well my manifold is totally done now..im really happy how it turned out. i have about 20 hours in it though (kill me please) i learned so much that im sure if i had to do it again i could easilly cut 5-6 hours off.

anyways.....after all this cutting, grinding, filing, sanding, porting, etc etc.......does anybody have any good sugestions on getting all of the crap out of the inside? each peice was cleaned individually before it was welded..so its not real bad...but i know there has to be some little crap in there. should i just use brake cleaner, degreaser, water, and air compressor? i plan on having this manifold jet coated as well....i wonder if they do any kind of cleaning process before they do that? any sugestions would be great! Thanks in advance!

 

brake cleaner and an air compressor. You could bead blast it and get most of the surface blemishes off.

 

If it's going to be jet hot coated then i'm pretty sure they blast it before hand so some carb cleaner before it gets to them should be plenty.

 

well, you'd hope that they would media blast it, as soon as i pressed post that ran through my head, oh well, i'm too lazy to go back and edit.

 

brake cleaner, degreaser , then wash it out with the coin carwash high pressure hose

 

u could soak it in muratic acid . sp.. crazy crazy acid toxic stuff .. but will clean metal like no other .. it etches the metal clean of all contaminates .. wear goggles , mask, gloves .. soak it .. u will instantly see the stuff start to steam and bubbel .. dont smell the fuems .. u will get a head ach for a week .. wash off with a hose ..
