Hello,

I'm sure I've seen a picture around showing where people have reinforced the Samco inlet pipes to stop them collapsing.....but can't find it anywhere. Anyone got one handy?

 

i was running my old samco inlet pipe sometimes at 1.7 bar boost and never had it collapse.

if it does, am not really sure what you can do to stop it. i wouldnt fancy putting anything on the inside of it incase it gets sucked into the turbo

 

If you put a couple of jubalee clips around it in a few spots!
If the silicone can't warp/flatten then it is a lot less likely to colapse!
I'd also look into a bigger better filter!

Samco have reinforcing steel band embedded anyway, don't they?

Are you saying that it can still collapse (for big power/boost applications), regardless?!!

 

Yes joz they do,cant see it personally,as they are much stronger than the std items,and if samco hoses are collapsing what do you use instead?.I've had 2 samco inlets in the past & both used at 1.4 bar and no probs and extremely stiff.

 

Yeah exactly. If Samco or Viper collapse, then you'd have to move to an all metal job (like the APS item). But none exist for the Classics do they?

But I'm assuming the OEM plastic thing holds up okay (at the expense of being a bit restrictive to airflow...)?

 

This would certainly be a step to help reduce the chances of it collapsing. Higher flowing filter = less of a vacuum being caused.

I have the IM off at the moment, hence upgrading the inlet pipe and as I guess there is no set formula for the jubilee clips I'll just space them out 3-4inches apart. For the sake of a few £'s I think it makes sense.

Thanks all.

 

My Samco inletpipe collapsed as well.
In my case it seems the Apexi conefilter is too small and restrictive.
Maybe if I changed the filter for a more free flowing one, it might have worked, but I went the route of a selfmade ineltpipe made from steel and it works perfect.
In my case the S206 turbo needs more air for sure, but at the moment I have to keep the Apexicone in place to not max the Q45 MAF.
But when my car is working again (destroyed either the middlediff or the clutch at the weekend on the dragstrip) I will fit the big K&N filter in the wing and look, how much boost I can make until I hit maximum voltage of the MAF.
It might be even quicker with less boost, than the restictive Apexi cone and 1.8bar!

 

Am I correct in thinking that higher airflow through a filter = either larger surface area or lesser filtration rate?

Think I might go and see what reviews I can find on flow rates and filtration...

 

Filtration doesn't have to suffer.... so long as the actual filter's achieved its extra surface area by being physically larger (or at least more/longer 'pleats').

Otherwise, if it was the same size/same surface area, then yes, the 'holes' would have to be physically larger, and filtration would suffer as a result...

 

Definitely. So for your typical panel filter upgrade, it either has to have more pleats or do a worse job for filtration.

As I've gone for a Green cotton panel filter I think, just for peace of mind, I'll reinforce the Samco.

 

Maybe.

But any 'shortfall' in dirt particle filtration performance will be negligible, I would've thought.

Certainly not bad enough so as to be detrimental to the engine over the course of its natural life...???

 

I just bought an alloy 90 degree bend and two couplers and four clips....

Saved £230 as well !
