see below for contact info. are you using the stock intake (airbox,snorkle, elbow). also, using stock turbo, right? who installed it?

the place you bought it from should be able to help get a replacement...

i think the consensus as to the cause of the collapsing was the type of air filter used. If the filter is too restrictive, the inlet colapses due to the suction.

If you put a hose clamp on it where it collapses it will keep it round instead of it going oval when it collapses. Just make sure you dont make it too tight.

Samcos and AVOs dont have this problem


But hey, we should have to modify OUR cars to suit an inferior product design right? I mean thats cool right?


Moral of the story??

When there are numerous reports of GPmotos colapsing, and a few reports of Perrins colapsing, and no (or basically no) reports of collapsed samco or AVO inlets, you should buy a quality part to begin with and pick the ones that ARENT collapsing.

Any moron who is doing the labor of a turbo inlet hose and running the stock airbox is wasting there time/money anyway. Chances are Perrin quality control never tested sucking all that air through the restrictive stock airbox and the turbo inlet.

In other words, the inlet hose is not being used as it is supposed to be. For they price of the AVO or Samco, they should include a toothless hooker for an hour.

It doesnt matter what intake you run. I have seen it collapse with stock air boxes, shortram intakes, and cold air intakes. It isn't a matter of what intake you run, it is a flaw in the product. I have seen Samco and AVO inlets run with the same intake and same boost and I have never seen or heard of one collapsing.

I don't think you should call anybody a moron for using the stock airbox with the inlet.
For the price of the Samco you Do get piece of mind that it won't collapse...worth it.

Fmowry, I think you are the moron. I guess 150 lower rmp spool is a waste of time and money? Oh and btw ive tried putting on a k/n short ram before even posting on here and guess what it still collapsed So fmowry what do you have now? NOTHING you just have to face it your wrong, you have no idea what your talking about, and you just have to relise that somethings have defects. Jeff is taking care of it which is great. Nuff said
And one more thing fmowry Dont post back untill you have had your car putting down 430 whp on a set up you custom designed from scratch terd ball. I think i know what im doing unlike yourself.

bottledigger -> sorry, but when there was no mention of intake as a mod I didn't want to just assume that meant the stocker was still being used.

RANT -> I understand that Matt has seen the Perrin collapse under multiple conditions (different intakes). I know that Daveknow loves to come off as super critical (that is putting it nicely). And I can very easily believe that the Samco or AVO have a superior design that will hold up to more internal pressure. What I don't understand is why we haven't all come to a consensus yet that regardless of the Perrin being 'easier' to collapse, we still don't agree that the stock airbox is a bad idea when upgrading turbos. We still see more collapsing with the stock intakes, and there were previous tests posted on here (not the most well-rounded tests, but worthwhile) showing the pressure caused by the stock intake, yet NASIOC still hasn't agreed to light into people for using the stock intake with a bigger turbo. You can get a decent short ram for around $130, and your engine WILL thank you for it in the long run IMO. Can someone please explain why with all of the critical people around here (like Daveknow) more people to try to convince others to get rid of the stock intake? I know that some of that steams from the WRX days were they could bump up more HP without as much of a problem, and the fact that it doesn't really add much more HP. But it would seem like things such as cylinder pressure would be reduced, and that can help your engine run a long healthy life.

Or am I just a jaded NASIOC poster expecting more flaming without reason

Hey bottledigger, please make sure to post back your results when you get a new inlet hose. I am assuming Jeff is sending you a new one? It will be nice to see if it collapses as well or not. This could lend proof that it is a manufacturing defect instead of a design flaw (maybe).

I have had mine on 2+ years with no problems so far and my car is very far from stock. I have used 4 intakes plus the stock box as well.

I second that.... are you watching it on a dyno or is some other on-road phenomenon happening? I have a Perrin hose and am ignorant as to whether it's collapsing or not.

Care to share your dyno sheet showing the 150 (RPM, not rmp) lower spool? I'm talking an A-B with the exact same mods except the turbo inlet. You won't share it, because you don't have one. Unless Perrin hid it somewhere, it doesn't exist. Why should I take the word of someone who is doing ass-backward mods to a car? The intake is restrictive, period. I proved it on my car with the stock box and the green. Removed the KN filter from the airbox and the boost shot up.

If you custom designed a 430 whp system using the stock intake, your design skills suck. You didn't list your mods anywhere, you don't have them in your sig, and you don't show them. I tend to not search threads from posters with 2nd grade writing skills who can't use punctuation. Do you want a cookie for making 430? Who gives a crap? I made 280 whp in a 1.6 Miata back in 1999. Did you? If your skills were so good you'd tell your friend who you're installing the inlet pipe for that he's killing performance by running the stock intake unless he's running the stock turbo, in which case the Perrin inlet is still a useless, expensive mod.

Tundra and Trevor723.
The symptoms of a collapsing hose are a dropoff in boost above 6k and the MAF readings falling on their face.

fronk my simple minded friend, 1 no i didnt use the stock air box to make 430whp. And I do want a cookie for making 430 because unlike most roted or bolt ons people put on, I make my own 1 of a kind kit. 280whp on a miata wow, what parts did you custom make? Did you put togeather your 1 of a kind custom turbo, did you make and weld your own uppipe to suport an external wastegate, did you make your owe fmic piping, how about an intake did you make one of those your self, doubt it. 430 is pretty easy to get to, but not many can make their own deal and do it thats the point im putting across oh and this was on 93 piss gas.

As for using the stock intake im using, there is no way im going to put on a aftermaket intake because im putting my car as close to stock as i can get. As for the other 2 Ive put them (inlet hoses on) they dont have an after market intake because they are using the stock turbo and want to spend money on parts that decrease spool.

Like i said frank the wanta be tank, dont write back in my thread, Pm me if you have issues such as lack of self esteam.
