Default Intake Kegger

I was wondering what would you use to fill an intake manifold ?

I was thinking of fiberglass but was not too sure if it would hold up to the changes of temperature with the metal expanding. I had also thought of JB Weld.But it would take like 20 tubes to fill and would be a long to dry. Any suggestions, I would like to fill a few areas in my intake manifold for better flow to fill in some of those corners.

I read somewhere about an epoxy but did not say what kind.

Try calling Hughes Engines and ask what they use.

If you know anyone that welds aluminum why not just have some pieces bent and weld them in?

Or can you not weld the type of aluminum the intake is made out of.

Welding would not be a good thing there is always the chance of warpage. Plus if I were to just going to pay someone to do it I would just buy a new intake. I just want to experiment, I have some ideas to improve performance.

I have a 318 so making the plenum bigger would change the peak to a higher rpm. So what would happen if you were to make it the same but make the plenum area smaller.

I would fill in the corners, fill in around the runners so there is no corner around the runner try to make the air as smooth as possible. Since it is not a carburated engine you don't have as much need for turbulent air for AFR. So instead of this block square plenum area try to make it a little more rounded and contoured.

I know a guy who used Road and Bridge epoxy. Held up well according to him.

I had a Hughes modified intake. From what I could see with a mirror, the epoxy was a tanish color. It was very hard to the point it couldn't be marred easily using a screwdriver. I reallize this doesn't help much either. I would just lookat msd sheets and try to findsomething very hard, very adhesive, and temperature resistant.

Google "Devcon" and check out the info. They have an excellent high temp epoxyfiller for aluminum. It's not cheap but it should work.
