I'm sorting through some of the (Y's) I have to find a couple of good ones. What is the actual size that the restrictor hole was from the factory? I know some of the ones I have are too small and need to be drilled.

I've fought with boost problems and it's comming to an end NOW!
What bit size would be correct, any ideas?

TIA :cool:
 
The diameter of the orifice in a properly operating assembly is about .050 inch. I drilled mine to .048 or something like that, if you have a 1 to 60 drill bit set you should be able to find something very close.
The orifice in the defective hose measured less than .035 inch
