Hi Guys,

I just received my Perrin intake kit from MAP for my IX and noticed when looking in the turbo intake tube the surface didn't appear to be very smooth and some rubber at the hole locations was sticking out into the airstream. The rest of the kit looks great but I was expecting smoother features on the inside of the tube that would help promote better airflow.

Has anyone noticed something similar on their Perrin intake tube? Is this common on all rubber/silicone intake tubes?

Thanks!

 

I have the samco intake tube and it looks just about the same, my only concern in regards to your perrin tube would be those silicon residues, they might get sucked into the turbo, just remove them before installation and you are good to go. The only requisite an intake tube must meet is it must be rigid and not collapse under suction. I don't think it is crucial for it to be smooth, piping after the turbo is another story...

 

I can probably get an x-acto in there to trim the excess, just wasn't sure if this was normal on their intakes.

 

Im sure its fine but I personally dont like stuff like that. You just never know if it comes off and gets sucked into the turbo it could be bad news. As I said, probably not likely though.

 

Both my Upper and Lower Samco radiator hoses (silicone based) didn't resemble such residue. They were nice and smooth from end to end! Maybe it's a manufacturing defect thru whomever makes the Perrin Inlet? and although its not something of huge concern once removed with an x-acto knife it's not something the buyer should have to do and put up with.

Their kit does quote: The PERRIN inlet hose is perfectly smooth on the inside.

In the end it's an easy fix, so if you don't feel like going thru the hassle of a complaint then just do it yourself, be careful not to poke any extra holes, mount that baby on, and call it a day bud.

 

They all come like that. Like you said, take a razor blade and trim off any excess that you're uncomfortable with.

 

Of course a radiator hose will be smooth, you can't compare it to the intake hose, which has ports (for DV and solenoid hose)...
I do have the samco intake hose, but can't removed it now to check, it's irrelevant anyways, since the OP needs someone with a PERRIN intake tube to compare it to his

 

I'll trim it to make sure nothing goes through the compressor wheel. Kinda annoying I get to do it and not the manufacturer but not a huge deal.

Is there any data out there on effects of turbulent flow upstream of the turbo? Maybe this is a topic for the advanced forum...

Thanks for the input.

 

Look, I understand the Perrin intake inlet has aditional ports, I'm not stupid LMFAO...all they do is embed an insert in the silicone to create that nice sturdy BOV port or in your case Diverter Valve. Keep in mind that because they modify the intake inlet for different applications, it doesn't neccesarily mean Quality should be compromised!! Technically they should both be smooth in and out regardless a radiator hose or intake inlet & yes, you actually can compare them both dude. Let me give you 2 examples. #1 They are both made out a near similar Silicone Resin. #2 Both have wire fibers embedded in the silicone to add for support, so don't come at me with your nonsense acting like you the boss when both items (radiator hose & intake inlet) are comparable.

Also, I clearly understand that the OP is looking for someone that has a similar setup to compare his to but that doesn't mean the EvoM community can't give their input on a similar product.

Peace

 

You had a bad day? no one called you stupid, and I didn't come at you with any nonsense or acting like anything, you need to take your attitude elsewhere.

All I was saying was that the radiator hose is all smooth inside because it doesn't have any ports added to it, if the intake hose didn't have those ports, it would be smooth, just like your radiator hose. Hence why the two should not be compared.
Want another reason? rad hose is made to carry high temp/pressure liquid, intake hose just feeds air to the turbo.


Peace

 

Nope, had a good day to be honest. Regardless of the ports or not dude residue leftover from the fusing of the insert and silicone should not exist. It's a Quality Defect and a Process Indicator that should be addressed and brought up for future cases. Sure, it is an easy fix but like the OP said...it's kinda annoying he has to do it himself and not the manufacture of the intake inlet!

I never mentioned you called me stupid, I'm letting you know I'm not stupid. There is quite a difference lol. Also I understand the purpose of both items very clearly

 

Well we finally agree on something: the intake pipe should not have those defects ( when did I said differently?)

As soon as I have my car available, I will remove my intake pipe and take a look, now I wonder if the samco intake pipe has those defects...

 

I wouldn't touch it. if you do, you pretty much screwed yourself the option of returning it.

 

I'm going to send the pics to Perrin and see what they think before I do anything. I don't want a defective intake tube on my ride or one with quality defects.

 

Yeah, it's the smart thing to do. It's hard after getting excited about new parts. Believe me, I just went through that recently with my new laptop.
