Max Hp numbers from a T-25 - T-28
Just curious since these turbo are a dime a dozen and everyone has ran one sometime or another I just wanted to know what was the most power you have ever made using one of these turbos.

edit: this was from a bb t25

The most i've seen from a t25 is 275whp. The most i've seen from a t28 is 330whp by yours truly.
