Intake Question - Removing the hump

[dank GN]

i have removed my egr hump in my 87 manifold . what i did was take a small piece of sheet metal and some jb weld and cover the hole and smear jb weld all around it so it was air tight . then after it dried i smoothed it out with some sand paper . not sure it made a giant difference but i felt like i was accomplishing something massive lol

I did the same thing, I did my heads too, bigger bell between the turbo and manifold. made a huge difference. 5lbs feels like 10lbs now. I have other mods that help too though so..

Very Interesting train of thought, Mr. Turbo Riviera. Perhaps someone that removed the whole hump from their manifold could chime in with their results?

I really appreciate all of the input you guys are giving me on this.
Thank you!

This is what I did..

I have decided that I am going to port my manifold. I am planning on pulling it off next week, so I still have some time to decide exactly what to do with it. I am also going to have the EGR port welded shut, since right now I just have a block-off plate.

Also, if I can sell my winter beater, I will be shipping my stock turbo to Limit for some "improvements."

By the why that's awesome man. That was my first attempt. Since then I have removed the entire egr hump. The ports subsequently are bigger. I can't remember who it was, they wrote a bit how the intake is designed to flow AS a high pressure area. So I thought why not try to reduce the drag between plenum sides.. I did other things as well at the same time so I couldn't say how difference it made. However as a package I'm really excited to see how well it tunes..
