ID of samco hoses?

rwppowerful · **Posted:** Sat Oct 26, 2013 9:34 pm

Just as it says, what is the ID of the samco hoses. I need the measurements for both hoses. They look quite a bit bigger than the stockers, thats for sure, and Im on a mission to be a cheap arse. I have a bunch of intercooler/exhaust pipe lying here in my garage, and im thinking I can make my own and save $200+.

Did you see improvements with the reponse and power from the motor after swapping them?

Thanks

Functional ID is controlled by the OD of the flange each end of the hose(s) attach to which is easy enough to measure. There is a post, I lack the link, to a DIY setup that involves bent piping but you still have to have flexible ends and in this case the builder used short lengths of Samco hoses if I recall correctly. Not sure it's worth the effort but that's your call.

No increase in power. Only real reason to switch is to prevent lose of boost due to oil rotted OEM hoses.

I felt an increase in throttle response and no more oil seeping through the walls of the hose.

I thought an increase in throttle response would be noticed. (factory hoses expand some while boost builds) I have piping and the silicone couplers for the ends. Ill be honest I thought about it after i hit the post button, that duh it would be regulated by the OD of the intercooler ends, throttle body, and turbo measurements.

Halfway down this thread Tony P. gives the measurements for the hose ends.

Someone once calculated what the volume of expansion of the hoses is, as compared to the volume flowing through them at full boost, and it's essentially nil. Basically there can be no noticeable increase in throttle response. The placebo effect is strong though.

^ LOL thats pretty funny

That's all well and good if the comparison is done with hoses that are both non porous.

But you are not comparing apples to apples if you use and OEM hose VS a Samco.

When one hose is old and porous (original OEM) and the other is not (SAMCO) then you will definitely see a difference.

The Samcos increased my throttle response, no loss of boost anywhere.

The OEM shot oil out through small perforations, leaky oil oozed out everywhere.

The Samcos are as tight as a horses arse. I believe that using steel tubing would be even better.

racer is likely right for the circumstances he posts. However, I'm big on getting ahead of the curve on preventive maintenance for known failure points hence I replaced my 05s OEM hoses long before they got anywhere near the porous soggy with oil and leaking boost stage. That may be why I did not notice any change in throttle response.

While it's hard to argue with your logic the reality is that these porous hoses are, to all intents and purposes, airtight until they split. Any loss of boost is negligible to the point that you would not be able to perceive a performance difference.

It's a bit like claiming that if you drilled a 1/64 hole in one of the major North American oil pipelines you would be able to measure the loss by comparing oil in versus oil out. Yeah the guy whose back yard the hole is in is going to have a fine oil film over his property but no one else is going to be any the wiser. While the leak is very real you just can't measure such a small percentage loss.

Yeah, well you can say all you want...... the bottom line is that throttle response is stiffer and it is noticeable.

Dirtmover, do you have Samco Hoses installed in your rig?

No, I'm still on the original hoses.

I'm not disputing the fact the you perceive a difference.

All I'm saying is that it's for some reason other than the fact that the OE hoses are porous to oil.

To the original post, as CATCRD added the size to the ports are in the link attached.

As to the rest, since my post was mentioned more than once, I'm flattered. I like to fix things right the first time around.

Questions to ask yourselves. How long will I keep the crd? How many times will I have to replace the boost hose and spent x number of dollars (again), and have to limp home, park it until ??? (I keep a set of sleeves under the seat just in case, cheap insurance)

If we could replace the timing belt with a chain, would you?
If we could replace the window regulators with a system that works, would you? The list goes on, etc...

It's obviously an improvement, the tubes will probably outlast the jeep.

@CATCRD the pill works for some of the people.

If my CAC hoses went out today, I'd definitely buy Samcos. OTOH, my hoses were new (better composition), fuel head new, etc. . . so I've logged 40k miles on the new version OEM CAC hoses with no problem.

IMHO, if you bought a second hand CRD from an owner that was absolutely raped by the original dealer for 'service and parts' you may not have the problems others do.

Of course, YMMV
