T-Trim owners,

i have a t-trim vortech with a 4.2 inch pulley on my ap1. Im trying to figure out what my max boost is but cannot find a chart for t-trims. Can someone help me out? My goal is 12.5-13 psi. Thank you

 

Take what you have and put it on a dyno that reads manifold pressure.
What ever boost you hit at redline is max boost with that pulley. With this information you can make changes to change the boost up or down.
From a calculations point you can figure your impeller speed.

A 4.2 inch pulley with 9000 rpm redline would give and impeller speed of 46,286.

The T-trim tends to like higher impeller speeds and you would be able to increase the impeller speed quite a bit if the boost is too low.

 

You should be able to run that boost on the stock S trim with no problems.
