forge twintake air intake available end Aug 09

[RedRobin]

the flex in the silicon hoses is a good thing as the we know the engine moves around alot, so some "give" is needed from somewhere. If the intake was mounted rigidly to the car body and the intake rigidly to the engine it would be long before something gave way

....Yes, you shouldn't have to dial out all engine movement by going to the added cost of aftermarket engine mounts.

In the case of the ITG, the extra side mounting will help keep the pipework itself stable but not allow it to move too much due to the greater number of silicone components and their tendency to flex.

In the case of the Twintake, necessary allowance for movement is elsewhere and so a side mounting isn't needed (at least in theory until tested < Though already very thoroughly tested by jonnyc and others).

where is that then? , do you mean within the rubber tubing at either end?
  the pipe is only attached at one end to the intake after MAF , and at the other to the front grille /side area.
AFAIK, everything else 'hangs' between those 2 points.....

would that mean that nearly all the flex is going to be occuring on the silcone hose attachment at the turbo.  if something is wiggled for long enough it could end up disconnecting from the turbo.

tprobably unlikely to occur unlessovcer a prolonged period of time, and even less so on a car with engine mounts.

but the standard mounts allow the engine moves round like crazy

....No, as you'll see in my review when it's posted, there are a total of 6 silicone hose sections - Quite sufficient to take up any flexing. The production Twintake is slightly different from the prototypes you may have seen.

Running upstream from the turbo the first is splitting the straight section after the MAF and then one at the side can branch and a further one at each end of each of the two filter cans. All very tidy.

I have been running the Twintake for approx 6k miles now, the last 3k of them have been on stock engine mounts and its 100% fine..

@ jonnyc : Im not saying it isnt ok, just asking the questions.

@ RR : I think youve missed my point Robin , and I have seen the completed article.  maybe I just havent explained it well enough.
           a long piece of pipe is normally supported in someway between 2 end points , either rigid or flexible
           (bit like an exhaust I guess). its just a difference between the 2 kits, Im not pushing either side as better.
           many dont have a support bracket , but then thye dont have as much as 2 filters_casings to support

all good

....I think I see the point you are making but it seems to me that the overall 'load' is spread. Indeed the branch to the headlight serves to triangulate the structure as a whole - like a 'y' - The side branch works like an additional strut. That's the theory but the bottom line is that no breakages have been reported so far after lots of road miles with prototypes.

Got mine fitted this morning absolutly love it!

Got mine fitted this morning absolutly love it!

sounds good mitch, any more info?? sound or power increase??  is you car heathy now mitch we are worried for you!! 

[Janner_Sy]

Got mine fitted this morning absolutly love it!

how is it. did youcome from stock airbox as well. come on do tell??

[MitchGTI]

Well for performance i cant say loads as i was running with a buggerd dv (that was my issue btw not fueling as suspected!)so now its just a completly diferent drive anyway! It does feel very responsive tho! Buuuut! The noise it makes is just to die for its unreal! I love it! The kit itself sits very tidy into the engine bay tho looks very good in the black rather than the polished alloy look as seen at first! Ile try get some pics up its abit hard as time i leave for work and get back its always dark! Ile try tho.... I LOVE IT!
