Turbochargers for ballers

Cool... they rebuilding ball bearing turbos... and hiflowing them at the same time.

*snicker*

Gotta admit, they have balls for suggesting that their claim to fame is the worlds fastest oem chassis RX3... yeah.. that's.. um.. great.. Nice job guys.




Technically, the silica nitride does have the properties that they mention(high heat tolerance, light weight), but it would work as a bearing, if and only if, the race was of a similar material.. if it wasn't as hard as the silica nitride.... hot silica nitride would cut right through it..

No uncoated metal would stand up to abrasion by silica nitride bearings at 100,000 rpm...
The rings on the metal would have to be coated with something, probably alumina oxide.. given their love of aluminum, and just because that's about all that would stand up to silica nitride in those conditions. But they don't mention that.. hmm....

Interestingly.. they aren't using bearing cages-- I wonder how the bearings stay in place?




Other items of note - they are using aluminum as the center cartridge section.. an interesting choice.. the cooling had better be top notch otherwise that aluminum will melt at turbo temperatures..

Point of note:
Melting point of Iron: 1500 C/2800 F
Melting point of Aluminum: 660 C / 1200 F
Typical Temperature of Exhaust Gases: 900 F -- 1800 F

We've all seen the cast iron turbo manifold glow red.. iron starts to glow red..

point of reference, for iron:
C__ F__ Color
400 752 Red heat, visible in the dark
474 885 Red heat, visible in the twilight
525 975 Red heat, visible in the daylight
581 1077 Red heat, visible in the sunlight
700 1292 Dark red
800 1472 Dull cherry-red
900 1652 Cherry-red
1000 1832 Bright cherry-red
1100 2012 Orange-red

That's a lot of abuse for a aluminum center section... it'd work with sufficent cooling.. but that's real chance to take.

And aluminum will transfer heat much better than iron, so more heat will leak from the exhaust side to the compressor side.. ie. more heat into the intake charge... unless they have added some phenolic spacers in the system.. which they could have..

And inconel is good stuff.

I guess I'm saying that most of what they are saying sounds legit...
Of course, they still don't define "hiflowing" but in this case, it seems that they suggest that they are completely removing the turbine and compressor wheels and *completely* replacing them with a differently designed turbine and compressor wheels machined out of inconel.. A different designed, could constitute "hi-flowing" a turbo.. if you are using turbo to refer to the entire package. Using a redesigned turbine and compressor with a new center section which has significantly better bearings... even if it is using the same housings.. well.. that could change the whole compressor map, which could increase the flow, or at least change the efficency of the entire turbo.


Yeah, it seems fishy. Lots of good stuff.. but.. still there be mumbo-jumbo if you look deep enough.


note - I am not a metallurgist, but I have worked in a materials science lab doing testing on silica nitride, alumina oxides, and some other fun ceramics.

lol this pic.... the site would be on the side of the van. from the above amazingly information filled post, id add maybe the hi-flow comes from their design, the bearings, changed parts, etc.

Every other turbo manufacturer distributes some form of an efficiency/pressure/rpm/compressor map.

You can't really do a good job of picking a turbo without a compressor map.

(okay, they suck.. page is being updated.. it's just a place holder.. but it isn't hard to find turbonetics compressor maps)


A/R is nice, Inducer/Exducer diameters are nice, HP rating is nice, but they don't post things like flow rating at a particular pressure ratio, or compressor maps, or nothing.

They are giving the appearance of legitimacy, with out backing it up. If they are an actual aerospace product provider, they would have to provide details specifications and efficency diagrams... so either their web page sucks horribly.. or... you can draw your own conclusions about any group of people who doesn't tell the whole truth.

hahaha you guys are all funny!

They have their target market covered. Re-read the page. They aim their turbos at skyline owners. Not sure how many of them you guys have over in the US, but here in Australia, they're everywhere. All performance shops are 'specialists'. Majority of Skyline owners are happy to throw money at their cars, so to me it looks like it's about targeting your market ....

They've been around for a while, with products displayed at shows, etc. Basically, they build turbos to your requirements. I'm also sure that they are out reach for your average punter wanting to make 200hp by fitting a T3 to an F2....... :lol::lol:

Don't take this personally, but instead of having a sook about not being able to find maps for a turbo that you're never going to buy, stick to local products. The prices that you guys can get good quality turbos for versus what they go for over here is crazy. So why would you even look abroad??

The infiltration of China turbos? pah, if you can't tell the difference between that and a garret for example, then you shouldn't be playing with them
