Borg s488 anyone?

Maybe to initial spoolup but max boost and flow comes from turbine torque.

Weight plays a role in max boost pressure, less mass allows a higher shaft speed with the same turbine flow, this is no secret.

Shhhh

but how do you lighten it ? Less blades, lower boost but more flow. Lower trim = higher boost, higher weight. Thinner blades, lower max rpm, lower max boost.

Not necessarily. Subtracting a blade and lightening the wheel can increase rotor speed, thus exit air velocity to the point where it can support higher pressure ratio then before. There are other ways of lightening the wheel without taking a blade as well.

Milled forgings are considerably stronger than cast, they are capable of higher rotor speeds without bursting.

What about the s595? Other than the fact that it is hideous.

Why not the 88mm S500sx.

Price..trying to keep things on the cheaper side (i know, not ideal).

I did make a purchase though this morning.

I will post some pics and specs when it shows up in probably 2 weeks.
