Throttle plate spindle leaking under boost?

I'm running a cenrtifugal supercharger on my 4.6 V8.
Just rebuilt my plenum and been thinking does anyone have boost leaking problems arround the throttle plate spindle? I hope to be getting 8 - 10psi.
There is some very slight play in the spindle. If I should seal it any ideas?
Thanks,
Tom.

You should still make reasonable boost. I forgot to refit my 1/2" air temperature sensor to the plenum and still still made good boost, I could just hear a whistling of air.
It would have to be pretty sloppy to leak badly and I'm yet to see one that is worn even slightly.

The only times it would be a concern....
would be if the spindle itself was so bad, the throttle blade wasnt working properly.
Or if it was a carbed blow through setup, where lots of fuel was getting expelled from the spindle.
other than that, I wouldnt worry. It will be so small as to have zero impact.

Here's the photo's of me pressure testing my manifold, you can see the leaks I had and also the great big air temp sensor I left of once and still made power.
