Pulley Size for Ford Racing Supercharger

[travelers]

I'm looking at a Ford Racing tuner supercharger 2.3 which doesn't come with a pulley. Anyone know what pulley would be for 7psi? I shot Lethal Perf. an email and they said a 3.875 they think. I also read a 3.625. I didn't get a chance to call Ford racing on Friday so if anyone has that info it would be a big help.
Thanks

It's 3.625.

The 9-psi one is 3.375, so the 7-psi one would definitely bigger.

Sounds to me like Mystickeith50 is right ^^^^

Of course it all depends on your setup. I had 3.375, 3.25, 3.125 but had them with different setups like long tubes and bigger throttle bodies. I would lose a pound with the long tubes but I gained a pound with the bigger throttle body etc.

I do have ARH 1 7/8" headers and I was thinking of going with Ford racing 62mm TB
