Hey folks,

Well, outside of all of the other probs I'm facing with getting my built motor running properly, I'm pretty sure my turbo inlet is collapsing when I push past 15lbs as all the signs point to it. I guess 22lbs on a 55 trim turbo is too much :D. Its already the 6ply newer version, i've got a free flow cone filter on it and I've already clamped it off on the outside with 4 clamps but its feels like its still collapsing (drop off in power @ 5krpm, 5 lbs and noticable soun difference through the intake and some vibration). Don't want to get into details as I'm pretty sure that's whats happening but wanted to offer and alternative fix and get y'all's thoughts on it:

There have been many posts that suggest using the hose clamps on the outside @ points which look suspect to collapse. When looking at the hose clamps, I realzed that if I turn the clamp inside out, I can have a smooth edge facing out that I can use the screw to both (obviously) change the diameter size both wider and narrower.

With this in mind, how dangerous would it be to mount a few clamps INSIDE the inlet and then tweak the screws so it widens out and pushes against the inner walls of the turbo intlet. This seems like it would definitely gurantee no collapse but i'm a bit concerned about these clamps breaking up and getting sucked through the turbo into the engine. I know I can expand them out so its very tight but how safe do you experts think this would be?

If I'm crazy, please let me know as I think I'm gonna try this this weekend but I don't need to build another motor here...:lol:

I wouldn't want something inside there.

Verify your setup is collapsing by watching it while on a dyno or use a small video/web camera while your friend drives.

Have you considered a hard pipe like the APS inlet?

nope, I'm at wits end as I've put too much money in already and just want the damn thing to work with the parts I got. Might try a piece of pipe like someone here suggested.

How old is this inlet?

I ask because I want to try to determine if its one of the older designs or newer.

its not a problem with the inlet, its a problem with your intake. your intake is obviously creating a restriction on your inlet tract.

That isnt always the case. I have seen hoses collapse on short rams with clean filters.

Its a newer one and this is probably an anomaly but sucks none the less. Pulling the mani off tomorrow to see if I can get enough re-enforcement with the ideas here and other places that I've gathered and will report back on how it worked out...

make an stiff wire "exoskeleton" and bond it to the outside somehow.

2.5-3" worm clamp or T-bolt clamp around the area that collapses will work no problem.
