You might be able to pull something like that off with a quick spool valve..

Tried that. Doens't work. 12cm turbine is way too small.
So, is there any possibility of a TS T3 or T4 housing that is small enough to go spool around 2500-3200 for an HX35 and still pull through redline around 7500? That would be the best setup ever with a buttload of torque and horsepower.

get a 12cm T3 HX35 housing machined for your setup and you would spool up faster and it wouldn't hurt your top end.
These stock housing were designed for large displacement slow moving diesel engines thats why they are so large

Exactly.
If that were the case who would want/need a different street turbo if you could get a 40 to spool at 3200 and pull 70lb/min?
i love my .63 single t3 turbine on hx35 turbine and 8 blade hx40 comp... broke trans at 31 psi and 522hp, and previousely best was 482@ 27-28psi, gpesny seem to choke to me, was roasting all 4 tires in first and 2nd last night taking a friend for a ride

You're confused. The 3200 spool remark was about an HX35.
so you had one machined for a HX40 and it choked up top?
no, the quick spool valve. I have done that on a 12cm HX35 housing.

There's some things that aren't around because they are as they sound "too good to be true"
Anyway, best bet for you would be the VGT HVE351 or whatever it's called
Hell, my turbo spools FAST, the gate can be open before 4800RPM at 28psi in a gear where it can load enough to boost before it passes the RPM (third at part throttle sometimes i make insane boost levels at 3600)
Not to mention that with that much of an early spool you're just gonna break parts with too early and too high of a torque onset, better go auto tranny if you get soimething that could perform like that. (you can introduce nitrouse after 2500 RPm, before that it's known to bend rods, so that may be a good answer for you.. I love the balance i have with the T3 .63 a/r single scroll setup, but i'd still love to hear about the .84 TS t4 housing i machined for the guy in florida and how it's going, the gt35r housing that wasw a bolt on mitsu flange can be read about in the california local area thread about a lot of holsets for sale by boostedtalon... he's getting even earlier spool than i do....
My only thing i ask anymore is "when are people gonna be happy enough to stop asking for more" use to be a 600+ capable turbo wouldn't be spooled til about 5k RPM< now we have the holsets that cfan spool before 4k and now people want 600+ HP and spool like a T25....

a T4 .84 TS setup, I forget his spool numbers but they are in that thread

i dont think a .70 would make too much difference for you in this case
I am dropping from 35 psi to 30 psi in 3rd gear by 7500 rpms. I am still maintaining 53-54 lb/min, but I would like my boost to stay constant and maybe pick up a couple lb/min. If that is achievable then it would probably be worth the effort to go from .63 to .70. I can sell my existing housing and recoup a good bit of my money on the upgrade.
Have you tried putting a boost line on the top of the wastegate?
1. limit the travel of the WG, so initiate a "boost creep" situation. Kinda works, but not all the well.
2. Use a bsc solenoid to limit the signal to the wga. I did that and tuned my duty cycle curve to my calculations and drive pressure, and it was almost perfect the first try!
Not sure on that one, although I better have something up my sleeve when Dave maxes out the Bullseye housing....and I'm sure that's going to happen sooner rather than later.
I've given thought to a .82 T3 housing, but judging by how the .70 Bullseye housing has performed thus far it makes me wonder if it's really a .70 a/r or not. I'd sure hate to do a ton of machining on a .82 housing just to have it perform worse.
The driving force behind the .82 option for me has been the success of that particular housing on the FP 3794.
