Thanks!
We put the wheels on the car and did not have the sexy we thought it would. Once we put the suspension on, it changed everything.
The wheels IMO are amazing. I recommend them highly.
Also, these wheels are prone to leak air. So what we do for our clients is hit them with a bead of silicone to seal the halves. No more leaks!

M-
You would not go near the VTG's or 9ff?

Here is his response:
Here is a breakdown of how the various turbo compressor maps compare:
K24: ~32 lb/min @ 60% efficiency
Stock VTG: ~34lb/min @ 60% efficiency
Garrett GT28R: ~34lb/min @ 60% efficiency
Garrett GT28RS: ~37lb/min @ 60% efficiency
AWE Tuning VTG: ~40lb/min @ 60% efficiency
A general rule for calculating a turbo's HP capability at 60% efficiency is: 9.5 multiplied by flow.
Since this is a twin turbo car, multiply that by 2, resulting in:
K24 : 32 x 9.5 x 2 = 608hp
Stock VTG: 34 x 9.5 x 2 = 646hp
Garrett GT28R: 34 x 9.5 x 2 = 646hp
Garrett GT28RS : 37 x 9.5 x 2 = 703hp
AWE Tuning VTG: 40 x 9.5 x 2 = 760hp
Granted, this is a basic formula which does not take into account the turbine design, intercooling, relative efficiency of the engine, etc., but you can see that the numbers are pretty representative of reality with the Garrett's and K24s. And we're just shooting for 700hp, which is well on the conservative side of what our turbos theoretically can do.
We have not touched the turbine side in order to maximize spool up characteristics. We believe a balance of torque and hp is really what the market wants. Big HP numbers with lots of lag and an anemic low end does not make for a very enjoyable driving experience.

Please let me know if you have any further questions.

Why do you dimantle them? We just seal the halves at the gasket.

FYI, BBS says that if the wheel is used, the hardware should all be replaced if you are removing the center. If the wheel is new, the hardware can be resued. Just be careful when bolting it together.
Torque spec is 145 in/lbs.
