hey all i just got a second 7afe intake manifold so that i can port and polish and fabricate a spacer for the surge tank.

for those of u who have seen the inside of the IM. i plann on milling down all of those ribbs on the top piece to about 1/3 of it's original hight. then filling in the rest of the space with JBweld. (to add more strangth to the metal since i took out most of the rib structure, and to make it smooth.) then sanding the whole thing smooth. on the lower part though i have som questions.. there are two huge blocks that from what i can tell, do nothing for the structur of the piece, and it takes up space inside the tank. (i'll post pics if i can). i plan on milling that out aswell. to finnish out the smooth form on the inside. (would this be bad thing?)

i am also going to make a spacer for the tank useing the gasket as a pattern.

i am going to make it out of hardboard or MDF and permiate/cover the piece w/ JB weld. (to keep the part from falling apart, and to give it heat resistance, and to make sure that it give a tight seel.

the questions that i have are...

whould these modifications (significantly) effect the way that the vacume tubes off of the IM work? would it should i get any negative effects from dooing this?

thanx in advance for any info .... i have done a search on the forums but found nothing on work of this sort on the 7afe IM...

thank you..

whould these modifications (significantly) effect the way that the vacume tubes off of the IM work <---- yes it would effect it. how NO CLUE

should i get any negative effects from dooing this?
yet again NO CLUE

i can see this being a VERY bad bad idea.....you have this idea you can jbweld everything...not so and not the best idea.....
especially with MDF board there is a reason why you NEVER see this inside an engine bay....it NEVER belongs there...IMO that would be something that you need to rethink and use the proper materials..aka METAL not sum JBweld coated wood.... rethink your material useage in this lil endevor and see if you can find airflow charts and such online for the IM and what benefit it might actually or not actually have....if you can't find anything go talk to a local performance shop

i see no reason teh vacume lines would be affected, vacume is vacume.

unless your moving them or plugging them up or something.

also dont use any kind of wood or MDF or hardboard, whatever use metal.
