Jimmy,

The Jett .50 will do it with some minor changes to the timing and tuning. The current timing will not turn up there in the rpm department, but what you can do is call Dub up and tell him that you want a custom Jett .50 with higher timing, and tuning it for maximum rpm's with the 9x8 prop (I don't recommend 9x8 for high rpm, but instead use a 8.8x9). This will sure get you where you wanted, but you may have to sacrafice a lost of warranty for a customize high performance motor. Unless otherwise, stated differently by Dub himself.

My current Quickie Jett .40's will turn a 8.75x9W at 19,500 with no problem at all. So for the .50, it's no big deal. Just need a little tweaking that's all.

Hope this help!
