Ok guys we been toying around with a larger intake manifold for my pulling truck. The P-pump lines are hard to work around but I think we have it whipped.

Here are some pics while test fitting tonight. We more than doubled the output area of the manifold.

It stall has a little work left to smooth it out before painting.

Does it look good or bad?

Just looking for opinions.

 

I think it looks great bud!

 

since you were making it why didn't you center the intake, or make it more like the banks setup for a 12v where it puts air to front and rear of the head?

 

The P-Pump lines are in the way. We used all if the open area possible. Only other way it could be done is if we made the intake and custom bent all the lines around it.

 

Why not curve the edges of the box instead of making them square? The flow around corners like that with the sudden change in direction as it drops down into the stock manifold would make some WICKED turbulence at high flow volumes... This would most likley cause you uneven pressures or fuel mixing issues.

I always wondered why no one just took 6 curved pipes and tied them into one... Like a backwards header... Each pipe feeding a relative cylinder.

 

My buddy that built the manifold knows nothing about this sort of thing. I just showed him where it went and explained what I was wanting the best I could. He defiantly made it to blocky and I am having him make a change to it for hopefully a little smoother flow rather than the air flow hitting the big squared end next to the valve cover.

 

Could you feed the manifold plate with multiple mandrel bent tubes?

After you mentioned this in your last post I already have have come up with a design in my head for this. I am going to work on it this week.

 

Bend up some custom lines and make what you want...

 

It looks like the air could be turbulent in that intake. Seems a smooth radius is the way other intakes are being built. Smooth is harder to fabricate though. It looks like it will get the job done though!
