Where X amount of boost comes in doesn't matter. It matters where it makes 200wtq, then 300wtq, etc. A turbo kit at 20psi makes more power/torque than a 71hta at 20psi.
True point. I guess since all the turbos I've ever used run the same psi, I've been concerned with how quickly they get there. Plus I run smaller turbos, like these, so 20psi on this turbo would be a decent indication on how it spools compared to, say, the FP Green I used to have. But if this turbo flows completely different then yeah, the next thing I'd be looking at are torque numbers. I just didn't wanna type all of that in my last post. You know how lazy I get.
These turbos will produce in my opinion, if the mar-m wheel delivers as it should :
G25 550
93oct 400-420whp dynojet
e85 480-500whp dynojet
G25 660
93oct 460-480whp dynojet
e85 540-570whp dynojet
* as a side note the mar-m turbine wheel, shares enough blade aero design features with the p-trim wheel, let's just say they are a bit more refined in this new little turbine. Another plus,is the fact the mar-m alloy allows them to make the wheel of less mass without compromising rigidity, molecular strength and durability in comparison to the 718c inconel for example. Being a 9 blade helps to reduce backpressure at high rpm/speed.

Reason: typo
In my opinion it does, and just because you are a moronic ignorant, does not make my opinion obsolete nor false,p-trim is still in use by garrett (revised/re-designed version) in its new gtw series turbos i.e, now go address someone else with your horse****.

Hey mate, I'm sorry, that was probably a little rude on my part. I just found it funny that you would suggest that new tech turbines share aero with old turds like that. Yes they're the same net shape, but that's where the similarities end. Also if you think Garrett would go back and redesign a dead turbine, you're confused. They've had the GT turbines out for like 25+years and never changed them. The GTW turbos are budget turbos because they use the old T-series turbine wheels.

No you are wrong, the one who is confused and not aware of the subject matter of aerodynamics is you. I have the knowledge and the ability to design a compressor and turbine wheel on a CFD, do you? The shape as you call it, is actually the aero design of a wheel, a design which bares certain same characteristics as the G series as I previously said. Garrett has indeed redesigned the p-trim turbine wheel, and there is also the old version of it still around. They have based the new G series turbine wheel on the new version of the p-trim wheel , which already existed but was widely introduced through their GTW line of turbos. For example the garrett TO4Z turbo uses the same CHRA and housings as the GTW series but has in use the old type of the p-trim wheel along with a cast version and older type aero compressor wheel. The reason the GTW is cheaper than the gtx series is not that they are inferior turbos to the GTX series i.e, real world evidence has proved this, but because their CHRA and housings are based on a bulkier version, they use the older design turbine wheel, EXCEPT from the p-trim wheel.They share the same compressor wheel design as the gtx series, the gtx series also uses T-series turbine wheel design, i.e the gtx3582r gen 1. In other words, the gt35r, gtx35r and gtx35r 2, share the same design turbine wheel. They contined using the same design turbine wheel, but improved the compressor wheel on the gtx gen 1 and slightly further improved it on gen 2. The only redesigned turbine wheel by garrett is the newer version of their p-trim which was released around 10 years ago on their T-series turbos and used to replace the older version of the wheel in most applications,and of course the new version was used in their GTW line of turbos. And now they have released their newest G series turbine. There is also marketing to take into consideration here.
Hate to break it to you mate, but the picture in that first link is a stock photo of the g-series wheel.
I'm not sure where you're getting your info from, but it makes no sense for Garrett to redesign their turbine wheel and put it in a cut-rate turbo. Their release of the GTX3584rs and g-series has been what the world has been waiting for after soooooooo many years of them recycling their GT turbines with new compressor wheels.
Btw GT turbines are not T-series turbines. The Stage 3, Stage 5, and P-trim are all dinosaurs. Those are the turbines the GTW line uses as it goes up in compressor size respectively. The reason they're not total flops is that the new, highly efficient compressors mean the turbine has to do much less work than when they were in old T3/T4 hybrids.

waiting for results before I pull the trigger on my Supra. Can't WAIT to see how it'll do.
