I have 21 eliminator daytona with a 300x. I can turn a 14.5x30 lightning @ 7000rpm but can only turn my 15x32 spinelli @6000. I have sent my prop out to have 1/2 in dia & thinned out & sharpened. How much rpm will i gain.

In theory, every inch of pitch is 200 Rpm's & each 1/4" of dia. is 200 Rpm's. doesn't always turnout that way.
