HKS GTII... need info please!
All, can someone tell me why there is virtually no info on this turbo? I know it spools well, just want to know what it's maximum capabilities are in terms of power (on E85 & full boost). Is this still that new that nobody has pushed it yet? I hear the 8&9 version is totally different, so I'm not really interested in that.
Please post up a link if you know of one that's been aggressively tuned... like 30psi+. Thanks!

You are looking to kill your stock motor aren't you 
I have seen a few dynos, basically 400whp at like 27psi or so.
i am guessing with E85 and 30-32 psi with E85 timing you would be around 450whp tops with close to that in torque as well. It spools fast. But it dies up top like a stock turbo.

Haha, maybe... but do you really think a GTII maxxed out would give it more stress than it currently has with a Red maxxed out? Maybe because it will spend a lot more time in boost?
On a stock block? I know HKS's dyno was a built motor.
That's close to what I'm making right now, so if I could do that and have awesome spool it could be a win/win, and also be in the mid-high 11s (also where I am now, coincidently).
Technically, I also still have a long ratio trans at Shep. The smaller snail may like that better than the current Red or other big turbo would.
I'm also less into drag racing now, and more into track days, ice racing and 'spirited' street driving. Not so sure a huge turbo makes sense anymore, and if it does, then I will certainly go T3.

Here is the thread i was thinking of:

Yes, it will put more stress on the motor than your red if you run the same psi...I am not sure what psi you are pushing your red at now though. But since it spools faster it will/should make more torque and therefore more rod bending/snapping force.
The smaller the turbo the easier it will be to drive. So you should have no problems reaching 11's on the HKS one I would think.
The red is a low 11 capable turbo. 10's with the perfect drag setup.

Yeah, I've seen that thread. I'm at 33psi now. It's not the best drag racer either... 11.8 @121 under perfect conditions was my best. 12.0s are more typical. That may be just me though. If I could run 11s and have great spool, that would be sweet.
Don't really want to lose my nice top end, but the low end is annoying me. The Red is like a middle child. Big brother T3s get all the attention for big HP, and smaller stock frames are more competitive for autocross, etc., and realistically are just as quick on the street, with better response. When will we get a Porsche 911 like variable displacement turbo?? I think I'd have better chance of buying two Evos right now!

Look into the new EFR turbo's then, the borg warner ones.
Full Race will be coming out with a t3 kit for them soon, so look at them for great response and top end. They are supposed to be really good, not sure if I believe it yet, but it looks promising.

They aren't fully released yet and there are no turbo kits that utilize them yet. i think you can buy some of the turbos now that and make your own kit.
It looks like they are vband, so maybe the AMS kit would work with them, maybe.

Interesting, maybe I'll throw the stock turbo back up as a possibility until I decide what to do. 400whp/400ftlbs on a Mustang dyno would be beautiful. Not sure how realistic that is though. I'm assuming I have all the proper supporting mods .

I read somewhere that the GTII turbo gives the ability to hold boost during the shift. Could someone tell me exactly how that works, and if this would work on a different turbo?

It holds boost better between shifts because its a ball bearing turbo.
Journal bearing turbos, like the stock turbo and FP turbos will slow down from speed faster like in between shifts.
The ball bearing turbos slow down much slower and therefore hold boost better in between shifts.
