still looking for more on it

12 psi.... (freak) me want, me want! But I think the 10 psi cut is wrong yesterday I tried at 10 exactly and nothing happend. I would not drive that much boost that long though, as you are not sure of the engine can stand that much pressure for to long. But again wow, 10 psi pulled me in the seat quite nicely i could only imagine 12psi. (stoned) hmmmm 20psi .... could easily shut down the magic turd.... need more boost...... want more boost.... will need new engine afterwords.... who care i'm doing it!!!!(stoned) (woowoo) Just kidding but after a major engine build up I might.

your funny.

more info on the T25:
more compressor info:
inducer diameter: 1.66"
exducer diameter: 2.14"

turbine info:
Wheel trim: 62
Exducer diameter: 1.64"
Inducer diameter: 2.09"

housing, flange is T25.

interesting note: there are other better flowing turbos that use the same flange. the T28, JWT 650, and HKS GT2835 are 3 turbos that use the same size flange. now i'm wondering if these turbos will fit.

now if you can get an A/R ratio we will be in buisness

 

[AFaceInTheCrowd]

on it

 

[AFaceInTheCrowd]

wow that was easy:
Compressor A/R: .80
Turbine A/R: .64

 

[perfworks]

if you dont mind me asking where did you get this info?

 

[AFaceInTheCrowd]

on the net http://www.gcg.com.au/technical/garrett gt ball bearing turbos.jpg , why?

 

[perfworks]

just curious.
i couldnt find any info on it when i serched today i guess i wasnt looking on the right site.

 

[AFaceInTheCrowd]

so uhh i hope my efforts are not wasted. what can we do with this info.

 

[perfworks]

did you get any compressor maps in your quest

 

[perfworks]

oh yea by the way nice job finding that info man!

 

[AFaceInTheCrowd]

no, unfortunately. the 30 sites i visited had no compressor maps available. just prices and applications and a little data. the data is just for consumer purposes and not tuning, so there were no compressor maps. i searched for them like 20 times and got no hits for the t25

 

[AFaceInTheCrowd]

thank you.

 

[AFaceInTheCrowd]

so uhh, what are we gonna do with all this info?

hey face try this
is this the same turbo?
im pretty sure it is.

 

[AFaceInTheCrowd]

i donno, if thats the turbo in the picture, it looks different from the t25. and thats a really small housing, might even be smaller than the t25. that's a flow map. different from a compressor map. compressor maps show peak efficiency, peak revolutions and the all important "efficiency island" or as i call it, the g-spot.

 

[perfworks]

from what i have read on the MSP it is a GT-25 right?
well if thats true then thats the turbo.
the t25 is a little diferent.

 

[AFaceInTheCrowd]

i always thought it was a t25. and the turbo in my car looks different from the turbo in the picture.
