5.9 header

Do I need one of these?

 

[TKingsbury]

I can't answer your question, but it looks spiffy.

I'd buy a tig welder before I paid someone 1200. 00 for one of these

Cast iron was good enough for Sickly to make 800 hp.

Amen to that!



I used to have a turbo charger book from back in the late 70's, in it they suggested that flow wasn't necessary for optimal turbo efficiency, but keeping the heat in was the most beneficial.

Read the ad you could get the idea this individual doesn't realize that the Cummins has a built in oil cooler.

Good point for Sickly

The title says it all "Sickly made 800hp

flow of air

When Mack started putting turbos on their engines, they did a steel INTAKE that was somewhat more aerodynamic than their cast intake. The last time I looked at a Mack, they still use that. There is no way to accomplish that on the b engine with the intake cast as part of the head and in fact, there may be no gain on the intake side either. I have wondered about the headers myself and if there is any gain to be had. I remember an article about someone milling the intake off a six cylinder Ford engine and making a tube intake. That might be a project for someone.



800 horsepower!! I can just see the Getrag puking its guts out.

Can you machine off the cast intake on a 12v like Banks did on his 24v? That header would make a heck of an intake.

 

[CDegner]

Considering it is for one of those new fangled over-valved engines, the answer is nope!



I like his part about not needing to describe the performance gains. Probably means there aren't any.



A little porting on the stock manifold and things are sweet!

"Can you machine off the cast intake on a 12v like Banks did on his 24v? That header would make a heck of an intake. "



I think I will get a junk head and see what it looks like cut back. I am not at all sure what would be left to bolt the header onto. I doubt that the header shown would work for an intake but something similar might be fabed to do the job.



I can see where the turbo would negate any gain on the exhaust side but seems to me that a tuned set of tubes on the intake would help.



Any one have a picture of the Banks mod?

I hate to be the nay sayer here but, the whole point of a header is to equalize the back pressure, control the back pressure, and doing so cause the power/torque curve to move to your desired rpm with respect for the increase in CFM.

Not to mention the heat loss due to the thin wall tubing.

A modified stock or ats is the answer.

If you want to keep heat in use ceramicating or header wrap. To think that a turbo motor won't benefit from more air in and out of it is ridiculous.



Just because sickly didn't have it nobody should???



Joe, when are you gonna make some power BELOW 3000rpm? I can still build a 400hp truck to SPANK sickly at the track.



The prices are way steep.

It will benefit from more air in and out but a header on our trucks is not going to do it for you.

Just because sickly didn't have it nobody should???.

Who said that? Hmmm, cast iron. Joe might be on to something. Funny, none of the other high HP 24V trucks around here are are running that contraption either. Maybe they do around your neck of the woods. Cow Town has been known for some unusual things in the past.

Hey, what do you know ... we agree on something!

At 290 hp you're right, it won't help . If you have a motor that will flow more than the manifold you will gain considerably.



The goal is not always more peak power but more sustained power. If you can lower egts to the poin that you can add more fuel safely then you are gaining a lot.



FWIW,

Humm, 290 hp. Ok, well, at 334hp with low pump settings, a stock converter and reving to 3600rpm and using a stock manifold (ported) with a modified 14cm housing attached to a PDR hx35, I still don't feel the need for a header.

Now before you retaliate, think of this. When you can keep your drive pressure/boost pressure at or near 1 to 1, where will you gain?

Not to mention the pleasure of constant exhaust leaks, and rotting and cracking tubes.

For the high rpm sled pullers that don't care about down time, I'm all for it. I use a header of one type or another on most race motors I build. Be it a single 2 or 4 stroke engine, or a blown big block. It all comes down to the question, will I gain from it?

If someone would build one and show before and after results, and show gaines, I would be one of the first to bow down and beg forgiveness.

I may be an old dog, but I can still learn new tricks.

Oh, I forgot to add, max EGT's are 1250 at a gross weight of 15,150 going up snoquallime pass
