How crucial are these?

Just I will be buying a new turbo soon, and can get a free silicon turbo intake pipe, or £100 off..........

Are the pipes worth it, or as I'm running out of money now shall I take the £100 off?

 

im sure you can get pipes cheaper then that. i would go with £100 off

 

The pipe is normally around £185 I think.....but not sure if I need it really or not.

 

Mine sounds like Hannibal Lector

It's louder than the DV !

Love it ! I went for the breather delete option to save ingesting smelly oil fumes into the intake ! Needs a catch can too tho'.

P.S. Shame you are so far away, Jap Night @ Squire's at Sherburn in Elmet on Tuesday 7th.

 

Thanks for that mate

This one has it's breather deleted as well......worth it just for the sound do you think?

Yeah, that's Leeds way isn't it, which is a bit far

 

how can ya get sound from just a turbo inlet pipe?

 

Dunno, I fitted both from LATERAL PERFORMANCE, and it does sound mad, I wish KojaK would get round here so I could video it....

LOL

dont think its your turbo inlet hose making noise cause it doesnt do anything but make the air flow a little smoother

 

Sorry mate,

but you could only just hear the turbo with the standard pipe on, then I could hear the original intake leaking, so stuck the Silicon intake pipe on and it's WAY louder than a VTA DV.

Ive just had my turbo removed yesterday to have a bolt hole re drilled and threaded becasue a bolt snapped and now its all back together my car is making this dump valve like noise but only when accelarating hard and well foots on the pedal

Is this what you guys are on about? it never made a sound before the turbo was removed and re-fitted.

 

can you explain how a silicone pipe can be louder than a dump valve?

 

It was quieter before fitting, the standard pipe does a superb job of damping out the noise, acting as a huge restrictor too !

I know it's the turbo generating the noise, but the silicon pipe enhances the level of noise perceived by the pedestrians of this world.

I like the sound of this. By anychance is there any noticeable change in turbo spool up? Thanks.

 

- will be internally optimised re smoothness i.e. as least restrictive to airflow as possible, thus promoting raised gas speeds - slightly more air flow for the same time period.
- tougher than the OEM plastic item, so shouldn't split under significantly raised boost pressures
- sounds good (according to dunx )
- looks good!

 

Nice one, think i'll be on the look out for one this week. Cheers

 

this does not give you any sound, a silicone hose does not give you any noise just smooths air flow into the turbo because i have a perrin one on my car and does not make any noise dont be mistaken by what the above comments say, its the turbo making the noise not the inlet hose!!!

 

I know it's the turbo generating the noise, but the silicon pipe enhances the level of noise perceived by the pedestrians of this world.

Just to be sure !

yes its turbo making noise not inlet hose, if u put this on standard turbo impreza wnt hear anythin

 

A silicone inlet hose does make the intake noisier. For me that's a downside as I prefer quietness, but if you like that kind of thing...

Obviously, it's the turbo spinning up that you hear but it's amplified by the hose leading directly to an open induction cone. The standard OE item which splits and is much more restrictive doesn't do this so much.

 

there is no noise off the inlet hose if you have the oem air box still on

 

Yes there is. I have it with the OE airbox. A lot louder.

 

 

yes it does?? no it dont?? yes, but it does because i hear it?? i no, but i cant so no it dont WTF does it or dunt it, thats the question

 

The question needs to be asked: if the silicone pipes do cause more noise, then WHY do they?

My angle on this, is simply that the OEM pipe has more restrictions to it, not least the 'flexi' corrugated area in the bend. This causes turbulence to the airflow, just like what happens inside intake resonator boxes and exhaust baffles. The reason why designers incorporate these is to cut down on noise, as disturbed, tumbling, slowed-down air makes less noise.

So, by dint of its performance-orientated as-smooth-as-possible design, the Samco (and other silicones) promotes more noise, because they've been designed for more laminar, therefore increased, airflow.

Any takers?

 

Has anyone looked at the entry to the turbo on most silicones? a horrid S-bend that is far worse than the stock plastic part, that IMHO is what lead to the scoobynet project spec C having bad compressor surge, by all means replace the airbox to under manifold section (corrugated and prone to splitting) but the rest of that the OEM part looks better than most the silicon's!

if your going for a silicone inlet hose buy a full air intake to go on end of it if you want proper noise and not a little slight turbo spool which you can barely notice because with stock oem air box and snorkle in the wing you will not hear anything noticeable with a silicone inlet hose, you'll get a slight smoother air flow to turbo just

 

Sounds good to me.

 

I'm gonna look a right **** if I've got the 'science bit' back to front.

 

Well, I've decided to go for the inlet

I have a CAIK as well, so will let you know how things sound. Although, I will be putting a MD321T on in place of a VF35, so that will make the biggest difference over the pipe.
