i meant who cares if you only get 1 or 2bhp more because it only costs £26, not who cares about the actual modification.

i meant i care if its done witha dremel or on a milling machine....
If its not a bigger bore then you might get a tiny bit from the polishing. but to be honest you will get as much by removing the other half of the spindle and cleaning the ornginal carb without all the tedious polishing.

Look on the pic of my original one, there is a restrictive lip that is ground down which in essence makes the throttle bodie bigger allowing more air in. Ask spencer he will explain. You cant argue for £26 anyway.

Im well aware of the lip, and cutting away the useless bit of the spindle etc... i was just interested to see if its bored or just cleaned and polished.....

on the bike carbs its only the actual venturi thats bored then usually finished by hand while spinning in the lathe.
in reality its just doing what the manufacturers originally should have... 
in saying that, when removing the lip thats the result(better throttle response) i have felt for myself, and removing the spindle helpf with airflow at WOT so it makes scense anaway.

throttle response feels better as the manufactures put that lip in to give a smoother throttle.

what you saying, that cleaning it and removing the bit of metal is what your getting for the £26?

looks like it...
william.. im not sure it it was left/created there on purpsoe or not? its possible it was designed with the casting flash there for that reason although it does sound quite a  idea for citroen...

Heya,
we're going to be testing some Saxo exhausts / manifolds etc on a rolling road soon. If you like we'll do a back to back test of a ported TB if you send us one (We'll return it after)

I think it's important to test a standard throttle body against the ported and polished one, as long as the standard one is *THOROUGHLY CLEANED* first and de-gunked.
I wonder how much of the noticed improvement is because the TB is lovely and clean?
I cleaned out mine recently as it had loads of gunk in it, and afterwards there was amuch crisper feel to it, so bear this in mind.

I had mine off the other day when I was in at the ICV.
It seemed fairly clean anyway, I'm all up for members offering a service to users but if its merely a case of cleaning it...
Mine was 3 alan key bolts I think.
