HTA Green - the best IMHO
OK to answer a few questions :
(1) What turbos have I had on my car : stock 9, used BBK Full, and rebuilt / converted HTA Green. I have also driven a track car with a 35R variant. The HTA Full is awesome - power is always on hand. Frankly I know my setup is still not ideal for the turbo and I should get cams.
(2) Redline on my car - currently set to 79XX (basically 8k) , but I never really take it beyond 7500...
(3) Surge - Absolutely NO SURGE. I have tested the car in 6th gear, going up a hill, WOT from 2,000 rpms....Yes I do have the 84mm cover.
(4) Pump - I am happy to disable the Meth/Water injection and tell you what the HTA Green can do on 91. I am guessing that it will be somewhere around 75+ whp over the stock 9 turbo. That said, I personally believe the larger turbos really shine with more boost and better fuel than 91.
(5) Headstuds - still 100% stock...I don't believe there is any reason to put aftermarket studs in until I do the cams.
(6) DV - I am currently running a Forge unit, although I am considering other options.
(7) Clutch - ACT HD
(8) WGA - stock
Again, the team at FP are amazing. They are always there to help and answer questions, give recommendations on different setups, etc. If you have any questions, just call them...

There is no surge any where in the RPM range. I'm also running the stock bov crushed and it still operates like it was unmodified. I didnt crush it to the point where the nipple is totally bottomed out. Originally I crushed it about half way point from bottoming out to hold 25 psi with my stock turbo. I pressure pressure tested it as well thats why I didnt go any further. But with the HTA Green i didnt pressure test it yet but I did crush it a little more just a couple mm from the nipple touching the bottom base. Yes I know it probably still leaks at 30 psi but I need to get a clutch and cant afford to upgrade the bov right now. But I'm mentioning this just to let you know that even with current condition it doesnt surge or have flutter.
Full spool of 31 psi on my car with stock internals and conservative tune is exactly at 4k rpms in 3rd gear. As I go up in the gears (load increases), hitting full boost becomes even sooner. I'm running FP 25 psi wga and Hallman MBC RX Pro.

^^ NO ...do you know the hp formula 
??? 400 wtq @ 7500 RPM = ~570 whp....If you are looking for a 600 whp turbo, you should consider the FP Black or one of FP's 35R HTA variants...
