Even with a T4 .90, it would be a nightmare

I believe tampabaybill has an S471 primary. The thing that sucks about it though is the slip on discharge instead of a V-band.

An S471 has a primary (compound set up) is nearly unbeatable.... but as a single, no.

I'm feeling chatty

Would a spool valve help or is it entire too lofty of a goal?

I'm ran a 67mm as a single with stock timing. Totally sucked. It wasn't impossible to drive, but it sure want fun either.

With a p pump it will have more usable rpms so that is why I think it would be worth trying for the price, depending on how much fuel he plans to give it.

The spool valves are a cool idea but for the price I don't know if its worth it.

I've talked to folks who have used the spool valves... and they all seem to say that they are amazing.

How does a spool valve work???
