Engine/Transmission (1998.5 - 2002) The Search for Max H.P. 24 Valve

[RacinDuallie]

And the end port feeds 1 and 6=

 

[RacinDuallie]

I'm porting this head to flow more for max h. p. for street use..... I wonder how those huge ports you have there would affect spool up on the street? Drivability must not be an issue there, Greg you said you get towed to the line and towed back to pit after run right?

 

[RacinDuallie]

That was a junk head,

You said enough with that statement Greg

The intent is to make the port as big volumes as possible. I believe if you had 400 or even 500 CFM air flow you could still drive it, and it would be as tame as the fuel system. As far as spool, I believe it will spool quicker, and smother, I am going to loose a lot of boost numbers, but gain total air flow, I am even considering running a single using the BB

WOW this is a cool thread!!!



Too bad my G. I. Bill cant support my Diesel Addiction!!!!

Little by little- Diesel Freak- Nothing wrong with that!Oo.

I thought the same thing and my solution... ... .comunnity college diesel technology program at 2k a semester and 1300 a month from the gi bill... . best I could come up with. If nothing else its a step in the right direction.

And my intent is to show what could be done and still drive down to the local store for some milk- and have reliable power to go to the track, without worrying about thinning out the casting so much that it'll lead to your head cracking- the last time I checked you only drive Dr. P's truck 1320' at a time so I don't think you'll be heading out for milk anytime soon... .....

 

[DieselMinded]

Cylinder #1 has an obstruction of the intake port caused by a casting boss for accessory mounting bolt placement plus a forward facing valve port which causes the intake air to run a maze to reach the cylinder. These reduce the airflow to the #1 cylinder, causing it to run richer than the other cylinders. Often, the exhaust manifold gasket has been cooked on cyl #1, while the others are fine.

You guys say CLY. 6 also runs hot . . why couldnt you run 6 Small airhorns one to each cylinder ??

Hey Duallie I thought this was the max h. p. thread not the streetable milk getter thread will you please make up your mind are you looking for the maximum h. p. or the streetable h. p. just wanting to know thanks Aaron

It's not The max head cracking thread... ... ... ... .....

If that's what your after then maybe Comp will start a thread for you... ... . :-{}

Me- I want to have Max H. P. and still be able to do the normal things we bought our trucks for- like going for milk. :-laf

To hog a head out like what Greg posted- I question the long term useage of hogging out a port like that- if your only worry is to have Max H. P. for 1320' at a time- then ask Comp to start a All out Race H. P. 24 Valve Thread-

And he did say the head was a junk head... ...

If you want to have Max junk- I don't.....

 

[RacinDuallie]

To the members that have been watching this thread with interest:

This thread will continue on minus all the prior B. S. that was inexcuseable on my part.
All that B. S. did for me was distract me from the purpose at hand, and that's all it was- a distraction. So continue to follow this thread if you were interested in it like I am. I have lots to discuss- minus the distractions.

 

[RacinDuallie]

Now that that's out of the way. Let's get back in the garage .

 

[RacinDuallie]

Here is yet another restriction in the cylinder head that needs some tending to. How bad is it? You be the judge! This is the last restricted port on the head- intake side for cylinder # 6

 

[RacinDuallie]

This is the same bowl, looking in with alittle bit of an angle, for a better look-

 

[RacinDuallie]

Now that the port mouth has been blended, the flow comes in and hits this restriction. :{ !

You will also need to take care of the bowl area too.

With proper tools you can also slip up thru the bowl to blend in the area of the port that can't be reached from the port mouth side.

 

[RacinDuallie]

What's interesting here is Cummins could have very easily went in the bowl area and machined this restriction out of there? Not too hard when you have the machining equipment that they have. :{ Instead it's up to the person looking for improvments.
You can easily increase the flow rate here by 25% or better and pack more air into cylinders, when combined with port mouth work. And you have yet to *play* with valve cuts to speed it all up! Think of the benifits all this work is giving you!

DieselMinded-
Stay tuned!Oo. I'm working on a cure for this problem, The Ramifold.
Started to do the rough work on the prototype piece. The Cylinder head we have now to deal with is meager at best. I believe The Ramifold will be a very popular piece for the people who use their trucks everyday for whatever reason- towing, hauling, normal cruising and mainly racing. Like the gasser engines have their Edelbrocks and Weiands to increase they're abilities- I'm looking to market a selection of Ramifolds for Cummins Diesels.

 

[JDailey]

Explain this "Ramifold" to me please. You are talking about cutting the casted plenum off on an average street truck? You act like you are inventing this... . hate to burst your bubble.

 

[RacinDuallie]

Nope- If your any kind of a gearhead- one can easily see the problem with the cylinder heads breathing abilities- or rather lack of breathing abilities!! It's been out there since Dodge/Cummins released them to the public. When you increase the H. P. potential in these Cummins' you can qwickly reach the point where the head is the major source of the power building problems(lack of breathing).
Yes! I'm talking about cutting that plenum off- and throwing that 17. 3lbs. of pig iron in the scrap bucket, and bolting on The Ramifold!! Not a welded up sheetmetal type intake- like you see out there now- but one that's already 'casted' ready to go, so if you know of one like THIS- that one can call up and order and have delivered to ones door in 2 days then o. k. my bubbles bursted- but I think not.
