Anatomy of a Ported Short Runner Intake

[nazman]

What is up folks!

Wanted to talk about on how we go about our Ported Short Runner intakes!

As always Nazty Performance is looking for a way to improve our ways and we have done so with our new style, completely modular Ported Short Runner intake.

Now, don’t be scared. This is not your run of the mill ported short runner with massive loss of power/torque down low and mid range and only to have a very narrow and peaky power band.

The way we have designed our ported short runner is to allow us (Nazty Performance) to change the runner configuration even after the intake has been machined! We can tailor runner length, and plenum volume specific for YOUR application, that being Naturally Aspirated, Supercharge, Turbo or Nitrous applications. That means, we take into consideration cam selection and timing, cubic inches, cylinder head work as well as header tubing and collector size! So, this intake will be a fully customized unit to fit your application.

Now, this intake will be very, very helpful for NA, Supercharged or Turbo applications! This intake will provide the user another option to very nice pieces of equipment like the Sullivan, but without the low/mid range power losses associated with them while maintaining a stock like drivability, tenability and TB location…..and did I mention….it looks like a stocker for that extra sleeper mode!!!

This ported short runner will show little to no losses down low and mid range and bring home huge gains over a stock or stock ported intake from stock motored, very mild (bolt-on) or all out NA applications and will pick up huge gains on boosted applications!!

This intake will continue to effectively extend your power band by a good 1000-1500 RPMs depending on cam selection and application, again, with very little to no losses down low or mid range! Allowing for brutal throttle response and will aid with faster turbo spooling!!

Also, another very important thing is that you will NOT need an aftermarket hood to make it fit! So, your stock hood will be more than enough! If we need to add plenum volume, we don’t go up into the hood…we go down into the “lifter valley”! lol!

We at Nazty Performance start with a stock basic “C-Head” (99-01 Cobra, 03-04 Marauder or Mach 1) Core. We machine the stock lower plenum off, and we begin our machining process. We utilize a 3 axis CNC Mill and CAD program for the machining. So, our cuts are very accurate and able to do them exactly the same over and over again!

Runner length and plenum volume is calculated and new runners/bell mouths are custom formed with our very own dies of 5051 aluminum. This again, allows for exact tolerances and measurements. Runner entrance radius and runner taper are taken into consideration when we fabricate our runners!

Plenum volume is calculated and a new plenum is build off aluminum 6061 aluminum for strength.

After that has been calculated and the runners have been pressed. We proceed and fully port the upper intake plenum six feeder ports, and we fully reshape them, then the runner’s injector bosses and runner is fully ported and reshaped and the velocity stacks are attached and epoxied into place.

Then we utilize our dies and cut off a piece of sheet metal aluminum and “end caps” specially molded to clear the runners and to a specific lower plenum volume.


Then, they are hand fitted and TIG welded!

After the TIG weld process the intake is hot tanked two times, and high pressure air “blown” (lol), from there we coat with 1000F ceramic and you get what we call…..a “Nazty Ported Short Runner” intake!

All Nazty Performance Ported Short Runners are serial numbered and documented for our customers!


So, there you have it!

Just another option for your Naturally Aspirated, Supercharged or Turbo combination that utilizes the stock TB position and will not require an aftermarket hood or aftermarket fuel rails!

Estimated time to fabricate a custom Nazty Performance Ported Short Runner is ~three (3) weeks. We also have a few cores that we can send to you for little or no down time and you just swap and send us your stock core! This is a courtesy to our Nazty Customers and free of charge…..keep in mind you MUST pre-coordinate with us before hand for that service and its only when they are available.

If you guys have any questions please don’t hesitate and post or email me at for more specific details at:

Here are a few pics!

We start with a fresh stock intake:

Thru the entire machine process we are always double checking the specs and fitment:

Fully machined Nazty Intake, about to receive the custom lenght runners!!

http://i358.photobucket.com/albums/oo27/stang32v/Slide13.jpg?t=1242413025


Here is one of the custom runners bell mouth/runner. We adjust the lenght to control total runner lenght. All our intakes are modular and runner lenght could be ajusted even after the intake is build and shipped. So, if the intake would need adjustment it could be done, or if you further up-date your combo as in cams or a Blower or Turbo...we could adjust that for you as well!

Nazty Intake starting to take form! Intake runner bells custom pressed of 5051 aluminum, they are installed fitted before expoxing into place.

http://i358.photobucket.com/albums/oo27/stang32v/Slide25.jpg?t=1242413371


All Nazty Performance intakes receive extensive upper plenum modifications! Feeder ports are fully radius and fully ported! The plennum volume is increased and polished.

http://i358.photobucket.com/albums/oo27/stang32v/Slide5-1.jpg?t=1242413612



The other portion of the runner is also worked! The injector bosses are fully reshaped and the injector discharge area is unshurounded (SP?) to clear the injector and aid with fuel atomization!

After the upper plenum, injector boss area and runners are epoxied and cured. We being with the lower plenum and sealing of the intake!

http://i358.photobucket.com/albums/oo27/stang32v/Slide37.jpg?t=1242414179


Finally, the intake is serial numbered to document the runner lenght, intake bell mouth ID and taper ratio as well as plenum volume! Then its ceramic painted!

For those concerned with the "Area Under the Curve" gains/losses. here is one before vs. after of a Mach 1 (same motor as the Marauder). The Mach was equipped with 4.30 gears and the before runs was with an already ported intake. The only change was the Nazty Ported Short Runner!

There you have Folks! The Anatomy of a Nazty Performance Ported Short Runner Intake!

These bad boys have shown gains of 21+RWHP and 20+RWTQ on a stock Mercury Marauder, those gains were over a ported intake! Gains over a stock intake are estimated of 30+RWHP by 5500RPMs!!!

Cost for a Nazty Performance Ported Short Runner is: $899.95 + S&H

Post your coments and or questions! Ill do my best to answer them!

Naz

[W4LTD]

Your own chart shows about a 17 HP gain in 4th Gear (5200-6800 RPM) -- for $900.00?


http://i358.photobucket.com/albums/oo27/stang32v/StockPortedvsNazPortedShortRun nerAr.jpg?t=1242414390

[nazman]

Please understand that those are AVERAGE gains thru that ENTIRE RPM range. Not at a single point on the RPM range.

If we take that same combo, at 6800RPMs gained a whooping 52RWHP over the ported intake!!!

Naz

Here is another on a stock Marauder.

Before and after with no tune changes. Ported intake vs. Ported Short Runner:

http://www.naztyperformance.com/03-04%20Marauder_Nazty%20Ported%2 0Short%20Runner%20vs%20Ported% 20Intake.jpg


15RWHP @ 4600 RPMs
21RWHP @ 5500 RPMs

Keep in mind, this is OVER an already ported intake!!! So, you are looking at 30RWHP gains with nothing more than the intake!

With tune, and exahust mods the intake will bring home even bigger gains!

Naz

[ImpalaSlayer]

sweet, always cool to see what my intake looks like

[Blackened300a]

I have a spare lower intake just sitting in a box I could send out and have zero downtime.

I guess putting a N/A in the 12's will require some spending and its looking like it will take my 293 RWHP in the 310 RWHP range, possibly more.

Email sent.

[Dobs]

Very informative post.

Thanks

[ctrlraven]

Every time I see this intake......

[Zack]

Kinda makes me want to go back to NA and rediscover new mods.
Hmmmmm.

Now Rex, dont try and get me to sell my Eaton conversion to you. :D

[Glenn]

There is no denying Naz makes a beautiful product. Some yungin may well use it to break the NA 12s. But, we will see. I'm not writing my $100 check just yet.

I belive the intake with your supporting mods could be worth easy .3th and 3MPH.

Putting you way close to the 12.99 mark and breaking the 100 MPH barrier.

Its going to take 103MPH and a 1.9x 60 to get the Marauder into the 12 second zone!

You have to launch her as high of an RPM as you traction will allow you!

Hey Naz could you elaborate on the epoxy process and the type of epoxy used? Have there ever been any problems with the epoxy and heat?

[nazman]

The epoxy is 500F and oil/fuel resistant. We have been utilizing it for several years in diferent projects and never had single failure with it.

Naz

[musclemerc]

Thanks for clearing that up for me Naz.

[Dobs]

Naz

Several mean, 2, 5, 10, 15... 20 years?

Thanks

[nazman]

Several mean, 2, 5, 10, 15... 20 years?

Thanks

I have utilized that same type of epoxy for several years on diferent types of projects. How many years? Dont know exactly....3-4 years.

Folks,

Keep in mind that the "runners" are pressed and interference fitted. We chill the runners and press them. They chances of them becoming lose are slim…we utilize the epoxy for peace of mind and as you can see, it’s a minimal amount.

Ok, this answer best my worries about the epoxy. :up:

[musclemerc]

BTW Naz your cobra sounds sick, there is nothing like the sound of wicked bumpsticks when your at a stand still. I've been looking at the HCI with the stage 3 set up but i like to turn my own wrenches my last question is how hard is it to do a cam swap on our mod motors? I used to swap cams in pushrod 5.0's back in the day but is this something someone would want to try on the first time on a 32V?

im with you man, these 4vs intimidate me, lots going on with lots of expensive parts

[Blackened300a]

I would imagine timing the engine is the hardest part of the install and I wouldnt dare attempt it by myself.

[TAKEDOWN]

... and how much $$$ would something like this cost?

[ImpalaSlayer]

i paid 900 for mine

[Zack]

I would imagine timing the engine is the hardest part of the install and I wouldnt dare attempt it by myself.

99% do not time (dial in) the cams and have no problems.

Timing the engine is easier than changing the oil.

[RWR]

That is some incredibly good looking work, Naz.

for the guy asking about cams. it's even more important to dial your cams in when running N/A. when counting each and every pony, it makes no sense to leave power on the table.

[nazman]

Cam selection is critical within any build up....but Ill have to agree, on NA form cam selection is extremly important.

You can always mask a poor cam or a power producing problem with boost but, when working all motor you have to have everything straight.

At Nazty Performance we take cam selection seriously and we advice on what the best aproach/option for his/her cam selection.

As far as performing a cam swap on our beloved 4V, its not as dificult as it may seen.

But timing the cams properly, its beyond critical. Just being one tooth off will cost you 20-25RWHP.

Plus, degreeing the cams should be a must (not necesary) but for all out performance is a must.

Its just matter of having the right tools:

4V Spring Compresor
Cam Holding Tool
Cam Syn Tool
TDC Tool

Basic tools and a weekned.

Naz

[nazman]

Here is another one I just received on my phone (Im currently on vacation in PR).

Awaiting for the full dyno sheet to be emailed. Just off the dyno!

Power coming on sooner and flat as hell all the way to the capability of the cams! 32RWHP by 6900RPMs! Completly stock short block.

Could you try not to always throw stones @ other members. Please try to knock it off. :beer:

[BigCars4Ever]

This mod coupled with a gear vendor to keep the motor in the high rpm's could find the 12's

[Glenn]

In all honestly, what does the IT really contribute below 5,000 rpm to launching off the line - HP? It's a top end mod!

Glenn Ford

no :flamer:

[Joe Walsh]

In all honestly, what does the IT really contribute below 5,000 rpm to launching off the line - HP? It's a top end mod!

Glenn Ford

no :flamer:

When I launch off the line I preload my TC to 2,500+ and after I top out 1st gear my Marauder never sees less than 4,800+ rpm.
So, for drag racing, Naz's intake would work great.
It's the daily driving, idle -> 3,000 rpm torque that worries me.

Glenn Ford

no :flamer:

Once an engines volumetric efficiency has been maximized with available bolt-ons, the only way to achieve more power is by increasing efficiency at higher RPM's. It's what serious hot rodders have been doing for decades. If a person wants they can capitalize on the high RPM efficiency with more gear, but it's not neccessary. With this intake MM's can now utilize better cam profiles as well. This intake opens up power potential not previously available to the MM crew. 12's will go down easy.
