That’s an open book question. But ideally that size from what I’ve seen in the tractor world, once you are around the 2000 mark you go 32s then 34s, then 35s comparably to scale. The biggest I’ve seen in these small cube engines is 38s in a triple feed, I know a couple of the older scheid ss builds used a dual 39. But I would imagine on a ss build 2400 shouldn’t be out of reach, maybe a little hot on the exhaust gas.
