RPM loss from a stock impeller on a 09 P-X to a 15/22R
Purchased a 15/22 from Meepers (thanks man, just as advertised, new in box) I do 8200 rpm with the stock impeller (@ 100 less in the heat) Just wondering how much I would lose if I install the 15/22.. Would I still go faster if the 22 does say 7800 or so??? I am only looking for top speed... HOW MUCH LESS R'S WILL I TURN THE 15/22 ???

It will feel like a dog, if it tops out at 7800 rpm. I think you will be okay if running a 87mm nozzle. New in box the 15/22 usually are about 14/21 and need a little work to even out the blades.

How many Rpm's do you think I will lose???

Let's just say I do 8200 right now with my set up and a stock prop... How much would I lose??? 100 - 200 ??? Also what would be the best next mod to get my RPMs back up (cheapest mod)

If I only lose about a 100 rpm's then I should go faster with it on right, (therotically anyway) more pitch at similiar RPM's = more speed...

I dropped like 50 to maybe 100 when I swapped to an out of the box 15/22r

How much of a speed gain did you see with the 15/22 over the stock impeller???

Any ideas on speed gain I will see going to the 15/22R over the stock impeller at say 8000 rpms??? Anyone???
