Air? How much can you draw?need help

QUESTION, MY PROJECT IS A NON-TURBO DIESEL-ITS A 6 CYC DIESEL ENGINE(TRACTOR ) AND HAD 3 CT 2 CYC HEADS AND THE STOCK INTAKE IS ABOUT 3 FT LONG AND ABOUT 3" AROUND , MY QUESTION IS : I HAVE A 3" ELBOW COMING OFF INTAKE AND GOES THREW THE HOOD ABOUT 3" AND I HAVE A 8" HIGH ROUND K & N AIR CLEANER ON IT, A COUPLE OF TURBO DIESEL TRACTOR GUYS CAME OVER AND SAID TAKE THE AIR FILTER OFF AND RUN A 2 - 3 FT PIPE UP AND YOU'LL MAKE MORE POWER, SO WHAT DO YOU GUYS THINK ABOUT THIS ? I TURN THE ENGINE AROUND 2200 - 24OO RPM

P. S.

I CAN'T BUILD A CUSTOM INTAKE BECAUSE IT HAS TO REMAIN STOCK LOOKING AND AS NICE AS MY TRACTOR IS THEY'LL SEE IT OR FIND IT.

Woah... dude don't need all caps, makes it hard to read and seems like your yelling!

I am not sure it would effect flow enough to notice.

Here we go with the cap thing again , not yelling , so please don't send me alot of email concerning myseld using cap's or not - alot of some people on here and hopefully someone will get back to me with some answers and or facts. Thanks bud

The theory is that the added tubing will increase flow. I don't think the added resistance from a extended 3" pipe would do anything. Now using a convergent duct duct just prior to the intake would increase flow. That would be a 4 or 5" pipe down to a 3" just before the intake.

But I am still not sure how much it would make a difference on a NA motor, or even a forced induction motor as the intake just sucks. .

I'm just trying to find out which way i'll get more air ? short elbow off intake into a k & n filter or just a chrome staight pipe up and the air - which will flow more air ?

 

[jakprince]

no doubt the straight pipe will flow more air but you will also suck in any dirt or anything else

Are you talking about a short filtered intake or a tall non-filtered one?

If you are running the proper filter then it won't matter.

running a K&N is like running a open tube, might keep gravel out. as far as more air, they will be equel. if the engine is run at a set given rpm you can cut the tube to length at the resonate frequency. this will give a positive pressure on valve opening.

Well i was running a 3" pipe off the intake threw the hood , maybe a total of 12" and then i had a 8" high round k & n air filter.

Last night i changed things around, still going to use the 3" elbow coming off the intake and going threw the hood but instead of the air filter i put up a 18" high , 4" pipe ( chrome of coarse ) - the ehaust stack is about 10" longer so it doean't look bad.

Just a little different, i like the old john deere's that the guys put twin stacks next to eash other - one for intake - one for exhaust
