Ported intake???

[mjc1241]

Does any vendor offer just the 6.1 ported intake as opposed to selling it in a package with the heads?

[gremlinsteve]

port matching or fully ported intake?

We have done some intake porting, and we can get it done for you with a quick turn around too.

Jeremy @ PPP does CNC ported intakes.

I think Josh at High Horse does intake porting too.

HEMI SHOP, PPP, and HHP are all cutting the intakes open and fully porting each runner and re-tigging?

Impressive!

I thought we were the only ones............

We are not cutting the intakes open, it's not needed and not worth the time or the $$. I am also not certian how the intake would look once cut in half and welded back together. Stu does our porting but I think there are only a couple areas where porting would help the 6.1 intake anyways...

I thought thats what extrusion hone was for. Cutting open an intake and polishing the intake runners? Interesting, but I would like to see the before and after numbers to compare the $$$ to hp/tq number increases.

Thanks for the input. Looks like an option.
Beast 2, what is your expceted turn around time?? Can you also PM me with the expected cost??
Thanks in advance..

Cut it open and weld it back together.........holy chesses batman, can you say $10K intake.

Sorry Lee and Steve, ya know I luv you guys, but damn, that's nuts. Port match it, take off the bottom, blend the bottom of the runners in the plenuim and extrude hone the damn thing. Just my $.02

we can also cnc your intake and heads if you feel that is the best route. i have access to the machines with 2 new ones showing up at the shop feb1 07 also.

we can supply you with a fully ported intake thats been completly reworked by cutting open, reworking the runners and then rewelding that will not show any signes of this being done. the intake can be polished, it can be chromed, it can be plated, it can be powder coated.

so many options. thats what we offer, options that others dont want to offer or cant.

Not needed? I'm just interested and this is not ment for anything other than me speaking my mind...........

BUT.......

Why would you offer a ported head but not offer a matching ported intake? Are you saying the 6.1 intake out flows the stock heads?

You must be..........because if the stock 6.1 intake is the right size for the stock heads, then its got to be too small for a ported 6.1......no?

So either the 6.1 intake is too big for the 6.1 head, or the ported 6.1 heads are too big for the stock intake......but it can't be both right?

A ported 6.1 head flows around 360 - 370 cfm @ .600 at what point do you feel the intake falls short in its present state, in your professional oppinion? Interested in cc - volume.


How would it look??????

It would look factory once you tigged it, ground down the welds, sanded, then polished.

There are only a couple of areas porting would help?

If its ported, it will help everywhere a port would be increased.

So in short, your comments have me puzzled and I was wondering if you would please qualify and quantify.

Extruding is nice for taking off minor amounts of material and offering a polished surface but not to be confused with actual porting where the porter actually can change the taper of the runner, reshape turns, and grind obstructive metal away.

I too would like to see the numbers.........

Cam...........we've been cutting open intakes, porting and rewelding since the late 80's - early 90's with the 2-piece 5-oh motors. (cast GT-40's and stock 5-litre)

For those running metal LS-1 intakes, the process is the same...........still today. With the bent runners, cutting is the only true way to do the job properly...........

In a day in age where we stroke these things to 426ci I am shocked that this method seems obscure to so many people and actually seems like "alot" of work when so many are stroking.

This is nothing we "invented" and no, its no $10K job.

All we were doing was asking the person with the question to please verify what he ment by "porting an intake". Port matching is NOT porting and if we felt Extruding was the end all be all, we'd just send all of our heads to them and be done with it. Alot of people in the business hack up metal and use the Extruder to cover up their work.........

We can actually do this whole job.........

Are we shoing off a bit?

Sure we are.............but if someone is saying they are porting something when all thats being done is port matching, then I wanted to make sure we are talking apples to apples and making sure we are all talking about the same thing.

There are 2 people, as we speak, that have already asked us to consider what it will take to actually port their intakes............this cutting open the intake is exactly what we will do............its an art and not everyone can do it or will do it.

So yeah.............we take pride in stuff like this........this is what we do.

Hey that's some great info! I guess all the intake/head packages that are being offered are just port matched and not fully ported, is this correct? Are there dyno numbers or data showing the actual gains of cutting and porting rather just port matching on the 6.1 intakes?

Actually this isn't exactly true. Not all intake/head packages that are being offered are just port matched.

Power Ported Performance Intake / Head package customers benefit from the enhanced capabilities of our 5 axis CNC porting booths and yes, that's important to note. Why? Because it allows our digitized porting booths (at a cost of roughly $500k each; we have 2 of them) to reach areas that would normally have to be hand ported. Therefore we can accurately CNC port the Intake runners and do so with reliable and more importantly, precisely repeatable results every single time. We also CNC port the Plenum area to clean it up more and allow for smoother airflow. The result is an increase in overall flow numbers by 17 cfm's (@.5 LIFT) and 18 cfm's (@.6 LIFT) for the Intake and Heads combined. And yes, we flowed them across several stock Intake / Heads vs. our CNC Intake /Heads about 7 months ago to get approximate numbers.

It is clear that the increase in flow is beneficial, but it is also important to note that although the 6.1L Intake is adequate for the 6.1L block, it is not ideal. It is my guess that we will see some improved and more performance oriented designs in the future that will allow for better flow on the 6.1L block and for Stroker motor applications.

Our CNC Ported Intakes are $750. We also offer the option of Polishing the Intake as well. Please let me know if I can help answer any other questions.

Sincerely,

Nice input Jeremy............

I think I've said enough and I feel there has been plenty of smoke and mirrors here (as well as good info).

People will have to do some investigating to figure some stuff out on thier own and use some common sence.
