What is the next size up from a 23 plus mirage
I can only seem to find 25 plus. is there a 25?

The plus has nothing to do with the pitch size. The Mirage was the old design. Mirage Plus is the new current design. There is the old design Mirage 25.

The one in this link is left hand. Just saying there is a Mirage 25. You would probably want a Mirage Plus 25.
How many RPM are you turning the 23 Mirage Plus?

Adam,

You said you were turning 5000 with the 23 you got from me, are you trying to turn more, or less rpm? Going up in pitch side(from 23 to 25) will lower your rpm.

Trying to get more speed with a 25 but yes lowering the rpm, i figure if i can run a 25 at 4800 rpm ill be fine

I am turning a labbed 23 mirage 4950 rpm now, i have a 23 plus stock in the mail, just fig ill test them all and then sell what doesn't work ...

Rule of thumb one inch of pitch changes RPM by 200. If you go from 23 to 25 you will probably only be able to turn 4600 RPM.

Unless he gets the 25+ labbed, then he may be 4800

OK,

Just making sure you are going the right direction.
