opening up my stock intake plenum.

so as im in the process of replacing pistons in my rat rods 12v and as usual, while its apart and in pieces, i figure i might as well modify things more.



while looking at the crappy factory intake i found a few placed i could cut away to get some better volume and flow.



took the plasma cutter and started hacking. i cut open the top at the #1 and #6 runners to add some vlume and also gain access to the huge brick that blocks flow to #1.

i cut that out as best i could with the plasma and then used a cold chisel and hammer to break the rest of the cast off as the plasma couldn't cut as deep as i wanted and it was hard to get the torch in there all the way.

i then cut out the big brick that makes up that extra oil filter thing below the intake. i cut it most of the way around as best i could and then used the chisel again. after i cleaned everything up with a die grinder and while the area was hot, i welded up the holes that were left after cutting up the secondary oil filter area.



then today i took a piece of 1/2" aluminum plate and made myself a longer intake plate that will eventually get 2 ports for a twin ram style feed to distribute air more evenly. best part is, i can still use my factory injector lines doing it this way, and it should flow WAY better
