I would recommend you get a higher KV model to get maximum possible motor RPMs from the 24v setup.
My recommendation would be the 5650 -6D 1800 KV motor. Its a 56mm Motor, more tq, 4200W Continuous power, 50k rpm max rpm.
This motor should rev up to 43k rpm on a 24v pack easily. You are not pushing it too much as far as peak V goes. And remember, this motor will only need more current if it sees more load. So in your setup, it should have no problem giving max possible boost low down the engine rpm. As Engine revs higher, the motor will need more current to keep the boost up. I guess you will reach the battery current capacity at high engine rpm. Then you can start looking at integrating your BoostCaps
.
btw, its a build your own motor so I suspect some build time on it. They might even work with you on the kind of shaft you need for this.
