4age flow figures

[WhiteSx]

Hey,

I'm chasing flow figures for a smallport 4age head, std and ported. Doing some number crunching and need those figures.

Also anyone know what the flow rate of a silvertop 43mm itb is???

thanks

Dave

I flowed ST ITB's years ago, from memory each throttle flowed 256cfm @ 20in H2O. Maybe search old toymods forum, I'm sure I posted it on there, I'm sure about cfm but not test pressure.

largeport, but since it is just the bowl and transition part of the port, it might be useful. The valves were not part of the porting work
