polished throttle body pics...
i saw somewhere on here someone ported a 13B intake and a 20B intake throttle body to a mirror finish... i was looking for that pics because i was going to do a better job on mine.. after the removal of the 2nd set of plates can u mill down the inside so it doesnt nessarely have the 3 holes for the plates so its more like one big hole? i would think this would work better... comments? and i would love to see the pics.. hopefully someone saved them to their computer.. 
thanks
thanks

I personnaly would stay away from a "MIRROR" finish in the Intake tract.
To quote David Vizard ( an engine building genius)
"Polishing of ports is a favorite pastime, but polishing ports does little or nothing to improve flow. A smooth, cast finish will normally flow within a hair's breadth of the figures produced by a highly polished port. In practice it is sometimes found that highly polished ports cause problems in terms of fuel puddling and therfor may not, in some instances, produce the results being sought. What is important for an effective cylinder is shape. A ground finish the right shape will produce HP, A polished finish the wrong shape will not."
Even though this was written regarding cylinder heads for boingers, the flow principles involved directly pertain to intake manifolds.

As for flow... if I were to add a mustang TB, I'd use a 90MM single bore plate. Yes, this flows better, no question.

90mm is the Pro 5.0 throttle body, dunno who makes it, but I could find out.
Stock is 65mm or so...
