This is called the BatMoWheel by Bullseye Power:

I don't get it. Looks like a nice turbo, but what's special?

theres a extra little kink in the fan blades compared to a normal one i guesss. dont know what that does to flow tho :/

Did either of you bother to read the thread???

"Bullseye Power - Batmowheel

Bullseye Power just introduced it's new wheel design, the Batmowheel. The idea is that the blade design should have more surface area than the straight blade version. For example, the 66mm compressor wheel would have the same surface area as a 71mm. "

"For comparison, GE has been using the same design wheel in their jet engines and continues to do so with their GEnx engines.

Skip to 0:49 to hear them talk about the blade design."

The little fins look like it could possibly help bring air into the compressor? Really doesn't look at that aerodynamic to me.

and here I though it would have a bat symbol on it.

I was at that shop when it was installed on the boostlab supra, Advanced Race Technology here in sarasota. Pretty cool looking thing.

Sounds like a marketing gimmick to me since they really tell you nothing technical.
Fan sections in your average hi-bypass passenger airliner engine turn at around 2500-3000rpm. I'm sure the aero principles translate directly to a turbocharger spinning at 130,000 rpm. It's not that big of a difference.

I'm not impressed either.

Needs more compressor map comparisons.

I guess we'd have to see graphs of 2 identical turbos with different blades for proof.

It sounds like it makes sense... but lots of things can be made to sound good

Looks like similar sort of fin design...

Look fellas it's not revolutionary but overall the design can flow more than a standard wheel without the comprimised spool of a larger mm regular sized wheel. 5-10% is not that much but it is still more flow.

Seriously, this is totally irrelevant to the MT.net community. Few people here are maxing out their turbos. ALSO These turbos won't even come in T3 frame so just forget about ever running one on your miata.

I did look at this **** last night before I bought my T4 66mm standard wheel borg turbo. I didn't get a batmowheel because of a) cost-- I paid $700 for my turbo and this **** would have cost over $1400 and b) Although I would like a lighter billet wheel compressor, my plan is to spray water in it so I want something that's cheap to replace. I'm hoping pre-compressor WI will do much more than a billet wheel when it comes to spool.

Yes even the standard non billet or batmowheel borg ***** all over the face of garrett. Many people have swapped out their garrets for equivalent borgs and whupped ***

Where are you reading this? I combed the website and found no "data".

I'd love to know specifically how the wavy compressor wheel works better than a straight or curved wheel. The quip about "increased surface area" doesn't add up. How come airplane propellers aren't designed with a wave? There are curved blades on aircraft, but no waves. I'm just saying that if there was some solid engineering data behind it, they should be willing to at least explain it to the consumer. Increasing the surface area of the leading edge of the blade does not directly translate into more air being compressed.

I'm calling bullshit without a hard technical explanation.

For once I agree with you. Seems to me to be a way to do something different with their fancy 5 axis cnc. Just doing a billet wheel isn't special enough anymore.
