Standard GT3582R with a .82 T3 turbine housing, by the way. It's mine and it's already been repaired.
Right, because spool is all that matters and total airflow production has nothing to do with anything at all. If what you're stating were true every aftermarket turbo made for our cars would have a TD05H turbine.
What you're forgetting is that any time a wastegate is open, a good portion of exhaust flow is going to exit through the wastegate. On a setup running low boost, someone may benefit from a larger compressor if they don't mind the lag because the biggest portion of the exhaust energy is wastegated.
Now let's turn up the boost to 38psi and channel all of that additional exhaust energy directly at the small turbine wheel. Exhaust backpressure builds, EGT's go up, the car gets harder to tune, and you're making less power while doing more damage to the turbo by running that magical wheel combination.
Hell I have a customer right now who specified a .63 Garrett housing on his 7-blade HX35 and it turned out to be a complete dud, only gaining a few additional HP over a T04E60 Garrett that it replaced. The excessive turbine restriction giveaway is that the same wastegate setup which controlled boost fine on his 60-trim suddenly wouldn't stay closed with the HX35. The turbine backpressure had increased so significantly that the wastegate had a hard time staying shut as the RPM's climb.
...but what the hell do I know. I just f*ck around on the internet all day.
Didn't come from my car, I bought it that way as a rebuildable core.
Then why insist on starting shit in this thread and just about every other thread you've posted in recently?
...completely contradictory of your HX35/40 statement.
It was built to fit a specific application requested by the customer with zero knowledge of how it would perform. I assumed it would be fine judging from the results I've had with my HY35 users, but it wasn't. Live and learn....you can't win the lottery if you don't play.So since you know all about this turbo stuff why did you rip off your customer and had him waste his money on something that you knew ahead of time will be a waste

That works in some cases, but not all. For example I wouldn't recommend such a setup for a 2.4 guy looking to run high boost....the 70/60 HX35 turbine still won't be able to keep up with the compressor unless you go to a 14cm or 16cm housing, at which point you may as well use the HX40 turbine and a single-scroll T3 .70 housing which Dave and I have already proven to 151mph trap speeds. I actually feel there's room to grow with that setup as well.
Absolutely true, and I feel the same. This is likely why FP stretched the exducer of their HTA3586 out to 86mm and saw huge gains.
Most everything I've posted here has been proven as well. We know the .55 Bullseye housing is already restrictive enough using the HX35 turbine, so putting a HX40 compressor on such a turbo would be a horrible idea....but I agree it's a completely different situation with the factory 12cm housing to a certain point.
its a wastegate that I bought on eBay for a different project but didn't end up using. It's actually a nice piece, well made. I replaced the diaphragm in it with tial one since that's the only thing that I questioned on it. So far no problems with the wastegate. The thing that I didn't think about when I put this wastegate on is that it had a big valve which creates allot of surfaced area for the exhaust pressure to push against. It's about 4 square inches so at 25psi of exhaust pressure there is 100 pounds pushing on that valve. I didn't realization all this till this whole wheel upgrade even though it did fix my boost drop at 30-31 psi which I talked about in the begging of this post, but I still got the boost drop if I tried to run more boost. I didn't think that 2 springs in the wastegate wouldn't be enough. So the other day I put a 3rd spring in my wastegate and tested it with my home made tool. Wastegate started to open at 32 psi. I put it on the car and turned my mbc way down just to see what's the lowest boost it will run. Between the boost and exhaust pressure it ended up holding a steady 29 psi. Cranked up my boost controller a bit and 35-36 psi seems to be a walk in the park 
so far I pushed that wheel to 39 psi and it hasn't come apart, it felt pretty heave and the blades seem to be heavy duty and no all thin and flimsy. I've been checking that wheel for any blade flex and it still looks like when I got it. Maybe not all China stuff is garbage though I will agree most of it is. As long as it holds up I think the design is there, I did see 3-4 lb/min more with that wheel.
Not trying to start a debate...but I find that seriously hard to believe at the price the wheels are being offered. Add to that all the emails in terribly broken english that I received when I was having issues with that place a year or so ago.
and just because you make good product don't mean you have to overprice it like some of the companies I know, not going to mention any names but $400 dollars for a 60mm wheel or $2000+ for a 54mm turbo might ring the bell
