thinking about picking up a .50 trim for my set up. I was wondering when you guys were fully spooled using this turbo and how much power were you making 10psi and under.

 

some ones gotta have some info on this, i know there is a lot of you out there running .50 trims

 

depends on the AR of the housings.

general "50 trim" egay turbos will hit spool around 4.5K-5K. Sometimes earlier or later; depending on motor.

The hotside has a greater effect upon spool. Also keep in mind that boost threshold/spoolup is not a constant, but dependant upon gear and load conditions. A .48 turby would probably choke it up top but have a zippy spoolup, a .63 would be just about optimal for a street gsr, and the .82 is better suited to bigger compressors. A stage III wheel is a good match for the 50. Keep in mind that a 50 trim is actually on the small side for a gsr.

save your $$$ and buy a real turbo, don't spend your $$$ on ebay xpower etc pieces of ****

 

highly dependant on set-up and a/r as well.

I've seen some hit full boost just before or around 4K and i've seen some hit just before 5k. Depends on the setup and load conditions like stated before..

you could get the 57 trim with the .48 ar and spool should not be to bad i am runnin one on a stock ls.....what motor do u have?

what if its a .50 trim with .50 a/r. What about that? Whats the spool on that. And what kind of power can I make only boosting 7lbs.

 

on my set up i will be running a t3/t4 .50 trim a/r .63
