Anyone tried this crank evac idea yet?

Have you noticed on some dragsters they've run lines from the collector area of the header to the valve cover breather? This uses venturi effect from the exhaust to provide a low pressure (suction) to the breathers on the valve covers. Kind of works like a crankcase evacuation pump only no moving parts. My friend installed this on his 59 Chevy and from what we can gather it does provide some vacuum any where from just above idle to about midrange then as the revs go higher it kind of gives out. Has anyone tried this on their mustang yet? I'd like to know if you noticed any positive results. Most likely this will be used on street/strip cars with the emphasis on strip.
