Crazy looking billet wheel

[Bakn2Gns]

Has anyone had any experience running these wheels? The theory is
they're shaped like a jet or gas turbine engine blade. It has more surface area so it moves more air. A Turbine engine has multiple compression stages. They also have to keep temps
under control. They laser cut microscopic tear drop shapes in the blades for cooling. So I have no idea why they're shaped for more surface area.
Has anyone tested these? Hopefully
Bison or Patric can give some insight into this design.

Last pic it a turbine

If anything it looks like a work of art!

That's the wheel Turbonetics uses right? It does look cool; I'm interested if it makes any difference though. I'd expect any difference to be only when running the wheel all out.

That looks like a higher pressure wheel. These wheels are becoming more common as the racing market grows. "Batmowheels"

Bullseye Batmowheel…. supposed to be a beast! i think they call it Extended Tip Technology, There was a guy on this board that was going to experiment.

This one is an 88 if I remember right.

It's cool to see what people are doing now. With a 5 axis mill you can rapid prototype wheels for R&D without having to cast 100-1000 at a time. Look at how much machined wheels have changed in such a short time.
I want to see bore-less wheels made
Like the wheels now. Same wheels just get rid of the hole and the nut.

I work at a turbine shop And have seen these. I'm a maintenance tech so I "only" keep the machine running and accurate but when I asked engineering they explained that it aids in reducing bypass losses and improves the overall efficient of the unit especially in the upper pressure ranges ie max power. Given that I could see where they may help.

This would be nice in 64mm..

They have been available for a long time

Are these the wheels that come on the CEA turbos that PTE supplies?

These particular wheels are made by Bullseye turbo.

I've seen quite a few imports and diesels running these wheels.

At what boost pressures are they supposed to be more efficient? 25 /30/35 + ?

These wheels perform very well at 30+psi. Like most of the Borg based stuff, they can b taken to 4.5+ PR.

DAMN! That's a crazy pressure ratio, but I suppose that's what it takes. I thought 3:1 was normal and about all most did. Thanks.

Here is a good example. This is a Borg 82mm MFS extended tip wheel.

If you're looking to make 1400hp you aren't doing it at 3:1 on these small engines. It takes a lot of mass flow and the only way that's happening is boost and rpm.

That's a great example of a compressor that will work very well on a v6 looking to make 1100-1200hp
