whats the deal dude?

Brian at Posi Performance will port your Eaton and your intake. I'm not sure about doing the short runner thing, but he does porting!
 
those welds are crap trust me ,i hope you guys have been installing these intakes and following the correct torque pattern? as this could also put stress on this intake
 
What is on the other side? Is there an opportunity to have it welded on both sides if you attempt to have it repaired. Could the fill be too high doe to improper prep like no edge prep to allow proper penetration? (Ha, I said penetration)
 
Hey guys,

I have been in contact with a Mach I owner with a Naz PSRI and yes he has experienced the same thing; however once it was fixed he made great power from it. Its too bad I think he does have a product once repaired is great.

And yes I spoke to him at length a few weeks back and his health issues must be taking its toll on him.....If I were in that same situation I wouldn't focus too much energy on repairing intakes.

When put into perspective he has bigger problems than broken intakes.

With Naz PSRIjcitroloc (JeromeMach1) (405/360 SAE) 5.0L BB/Ported 03 Mach C head/MP cams/Naz PSR Intake. see post 355, p.11 for details.

With Ported Intake
jcitroloc (JeromeMach1) (372/363 SAE) 5.0L BB/Ported 03 Mach C head/FR500 cams & valvetrain/Ported Intake.

I just spoke to the guys over at MMR and they are going to port my intake to match my setup. I guess in the end its a win, win. I am saving over 500 plus the piece of mind of my NEW motor not blowing up. Guess its time to look at some shorty headers.....LOL

I dont doubt the power that the intake makes. I noticed it and I even gauged it against a mustang I raced a bunch of times. Before the intake I would take him off the line and then around the 75mph, he would start to pull on me and pass me. With the intake, I still take him off the line and he barely pulls on me now.
It just sucks that I have to dump more money into a item that should be failproof.
 
Quote from earlier post: Welds look horrible, you can see the crack dipping into the crater in a couple spots. That's bad because there shouldn't BE a crater in the middle of the weld. Heck, there shouldn't even be one at the end of the weld. Welds cracking down the middle indicate that being the weakest spot, plain and simple.
And for what it's worth, TIG and MIG were changed years ago to GTAW and SMAW, when it was realized that not all gases used for shielding are 'inert'. Who's yo daddy now? Me, that's who.:D
__________________
Response: TIG is "GTAW", but MIG is not "SMAW" in the context written. MIG should never be used in these applications. TIG is a much superior method of welding, with less heat introduced to the product/parent material, which is a major issue with metallurgy (stresses). TIG take a lot longer to perform, much a much nicer job in all categories.
SMAW is Submerged MIG Arc Welding. It would be impossible to SMAW this part at ANY reasonable cost.

No such thing as failproof bro.

Not on this Earth, Doomie.....

I'm loving the welding talk this has developed, but hating the reasons why.
It's a shame it's happening and it's made worse in that we don't know the full story as to Carlos' situation .

So what are you going to do with yours Paul?

Im pulling it off and then have to find someone to replace the tin metal with some thicker metal and re-weld it. Thicker steel will eliminate the noise and prevent cracking. Then I can re-install along with my exhaust and get the car tuned.

You mean thicker aluminum plate, right?

Yeah it is sad, I hear from the MACH I guys that the gains were substantial......its too bad. I think its just a materials and welding issue that once corrected "can" be a great product. There are really no competiters out there besides PHP and Sullivan. Someone here should buy his designed and re-market to the Cobra 99 01/Mach I/Marauder guys.

Welding inspector here. Generally, the weld looks ok as far as fusion properties. The problem with this weld, and many welds made on thin metals, is a condition called excessive re-inforcement. The crown height(laymen's terms, bead thickness above base metal) is too big. This causes what is known as a stress riser at the toes (sides) of the weld which pulls each side away from the other. Add some heat, and it'll pull hard enough to crack the weld at approx. the center. A little time with a grinder, reducing the crown height and smoothing a little along the weld toes would have prevented this. A good rule of thumb for weld crown height would be 1/4 the thickness of the base metal (the 2 components welded together). All you backyard welders should pay heed. Sorry to say, but this weld should be totally removed for a proper repair. Just welding over the crack will only further crack the weld, and quite likely the base metal.

great post, I used to have that same job..it's really difficult to tell a welder that is twice your age that you have to grind that out and do it again...lol

third party inspection FTW
 
welding inspection

I also am an inspector for all petro-chemical applications. And yes, you are right, it is very difficult to tell seasoned welders to rework a weld. It was harder when I was 25 years old, but now at 55 years old, age and experience have their advantages. A good welder can save anybodies butt.
 
Not to bring up a sore subject but has there been any resolution on this either as far as repairs, replacement, or refunds? Just haven't heard anything in awhile...
