent turbo and maybe not.

No.

The WGA spring pressure sets your lowest boost setting not your highest. However it will hinder you on higher boost since back pressure in the exhaust housing may blow the flapper arm open.

A general rule of thumb and will vary a lot given different turbos but spring pressure + 10 is usually your max PSI. Could be more, could be less, but it's a good start.

Thank you for the response. I'll try out a 1.5bar spring and see how it goes then.

LMAO , and that's not trying to put them down? We know where these turbos are made and where they come from, when i paid for this turbo i wasn't expecting the Rolls Royce of turbos, at some point you get what you pay for, don't even dare and treat us like naive, unssuspecting buyers that don't know what they're doing, Don't feel bad for us either, we're not getting scammed as you suggest, the way i see it, my $900 turbo has lasted me for well over a year at 30 psi and 520hp and i don't baby my car, i beat the crap out of it every chance i get, even if it only lasted me a year i would have gotten my money's worth out it, these turbos are a very good option for the price, i was sure as hell not gonna pay $3,000 for a stock replacement turbo no matter how good it is or how long the company has been in business for,just can't justify that much money for a stock replacement turbo, no turbo company ever including yours is 100% problem free 100% of the time, they all have failures or problems at some point, so even with FP they may get a good turbo or they may not, that's just the way it is with everybody.

That's exactly my point my friend, it can happen with any make turbo, just don't appreciate when people try to sell themselves or their product by putting someone else down instead of helping, which is the whole idea of this forum.

Here is the link to the video as promised, we tuned it like a month ago, this time around we couldn't run anything over 28 psi due to the external wastegate set up hooked up wrong, 532hp and 420tq on a built 2.0 and e85 Speed Density on stock ecu, not bad for a $900.00 turbo! what do you guys think it will put down at 42 psi?

Holy crap that is beautiful!! can we see the whole graph!? get the damn pdf. Finally a Dynojet dyno with beautiful numbers at only 28 psi! I'm excited for my build! I'm hoping to hit 550whp 30 psi e85/110 mix. I will be revving to 7.5k on my SS when built.
