Turbo KA Power...

I want to see what kind of HP range were looking at...
Stock Internals
5-6PSI
200-225
7-11PSI
230-265
12-16PSI
270-300
17-25PSI
310-350
26-31PSI
370-435

Is this a question or what you have figured? Because those numbers are off. There is no set power level for a set PSI. Airflow is different at set pressures from compressor to compressor.

And is that whp or chp?

Those are just all guesses. I dont want definites i just want peoples numbers like NissanFanatic got from 5-6 PSI and then at 9PSI what he got or TatII what he got at his Boost levels. I just want a general range at what ill be looking at to get close to my friends RB25 Swapped 240 hell be getting it done in the beginning to mid August.

there are too many different variables that will detirmine the HP rating at a given PSI....you need a more defined question.

Then get a generic idea of what turbo you will be running...

15 psi can range anywhere from 280-350whp depending on turbo, and supporthing mods. if everything goes well i'll dyno this week and see how much power i'm making at 14.5 psi. ( i'm guessing 300whp ) but anthony made 345whp from 15 psi.

you can't ask based on psi alone you need to list you supporting mods and turbo, you'll probably get the best info from the ka-t guys here, ka-t.org might help don't know personally though

7psi on a T25 is going to be alot different from 7psi on like a T88, its the difference in flow of the turbo

and someone correct me if i'm wrong but i don't think that the stock internals will hold up to good past like somewherin 15-20psi range

usually with good fuel management, the stock internals can handle 350whp pretty decent. whatever psi that is, it depends on the turbo.

Power=airflow. Plain and simple.

They have held up to 450...I believe...
and lets say...

Stock Internals
GT28R DualBB
Turbine
-Wheel: 53mm w/ 62 trim
-Housing: .64 ar


Compressor
-Wheel: 60mm w/ 60 trim
-Housing: .60 ar

JWT or Enthalpy
550cc Injectors
255L Fuel Pump
Small FMIC
5-6 PSI and then 12PSI...

They have held 404whp documented.

5-6psi, prolly about 220-230whp
12psi, prolly 320-330whp

GT series turbos are very efficienct making more power at lower boost.
