First pricing I've see listed. The one I would have been interested in which is the 8374 w/ divided T4 and internal WG is around $3000 (part number 179357).
So yup, I'll just be sticking with the 84-75 I have now, im not ballin like that haha
Some info from Geoff @ Full Race that I thought was useful.
If you go bigger on the compressor that is the same thing as going smaller on the turbine. I put up a bunch of posts explaining the U/C ratio of Compressor OD / Turbine Wheel OD in that big road racing turbo thread... basically divide the compressor OD by the turbine OD - an optimal match will be in the neighborhood of 1.09-1.18 whereas a mismatch turbo will be 1.18+... Also keep in mind that a small a/r will have low turbine efficiency at low flow rates, and higher turbine efficiency at higher flow rates. Conversely the large a/r will have high turbine efficiency at low flow rates and lower at high flow rates...
6blade compressor wheel -- ideal match ratio of ~1.14-1.24
7blade compressor wheel -- ideal match ratio of ~1.09-1.18

Boost was off on the 35.25 run I maxed the 50psi Absolute sensor which maxes at 35 when we did another pull it was 38.X psi and the sensor is off by 1psi reading higher so we got it to 41 psi.
The 608 and 553 are 3rd gear pulls and the 616 is a 4th gear pull.
Figured I'd share some results I found from someone running my same 61mm turbo (BW S300sx 84-75) on a Supra with a .88AR T4 open exhaust housing and 264/264 cams. Thought they were some pretty good numbers for a 61mm.
My plan for spring is to go back to an internally gated setup, 90% sure I will be rocking the 7670 .92a/r BW EFR. I have spoken to a lot of people and it looks like its what I am looking for in terms of down low power and powerband, should have peak torque around 4k rpms.
Most who have tried this one on Evos say its a stock turbo on steroids feel, can't wait to try it out.
I have been very skeptical of BW turbos for a while, ever since they released the EFR's but almost every turbo in the top 5 for world time attack runs an EFR now. I have tried everything else, mind as well try this right?
Here is an Evo X comparison (2.2L motor) of the 7670 EFR vs the 9180 EFR
