Shoup has a sprocket that gets it to 34K. I built one before they had it with a hex shaft welda hub from one stare and the sprocket (40 chain sprocket works fine with the 2040 chain). You could make any thing you want so long as the big sprocket and chain don't hit other parts, like the other shaft and the housing. You might need to make a new chain length and do some computation.
