The 20g compressor I used off eBay had straight fins. It had no surge issues, unlike my mhi 20g.

Very interesting and good to know!

Feel like bringing this one back...any more people used or found any more info or numbers on these? If the 15% gain claim is true, that would turn a 42 lb/min E316G into a 48.3 lb/min turbo, which is basically the same as a TD05H 20G. 16G spool with 20G flow would make a killer street/course car and an "easy" 350 whp pump gas 16G setup...in theory anyway.

I bought one of these wheels recently...still deciding what turbine to pair it up with to get the maximum amount of spool versus airflow potential (clipped TD05H, TD06SL2, TD06, or TD06H).

Why not one of kamak's 9 blades?

I don't like using aftermarket turbine wheels with my expensive billet compressor wheel, which is why my least-favorite choice is the TD06SL2.

Aren't Kamak's turbine wheels also billet though making the rotating mass even lighter?

There is no billet inconel. They're cast.

Must've misunderstood their description. They make it seem like their turbine squeezes every bit of efficiency out of that billet wheel though!

How do people feel about the newer 10 blade "high flow" design billet wheels vs the ones that keep the dual 6 blade design?

Why not pair it with something you already have data for so we can see just how they perform vs a known quantity?

Scientific method FTW.

Because I don't want to build and sell a dud, nor am I well-funded enough to buy four of these wheels and put one on each turbine. Just trying to do some research and come to a conclusion on my own, and I'd prefer to use a MHI turbine instead of risking breakage from using an aftermarket turbine with little results.

Justin please let us know how it turns out with whatever turbine wheel you decide. Get some logs if able -=D

I would just like to know if the 10 blade version is truly capable of flowing even more air like they claim. I know when it comes to turbine wheels the ones with fewer blades usually flow better, especially up top. (like the holset turbos)

Well we have a new vendor. 3 or 4 styles of billet 20g wheel from about $130 to $180 shipped. kawasakiturbosystem | eBay

Any body have a guess as to the advantages of the different styles?

11 blade extended

Duel 7 blade

Duel 6 blade extended

And not sure how the 4th one is different.

Those don't look right... That 11 blade looks like a 14b.

Maybe to much of a wide angle lens? The blades look really tall.

From a 20g thread

Less air flow out of a billet extended tip? If that's the case why has every company this year switched to the 11 blade design?

I would expect 3-5 more lbs/min with that billet wheel. If you want maximum power, that compressor wheel with a td06h/4 is the way to go.

Wow, they offer several variations of the 20G wheel.

From what I understand, the wheel with more blades will be more efficient at lower boost levels, and the one with fewer (but larger/more surface area on the blades) will flow more at higher boost levels.

If it were me, I'd go with the one with fewer blades.

Awesome prices, too, as long as the wheels work and don't explode on us.

The new Garrett gtx wheels have 11 equal height blades, and perform better at high boost than the older 6/6 gt wheels.

They flow more because of the surface area is greater than the 6/6. They spool faster because they are lighter.

Look at the batmowheel, its not a 11 blade design.. It's a old school 6/6 it uses more surface area to increase the output.

Extreme tuners is working on a extremely thin magnesium wheel, so i'm sure we will see more surface area in the near future.

Question is can any of those billet wheels run in a TD05 compressor housing without surging horribly at part throttle in higher gears? I love how fast the 20g spools in the smaller housing (significantly faster than an 18g in an 06 housing), but I had to change out the compressor because of part throttle surge in 4th gear. I was hoping for a 5/5 offering similar to what FP used in the green on the evo. I'd love to find a compressor that was as good as the old 20g in the small housing, but doesn't surge.. at least until I swap in the V6.

And that's surging on a TD06-8cm turbine.

Man if you're surging with a td06-h turbine I don't know what to tell you except maybe try a ported (anti-surge) compressor housing. I use one on my billet 20g but also use a td06sl2 turbine wheel for good comprimise in spool time and top-end power. Here's mine:

Where are you guys getting the 8cm turbines from?

Super Boobs... I mean Subaru's. Kinugawa makes new housings also. You can get 8cm housings in both TD05H and TD06, most are flanged for a T3.

So you are running a subaru td06h hotside? What manifold are you using? Are you still using an interal flapper? seems to me like a lot of custom work to make it happen. Custom manifold, o2 housing, downpipe. Maybe compressor cover modification.

BTW, FP sells a 8cm hotside 295 they priced it at. there was also talk of a group buy a couple weeks back on this subject. I would contact FP and see when they are going to do it.

syty's came with a t3 8cm housing thats td06. There is a 8cm housings(mitsu flange) not sure where they came from. Hahn made 10cm t3 td05h housings

8cm mitsu housings, were a factory upgrade for the 14b I believe.

The t3 td05h housing came on the syclone 20g. it has a 3 bolt outlet flange with an internal wastegate.
