Front Facing Intake manifold Shapes what do you like?

[sethron71]

Hey boys and girls,
Just wanted to see what everyones opinions are on FFIM plenum shapes. This is solely from a looks stand point what do you prefer?

Do you like round:

Or Do you like square:

Just curious as what people think looks best. I personally like the square not only for looks but also from an engineering stand point and volume vs. dimensional size! Appreciate any opinions!

Thanks,
Seth

I like the style of the short runner that Ron Ramirez does.

I hate the squared ones.

If someone would start copying the RR short runner I'd buy one.

Round smooth looking one FTW!

but on a side not whatever does the job kinda deal. but round style if allowed.

 

[Kristian_Wraae]

This one

Notice the bracket that drops the alternator AND retains the A/C.

I like the round..Like the RR longrunners.

I like the round..Like the RR longrunners.

also better on airflow

 

[BorHor]

Round looks 100x better.

 

[88YotaTurbo]

I like them all, But which one actually provides the best performance??????

 

[Big Wang Bandit]

Round is best

 

[prism1]

round definaty

 

[sethron71]

Well I take it round it is.

Performance wise round does not neccessarly perform better.....

That shape is inline with the flow plus it is boosted therefore the plenum is full.

But it is good to know.

BTW the way these are ones I build I just wanted to know what people like. The round one is called a medium runner manifold and has the same design and flow characteristics as a short runner manifold yet is rotated up to allow for simply lowering the alternator!

Thanks for the opinions!

Data to back this claim up?

I'd rather have a square one since those are probably more easier to make

 

[Dylan JZ]

round one.. its not that its better, its the fact that those square ones, regardless of your awesome welding skills still manage to look horrible.

 

[KevinM]

I've always liked both designs that Ron R made, so yeah, round FTW

 

[alloyguitar]

I'm in the process of building mine, and it's going to be square.

But I'm also going to smooth out the welds for a seamless look and powder coat the whole thing black.

But hey, to each his own.

anyone that get's rid of the stock 7m plenum

anyone that get's rid of the stock 7m plenum

there's your answer!

Data to back this claim up?

i dont have data to back it up but im sure its for the same reason water move faster and smoother through a round pipe,or the same reason air flows better through a round air ducts in more expensive ducts

i like the square ones i dont know why i just do, i think its because round is more show and square seems like it is right to the point.
