Go to extrudehone.com, or maybe search here. It is a machining process where the abrasive is suspended in a fluid, enabling polishing, deburring, etc. in castings that would be difficult to do by hand. They also gasket match the ports. I have no before/after data, as they aren't installed yet.

how much did each process cost? did they do any before and after flow testing?
i think it would be very difficult to get comparison on intake temps as most people here measure intake temps before they hit the intake manifold. iirc....

If they did any testing, they didn't tell me. The woman who replied to my inquiry told me to expect 15-20% increase in HP; when I talked to the guy in charge, I told him how impressed I was with that 
He revised it to 15-20 HP.
Don't know cost exactly; I'll know when I get the credit card bill.
I'll have an idea about intake temps. since I've taken some notes. Problem is, I am also modifying my IC and adding a phenolic spacer at the same time, so I won't know how much to attribute to what.

so pretty much if you alredy had your UIM and LIM polished you would have to polish them again after you do this.

To get the complete effect you should JH all non-radiating metallic portions in the intake path. Although even doing just a couple will probably have a noticable effect on intake charge temps.
I'm looking forward to any charge temp stats you can give us after installation.

built my own engine
for the price i'm not all that impressed....
but it looks good nonetheless, i'd say you could have a custom LIM/UIM made out of tubular aluminum for that price

No way you could fab both pieces for anywhere near that price.

Was that for both the extrude honing *and* jethot coating? How much for just the jethot?
