I need to compile some info off of you turbo guys. Basically what I'm trying to find out is what exhaust a/r housing you're using if you have a T3 hot side, and roughly where you're spooling at. VG30E, VE30DE, and VQ30DE guys only just to keep the numbers relatively close.

Basically this is the info I'm looking for:
T3 turbine a/r
Ball bearing or journal bearing
RPM in which turbo is at full spool
Engine type


Thanks in advance!

 

Dont forget to include what type of setup you have.. whether it be a Reverse Y-pipe, or custom or anything else.. That can Greatly Effect spool time.

 

VQ30
T3/T04S, non ball bearing
.81AR hot side
Full boost at approximately 3500 rpm. Starts boosting below 3000.
Setup is custom, but turbo feed pipe is pretty much like the PFI setup.

 

What is the HP goal? What boost level do you think you need to get their?

 

What kind of turbo would I need to approximately have it start boosting at 3000 until maybe 5500-6000 or...?

 

I'm not so much trying to find a good turbo as I am just compiling data. I think for my VG30E the T04E 50 trim fits very well. Should support upwards of nearly 480 hp at around 24 psi or so.

I'm just basically wanting to see what everyone is running and the spool times they're seeing. I have a couple ideas I want to mess around with in an attempt to speed up spooling while keeping the top end.

 

Turbonetics T66 .84AR exhaust
starts building boost at 2500rpm
full boost depends on the psi I am shooting for IIRC
13psi at 4200
18psi at 4800
20psi at 5000

This is on a VQ35 with 9.4:1 CR

 

i am also curious to know what would be the best size turbo for a vq30 to have boost at 3 till redline at 67... was thinking bout a t3//t04e with a reverse y.

 

VQ30DE
forward Y pipe
t3/t4 60trim .63ar non-bb
in 2nd gear
2500 rpm builds boost
3800 full boost 9.5psi
314hp
343tq

 

omg i think thatsexactly what i want cept i want the ball bearing for a more linear pull, out of curiousity how much did u pay for yours? also was it new or used?

 

i had it for sale for $350 but my boy picked it up. i bought it new for $600-700 ish

 

damn **** , would you happen to have the ability to get yor hands on another one?

 

In which gear are you reaching 9.5 PSI by 3800 RPMs?

Is this from a low RPM roll?

What I am really curious about is from say a 4th gear roll starting below 2000 RPMs, when do you reach 5, 8, and 10 PSI.

Since I am getting that exact turbo, I am extremely interested.

Thanks!

 

2nd gear pulls

i have an auto so i really cant give you accurate rpm ranges in certain gears

 

That's exactly the range I want and hopefully I will get it because I will have the same set up y pipe and turbo specs wise.

 

it was a sweet setup for a bit. but you get power hungry

 

Cool, I was worried that you might be posting 3800 RPM figures for something like a 4th gear roll (manual tranny).

I am hoping my combo will spool to ~8 PSI around 3000 RPMs with that turbo from a 4th gear roll (manual tranny).

 

the exact turbo is a Turbonetics T3/T4 big shaft 60trim. i have pics on my cardomain in the sig
