I have a 386 2003 Sonic with twin 525's with ITS extension boxes. I'm currently running with Bravo 28 Props turning 5000 rpm. Any recommendation's on if there is a better prop?

You forgot the third equation: what speed are you getting with the current set up? Do you want more speed, low end or what?

ther are no stupid questions





























only stupid people!!!

just kidding
call thottle up and have them tune your prop to got 200 more rpm

Hey OnePass - Welcome and thanks for asking this question. I have 2004 386 and have been wondering if a different prop set up would be something to consider. I don't remember ever seeing anything in the Sonic forum on this.

The new round ear Hydromotives seem to be working well. Good all-around performance, and good top speed.
