There is seldom a free lunch. The taller wheel on the BW ETT 475 chargers give you better drivibility, and a wider map, but lose a bit up top. On a virtually identical Garrett 75mm with the "normal" wheel, the Garrett is making about 20rwhp more up top, and is just over 0.1 seconds and 1.5 mph faster.
Is this the same with a BMW? I dunno. I do like driving the BW ETT better.
BTW, the basic blade designs used today were developed by NACA (NASA) during WWII.

I think this whole batmowheel is just a sales gimmick! I think the fact that the wheel is lighter probably has more to do with the better spool up than the goofy curved inducer. Enertia has a lot more to do with spoolup than this blade design IMO. The old billets from bullseye were just a direct copy of the cast wheels I.e. Heavy! This new BMW wheel looks to be carved down more around the hub.
That BatMo looks way different!
Is that thing headed to western PA by any chance?
It sure is. I'll be testing the 75mm at the track in a few weeks if I can make it there.
Just got a Turbo from engineered diesel with a billet wheel... are they made to there specs u think?
I just emailed Bullseye last night asking about what I could do to my S475. I was hoping to just upgrade the wheel and not replace the whole charger. There site says that they have the new BMW in stock, I took it like you could get just the wheel. I guess I will see when they respond. What does it typically run for a billet wheel in an S475????
I talked with Bill Devine via email and the billet wheel and race cover is around 800.00. He said the BMW and cover are only offered on a new turbo.
