A look into what's involved with designing a compressor wheel and some GTX detail info:

That is really interesting. Thanks for posting.

No, why the heck would you think that?

I should be testing the GTX3582 vs. a standard 3582 in Shawna's car after the new year. Hopefully it does everything they say it does.

Uh, they look about as similar as a STI hatch and a Miata. Yes, they're both machined out of aluminum, but that's about the only thing that's the same about them.

I take it you don't know much about the history of Garrett (now offically Honeywell Turbo Technologies), so here's a link:

And some really cool info about the latest stuff:

So funny how a short while ago garrett was dismissing billet wheel technology.....

honestly.. i dont care.

but i had never seen a billet wheel on a turbo before FP and the hta turbos. those turbos have proven to be monsters and now im starting to see most new turbos come out with billet wheels.

i really dont know much anyways, my evo was the first turbo car i owned. i do know that in the 5 years of owning it, i was constantly looking for turbo upgrades and non of them had billet wheels. then fp came with their hta turbos and bam, now they are popping up everywhere.

im sure garrett has perfected the billet wheel.
compare fp hta35 to garretts new? 35r

billet wheel technology basically allows them to keep their followers who have been skipping camp going to precision and Fp types of turbo's due to the billet design being more efficient

Even more funny is that Garrett built the TR30r Billet wheel turbo for WRC and Peugeot Le mans car as far back as 2000.

There's nothing 'technology' about 'billet'. Billet is simply a material form. The improvements in the aerodynamics are what improved the performance relative to the older designs.

Garrett chose to fully machine these due to low volume and time to market. They chose to machine them from forged billet to increase strength and therefore reliability.

OEs stick to speed limits for turbos, people in aftermarket do not; i.e. people overspin the hell out of turbos so might as well make the compressor as strong as possible short of going with titanium.
