Dude, no offense, but your the only one I see talking about the hoses swelling. All the talk I have seen about hoses swelling is just that, talk. Then to top it off you add in the words "horror stories" here, which to the poor un-initiated reader will stick in their mind. Now I may be wrong here, but I can't think of a single post where someone showed a hose swelling. I watched(with a loaded, spooled engine) and I cannot see evidence of swelling, I'm willing to admit its possible, but from day one with the prototype hoses I haven't been able to find it.
Second, irregular flow. C'mon really? This was brought up in the past and put to rest, as I recall we even linked to an outside source who had done the math(for a different vehicle and a different application, but still a good case study), where it showed that changes in hose volume due to swelling under pressure caused very little change in mass flow rate. Even then, it won't affect m_dot overall but rather initial mass flow in the 0.1 seconds of boost.
B)
How many people still under factory warrantee are questioning purchasing the Samco's? In my mind either you got the hoses replaced with your warrantee, or you believe that buying the Samco hoses will not void your remaining warrantee on other parts. Has anyone ever posted here that the dealer denied warrantee replacement on something else because the Samco's were installed?
Sorry if I sound like a Jackass, I don't mean to, but I feel as if you are bringing up mostly opinion and less facts about the Samco hoses.
racertracer:
The main thing to look at these days is cost, when the Samco's first came out the OEM hoses were total junk, they since have been replaced with a better OEM product that seems to hold up to oil exposure. So now you mostly need to look at the cost of the Samco set, versus the OEM set. IF you need only one hose, it makes for a good OEM argument. If you need/want both, then the Samco's become a more attractive option.
Also, if your the type who is otherwise going to leave the CRD like stock, as in running with your EGR(no ORM), and run without an elephant hose, your going to build up more oil residue, in that case I would say that running the Samco's will give you longer life, if you run without the EGR, and with a Elephant hose, then you will see much less oil, I cannot believe how clean my intake has stayed now that I have been running the ORM for 50k miles.
The only other thing to consider is how long you plan to own the vehicle, if you are thinking of owning it a while, (in excess of a year I'd say), then it would make for a stronger argument for the Samco's.
To be fair for the OEM argument, I know of ONE samco failure, Samco and the vendor were both very responsive and the person was able to get the hoses warranteed. Samco was very interested in getting the failed hose back because they wanted to see the failure and learn how it happened to improve the product. In all my communication with Samco they were responsive and interested in developing the best product possible, if we ever had any ways to improve the production I have no doubt Samco would implement it on future hoses.
That being said, almost 50k miles on the Samco's without issue.
