Impeller pitch ?

[Piney]

Greetings--

A few questions--

What do the numbers represent when refering to an impeller's pitch ?

What is the stock impeller's pitch on our 04 GTX LTD ? 12/20 sound correct ?

And... one last question--

Changing the impeller's pitch to one with more low-end accelleration/power--
Recomended impeller ?
Will it need a new intake grate ?
We don't usually ride in rough water.

Thanks !!

Bumping this question, anyone have an answer about the numbers ?

The numbers are the degree angle of the blade. The first number is the leading edge and the second number is the trailering edge. I will post you a pic later, wrenching for a bit.

OK, thanks.

Do you also know the effect of the the two?
If i go from 12/20 to 13/20 or a 12/21, what difference am i gonna feel ?

And then theres the bladenumber...
Is there also a way to compare 3-blade againt 4-blades ?
For example a 4-blade 12/20 is eqvivalent with a xx/xx 3-blade ?
