Thread: What impeller?
05-15-2011, 07:03 PM #1
So I thought I got a 15/20 but it looks like this guy is backing out so now I was curious if I should get a 14/19 or a 15/20? I will have an x charger, 42lb injectors, 4" intake and grate. What would be the best option in your opinion? I will not be running a fuel regulator or controller for a few moths until the wife gives the ok however I will be getting one.

I could be wrong but I believe the stock rxpx uses a 15/20.

So the 15/20 is out of stock however I could pick up a new 14/19 non R for $175. Would this be good for now or will I just end up replacing it later. I noticed that there are some guys running the 14/19R with their setups. By the way I will be riding most of the time 800 feet above sea level.

I searched google and found

R&D offers this information to help insure that when replacing the impellor, the right purchase will be made, and performance demands will be spot on.
Progressive Pitch 13-17 over 145 degrees
Progressive Pitch 23 degrees over the last 15 degrees
Total blade length in degrees is 160 degrees
